Medidas orofaciais em nipobrasileiros após crescimento puberal

OBJETIVO: descrever medidas orofaciais em nipobrasileiros após crescimento puberal e verificar diferenças entre medidas de mulheres negras, brancas e nipobrasileiras. MÉTODO: a casuística foi composta de 90 sujeitos japoneses ou descendentes de japoneses, sem histórico de miscigenação, ambos os sexos, entre 20 e 50 anos, sem queixas ou atendimentos fonoaudiológicos atuais ou prévios em motricidade orofacial, sem tratamento ortodôntico atual e sem alteração cognitiva. As medidas avaliadas foram: lábio superior, lábio inferior, filtro, terço superior da face, terço médio da face, terço inferior da face, lados da face, abertura máxima de boca e abertura máxima de boca com a língua na papila. O instrumento utilizado foi o paquímetro eletrônico digital da marca Jomarca. Os dados foram comparados com os achados na literatura referentes às mulheres negras e brancas. RESULTADOS: os dados coletados mostraram homogeneidade entre as medidas; os valores para todas as medidas foram maiores nos homens, com relevância estatística positiva. As diferenças mais significantes entre as negras, brancas e nipobrasileiras foram: terço superior e filtro das nipobrasileiras menor do que de negras e brancas. Para o terço médio não houve diferença estatística significante. O lábio superior das nipobrasileiras é maior do que das brancas e o lábio inferior das nipobrasileiras menor do que das negras. Lados da face sem diferenças estatísticas. CONCLUSÃO: foi possível verificar que as médias das medidas foram sempre maiores nos homens, que houve relações significantes entre algumas medidas orofaciais e que houve diferença estatisticamente significante entre as estruturas das brancas, negras e nipobrasileiras.PURPOSE: to describe orofacial measurements in nipobrazilians individuals after pubertal growth and to verify the differences among black, white and nipobrazilians women measures. METHOD: the sample was composed by 90 Asian, Japanese and Japanese descendants, with no history of miscegenation, both genders, from 20 to 50 years old, with no complaints, current or previous speech therapy in orofacial mycology, not being orthodontic treated and with no cognitive impairment. The evaluated measurements were: upper lip, lower lip, philtrum, upper face, middle face, lower face, sides of the face, mouth aperture and maximum aperture of mouth with the tongue in the papilla. The instrument used was a Jomarca digital caliper. The data were compared to black and white women findings from the literature. RESULTS: collected data showed homogeneity among the measurements; the values for all measures were higher in men, with positive statistical relevance. The most significant differences among black, white and nipobrazilians were: smaller nipobrazilian's upper third and philtrum than in black and white women. There was no statistically significant difference for the middle third. Nipobrazilians upper lip was bigger than in white women and nipobrazilians lower lip was smaller than in black woman. Face's sides did not show statistical differences among ethnic groups. CONCLUSION: in the studied sample it was possible to verify that the averages of the measurements were always higher in men, there were significant associations among some orofacial measurements and there was statistically significant difference among the structures of white, black and nipobrazilians women

Relationship between head posture and dentofacial morphology in patients with TMJ osteoarthritis/osteoarthrosis.

AIM: To test whether there is a relationship between head and cervical posture and dentofacial morphology in patients with temporomandibular joint osteoarthritis/osteoarthrosis (OA). METHODS: The subjects consisted of 34 Japanese females with TMJ OA (aged 24.7 +/- 6.1 years). Six craniocervical angular measurements were constructed for head posture. Two angular and 6 linear measurements were constructed for the skeletal relationship, while 1 angular and 6 linear measurements were constructed for the dental relationship. Pearson correlation coefficients were calculated between head posture and dentofacial variables. RESULTS: In the skeletal relationship, increased craniocervical angulations were significantly associated with a more posterior position of the maxilla, a decreased Frankfort to mandibular plane angle, decreased mandibular length, and a decreased lower facial height. In the dental relationship, increased craniocervical angulations were significantly associated with more posterior positions of the anterior teeth to the basal bone and decreased alveolar height of the anterior-posterior teeth. CONCLUSION: The hypothesis was rejected. These results suggest that an association may exist between head and cervical posture and dentofacial morphology in patients with TMJ OA.link_to_subscribed_fulltex
