Resumo: | Objective: This cross-sectional blind study aimed to verify differences in odontometric measurements of premolars according to sex. Methods: Teeth size values were established for males and females based on a sample of 100 pairs of plaster models (50 from each sex) from dental students. Upper and lower, left and right, first and second premolars were examined with regard to their mesiodistal and buccolingual measurements and the distance between homologous premolars in each quadrant. Parametric tests were used with a 5% significance. The 95% confidence interval was determined to assess the differentiation power of each tooth. Results: There were statistically significant differences in all measures among the second premolars, with higher values in men (p<0.05). Among the first premolars, sexual dimorphism was found in the teeth 24 (mesiodistal length) and 34 and 44 (buccolingual length). As for homologous teeth, there was a significant difference between upper and lower premolars (p <0.001), with no distinction between right and left sides. The 95% confidence interval showed no overlapping values, thus indicating sex dimorphism in the mesiodistal measure of tooth 15 and in the buccolingual measure of teeth 15 and 34. Conclusion: We conclude that the tooth 15 has the greatest potential for sex dimorphism, which could be utilized for human identification in sex determination based on mesiodistal (females: 6.40 to 6.63; males: 6.64 to 6.89) and buccolingual (females: 9.28 to 9.54; males: 9.56 to 9.88) measurements. |

Métodos: Os tamanhos dos dentes foram estabelecidos para os sexos masculino e feminino com base em uma amostra de 100 pares de modelos de gesso (50 de cada sexo) de estudantes de Odontologia da Universidade Federal da Paraíba. Os primeiro e segundo pré- molares, superiores e inferiores, esquerdo e direito, foram examinados em relação às suas medidas mésio-distal, vestíbulo-lingual e à distância entre os pré-molares homólogos em cada quadrante. Testes paramétricos foram utilizados com significância de 5%. O intervalo de confiança de 95% foi determinado para avaliar o poder de diferenciação de cada dente. Resultados: Houve diferenças estatisticamente significantes em todas as medidas entre os segundos pré-molares, com maiores valores nos homens (p<0,05). Entre os primeiros pré-molares, o dimorfismo sexual foi encontrado nos dentes 24 (comprimento mésio-distal) e 34 e 44 (comprimento vestíbulo-lingual). Quanto aos dentes homólogos, houve diferença significativa entre os pré-molares superiores e inferiores (p<0,001), sem distinção entre os lados direito e esquerdo. O intervalo de confiança 95% não mostrou valores de sobreposição, indicando dimorfismo sexual na medida mésio- distal do dente 15 e na medida vestíbulo-lingual dos dentes 15 e 34. Conclusão: Nós concluímos que o dente 15 tem o maior potencial de dimorfismo sexual, podendo ser utilizado para identificação humana na determinação do sexo com base nas medições mésio-distal (feminino: 6,40 a 6,63; masculino: 6,64-6,89) e vestíbulo-lingual (feminino: 9,28-9,54; masculino: 9,56-9,88).Rio de Janeiro Dental Journal2019-05-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://cro-rj.org.br/revcientifica/index.php/revista/article/view/9310.29327/24816.4.1-12Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal); Vol. 4 No. 1: January-April 2019; 73-78Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal); v. 4 n. 1: January-April 2019; 73-782595-47331518-524910.29327/24816.4.1reponame:Revista Científica do CRO-RJ (Online)instname:Conselho Regional de Odontologia do Rio de Janeiro (CRO-RJ)instacron:CROporhttps://cro-rj.org.br/revcientifica/index.php/revista/article/view/93/56Copyright (c) 2019 Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal)info:eu-repo/semantics/openAccessAndrade, Rodrigo da SilvaFernandes, Larissa Chaves CardosoBento, Maria Izabel Cardosode Lima, Kenio CostaRabello, Patrícia MoreiraSantiago, Bianca Marques2019-12-03T13:37:08Zoai:ojs3.cro-rj.org.br:article/93Revistahttps://cro-rj.org.br/revcientifica/index.php/revistahttps://cro-rj.org.br/revcientifica/index.php/revista/oairevista.cientifica@cro-rj.org.br || rorefa@terra.com.br2595-47331518-5249opendoar:2019-12-03T13:37:08Revista Científica do CRO-RJ (Online) - Conselho Regional de Odontologia do Rio de Janeiro (CRO-RJ)false |
