Tooth Retention and Health Behaviors: Findings From the 4th Chinese National Oral Health Survey

Abstract

This study aimed to investigate the association between tooth retention and health behaviors among Chinese older adults. Data was used from the Chinese 4th National Oral Health Survey, a national representative sample. The sample included 9054 older adults age 55-74. The control variables included age, gender, residence, region, education level, occupation, periodontal health, self-reported oral health, and self-reported general health. Logistic regression models shows that older adults who used tooth picks (OR=3.37, 95% CI: 2.94-3.85), dental floss (OR=1.93, 95%CI: 1.05-3.53), and toothpaste (OR=3.89, 95%CI: 3.14-4.83), and never smoked (OR=1.43 95%CI: 1.20-1.70) were more likely to retain more than 20 natural teeth; while having dental visit had the opposite association (OR = 0.45, 95% CI: 0.39-052). Unexpectedly, this study did not find frequency of toothbrushing was associated with tooth retention. This study suggest that improving oral hygiene and preventive dental care are key for good oral health. .
