Knowledge and practice of dentists in processing polishing points: A cross-sectional study

Background Adequately processing polishing points used to polish composite resin restorations is necessary for microbiological control in dentistry, but there is no specific protocol to guide professionals. Therefore, this study aimed to assess the knowledge and practice of dentists in processing these instruments. Methods This cross-sectional observational study included the application of an online questionnaire via Google Forms and social media promotion. The study evaluated the association of field of activity, time since graduation, age, and sex of professionals with processing practice. The statistical analysis was performed with absolute and relative frequencies and logistic and Poisson regressions at a 5% significance level. Results Overall, 473 questionnaires were analyzed. A rate of 51% of professionals reported using inadequate processing methods, and almost 68% claimed to have good knowledge of the topic. Both regression analyses were significantly associated, showing a direct effect of age and time since graduation on adequate processing practices. Conclusions Although most professionals reported understanding the processing of polishing points, they do not perform it most adequately. Clinical Significance An expressive number of dentists process polishing points improperly. The topic is significant for representing a semi-critical instrument extensively used in esthetic restorations.
