Actitudes de odontólogos peruanos sobre el aislamiento absoluto. Diseño y validación de una escala en tiempos de COVID-19

Introduction: Rubber dam isolation is a dental procedu-re that ensures biosafety and the quality of restorative treatments; however, no appropriate tool is available to evaluate the topic in Peruvian reality. Objective: Design and validate a scale to evaluate the attitude of Peruvian dentists toward rubber dam isolation. Methods: An instrumental cross-sectional study was con-ducted. The scale was applied through a virtual questionnaire and then distributed on social networks to 279 dentists (143 women and 136 men) selected by intentional nonprobability sampling. Age ranged from 22 to 67 years. Results: Aiken’s V coefficient values were favorable for all items. Exploratory factor analysis showed the presence of a single factor. Confirmatory factor analysis suggested deletion of items 1 and 7. Reliability of the scale proved to be good. It was estimated with a Cronbach’s α coefficient of 0.71. Conclusions: The scale about attitudes of Peruvian dentists toward rubber dam isolation (Act-AA-Cov19) is a brief, valid and reliable measurement which may be used for research purposes.
