Lesson content
The use of a rubber dam system greatly facilitates dental treatment and increases its efficiency. The installation of the rubber dam system should not take more than 3–5 minutes. If circumstances do not permit the installation of a rubber dam system, alternative methods of isolation should be considered.
There are 2 methods of isolation: relative and absolute, the names of which reflect the degree of waterproofing of the working field.
Relative method involves the use of cotton rolls, retraction threads, various aspiration devices, retraction instruments, etc. Absolute — application of the rubber dam or optidam system (OptiDam).
