ObjectiveTo investigate the caries status and its influencing factors of all hearing-impaired children in a hearing and speech rehabilitation center in Nanning, Guangxi. MethodsIn accordance with the requirements of the fourth national oral health epidemiological survey, all hearing-impaired children in a hearing and speech rehabilitation center in Nanning, Guangxi were examined for oral health, and their parents were surveyed with oral health questionnaires. Univariate analysis and multivariate logistic regression model were used to identify influencing factors for caries in hearing-impaired children. ResultsThe total caries rate of hearing-impaired children was 73.0%, and the average caries was 5.52. There was no statistically significant difference in the prevalence of caries between hearing-impaired children of different genders (P＞0.05). The results of multivariate logistic regression analysis showed that occasional or frequent intake of sweets/sweet drinks before bedtime and occasionally or frequently holding food in their mouth without swallowing at meals were risk factors for caries in hearing-impaired children (all P＜0.05). ConclusionThe caries status of hearing-impaired children is severe, and occasional or frequent intake of sweets/sweet drinks before bedtime and occasionally or frequently holding food in their mouth without swallowing at meals are risk factors for caries in hearing-impaired children.
