“…Studies on the analysis of the face morphology of Asian populations showed mouth width values and upper lip vermillion height greater than those found by this present study [10,13,18], while the studies on Black and White Americans observed mouth width values more similar to those of the Brazilians and Peruvians [11,17]. The vestibular shift of maxillary incisors and canines can affect the upper and lower vermilion areas of the lips [20], therefore the assessment of the upper anterior teeth shapes is important to the study of lips stereophotogrammetry, especially when comparing different ethnicities, which may present different trends of dental positioning [21].…”

“…The 3D stereophotogrammetry is the technique most used in current studies because it enables measuring variables with image depth, e.g. : volume, and linear/angular measurements [6,9,12,[17][18][19]. Table 2 displays the studies used in this discussion and the measurements found by the authors and the comparison with those of this present study.…”

“…Small alterations in face structures greatly impact on the face harmony. Many studies analyzed the face structures alone, based in different populations [9,11,[16][17][18][19]. The 3D stereophotogrammetry is the technique most used in current studies because it enables measuring variables with image depth, e.g.…”

Objective: To compare the proportion and linear measurement indexes between Brazilian and Peruvian population through 3D stereophotogrammetry and to stablish the face profile of these two Latin American populations. Material and Methods: 40 volunteers (Brazilian n = 21 -10 males and 11 females; Peruvian n = 19 -8 males and 11 females) aged between 18 and 40 years (mean of 28.7 ± 9.1) had landmarks marked on the face. Then, 3D images were obtained (VECTRA M3) and the indexes of proportion and linear measurement (face, nose, and lips) were calculated. The data were statistically analyzed by One-Way ANOVA (p < 0.05). Results: The proportion indexes did not reveal marked differences either between the studied populations or genders (p > 0.05). The following linear measurements showed intergroup statistically significant differences: face width and height, nose width and height, upper facial height, mouth width, protrusion of the nose tip (p < 0.05). The Brazilian females showed the smallest significant differences. Conclusions: Despite the different ethnic compositions, the Brazilian and Peruvian populations did not differ regarding the proportions of the face, nose, and lips. The differences observed in Brazilian females may be related to gender and/ or to the Caucasian heritage of the Brazilian sample. ReSumoObjetivo: Comparar índices de proporção e medidas lineares da face entre amostras de populações brasileiras e peruanas por meio da estereofotogrametria 3D, a fim de estabelecer o perfil facial destas duas populações latino-americanas. Material e Métodos: 40 voluntários (21 brasileiros -10 homens e 11 mulheres; 19 peruanos -8 homens e 11 mulheres) com idade entre 18 e 40 anos (média de 28,7 ± 9,1) tiveram pontos de referência marcados na face, foram então obtidas imagens 3D (VECTRA M3) e calculados índices de proporção e medidas lineares da face, nariz e lábios. Os dados foram analisados estatisticamente por meio de ANOVA One Way (p < 0,05). Resultados: Os índices de proporção não revelaram grandes diferenças entre as populações analisadas ou entre gêneros (p > 0,05). As medidas lineares que apresentaram diferença significativa na análise intergrupos foram: largura e altura da face e do nariz, altura da face superior, largura da boca e protrusão da ponta do nariz (p < 0,05), sendo que as brasileiras apresentaram as diferenças mais significativas em relação aos demais grupos, com medidas faciais menores. Conclusões: As populações brasileiras e peruanas, apesar das diferentes composições étnicas, não diferem quanto às proporções de face, nariz e lábios. As diferenças observadas no grupo de brasileiras podem estar relacionadas ao gênero e/ou à maior descendência caucasiana da amostra quando comparada à população peruana.

“…For example, the mandible breadth of Chakma females was almost similar to Santhal 12 , Manchu 13 , Evenks 14 , Mongol 15 , Korean 16 females. Three-dimensional data collected by digital indirect anthropometry were reported by Sawyer et al 17 for adult Caucasian and by Sforza et al 18 for white Italians. In comparison some values were larger some were smaller than the current ones.…”

Background: It is well accepted that a single standard of craniofacial norms is not appropriate for application to diverse racial and ethnic groups, even for different sex and ages in same ethnic group. So it is necessary to develop craniofacial norms for different groups based on above factors. The present study was designed to establish the baseline measurements of the lower jaw and orolabial anthropometrical parameters and indices, and also to evaluate the differences (if any) on age related morphological variations of adult Bangladeshi Buddhist Chakma females. Methods: The study was descriptive, observational and cross-sectional in nature with some analytical components. The study group consisted of a convenient sample of 100 adult Bangladeshi Buddhist Chakma females; categorized into two groups -25 to 35 years (n = 70) and 35 to 45 years (n = 30). Variables were measured using physical and photographic procedures. Indices were calculated from those variables. An independent "t" test was performed to evaluate if there was any significant difference in measurements between the two age groups setting a p value of <0.05 as statistically significant. Results: All measurements show statistically non significant difference between two age groups except philtrum length (p = 0.02) and upper vermilion height to philtrum length index (p = 0.03). Conclusions: The result of this study can be useful for anatomists and anthropologists to serve as a basic framework for estimating the standard of lower jaw and orolabial dimensions of this population and also to compare the craniofacial dimensions of other ethnic groups of Bangladesh with this ethnic group.

IMPORTANCE Aesthetic proportions of the lips and their effect on facial attractiveness are poorly defined. Established guidelines would aid practitioners in achieving optimal aesthetic outcomes during cosmetic augmentation.OBJECTIVE To assess the most attractive lip dimensions of white women based on attractiveness ranking of surface area, ratio of upper to lower lip, and dimensions of the lip surface area relative to the lower third of the face. DESIGN, SETTING, AND PARTICIPANTSIn phase 1 of this study, synthetic morph frontal digital images of the faces of 20 white women ages 18 to 25 years old were used to generate 5 varied lip surface areas for each face. These 100 faces were cardinally ranked by attractiveness through our developed conventional and internet-based focus groups by 150 participants. A summed ranking score of each face was plotted to quantify the most attractive surface area. In phase 2 of the study, 4 variants for each face were created with 15 of the most attractive images manipulating upper to lower lip ratios while maintaining the most attractive surface area from phase 1. A total of 60 faces were created, and each ratio was ranked by attractiveness by 428 participants (internet-based focus groups). In phase 3, the surface area from the most attractive faces was used to determine the total lip surface area relative to the lower facial third.
