ABSTRACT: Aim: To describe the current state of undergraduate Cariology teaching in Chilean universities. Material and Methods: A previously content-validated questionnaire was used to conduct a cross-sectional study including all private/public universities. Statistical analysis was performed determining frecuency distributions of categorical variables with the Stata Data Analysis and Statistical Software 13.1®. Results: Cariology is a key issue in undergraduate education, and in most universities, is taught as key axis of courses, in various departments, for more than one year. Consistency was found in Cariology topics taught. The clinical threshold for surgical treatment is roughly divided into thirds (33.3% enamel microcavitation, 38.9% underlying shadow and 27.8% dentin cavity), no university indicated operative treatment for non cavitated lesions. Radiographic threshold for surgical treatment is the external dentinal third (66.7%). Conclusions: Answers revealed a mix of traditional and modern Cariology concepts. Depite some encouraging results, half of Chilean universities considered that Cariology is not appropriately implemented and no standardization exists between theoretical teaching and clinical management, nonoperative management is not properly clinically implemented, students are evaluated for tissue damage restoration and resistance to non-invasive philosophy adoption remains.
