Prevalencia de erupción pasiva alterada en los alumnos de odontología de la UCSG.

Abstract

Introduction: The dental eruption is a physiological process that is divided into two phases: active and passive. An alteration in the passive phase will result in an altered passive eruption (EPA), which would be defined as the interruption of the apical migration of the margin of the gingiva, where it moves away from the amelocementary limit. This can be classified into 2 groups and 2 subgroups: 1A, 1B, 2A and 2B. Its importance lies in its diagnosis and treatment, since it is responsible for a large part of the consultations for restorative treatments due to the alterations that can produce in the aesthetics of the smile due to its clinical signs: short teeth, absence of gingival scallopings, and gingival smile. Materials and Methods: A cross-sectional descriptive and analytical study where 100 UCSG odontology students were randomly selected according to the inclusion and exclusion criteria. The prevalence of altered passive eruption and its types was determined by the T Bar, a periodontal probe and periapical radiographs. Results: 100 subjects, 35 men and 65 women were analyzed. 16% of the subjects had EPA, of which 19% 1A and 81% 1B. The prevalence of high smile in people with short teeth was 37.5% and 31.25% in middle and low smiles. The variables of ethnicity and genetics were irrelevant. Conclusion: The EPA had a low prevalence of 16%, being more prevalent in women. I had no direct relation to the type of smile.
