Plaque-retentive factors
Plaque-retentive factors
Local plaque-retentive factors, such as calculus, mal-positioned teeth, overhanging restorations, crown and bridgework, partial dentures and fixed and removable orthodontic appliances can complicate or hinder plaque biofilm removal in the area, increase the risk of gingival and periodontal inflammation and are a risk factor for disease (see figure: Local plaque retentive factors). Where supragingival calculus deposits are present, removal of these may be necessary for effective personal oral hygiene to be achieved.

Explain to patients with local factors such as crowded teeth, partial dentures, bridgework and orthodontic appliances, the importance of plaque biofilm removal in these areas.
Ensure that fixed and removable prostheses and appliances are well-designed and that they are a good fit.
Give specific instruction on how to clean adequately around fixed and removable prostheses and fixed appliances.
Remove calculus, modify overhanging or poorly contoured restorations or replace the restoration where it impedes effective oral hygiene.
