Avaliação do conhecimento dos estudantes de odontologia sobre o diagnóstico e plano de tratamento da cárie na superfície oclusal pigmentada

Abstract

Objective: Assess the knowledge of dental students about the diagnosis and treatment of occlusal lesions with pigmented fissure. Materials and Methods: The research was a scientific study in vitro, observational, transversal, descriptive, quantitative, with an inductive approach. The sample was represented by 93 students of the Dentistry course at private university of Paraíba. The gathering‟s instruments were a model of plaster with five posterior teeth with pigmented fissure, included, and a quiz. In the analysis of the data, a comparison was made with the highest frequency of each aspect of the fissure, found in the results obtained from the histological sections of a previous study, with 83 sites of pigmented fissures, using the same description (gold standard). Descriptive statistics techniques were used, through absolute percentage distributions. Results: Considering the aspect of the scores: pigmented fissure restricted to the interior of the fissure; slight widening of the pattern of cleft pigmentation; widening of the fissure pigmentation pattern; pigmented fissure associated with localized discoloration of the enamel, without visible dentin; with the dark shadow hidden in dentin, compared to the spots, it was found that: 74.2%, 73.2%, 50.5%, 47.3% and 34.3% of the students matched the standard gold. Conclusion: The diagnosis of occlusal lesions associated with pigmented fissures is still divergent and complex for dentistry students. The difficulty is greater in the determination of lesions in dentin, under apparently intact enamel. Students need to take a more conservative approach, aligned with Minimally Invasive Dentistry, especially for the treatment of enamel lesions.
