Relationship between intrinsic and extrinsic factors with Erosive Tooth Wear in adults: a cross-sectional study

Abstract The objective of this study was to explore the relationship between intrinsic and extrinsic factors and a high cumulative score of the Basic Erosive Wear Examination (BEWE) in a Chilean adult group. A cross-sectional study was performed with the Ethics Committee's approval from the Universidad de los Andes. A consecutive adult (18 to 46 years old) sampling (n = 553) from the Health Center in San Bernardo-Chile, was selected from September 2016 to January 2017. Dental exams were performed by two trained and calibrated examiners, according to the BEWE index. In order to search for potentially related factors, a hetero-applied questionnaire previously developed and evaluated was applied. Our interest was individuals with severe erosion tooth wear (BEWE ≥ 14). Logistic regression models reporting crude odds ratio (OR) and adjusted OR by age, 95% confidence interval (95%CI), and p-values were estimated. Variables, odds ratios and 95% CI related with BEWE ≥ 14 were: age (OR 1.1 [1.07-1.14]); currently drinking alcohol (OR 1.59 [1.06-2.39]); esophagitis (OR 8.22 [1.60-42.22]); difficulty to swallow (OR 2.45 [1.10-5.44]); chest pain (OR 2.07 [1.18-3.64]); anorexia (OR 3.82 [1.07-13.68]); vitamin C intake (OR 1.92 [1.08-3.43]). Age, alcohol consumption, self-reported esophagitis, history of gastric symptoms, anorexia, and vitamin C intake were related as risk factors to high BEWE scores in this sample of Chilean adults in San Bernardo, Chile.

Contenidos de cariología impartidos por escuelas dentales chilenas: Estudio transversal / Contents of cariology taught by Chilean dental schools: Cross-sectional study

RESUMEN: Objetivo: determinar los contenidos impartidos en cariología, su aplicación clínica y metodología educativa empleada, en las escuelas dentales chilenas de pregrado. Método: Se efectuó un estudio de corte transversal, en una muestra por conveniencia de docentes de cariología y/o asignaturas relacionadas con cariología en 23 de 29 escuelas de odontología chilenas (año 2015), n=13 acreditadas ante la Comisión Nacional de Acreditación y n=10 de 16 no acreditadas. Se envió un cuestionario de 55 preguntas por vía electrónica, basado en los dominios propuestos por la Asociación para la Educación Dental Europea. El cuestionario fue sometido al análisis y evaluación previa de contenido y lenguaje por un comité de expertos, los resultados fueron tabulados y analizados utilizando STATA v14.2. Resultados: La tasa de respuesta del cuestionario fue de 86,95%. En promedio el 70% de los contenidos encuestados son impartidos, de ellos, el 65% se impartieron en clases teóricas, el 14% en práctica de laboratorio y se realizó aplicación clínica en el 24% de los contenidos impartidos. Conclusiones: La actual enseñanza de la cariología en las escuelas dentales chilenas es alta en contenidos teóricos, los que mayoritariamente no se imparten a través de práctica de laboratorio y la aplicación clínica de los contenidos desarrollados es escasa.

ABSTRACT: The objective: was to determine the current contents of cariology taught, its clinical application and educational methodology used in Chilean undergraduate dental schools. Materials and Method: A cross-sectional study was carried out in a convenience sample of cariology teachers and/or teachers of cariology-related subjects belonging to 23 of the 29 Chilean Dental Schools (year 2015), including n=13 out of 13 schools accredited by the National Accreditation Commission, and n=10 out of 16 non-accredited schools. A questionnaire of 55 questions was sent electronically, based on the domains proposed by the Association for European Dental Education (ADEE). The survey was subjected to prior analysis and evaluation of content and language by a panel of experts, the results were tabulated and analyzed using STATA v14.2. Results: The response rate o was 86.95%. On average, 70% of the contents surveyed are taught, of which 65% were taught in didactic classes, 14% were in laboratory practice and 24% were taught in the clinical setting. Conclusions: The current teaching of cariology in chilean dental schools includes a large number of subjects taught mainly in didactic settings, with less in the laboratory practice, while the clinical application of the contents developed is scarce.
