Abstract

Introduction: Periodontal disease is one of the most important diseases in health topics. The aim of this study was to determine the effect of periodontal treatment on quality of life. Materials and methods: In this quasi-experimental, interventional study, 45 patients with chronic periodontitis were asked to complete the “quality of life” questionnaire before starting the treatment and four months after periodontal therapy. Then the questioners were evaluated and scored. Wilcoxon’s test was used to compare each question before and after treatment. Paired t-test was used to compare quality of life indices before and after treatment. T-test was used to compare the quality of life indices between males and females and between patients with mild to moderate and moderate to severe periodontitis (α=0.05). Results: The mean scores of all the indices of quality of life, including sports, nutrition, stress control, business activity, physical status and appearance, sleep and rest, social relations and physical health, showed significant differences before and after periodontal treatment (p value < 0.001). Differences between the mean scores of indices of quality of life after periodontal treatment in females were higher than males, but they exhibited significant differences only in sports and business activity (p value = 0.006 and p value = 0.004, respectively). There were no statistically significant differences in the mean scores of all the indices evaluated in patients with mild to moderate periodontitis and with moderate to severe periodontitis before and after treatment (p value > 0.05). Conclusion: Under the limitations of the present study, it can be concluded that periodontal treatment improves the quality of life.     Key words: Oral health, Periodontal diseases, Quality of life.
