Abstract(s)
Objetivos: O objetivo deste estudo foi determinar a prevalência de desvio da linha média facial e inclinação da linha média dentária do sorriso na dentição natural em pacientes frequentadores das CPMD – (FCS - UFP) com idade compreendidas entre 18 e 30 anos. Metodologia: Estudo descritivo observacional transversal, aprovado pela Comissão de Ética da UFP. Observação de características do sorriso estético: simetria (centralidade ou falta de centralidade da linha média dentária com a linha média facial) e a inclinação, em fotografias extraorais, e através do software PowerPoint (2010)®. Análise descritiva/inferencial (maioritariamente não-paramétrico) com IBM©SPSS®Statistics vs. 29 (α= 0,05). Resultados: A falta de coincidência da linha média dentária superior com a linha média facial mostrou ser a mais prevalente na amostra total (60,6 %) juntamente com a presença de inclinação (89,4 %), com predomínio de desvio para direita (33,7 %) não superando 3,5° de inclinação (média de 2,32°). A prevalência dos individuos com a linha média dentária centrada com a linha média facial resultou no intervalo de 30,0 % - 49,5 % da amostra total. Conclusões: Verificou-se que a maioria dos indivíduos apresentava um leve desvio da linha média dentária, principalmente para o lado direito. No entanto, esses desvios estavam dentro de limites estéticos aceitáveis, por volta de 1mm e a inclinação média foi de 2,32°. Não foi encontrada uma associação significativa entre o desvio da linha média dentária e a inclinação em relação ao gênero. Em geral, um desvio da linha média dentária de até 2 mm, com uma inclinação máxima de 3,5º - 4°, é considerado aceitável para o planejamento do tratamento ortodôntico e reabilitação oral.
Objective: The goal of this study was to determine the prevalence of facial midline deviation and midline smile inclination in natural dentition in patients attending the CPMD - (FCS - UFP) aged between 18 and 30 years. Methods: A cross-sectional observational descriptive study, approved by the UFP Ethics Committee. Observation of characteristics of the aesthetic smile: symmetry (centrality or lack of centrality of the dental midline with the facial midline) and the inclination, in extraoral photographs, and through the PowerPoint (2010) ® software. Descriptive/inferential analysis (mostly non-parametric) with IBM© SPSS® Statistics vs. 29 (α= 0.05). Results: The lack of coincidence of the upper dental midline with the facial midline proved to be the most prevalent in the total sample (60.6 %) along with the presence of inclination (89.4 %) with a predominance of deviation to the right (33.7 %) not exceeding 3.5° of inclination (mean 2.32°). The prevalence of individuals with dental midline centered with facial midline resulted in the range of 30.0 % - 49.5 % of the total sample. Conclusions: It was found that most individuals had a slight deviation of the dental midline, especially to the right side. However, these deviations were within acceptable aesthetic limits, around 1 mm and the average inclination was 2,32°. No significant association was found between dental midline deviation and gender bias. In general, a deviation of the dental midline of up to 2 mm, with a maximum slope of 3,5º - 4º, is considered acceptable for the planning of orthodontic treatment and oral rehabilitation.
