It is widely used, as it is economical and acceptable modality of treatment. An improper design of removable partial denture will result in the accumulation of food debris and plaque on teeth and gingival margins and can compromise periodontal support. Aim To assess the periodontal health of the primary abutment teeth supporting temporary partial denture prostheses. Methodology Twentypatients who have been wearing removable partial denture reported to Saveetha Dental College, aged 32–72 years for review were included in the study. Patients wearing temporary partial dentures for more than 2 years, both the genders, patients who are willing to participate the study were the included in the study. Patients wearing over dentures, fixed removable prosthesis and patient wearing removable prosthesis for maxillofacial defects were excluded from the study. The primary abutments supporting the temporary partial dentures with retainers were assessed for periodontal status by estimating loss of attachment (LOA) and gingival recession. Loss of attachment (LOA) and gingival recession was measured using Williams probe and read to nearest millimetres (mm) at four areas (mesiobuccal, distobuccal, mesiolingual, distolingual) for each tooth. Result The mean value of loss of attachment of abutment teeth was found to be 1.98+0.28mm and non-abutment tooth was 1.58+0.34 mm and statistically significant difference was observed between the primary and control abutments (T value =5.55, P value < 0.001)(Table 1), while the mean value of gingival recession of abutment teeth and nonabutment teeth was found to be 1.69+0.47 mm and 1.16+0.24 mm respectively and statistically significant difference was observed between the primary and control abutments (T value =4.67, P value < 0.001) (Table 2). Conclusion The patients receiving removable partial denture should be carefully motivated, educated and instructed to prevent periodontal diseases. With carefully designed prosthetic treatment and adequate maintenance of oral hygiene, little or no damage will be caused to remaining teeth and their periodontal support. Periodic recall for review of dentures helps to avoid compromises in oral health. Top Keywords Removable partial denture, Periodontal status, Gingival index, Loss of attachment, Gingival recession.
