Análisis de los patrones de la sonrisa y su relación con el grosor de los labios en los estudiantes de la clínica odontológica UCSG A 2023.

Abstract

Introduction: Smile analysis is important before starting a dental treatment. Tissue evaluation, for a long time left aside, is part of the diagnosis and planning process for proper treatment. Objective: Relate smile patterns and lip thickness. Methods. Descriptive and transversal study. The sample was composed of 100 eleventh and ninth students (50 women and 50 men) of the dental career of the Santiago Catholic University of Guayaquil, aged between 18 and 35. Two photographs were taken, one frontal in rest and one smiling. For the measurements of the thickness of the lips, the Digital Image program in rest photography was used. Each of the smile patterns was identified, which were divided into style, type and stage of smile, in the smile photograph. Results: Statistically significant relationship was found between the thickness of the lower bermellon and the type of smile (p<0,001). The most common smile patterns were comissural (69.9%), type I (48.5%) and stage III (97%). Conclusion: Significant relationship was found between the thickness of the lower bermellon and the type of smile.
