Oral health related quality of life in patients with diabetes mellitus type 2 in the year 2012

BACKGROUND AND AIM: The aim of this study was investigation of oral and dental side effects of diabetes mellitus (DM) on oral health-related quality of life (OHQoL) in patients with DM type 2.METHODS: In this descriptive, analytic study 121 patients were participated by consecutive method based on the type of diabetes and the age. After the subjects received adequate explanations about the necessity of carrying out such a study, a questionnaire was handed into each patient who gave their consent to take part in the study. Oral lesions consisted of ulcers, erythema, leukoplakia, erythroplakia, candidiasis, angular cheilitis, median rhomboid glossitis, and denture stomatitis based on oral examination. The OHQoL were surveyed by oral health impact profile (OHIP-14) questionnaire. Data were analyzed by Pearson’s correlation test, T-test, and χ2 by SPSS software.RESULTS: A total of 121 patients with diabetes were evaluated in this study [31 males (25.6%) and 90 females (74.4%)]. In this study, there was no significant correlation between OHQoL and decayed, missing, and filled teeth, periodontal disease index. OHQoL was associated with higher ages and higher levels of blood sugar (P = 0.002, P = 0.016). The average of OHIP score significantly was increased by xerostomia experience (P = 0.010).CONCLUSION: In this survey, the influence of oral manifestation on OHQoL was low. Xerostomia was the most important symptom in diabetic patients that causes decreasing OHQoL. Age and blood sugar had more influence on this matter as well.
