Surgical Isolation with Rubber Dam - CDT Code Guide

Endodontics/Other Endodontic Procedures

Overview

CDT code D3910 refers to the surgical procedure for isolating a tooth using a rubber dam. This procedure is an essential part of endodontic treatments, ensuring that the tooth is kept dry and free from contamination during surgical interventions. The rubber dam acts as a barrier, isolating the tooth from saliva and other oral fluids, which is crucial for maintaining a sterile environment. Typically, this procedure is used in complex endodontic cases where precision and cleanliness are paramount, such as during root canal therapy or other intricate dental surgeries. By isolating the tooth, the dentist can work more efficiently and effectively, reducing the risk of infection and improving the overall outcome of the procedure.

When to Use This Code

During root canal therapy to maintain a sterile environment.
When performing apicoectomy to prevent contamination.
In cases of complex endodontic surgeries requiring isolation.
When treating teeth with extensive decay or damage.
To ensure a dry field for adhesive dental procedures.

Documentation Requirements

Detailed clinical notes describing the need for isolation.
Pre-operative and post-operative photographs if applicable.
Patient consent forms acknowledging the procedure.
Specific tooth number(s) involved in the procedure.
