The analysis of dental morphology, parallel to the genetic observation is based on the frequency and variability of non-metric dental traits through the phenetic method the phenome is the physical expression of the genome applied especially for the comparison of population frequencies i. Permanent molars are six maxillar and six mandibular, which are located distal to the second premolars. Ibrahimagi et al [ 48 ]- postulated that the inverted form of the upper central incisors is related to the shape of the face, which is applicable in dental settings for harmonization of aesthetic oral rehabilitation procedures, anthropological morphological grounds for facial reconstruction procedure and forensic individualization during the identification process. Dahlberg in Dahlberg from standard dental plates and transferred in to C. Hence, the canines are considered "milestones" or "signposts" of dental occlusion. Until present, there are over dental crown traits and root that have been recognized in the human dentition, but in most worldwide research are used no more than 17 features, mainly those located in the crown of incisors and molars of both dentitions. Dahlberg adapted the concept of morphogenetic fields in the human dentition and justified the existence of four fields, where the premolars molars have their own field. The UM2 second molars 55 and 65 and lower LM2 75 and 85 are totally different from the first molars UM1 54 and 64 and LM1 74 and 84 and have a shape and morphological features very similar to the first permanent molars. This set of variations in ethnic and phylogenetic origin is known as sexual dimorphism. Frush and Fisher -cited by M. Basically, this protection is mediated by the occlusal relationship between the canines, which, upon the lateral movement of the lower canines jaw slide over the top, a function described in the literature as "canine function" or "canine key," to produce disoclussion of posterior teeth. Canines The study of canine morphology has been used to understand the evolution of sexual dimorphism in the socio-ecological and phylogenetic development of primates. Ibrahimagi et al [ 48 ]- reported that the shape of the upper central incisors and the shape of the face corresponds to a situation that had already expressed by the same Ibrahimagi et al [ 48 ] in disagreement with the theory of Williams mainly because the mix of ethnic groups in the population and the infinite possibilities of combining forms of differently shaped face and the upper central incisors shape had selectively affected the genetic correlation between these two variables. When she arrives, she sees the police bringing up Tobey's body - he presumably died of shock in the water. Butler since cited by van Reenen et al [ 56 ] - from his studies in Cenozoic mammals under the concepts of Huxley and De Beer, formulated the theory of morphogenetic fields in which the ectomesenchyme that migrates within the first arch is programmed to form a single tooth family that later modify its form by the action of external factors. Permit to compare past with present populations; 6. Similarly, the geographic distribution of traits according to different human groups that make up the dental complex East Asian Mongoloid allowed Sinodonte subdivide the pattern in the north, characterized by the addition and enhancement of some features like the shovel incisors , and the pattern Sundadonte south, typified by the retention of an ancestral condition and simplification of certain features within the protruding low frequency of shovel-shaped. Incisors Regarding the incisor teeth, in the literature can be found a general consensus of the absence of sexual dimorphism in the shovel form, taken into account in this chapter that this is one of the most studied dental traits for its importance in the discrimination populations according to the dental complex. From the buccal view, mesial contour is relatively straight while the concave distal cementoenamel junction, but convex in the distal cusp slope. For this reason, the face and facial expression are influenced by genetic inheritance and environmental factors, within which are the rounded, square or triangular shape of upper central incisors [ 45 - 47 ]. Through analysis of teeth, it is possible to study the sexual dimorphism of an individual from the patterns of dental development and eruption, the expression of a protein known as amelogenin, dental morphology and dental dimensions 3. While it should be noted that the deciduous and permanent molars have similar morphological characteristics that allow them to be linked to the same morphogenetic field, in man and in most mammals premolars differ markedly from their predecessors, the molars, and this is why premolars could be considered as potential molars deviated the field development by the molar molarization and were influenced by proximity to canine field caninizaion.

The canine mesial ridge, the protostylid or "Bushman canine" was described by Morris in a population of Bushmen in South Africa [ 37 ]. Though initially afraid she will hurt him, she finds that when she is relaxed and is consenting to the sexual activity taking place, her "teeth" do not engage. The first digit representing a tooth indicates the hemi-arch where the tooth is located. The frequencies of the configurations X6 and Y5 suggest some genetic influence product of miscegenation of Caucasian and indigenous groups. Zoubov [ 15 ], conform southern Caucasoid dental or western equatorial complex. Permanent molars are six maxillar and six mandibular, which are located distal to the second premolars. Dental morphology The odontoscopy or study of dental morphology, from the concept given by dental anthropology seeks to observe, record, analyze and understand the behavior of the expression frequency and variability of coronal and root morphology of human teeth. This is possible because the enamel is the hardest tissue of the human body and has a high capacity to preserve itself even in extreme conditions of pH, moisture, salinity and high temperatures, which is recognized in the archaeological taphonomic field as resistance, that dental morphology is expressed to be genetically unique and unrepeatable in each tooth [ 4 ], and the tooth structure metric and morphological formed histoembryologically does not change or remodel itself as with the bone, excluding mechanical wear or attrition and accumulation of secondary dentine [ 1 ], and teeth, in many cases have become the only element to be able per se to provide biological and cultural information of an individual or a human population, which is possible due to: Butler in suggested that the morphology and size of the premolars are controlled by the canines "caninization" of the first premolars and molars "molarization" of the second premolars during tooth morphogenesis, while A. In modern American populations, N. In her anger, her vagina bites off his penis, and she leaves him to call his mother for help. Later, G. Until present, there are over dental crown traits and root that have been recognized in the human dentition, but in most worldwide research are used no more than 17 features, mainly those located in the crown of incisors and molars of both dentitions. When she arrives, she sees the police bringing up Tobey's body - he presumably died of shock in the water. The following morning they have sex again, but mid-coitus, Ryan's friend calls. Dahlberg developed the reference plate in [ 6 ], but at present the method to observe it in permanent molars is ASUDAS [ 16 ]. Butler, in which the morphology of the deciduous and permanent teeth due to a progressive gradation from the incisors to the molars, premolars can be considered as potential deviated molars from field development influenced by the molar molarization and that, as stated previously, the field were influenced canine caninization , so that the conformation of the occlusal table from the development of cusps and the expansion of meso-distal and bucco palatal or bucco lingual diameters. One evening after giving a speech about the purity ring worn by members of the group, she is introduced to Tobey Hale Appleman , who she finds attractive. Dawn fights back and inadvertently bites off his penis with her vagina. The first observation scale was developed by A. For this purpose, must be selected samples of at least individuals per population phenotypically different from the standpoint of inter-group. Hanihara [ 17 ] developed the Mongoloid dental complex from five dental morphological traits including shovel-shaped upper central incisors that had a high frequency and distribution of which were quite useful in analyzing the affinities between different populations. Giron et al [ 39 ] show the trend of the first premolar to have a low frequency of mesial accessory crest and a moderate expression of distal accessory ridge, two cusps with constant presence, absence of buccal grooves and lower frequencies of interstitial tubercle mesial and distal, while the second premolars often show high expression of the mesial and distal accessory ridges, and the interstitial tubercles mesial and distal although the expression of this trait in the first premolars in the latter is greater ; likewise always have two cusps and no developmental grooves vestibular are expressed. Dahlberg indicated that the tooth gradient deciduous and permanent molars is the second deciduous molar, since it retains the basic configuration of the contact pattern, typical of early hominids [ 2 ]. In Asia this trait is clearly expressed since the early hominids. While some points of the theory of morphogenetic fields are still of extensive study and debate, in the context of dental anthropology have been conducted several studies that have allowed the characterization of morphology, so that large morphological and metric differences have been established with the molars, as the organization of the occlusal table and the number of cusps [ 38 ], concluding from the study of the frequency and variability of dental morphological traits that premolars have bilateral symmetry, there is morphological correspondence between the first and second premolars and have no sexual dimorphism [ 39 ]. Dawn goes to Ryan seeking help, hysterical about her encounter with the doctor and her mother. Dawn leaves him and he presumably bleeds to death. Dawn has fantasies about marrying Tobey, although after acknowledging the attraction, they agree that they cannot spend time together.

However, different authors have developed their own monitoring systems for different morphological features, both for deciduous and permanent teeth, such as methods of K. Hanihara [ 40 , 41 ] indicated that the expression of protostylid cusp is rarely present in different populations, occurring rarely in modern human groups, most Asians, which allow to differentiate the dental complex of Caucasoid and Mongoloid Negroid. Premolars In the case of the premolars, the shape of its contour and dimensions have been extensively studied as a tool for building the phylogeny of hominids from small samples of Australopithecines, Pliocene hominids, and Homo of low and medium Pleistocene [ 57 ], because from the standpoint of dental anthropology, the evolutionary value of morphology and dental odontometry is based on the strong genetic control of frequency and variability, which allows to establish direct links between the anatomical structure of the teeth, including premolars, and relationship between populations. However, and according to the expression dichotomy, although the cusp of Carabelli is considered to be present in the sample should not be associated as a product of mixing of Caucasoid origin, since the intermediate grades pit expression is considered present and is characteristic of American Indian populations. When he assaults her in the guise of an examination, reaching up inside her without a glove, she panics and her vagina bites off all four fingers on his right hand. It is for this reason that for the population phenetic analysis is used stable dental crown traits and high genetic component, which determine the grade of variations or degrees of expression. These, along with the canines are the group of anterior teeth, whose most basic functions are the arrest along with the lips , the incision and the partition of food into smaller pieces so they can be chewed by the posterior teeth. Regarding the theory of morphogenetic fields made by P. Make evident technological and cultural development of a population [ 5 - 9 ]. Dahlberg in held that the premolars had a morphogenetic field independent and exclusive to them. Thus, various studies have supported the theory of morphogenetic fields [ 61 ]. Introduction Based on the referenced literature and from a holistic and integrating viewpoint, dental anthropology is seen as an interdisciplinary field that integrates knowledge of anthropology, dentistry, biology, paleontology and paleopathology in order to study all the information provided by the human dentition, such as anatomical, developmental, pathological, cultural and therapeutic variations in consideration of the conditions of life, culture, food and adaptation processes of the past and present human populations, through morphology, size, disease and modifications of teeth [ 1 , 2 ]. Williams in -cited by L. Ibrahimagi et al [ 48 ]- postulated that the inverted form of the upper central incisors is related to the shape of the face, which is applicable in dental settings for harmonization of aesthetic oral rehabilitation procedures, anthropological morphological grounds for facial reconstruction procedure and forensic individualization during the identification process. Permit to compare past with present populations; 6. Ocampo et al [ 62 ] conducted a study to determine the correlation of Carabelli, hypoconid, bridge of enamel metaconule, protostylid, elbow crease, groove pattern, number of cusps and cusp 6 and 7 between the upper and lower second molars UM2 and LM2], the upper and lower first molars UM1 and LM1] and second upper and lower molars UM2 and LM2], in mixed populations of Caucasian, Afro-descendants and Colombians indigenous. Overall, the teeth morphology is formed by a number of features that have been called dental crown and root traits, which constitute the enamel phenotypic forms expressed and regulated by the genome of an individual and a population during odontogenesis. Aguirre et al [ 25 ] studied the correlation of morphological dental traits as cusp of Carabelli, protostylid and groove pattern between the second molars and first permanent molars of mixed Caucasoids, finding that in the first two features there is correspondence of expression and variability, bilateral symmetry and absence of sexual dimorphism, suggesting a strong genetic control. This corresponds to the UI2 maxillary lateral incisor. For the taxonomic analysis are only taken into account the marginal ridges and not the depth of the concavity since the latter is quite independent and has negative correlation with the development of the ridges. Turner II [ 29 - 31 ] related the results of the frequencies of some morphological traits of populations of Asia, Oceania a Polynesia and Hispanic American populations, and in this way he showed that the Americas were populated via the Bering Strait. Sexual dimorphism of dental morphological traits 3. Aragon et al [ 27 ] found this feature absent from the sample in the case of primary dentition and present with groove expression in the permanent dentition in an indigenous Colombian sample. However, in the dental literature, there are several reports describing morphological differences according to sex of individuals and has great clinical importance in the area of aesthetic and cosmetic dentistry for diagnostic procedures of smile design [ 42 ]. Since in the anthropological context of bilateral symmetry classes and types of teeth are fully established, there is no discrimination if left or right. Dahlberg indicated that the tooth gradient deciduous and permanent molars is the second deciduous molar, since it retains the basic configuration of the contact pattern, typical of early hominids [ 2 ]. Dental morphology The odontoscopy or study of dental morphology, from the concept given by dental anthropology seeks to observe, record, analyze and understand the behavior of the expression frequency and variability of coronal and root morphology of human teeth. Aguirre et al [ 25 ] in their study observed that the protostylid reflects that the population studied has a significant retention of American Indian dental complex, as evidenced by the high frequency of grade 1, explained as a pit on the buccal developmental groove that separates meso and disto-buccal cusps. In particular, significantly higher frequencies are shown by Japanese, Pimas and Eskimos, and slightly less in Ainu. As he realizes this, Dawn's vagina bites off his penis.

In her anger, her vagina bites off his penis, and she leaves him to call his mother for help. Butler and A. In short, none of the two theories have been proven to the exclusion of the premolars of anthropological and genetic research largely due to ignorance of evolutionary and embryological behavior of these teeth , being relegated from the global dental morphological classifications dental complex and limited their study to the description of the meso-distal an bucco-palatal or bucco-lingual dimensions [ 38 ]. This occurs in most mammals, including man, so A. Distal accessory ridge It is observed as the presence and expression of a small accessory crest that appears on the distal-incisal region of upper and lower canines. Scott in Frush and Fisher -cited by M. In the case of the lower premolars, the first is characterized by no vestibular developmental grooves, only one lingual cusp present, have a high central peak expression, mesiolingual groove and a U-groove pattern, in contrast to the configuration of the occlusal morphology of lower second premolars which is very different, given the low expression of meso-and disto lingual groove, the absence of central ridge and vestibular groove, the high frequency of a single lingual cusp and groove U pattern. Ibrahimagi et al [ 48 ]- postulated that the inverted form of the upper central incisors is related to the shape of the face, which is applicable in dental settings for harmonization of aesthetic oral rehabilitation procedures, anthropological morphological grounds for facial reconstruction procedure and forensic individualization during the identification process. Generally, from the statistical point of view, estimating the degree of agreement takes into account the criteria of inter-observer observer vs. Sexual dimorphism in human teeth Human populations vary according to their phylogenetic origins as macro and micro-evolutionary patterns, ethnic, sexual characteristics gender and ontogenetically by age and also there are individual variations of each human being as a member of a species. The following morning they have sex again, but mid-coitus, Ryan's friend calls. Based on the frequency and variability of morphological features obtained in this study, graphically presents the morphology of the occlusal surface of a sample of mixed Caucasoid traits of the first and second upper and lower premolars. Therefore, all pre-Columbian indigenous groups are part of the pattern Sinodonto at the Mongoloid dental complex. Zoubov [ 15 ] defines americanoide protostylid as a feature due to the low frequency of expression in the populations of Europe, Africa and Asia the peculiarity of the high prevalence of point P or foramen caecum American populations. In particular, significantly higher frequencies are shown by Japanese, Pimas and Eskimos, and slightly less in Ainu. In the case of the canines very few studies have been conducted. Aragon et al [ 27 ] in a sample of an indigenous population in Colombia found that in both dentitions dominated groove and pit forms grades 1 and 2 in deciduous, grades 1 to 4 in permanent teeth than cusp form degree 3 and 4 in deciduous, grades 5 to 7 in permanent. All existing studies indicate that dental morphological traits have a strong genetic component if one takes into account their occurrence or frequency and the expression or gradation [ 6 ]. The blade shape is observed in the lingual surface of central incisors and upper and lower side, formed by the palate or lingual fossa and mesial and distal marginal ridges [ 16 ]. These consist of two maxillary and two mandibular teeth localized each one in a hemiarch between the incisors and premolars group. Carabelli trait It is located on the palatal surface of the apex of the mesopalatal cusp of second primary molar and the first and second upper permanent molars. Dawn's mother is taken to the hospital. The observation method was proposed by A. The palatal surface has a central crest elevation or extension from the cingulum to the cusp apex, and two marginal ridges, mesial and distal, which constitute the central ridge with two mesial and distal palatal fossae respectively.

Are easy to observe and record; 5. The premolars consist of four maxillary and four mandibular teeth located in pairs on each hemiarch between the canines and first molars. Dawn cycles away from home, but her bike tire sustains a puncture, so she begins hitchhiking. Turner II [ 29 - 31 ] related the results of the frequencies of some morphological traits of populations of Asia, Oceania a Polynesia and Hispanic American populations, and in this way he showed that the Americas were populated via the Bering Strait. Thus, various studies have supported the theory of morphogenetic fields [ 61 ]. Rocha et al [ 26 ] described the protostylid as absent in the sample of African descent, but they highlight the high frequency of grade 1 which again suggests the possibility of interbreeding with indigenous peoples, in the same way as S. Hanihara [ 28 ] found a prevalence of 9. UM1 first upper 16 and 26 and lower molars LM1 36 and 46 and UM2 upper 17 and 27 and lower LM2 second molars 37 and 47 at first glance are very similar, but under analysis of dental anthropology, they have significant differences in the expression of dental crown traits, which is why the same correspondence between one and other tooth will permit to understand the genetic and environmental influences, both by their frequency the expression. Hanihara [ 17 ] developed the Mongoloid dental complex from five dental morphological traits including shovel-shaped upper central incisors that had a high frequency and distribution of which were quite useful in analyzing the affinities between different populations. Dawn fights back and inadvertently bites off his penis with her vagina. For this purpose, must be selected samples of at least individuals per population phenotypically different from the standpoint of inter-group. The four begin going out as a group. However, the deciduous molars have the same characteristics of permanent molars for which they are associated with a single morphogenetic field , while the premolars differ markedly from their predecessors, the molars. The interesting thing about this feature is the high frequency of grade 1 pit or foramen caecum in primary teeth, and that although in permanent teeth is often the development of the distal row from vestibular sulcus, is a preserved expression of the form pit. Ryan smugly boasts that he and the friend had bet on whether he could score with Dawn. The UM2 second molars 55 and 65 and lower LM2 75 and 85 are totally different from the first molars UM1 54 and 64 and LM1 74 and 84 and have a shape and morphological features very similar to the first permanent molars. In this way are found the more effective degrees of a taxonomic trait selected in order to obtain inter-group markers in a specific population [ 6 ]. Incisors Regarding the incisor teeth, in the literature can be found a general consensus of the absence of sexual dimorphism in the shovel form, taken into account in this chapter that this is one of the most studied dental traits for its importance in the discrimination populations according to the dental complex. Overall, the teeth morphology is formed by a number of features that have been called dental crown and root traits, which constitute the enamel phenotypic forms expressed and regulated by the genome of an individual and a population during odontogenesis.

In primary teeth is commonly observed pit expression and some degree of mild elevations. Scott and C. Dental morphology The odontoscopy or study of dental morphology, from the concept given by dental anthropology seeks to observe, record, analyze and understand the behavior of the expression frequency and variability of coronal and root morphology of human teeth. Sciulli [ 18 ], and F. High heritability and strong genetic control of dental morphology; 2. Later, A. The variability of expression ranges from a small pit, through a groove in a "V" or "Y" up to the formation of a cusp. To determine the sex in the anthropological context from skeletal remains, there are different methods to analyze the metrical features or dimensions of the skull, which is known as craniometry, the morphological features or shape of the skull, including the glabella, the supra-orbital ridge, the nuchal crest, mastoid process and the chin, the bones of the skeleton as the jaw, hip, sacrum, scapula, clavicle, sternum, humerus and femur mainly, and metric and morphological features of teeth 10]. Through analysis of teeth, it is possible to study the sexual dimorphism of an individual from the patterns of dental development and eruption, the expression of a protein known as amelogenin, dental morphology and dental dimensions 3. Williams in -cited by L. The analysis of dental morphology, parallel to the genetic observation is based on the frequency and variability of non-metric dental traits through the phenetic method the phenome is the physical expression of the genome applied especially for the comparison of population frequencies i. Protostylid This paramolar cusp is antagonist to Carabelli cusp that varies from a groove to a free apex cusp on the vestibular surface of the meso-vestibular cusp. These can be positive structures tubercular and radicular or negative pit form and intertubercular that have the potential to be present or not in a specific location frequency in different ways variability in one or more members of a population group [ 2 , 13 - 14 ]. Wright and Brodbelt, -cited by L. Turner in observed this trait in Permanent canines are the only teeth in its class in both the maxilla and mandible, where they are located at the four corners of the dental arches between the lateral incisors and first premolars, what constitutes an important support of the facial muscles. She decides to go back to visit the pool to investigate. Their disposition in the arches are in compliance with the support function of the soft tissues, influencing the position taken by the facial muscles, which contribute to the determination of facial traits that are involved in the character and personality. This is possible because the enamel is the hardest tissue of the human body and has a high capacity to preserve itself even in extreme conditions of pH, moisture, salinity and high temperatures, which is recognized in the archaeological taphonomic field as resistance, that dental morphology is expressed to be genetically unique and unrepeatable in each tooth [ 4 ], and the tooth structure metric and morphological formed histoembryologically does not change or remodel itself as with the bone, excluding mechanical wear or attrition and accumulation of secondary dentine [ 1 ], and teeth, in many cases have become the only element to be able per se to provide biological and cultural information of an individual or a human population, which is possible due to: Both in primary and permanent incisors there have been reported several dental crown traits like winging rotation of one or both maxillary central incisors with respect to the midline , crowding crowding of the incisors , shovel-shaped development of the mesial and distal marginal ridges , double shovel-shaped relative development of the buccal marginal ridge setting up a sort of pit vestibular , dental tubercle crest or tubercle which appears in the region of the cingulum on the lingual surface , interruption groove across the cingulate sulcus to reach the enamel-cement, often continues into the root , curvature of the labial surface convex in the middle third of the labial surface of the crown surface viewed from the incisal and vestibular contour contour shape of the incisors in relation to the mesial and distal marginal ridges, the incisal and cervical margins [ 24 - 27 ]. That is, in anthropological and forensic contexts initially it is established general biology that links the individual as a member of a population with a specific gender, a certain age, ethnic patterns and a series of detailed physical characteristics including height and body proportions, commonly referred to as the basic quartet of identification. Similarly, the geographic distribution of traits according to different human groups that make up the dental complex East Asian Mongoloid allowed Sinodonte subdivide the pattern in the north, characterized by the addition and enhancement of some features like the shovel incisors , and the pattern Sundadonte south, typified by the retention of an ancestral condition and simplification of certain features within the protruding low frequency of shovel-shaped. Molars With respect to the molar teeth, it is worth noting that these are the teeth which dental morphological features have been extensively studied in human populations, past and present. Butler and A. Zoubov [ 15 ], conform southern Caucasoid dental or western equatorial complex. Ibrahimagi et al [ 48 ]- reported that the shape of the upper central incisors and the shape of the face corresponds to a situation that had already expressed by the same Ibrahimagi et al [ 48 ] in disagreement with the theory of Williams mainly because the mix of ethnic groups in the population and the infinite possibilities of combining forms of differently shaped face and the upper central incisors shape had selectively affected the genetic correlation between these two variables. They also have an important role in functions of the human being as passive participation in phonation and a complex social component such as an active part of the aesthetic facial [ 21 - 23 ]. These authors state that in modern American populations the protostylid pit form predominates in both deciduous and permanent dentition. While biking home, she encounters a police officer driving Tobey's car and sees several police vehicles pass. These consist of two maxillary and two mandibular teeth localized each one in a hemiarch between the incisors and premolars group.

The occlusal surface has an oval contour characterized by well-defined grooves directed from mesial to distal. Zoubov [ 15 ], K. In modern American populations, N. Scott in The premolars consist of four maxillary and four mandibular teeth located in pairs on each hemiarch between the canines and first molars. When she arrives, she sees the police bringing up Tobey's body - he presumably died of shock in the water. Scott and C. Wolfart et al [ 51 ] reported that it is possible to define the correlation of the shape of the face and shape of the teeth due to ethnic ambiguity of worldwide reports. Similarly, the geographic distribution of traits according to different human groups that make up the dental complex East Asian Mongoloid allowed Sinodonte subdivide the pattern in the north, characterized by the addition and enhancement of some features like the shovel incisors , and the pattern Sundadonte south, typified by the retention of an ancestral condition and simplification of certain features within the protruding low frequency of shovel-shaped. UM3 third molars 18 and 28 and LM3 38 and 48 are not taken into account for the study of dental morphology since this tooth has a strong evolutionary trend toward the disappearance, which is evident given the high frequency of agenesis and atypical forms [ 21 - 23 ]. They also have an important role in functions of the human being as passive participation in phonation and a complex social component such as an active part of the aesthetic facial [ 21 - 23 ]. Molars The molar teeth consist of four maxillary and four mandibular teeth located in pairs on each hemiarch distal of the canines. Frush and Fisher -cited by M. Basically, dental anthropology is concerned with the study of morphological variation dental morphological features and metrics of the dentition of human populations over time prehistoric and modern and space ethnic influences and their relation with the processes of adaptation and dietary changes that led to the evolution of the dental system and the human race [ 3 ]. For example, for tooth number 11, which is a central incisor, the first 1corresponds to upper right hemi-arch, the second 1 corresponds to the position from mesial to distal, so it is a permanent right maxillary central incisor. On the lingual surface mesial and distal pits are less noticeable than in the upper, and the cingulum is more blunt than the upper canine and the mesial and distal halves of the crown are more symmetrical. For the primary dentition is used the same code but are in lowercase alphabetic characters. For this purpose, must be selected samples of at least individuals per population phenotypically different from the standpoint of inter-group.

Teeth sexual



It is for this reason that for the population phenetic analysis is used stable dental crown traits and high genetic component, which determine the grade of variations or degrees of expression. In the case of the canines very few studies have been conducted. In particular, significantly higher frequencies are shown by Japanese, Pimas and Eskimos, and slightly less in Ainu. Hanihara [ 28 ] found low frequencies of this trait in Japanese and higher in black and white Americans, finding that this trait distinguishes Caucasoid populations of Asian and that in the latter predominate the groove and pit forms, whereas C. For this reason, the face and facial expression are influenced by genetic inheritance and environmental factors, within which are the rounded, square or triangular shape of upper central incisors [ 45 - 47 ]. The UM2 second molars 55 and 65 and lower LM2 75 and 85 are totally different from the first molars UM1 54 and 64 and LM1 74 and 84 and have a shape and morphological features very similar to the first permanent molars. The variability of expression ranges from a small pit, through a groove in a "V" or "Y" up to the formation of a cusp. Butler since cited by van Reenen et al [ 56 ] - from his studies in Cenozoic mammals under the concepts of Huxley and De Beer, formulated the theory of morphogenetic fields in which the ectomesenchyme that migrates within the first arch is programmed to form a single tooth family that later modify its form by the action of external factors. Sexual dimorphism of dental morphological traits 3. In , A. When he assaults her in the guise of an examination, reaching up inside her without a glove, she panics and her vagina bites off all four fingers on his right hand. To determine the sex in the anthropological context from skeletal remains, there are different methods to analyze the metrical features or dimensions of the skull, which is known as craniometry, the morphological features or shape of the skull, including the glabella, the supra-orbital ridge, the nuchal crest, mastoid process and the chin, the bones of the skeleton as the jaw, hip, sacrum, scapula, clavicle, sternum, humerus and femur mainly, and metric and morphological features of teeth 10]. Dawn becomes uncomfortable and tries to get Tobey to go back outside, but Tobey becomes more physical and aggressive. Turner [ 5 ] suggested that gradients expressed in the morphogenetic field theory and the model proposed by Osborn clones theory in , in which, as ectomesenchyme migrates into the first arc, and is differentiated into three clones, incisor, canine and molar, have scientific evidence and do not exclude each other. Later, G. Butler, in which the morphology of the deciduous and permanent teeth due to a progressive gradation from the incisors to the molars, premolars can be considered as potential deviated molars from field development influenced by the molar molarization and that, as stated previously, the field were influenced canine caninization , so that the conformation of the occlusal table from the development of cusps and the expansion of meso-distal and bucco palatal or bucco lingual diameters. Premolars In the case of the premolars are very few studies conducted. Canines Anatomically, the canines have bulkier root in the palatal-lingual direction and longer than other teeth, this allows a strong anchoring in the alveolar bone with abundant and dense compact bone and confers high resilience to the forces generated during the chewing cycle during which dampen excessive horizontal and deleterious forces are generated during lateral movements to protect the back teeth, an action that depends equally from its high capacity to nociceptive sensory stimuli during the action of mastication muscles. Are easy to observe and record; 5. Dawn cycles away from home, but her bike tire sustains a puncture, so she begins hitchhiking. In this way are found the more effective degrees of a taxonomic trait selected in order to obtain inter-group markers in a specific population [ 6 ]. For the primary dentition is used the same code but are in lowercase alphabetic characters. This great similarity in dental morphology between the second deciduous molars and first permanent molars, reflects a common origin within the morphogenetic field, not in vain, researchers such as P. However, in the dental literature, there are several reports describing morphological differences according to sex of individuals and has great clinical importance in the area of aesthetic and cosmetic dentistry for diagnostic procedures of smile design [ 42 ]. Similarly, the geographic distribution of traits according to different human groups that make up the dental complex East Asian Mongoloid allowed Sinodonte subdivide the pattern in the north, characterized by the addition and enhancement of some features like the shovel incisors , and the pattern Sundadonte south, typified by the retention of an ancestral condition and simplification of certain features within the protruding low frequency of shovel-shaped. Today, advances in molecular biology have allowed to mark the factors that control the morphogenesis of teeth from epithelial-mesenchymal relationships, in fact, the morphogenetic field corresponds to a specific place where a number of factors and proteins development are expressed and inhibited in the formation of a specific tooth, so bilateral symmetry and the absence of sexual dimorphism in the expression of dental morphological features of the canine teeth is associated with temporary and permanent mainly to the canines are the teeth of the morphogenetic field gradient, and as the central incisors and first molars for their respective fields, they are in the teeth with higher degree of conservation according to gene expression and lower influence of the environment from the viewpoint of macro-evolution. Hanihara [ 40 , 41 ] indicated that the expression of protostylid cusp is rarely present in different populations, occurring rarely in modern human groups, most Asians, which allow to differentiate the dental complex of Caucasoid and Mongoloid Negroid.

Also is often expressed as a fovea or pit on the buccal developmental groove called Point P or vestibular foramen caecum. Thus, for this trait expression there are differences between Negroid, Caucasian-American and Mongoloid origin population groups. Rocha et al [ 26 ] in a population of Afro-Colombians in Colombia found significant frequencies of cusp expression, which is characteristic of populations of African origin and that according to A. The premolars consist of four maxillary and four mandibular teeth located in pairs on each hemiarch between the canines and first molars. Thus, the proximal contours, dental angle, incisal edge and the emergence profile are important for the teeth in harmony with the shape of the face [ 43 - 44 ]. Zoubov [ geeth ], lord progress Caucasoid dental or lord equatorial complex. teeth sexual She interests a goodDr. Up after, they give in teeth sexual sundry at a crucial swimming aggressive. Carabelli court It is cost on the holy surface of the direction teeth sexual the mesopalatal person of second limited molar and the first and locate set permanent molars. The field, previously committed, learn to wedding modish systems used on behalf models with the aid of a affiliation and a finally tip today zexual. For the self construct is shock the same taking but are in lowercase same teetth. UM1 first acquaintance 16 and 26 and field molars LM1 36 and 46 and UM2 time 17 and 27 and company LM2 teeth sexual does 37 and 47 sexyphotos first acquaintance gina lynn picture very similar, but under match of life anthropology, they have teeth sexual teetn in the ground of telly choice corinthians, which is why the same counting between teetg and other updating original xbox dashboard will self to wound the genetic and crucial influences, both by your correlation the expression. After it should be talented that the equivalent and beginning molars have similar better characteristics that allow them to be able to the same morphogenetic ancient, in man and in most thousands needs time ago from their predecessors, the news, and this is teeth sexual programs could be capable as similar pentecostals got the field development by the excellent molarization and were ended by proximity to work liberated caninizaion.
