Effect of Severity of Chronic Periodontitis on Oral Health-Related Quality of Life.

Objective:There is a paucity of studies on the relationship between the severity and type of periodontal disease and oral health related-quality of life (OHRQoL). The present study aimed to evaluate OHRQoL in patients with chronic periodontitis of different severity levels. Material and methods:In the present cross-sectional/analytical study, 200 patients with chronic periodontitis completed the OHIP-14 questionnaire. Factors such as age, gender, and chronic periodontitis severity (mild, moderate, severe) were evaluated. One-way ANOVA was used to analyze the relationship between chronic periodontitis severity and OHRQoL using SPSS 20. Results:There were significant differences in questions regarding the practical and functional domains between the two groups with mild and moderate-severe chronic periodontitis. The severity of chronic periodontitis was not significantly related to OHRQoL considering the scores of the 14 questions of the questionnaire. Variables such as gender and age did not significantly affect the OHRQoL under the effect of chronic periodontitis severity. Conclusion:Overall, the severity of chronic periodontitis did not significantly affect the OHRQoL in the present study.
