Resumo: | Objective: This study aimed to compare through cone-beam computed tomography (CBCT) the morphology of the cervical vertebrae atlas (C1) and axis (C2) in mouth breathers (MB) and nose breathers (NB), correlating them with the head and neck postures of the two groups. Materials and Methods: CBCT imagesof 36 subjects aged 11 to 22 years were evaluated using the InVivo Dental 5.1 (Anatomage, San Jose, California) software. The following measurements were used to assess C1 and C2 morphology: posterior height, anterior height, length, and volume. The craniocervical angle (NSL/OPT) was used to evaluate headposture concerning the neck. Results: The posterior height, length, and volume of C1 and C2 were lower in the MB group, but only the posterior size was significantly shorter than the NB group (C1, p=0.01 / C2, =0.05). Mouth breathers also showed a considerably higher craniocervical angle (p=0.04). Spearman test showed asignificant positive correlation between C1 and C2 length and craniocervical angle (C1, =0.629, p=0.005 / C2, =0.665, p=0.003). Conclusion: The mouth breathers showed an increased craniocervical angle and decreased posterior height of the C1 vertebra concerning nasal breathers. The hyperextension of the head present is positively correlated with the length of the vertebra. |

Materiais e Métodos: Imagens de TCFC de 36 indivíduos de 11 a 22 anos foramavaliadas utilizando-se o software InVivo Dental 5.1 (Anatomage, San Jose, Califórnia). Foram utilizadas as seguintes medidas para avaliar a morfologia de C1 e C2: altura posterior, altura anterior, comprimento e volume. O ângulo craniocervical (NSL/OPT) foi utilizado para avaliar a postura da cabeça em relação ao pescoço. Resultados: A altura posterior, o comprimento e o volume de C1 e C2 foram menores no grupo RB, mas apenas a altura posterior foi significativamente menor em comparação com o grupo RN (C1, p=0,01 / C2, p=0,05). Os respiradores bucais também apresentaram ângulo craniocervical significativamente maior (p=0,04). O teste de Spearman mostrou correlação positiva significativa entre o comprimento de C1 e C2 e o ângulo craniocervical (C1, p=0,629, p=0,005 / C2, p=0,665, p=0,003). Conclusão: Os respiradores bucais apresentaram aumento do ângulo craniocervical e diminuição da altura posterior da vértebra C1 em relação aos respiradores nasais. A hiperextensão da cabeça presente está positivamente correlacionada com o comprimento da vértebra.Rio de Janeiro Dental Journal2021-04-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://cro-rj.org.br/revcientifica/index.php/revista/article/view/22110.29327/244963.6.1-5Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal); Vol. 6 No. 1: January-Abril 2021; 26-33Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal); v. 6 n. 1: January-Abril 2021; 26-332595-47331518-524910.29327/244963.6.1reponame: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/221/128Copyright (c) 2021 Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal)info:eu-repo/semantics/openAccessda Costa, Carolina MessiasCosta, Julia GarciaSaramago, Adriana de Alcantara CuryMattos, Claudia TrindadeVilella, Beatriz SouzaVilella, Oswaldo de Vasconcellos2021-12-17T21:10:53Zoai:ojs3.cro-rj.org.br:article/221Revistahttps://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:2021-12-17T21:10:53Revista Científica do CRO-RJ (Online) - Conselho Regional de Odontologia do Rio de Janeiro (CRO-RJ)false |
