Study Notes
- Rubber dam isolation protects the patient and dental team from contamination and aerosols
- There are two types of rubber dam: latex and non-latex, and four thicknesses: light, medium, heavy, and extra heavy
- Medium thickness rubber dam is recommended for better fit and retraction
- Rubber dam retainers include metal and plastic clamps, each with advantages and disadvantages
- Different styles and shapes of clamps are available for specific situations
- Teeth needing root canal treatment may require additional procedures for good isolation
- Ligation, deep-reaching clamps, and clamping the gingiva are methods to isolate teeth with inadequate coronal structure
- Temporary restorations can be used when there is not enough tooth structure but adequate retention
- Reinforced intermediate restorative material (IRM) is used for temporary restorations and provides a good coronal seal
- Bonded materials provide a better seal, strength, and esthetics than IRM but are more time-consuming to place.
