The correct procedure that provides a sterile environment during dental operations is the use of a dental (rubber) dam. A dental dam is a thin sheet of latex or non-latex material that isolates the teeth being treated from the rest of the mouth. This isolation helps to keep the area dry and free from saliva, which is crucial during certain dental procedures to maintain a sterile field. The dental dam reduces the risk of contamination from bacteria and other pathogens present in the saliva, thus enhancing the effectiveness of the treatment and ensuring patient safety.

In contrast, apexification and pulp capping are dental procedures aimed at addressing issues related to the tooth's pulp and root structure, rather than focusing on maintaining a sterile environment during treatment. Voice control is a behavioral management technique used to help patients feel more comfortable during dental procedures but does not contribute to sterility.
