Why does blacks have big lips

Just in general people were making horrible assumptions about me. An inspired Korean style outfit! Not really Obviously, there's work to do. But in the face of all that, she remains resilient, and only hopes that more people understand that not only is the journey to loving yourself a long one, but a necessary one too. The biggest weapon you can use against those who feel obligated to comment something negative about you is your confidence. Because trust me, they find it intimidating finding someone not self-loathing and letting people's judgment not get to them.

You can hear more of what Jacinda has to say about her lips and her journey here :. On Friday, Jacinda adultsdrink posted an image of her lips with the text, "When you realize having big lips is a trend but it took you a while to love your natural ones…" Along with the photo she wrote, "At this point in my life I'm like, 'No one's gonna love and appreciate each flaw and imperfection or feature that you possess.

We asked Jacinda to elaborate on her post and what it was like to see big lips become a trend when she had spent years being insecure about hers. For you.

Upper and lower lips were more protruded in blacks than in whites. The present study found a bimaxillary skeletal, dentoalveolar and soft tissue protrusion in black Brazilian subjects compared to white Brazilian subjects, both groups with normal occlusion.

Upper and lower lips showed to be more protruded in blacks, but lip thickness was similar in both groups. It is known that a single standard of cephalometric variables is not appropriate for application to diverse racial and ethnic groups, and that normative data of cephalometric measurements are essential to precisely determine the degree of variation from normal 14 , Orthodontic treatment must be in equilibrium with the normal growth process to be effective and stable and to compensate for unpleasant facial patterns.

The impact of treatment on the face has been constantly questioned. The age and the race became indispensable features The cephalometric norms are not applicable to all patients because of the racial characteristics and the miscegenation, bringing the need for specific cephalometric standards to different ethnic groups 1.

Cephalometric norms of different ethnic groups must be interpreted with caution. American blacks are an admixture not only of the different races in the United States, but also come from different parts of Africa 7. In the same way, Brazilian blacks had their origin mainly from the African coast, where Bantu population is prevalent. Some studies demonstrated significant cephalometric differences between South African, American blacks and whites, due to interracial and intraracial variations in morphological characteristics 2 , 5 , 11 , The black subjects generally present a dental camouflage to compensate an anteroposterior discrepancy of skeletal bases, providing a good facial balance 5.

Enlow, et al. In blacks, the mandible develops downwards in a greater proportion than in whites. However, other studies found a bimaxillary protrusion characterized by dentoalveolar flaring of both maxillary and mandibular teeth with resultant protrusion of the lips and convexity of the face in black subjects 4 , 11 , 15 , Considering the factors involved in ethnic facial features, it becomes important to study the Brazilian population considering the respective somatic traits.

The present study aimed to cephalometrically compare skeletal, dentoalveolar and soft tissue characteristics in two distinct ethnic groups: black and white young Brazilian subjects with normal occlusion. The tested null hypothesis was that the cephalometric characteristics of black and white young Brazilian subjects with normal occlusion are similar.

The sample comprised the lateral cephalograms of white and black untreated young Brazilian subjects presenting normal occlusion and well-balanced faces. All subjects presented all permanent teeth up to the second molars and normal occlusion, i. Their data were collected some years ago when there were lighter restrictions on human studies. The subjects of both ethnic groups were selected as pure as possible from the same geographic boundary, and the parents of each correspondent subject were from the same ethnic group.

The Brazilian black subjects had their origin mainly from the African coast, where Bantu population is prevalent. Brazilian whites were Mediterranean descents. It is important to study the population characteristics and the origin of the Brazilian ethnic groups, analyzing the respective somatic traits.

Other relevant factor is the historic mixture of innumerous populations and races in America, which hinders the biological definition of each group The miscegenation in Brazil among the Portuguese, the indigenes and black individuals resulted in the formation, since the early times of History, of a diversified population. Each one of the three basic groups is far from representing a pure ethnic group.

By the geographic origin, one can have an idea of the racial affiliation of the imported individuals of the black group. In the African coast the Bantus are predominant, who were selected by the present sample, formed by the mixture of nigricians and paleonegroids, divided in occidental, oriental and meridional, with great or less influence.

The Brazil stands as one of the few American countries that received African people of all origins. Three regions of Africa, the west, center-west and southeast coasts contributed with slave workers to Brazil until Regarding the cephalic index and stature, the following ethnic groups were distinguished in the Negroid group:. The Nigrician, with high percentage of tall and dolichocephalic individuals; concentrated in Sudan and Guinea;. The Paleonegroid, with high percentage of short and mesocephalic individuals; concentrated in the forest regions of Congo, Senegal and Angola;.

The Nilotic, with really tall and dolichocephalic individuals; dispersed in regions of High Nilo and great lakes;. The Khoisan, with high percentage of short and mesocephalic individuals; dispersed in South Africa, as well as the forest and desert regions. F- Numonics Corporation, Montgomeryville, Pa. These data were then stored on a computer and analyzed with Dentofacial Planner 7.

Skeletal, dentoalveolar and soft tissue cephalometric measurements are shown in Figure 1 and less usual variables are shown in Figure 2. Less usual cephalometric variables: 1. Nasolabial angle 0 ; 2.

Soft tissue convexity 0 ; 3. Upper lip length mm ; 4. Upper lip protrusion mm ; 5. Lower lip protrusion mm ; 6. Upper lip thickness mm ; 7.

Lower lip thickness mm ; 8. Interlabial gap mm ; 9. Upper lip-E mm ; Lower lip-E mm ; Line E Ricketts esthetic plane. The mean and standard deviation SD for the ages and for each variable were calculated for both groups. Normal distribution was verified by the Kolmogorov-Smirnov test.

The results of the tests were non-significant for all variables. Therefore, intergroup comparisons were performed by independent t tests. All statistical analyses were performed on Statistica software Statistica for Windows 6. After 1-month interval from the first measurement, thirty randomly selected cephalograms were retraced and re-measured by the same examiner LMAF.

The random errors varied from 0. GoGn to 0. Only one angular variable SN. Ocl and two linear variables 1-NB and UL thickness presented statistically significant systematic errors. From the 28 measured evaluated, only two presented systematic errors: SN. Ocl and 1-NB Table 1. These results demonstrated that These errors were comprehensible, because it is known that there is great variation in the determination of the mandibular incisor root apex.

Black subjects presented a significantly more protruded maxilla and mandible and a greater maxillomandibular anteroposterior discrepancy than white subjects which had a more vertical growth pattern.

Chin prominence was larger in whites. Facial convexity was greater in blacks than in whites. The maxillary and mandibular incisors were more protruded and proclined in black subjects. The nasolabial angle was greater in whites than in blacks. The upper lip was longer and both upper and lower lips were significantly more protruded in blacks in relation to white subjects. And all of these differences were statistically significant Table 2.

Lightness did vary in the study. The vermilion zones are always darker than the perioral skin, except in African American women, Ms. Baras said. Capacitance was measured with a corneometer.

Capacitance, which reflects the water content in the skin, was significantly stronger in the vermilion zone, compared with the perioral skin. In addition, there was a "big difference" in transepidermal water loss measured with a VapoMeter, she said. The lower lip lost significantly more water than did perioral skin.

Interestingly, this water loss did not significantly differ with age, she noted. Aging did modify other lip and skin properties.
