Background: Removable partial dentures (RPD) have an important role in the health of periodontium. Some patients are unable to afford treatment with implants either anatomical or economic reasons, therefore RPD can be considered a simple, noninvasive, and relatively cheap treatment option for the shortened dental arch. Aim of the study: To study periodontal health of Abutment teeth supporting Removable Partial dentures. Materials and methods: The present study was conducted by joint effort of Department of Prosthodontics and Department of Pedodontics of the Dental institution. For the study, we selected patients that received RPD from the institute clinic. They were contacted and invited to participate in the study. The duration for which the patient was wearing the removable denture following placement varied from 1 year to 7 years. For the reduction of observational error, the task of measurements was given to a single examiner. A total of 50 patients participated in the study. A written consent was obtained from the participants after explaining to them the procedure and advantages of study. The design of the denture and classification for ridge according to Kennedy’s classification (from Class I to Class IV) were recorded and noted for further evaluation. Results: A total of 50 patients participated in the present study. 42 patients were male and 28 patients were females. The number of removable Partial dentures examined was 70 RPDs. Based on the design of RPD, 51 RPDs were clasp retained and 19 RPDs were with attachments. We observed that Grade 0 mobility was present in majority of abutment teeth (n=42), out of which 28 teeth were with clasp retained RPDs and 14 teeth were with attachments. Grade 1 mobility was present in 18 patients, 14 were clasp retained and 4 were with attachments. Grade 2, 3 and 4 mobility was absent in patients with attachment RPDs. Conclusion: From the results of present study, we conclude that the periodontal health of clasp retained abutment teeth is more compromised as compared to attachment RPDs.
