Objetivo: Este estudo teve como objetivo determinar a prevalência da centralidade da linha média dentária em relação à linha média facial do sorriso em dentição natural, em pacientes com idades entre 18 e 30 anos, atendidos nas Clínicas de Prática Médico-Dentária (CPMD) da Faculdade de Ciências da Saúde da Universidade Fernando Pessoa (FCS-UFP).
Metodologia: Trata-se de um estudo observacional, descritivo e transversal, aprovado pela Comissão de Ética da Universidade Fernando Pessoa (UFP). A análise centrou-se na observação da simetria do sorriso — definida pela coincidência ou não da linha média dentária com a linha média facial. Os dados foram recolhidos a partir de fotografias extraorais, analisadas com recurso ao software PowerPoint® 2010. A análise estatística foi realizada através do software IBM® SPSS® Statistics vs. 30.0, utilizando testes descritivos e inferenciais, maioritariamente não paramétricos, considerando um nível de significância de α = 0,05.
Resultados: Cerca de metade dos indivíduos (49,2 % (IC95%: 40,4% – 57,8%)) apresentavam uma linha média centrada. A não coincidência da linha média dentária superior com a linha média facial foi a característica mais prevalente na amostra total (50,8 %), com predominância de desvio para o lado direito (37,5 %). A prevalência de indivíduos cuja linha média dentária se encontrava centrada em relação à linha média facial foi de 49,2 %. A análise cruzada revelou que os indivíduos do sexo masculino apresentaram uma maior frequência de desvios, particularmente para o lado direito, com uma associação linear estatisticamente significativa (p = 0,035). Não foi encontrada associação estatisticamente significativa entre a nacionalidade e a centralidade da linha média dentária.
Conclusões: A maioria dos indivíduos avaliados apresentou desvios leves da linha média dentária, frequentemente para o lado direito, situando-se dentro de limites estéticos considerados aceitáveis. Desvios até 2 mm continuam a ser considerados clinicamente toleráveis para o planeamento ortodôntico e a reabilitação oral.
Objective: This study aimed to determine the prevalence of dental midline centrality in relation to the facial midline of the smile in individuals with natural dentition, aged between 18 and 30 years, who were treated at the Clinical Practice in Dental Medicine (CPMD) of the Faculty of Health Sciences at Fernando Pessoa University (FCS-UFP). Methodology: This is an observational, descriptive, and cross-sectional study, approved by the Ethics Committee of Fernando Pessoa University (UFP). The analysis focused on the observation of smile symmetry — defined by the coincidence or not of the dental midline with the facial midline. Data were collected from extraoral photographs and analyzed using PowerPoint® 2010. Statistical analysis was performed using IBM® SPSS® Statistics vs. 30.0, with descriptive and inferential tests, mostly non-parametric, considering a significance level of α = 0.05. Results: Non-coincidence of the upper dental midline with the facial midline was the most prevalent characteristic in the total sample (50.8%), with a predominance of deviation to the right side (37.5%). The prevalence of individuals whose dental midline was centered in relation to the facial midline was 49.2%. Cross-tabulation analysis revealed that male individuals showed a higher frequency of deviations, particularly to the right side, with a statistically significant linear association (p = 0.035). No statistically significant association was found between nationality and dental midline centrality. Conclusions: Most individuals evaluated presented slight deviations of the dental midline, most frequently to the right side, within aesthetic limits considered acceptable. Deviations of up to 2 mm are still regarded as clinically tolerable for orthodontic planning and oral rehabilitation.
