Diagnóstico y tratamiento de lesiones físicas-químicas dentarias : nivel de conocimiento en estudiantes de odontología.

Abstract

OBJECTIVE: To determine the level of theoretical-clinical and therapeutic knowledge regarding the physical-chemical lesions of the dental structure (abrasion, abfraction, attrition, and erosion) among Dentistry students at the Catholic University of Santiago de Guayaquil during the B-2025 academic period. MATERIALS AND METHODS: A quantitative, cross-sectional, observational, and analytical study was conducted with 259 students enrolled in the B-2025 period. A questionnaire consisting of 15 questions divided into two sections was used: theoretical-clinical knowledge (9 items) and therapeutic knowledge (6 items). Each correct answer received one point, resulting in an overall score classified as high (15-11), moderate (10-7), and low (6-0). The data were analyzed using descriptive statistics and Fisher's exact test to evaluate the association between knowledge level and academic year. RESULTS: It was found that 71% of the students demonstrated a high level of knowledge, while 7.7% showed a low level. The majority correctly identified erosion (81.47%), attrition (86.10%), abfraction (74.90%), and abrasion (70.27%), as well as their etiological factors. Regarding treatment, 66.02% recognized the appropriate approach based on etiological control and restoration when necessary. CONCLUSION: The students demonstrated a high level of knowledge, especially in advanced cycles, such as tenth grade.
