Quality Of Life Related To Oral Health In Chinese Patients

Oral health is a part of overall health and is considered an important component of quality of life. Dental caries and periodontal disease are progressive processes, and improper treatment can lead to tooth loss, thereby affecting quality of life. This study, utilizing data from the World Dental Federation Oral Health Observatory (OHO) project, aims to investigate oral health-related quality of life (OHQoL) among Chinese adults, evaluate its influencing factors, and provide recommendations for health education and oral disease prevention. A cross-sectional study included 2,233 adults via modified systematic sampling. The oral diseases of each patient were assessed by dentists using an examination questionnaire. Structured questionnaire gathered data on sociodemographics, personal oral health behaviors, and OHQoL scores. Logistic regression analysis was used to identify protective and risk factors associated with oral health-related quality of life. Socio-demographic factors (male, older age, lower education), poor oral health (denture use, periodontal disease), and unhealthy oral care behaviors (brushing <2 times/day, smoking/alcohol consumption) were significantly associated with higher OHQoL scores (greater negative life impact) and more missing teeth. Worse self-rated systemic and oral health correlated with higher OHQoL scores and increased missing teeth, indicating a bidirectional link between subjective health perception and objective oral conditions. OHQoL and missing teeth are influenced by socio-demographic factors, oral health behaviors, and subjective health perceptions, necessitating comprehensive intervention strategies to improve the connection between oral health management and quality of life.
