An Investigation Of Prevalence And Risk Factors Of Caries In Deciduous Teeth Among Children Of Aged 5 In Fuzhou

Objective To identify some risk factors related to caries in deciduous teeth from preventive medical direction as early as possible and provide scientific evidence for decision-making for prevention. Methods Through investigating the oral healthy condition among children of aged 5 in Fuzhou, and making a further analysis for the social and behavioral factors, we try to identify some risk factors related to caries in deciduous teeth.

The filling rate was low. The highest prevalence rate of caries was the deciduous incisors in the maxillary. 42.91% of the children had 79.50% caries in deciduous teeth. During the general characters, the elder age of father, the long educational years of parents, the high-income levels were protective factors.Talking about mother's complex diseases during their pregnancies and parturitions, the weightier birth weight, enough pregnant months, natural parturition, the elder parturient age of mother were protective factors.During infant periods, sugar-contained drugs taken frequently, taking drugs between two meals were risk factors.In the feeding habits, suckling mother's breast frequently, having sleep by drinking mother's milk, bottle-feeding too late, using milk bottle too long every time, drinking fruit juice and sweet milk before sleep, eating snacks frequently, not enough supplemented foods ,being taken care of by mother between 12 months to 3-years-old were risk factors.In oral hygiene habits, cleaning teeth early and with parents' helps, brushing teeth everyday were protective factors.The presences of visiting dentists in serious caries children were higher than that in caries free children because of their treatment needs.
