PERIODONTAL HEALTH STATUS OF FIXED SELF–CURE DENTURE ABUTMENTS
This analytical cross sectional study was conducted at the Prosthodontics and Periodontology Department of Islamabad Dental Hospital, over a period of one year from July 2015 to June 2016. The aims of study were to document chief complaints of patients at the time of their visit to Islamabad Dental hospital, reasons to visit unqualified dentists, evaluate complications of fixed self-cure dentures in short and long term wearers and compare bone loss of abutment and adjacent teeth. Thirty systemically healthy patients reporting to the department with complaints regarding previously received FSD were included in the study.
After written consent, patients filled questionnaire and were clinically & radiographically examined by a researcher following denture removal. Most common chief complaint was pain 15(50%), and lack of awareness was the major reason for receiving FSD 24(80%). In long term wearers deep pockets (>6mm) were present in 19 abutments while in short term wearers only one abutment had deep pocket. In short term wearers mobility was recorded in 7(36.8%) abutments whereas in long term wearers mobility was recorded in 51(92.7%) abutments. The bone loss in abutments was significantly more as compared to the adjacent teeth (p-value=0.04). Abutment tooth loss was observed in 10(33.3%) patients at the time of denture removal and a total of 19(25.6%) with poor prognosis were advised extractions.
In conclusion, dentures fixed with self-cure acrylic resin have harmful effects that lead to periodontal pocket formation, bone loss or abutment tooth loss especially with long term use of these dentures.
