Quantitative changes in dental plaque formation related to removable partial dentures

Abstract

Plaque formation on forty-four teeth acting as abutments for removable partial dentures was studied while the patients were wearing their dentures and while they were not. The amount of plaque was assessed according to Quigley & Hein (1962), modified by Kardel & Bay (1967). In addition, that formed occlusally was evaluated by an occlusal plaque scoring index designed for the present study. It was found that the wearing of partial dentures increased the formation of plaque on all tooth surfaces under investigation.
