Dental OSCE (Objective Structured Clinical Examination) Practice Exam

The proxy brush is considered the best method for cleaning a fixed partial denture (FPD) because it is specifically designed to reach the interproximal and difficult-to-access areas around the connectors and pontics of the FPD. Its unique shape allows for effective cleaning of the margins where plaque and food debris tend to accumulate, which can help maintain the health of the surrounding periodontal tissues and prevent decay or inflammation.

In contrast, while a toothbrush is essential for cleaning the natural teeth and the external surfaces of the FPD, it may not effectively reach the spaces between the teeth and the prosthetic. Dental floss, although useful for cleaning between teeth, may not adequately clean areas around the pontics, making it less effective for FPD care. A water flosser can help reduce plaque and rinse away particulates but may not provide the focused scrubbing action that a proxy brush does in promoting thorough cleaning and maintaining the longevity of the prosthesis. Therefore, a proxy brush is the ideal tool for optimal hygiene around fixed partial dentures.
