摘要
Background: In leprosy, oral health is often neglected and poorly understood. This study aimed to evaluate the prevalence and risk indicators of dental caries in patients with leprosy in China. Methods: This cross-sectional, multicentre study included 613 patients with leprosy and 602 control subjects. Based on the established standards of the World Health Organization, we investigated dental caries in cluster samplings from six so-called `leprosy villages' in three Chinese provinces. Clinical oral examinations were performed and data were reported as decayed (D), missing (M) and filled (F) teeth (DMFT scores). Results: The average DMFT scores were 10.39 in patients with leprosy (D = 4.43; M = 5.94; and F = 0.02) and 4.39 in control individuals (D=2.29; M = 2.02; F = 0.08). The DMFT scores were statistically significantly different in patients with different ages, educational backgrounds and daily brushing frequency (P < 0.05). High DMFT scores were related to age, low educational levels and poor toothbrushing habits. Conclusions: The results indicate that patients with leprosy have a high prevalence of severe dental caries. Effective therapy and oral health education should be enhanced for this group of patients.
