Abstract

Objective To investigate the level and influencing factors of oral health-related quality of life in patients with chronic periodontal disease. Methods 280 patients with chronic periodontal disease were investigated, using Pearson, Spearman correlation and multivariate linear regression to identify influencing factors of oral health-related quality of life. Results The oral health impact profile was in the middle level with a total score of 16.93±7.37. The influencing factors were self-efficacy for self-care, dental fear and entering into supportive periodontal therapy, which contributed 24.0% of the variance. Conclusions The oral health-related quality of life in patients with chronic periodontal disease is in low level. In order to improve the oral health-related quality of life in patients with chronic periodontal disease, health care providers should strengthen patients′ self-efficacy and reduce the patients′ dental fear.
