, Hugo Gaêta-Araujo 3, Larissa de Oliveira Reis 1, Deivi Cascante-Sequeira 1, Danieli Moura Brasil 1, Christiano Oliveira-Santos 4, Deborah Queiroz Freitas 1Highlights |
• | Sex has little influence on the angulation incisors and nasopalatine canal. |
• | Class II dolichofacial women and men have sex inclination between incisors and nasopalatine canal. |
• | Class III dolichofacial men have greater inclination between incisors and the nasopalatine canal. |
Summary |
Objectives |
To assess the influence of sagittal and vertical skeletal patterns, and sex in the angulation and relationship between the maxillary central incisors and the nasopalatine canal.
Materials and methods |
Cone-beam computed tomography (CBCT) exams of 172 patients were classified into sagittal (class I, II, and III) and vertical skeletal patterns (mesofacial, brachyfacial and dolichofacial). Hard palate-nasopalatine canal and hard palate-long axis of maxillary central incisors angles were measured in sagittal reconstructions. The obtained angles were used to calculate the angulation between maxillary central incisors and nasopalatine canal by triangle geometric relationship. Analysis of variance (multi-way ANOVA) and Tukey post-hoc test were used for data analysis (α=5%).
Results |
Sagittal and vertical skeletal patterns, and sex presented a low influence on the angulation of maxillary central incisors and nasopalatine canal. Dolichofacial class II women showed the greatest hard palate-nasopalatine canal angulations (P<0.05) and maxillary central incisors and nasopalatine canal angulations (P<0.05). Mesofacial class II and III men presented the lowest maxillary central incisors and nasopalatine canal angulations (P<0.05).
Conclusions |
The sagittal and vertical skeletal patterns, and sex have a low influence on the angulation of the maxillary central incisors and the nasopalatine canal.
