Final answer:
To provide a tight seal around the teeth and prevent saliva from leaking while using a rubber dam, the dental assistant should follow specific steps. These include stretching and preparing the rubber dam, placing the clamp, securing the dam, and inspecting for gaps. This creates a clear working area for the dentist.
Step-by-step explanation:
To provide a tight seal around the teeth and prevent saliva from leaking while using a rubber dam, the dental assistant should follow these steps:
- Ensure that the rubber dam is properly stretched and prepared for use.
- Place the rubber dam clamp on the tooth or teeth being isolated.
- Secure the rubber dam using dental floss or ligature ties.
- Inspect the seal to ensure there are no gaps or leaks. If necessary, adjust the position of the rubber dam or re-tighten the floss/ties.
By following these steps, the dental assistant can create an effective barrier that prevents saliva from leaking and provides a clear working area for the dentist.
