Summary
Many dentists lack proper protocols for processing polishing points, essential for microbiological control in composite resin restorations. Despite reporting good knowledge, over half use inadequate methods, highlighting a critical gap in dental instrument reprocessing.
Area of Science:
- Dental instrument reprocessing
- Microbiological control in dentistry
- Composite resin restoration polishing
Background:
- Polishing points are semi-critical instruments widely used in esthetic dental restorations.
- Inadequate processing of polishing points poses risks for microbiological control.
- No specific protocol exists to guide dentists in processing these instruments.
Purpose of the Study:
- To assess dentists' knowledge and practices regarding the processing of polishing points.
- To identify factors associated with inadequate processing of dental instruments.
Main Methods:
- Cross-sectional observational study utilizing an online questionnaire.
- Data collected via Google Forms and social media promotion.
- Statistical analysis included logistic and Poisson regressions.
Main Results:
- 473 questionnaires were analyzed, with 51% of dentists reporting inadequate processing methods.
- Nearly 68% of professionals claimed good knowledge of instrument processing.
- Increased age and time since graduation were associated with adequate processing practices.
Conclusions:
- A significant number of dentists employ improper methods for processing polishing points.
- A discrepancy exists between dentists' reported knowledge and actual practices in instrument reprocessing.
- Addressing this knowledge-practice gap is crucial for enhancing patient safety in restorative dentistry.
