PREVALENCE OF DENTAL AND PERIODONTAL STATUS AND ASSOCIATION WITH LENGTH OF TIME SINCE BEGINNING DIALYSIS

2016 
Objective: Among all the systemic disorders, diseases of the renal system pose a major cause of morbidity and mortality worldwide. The present study aims to establish the multivariate relationship of socio demographic conditions, state of dental health, periodontal health among patients in relation to duration of hemodialysis (HD). Method: A cross-sectional study, using a self-administrated structured questionnaire was conducted among haemodialysis patients. A self-structured questionnaire in English language was designed to record the patient’s sociodemographic data, duration of dialysis, smoking habit and tooth cleaning habits, medication history and other medical condition. Dental and periodontal status was also recorded. Results: A total of 133 patients were registered for the study. Of these patients, the one undergoing haemodialysis for less than 1 years were 53 whereas the one undergoing HD for 1-3 years and for more than 3 years were 47 and 33 respectively. The difference in mean values of the periodontal indices when compared among three groups were statistically significant. A higher prevalence of decayed teeth (p<0.001) and larger DMFT index (p<0.01) was found to be significantly correlated with duration of haemodialysis. Conclusion: Within the limits of this study, it was concluded that subjects who were being treated with HD for more than 3 years had a poorer periodontal health and a higher DMFT index score, suggesting that the length of time on HD could negatively affect the oral health status of these individuals.
