Correct answer: B — To isolate the tooth from saliva and bacterial contamination and prevent aspiration/ingestion of instruments and irrigants
Dental dam (rubber dam) isolation is the standard of care during endodontic treatment. Its primary functions are: (1) preventing salivary and bacterial contamination of the root canal system; (2) preventing aspiration or swallowing of endodontic instruments, irrigants (NaOCl), and debris; (3) improving visibility and access; and (4) retracting soft tissues. Failure to use a dental dam during endodontic treatment is considered below the standard of care in most jurisdictions.
