目的调查分析无锡地区婴幼儿患龋情况,为无锡地区保健机构进行低龄儿童龋预防干预时机选择提供依据。方法对2018年1-12月到无锡市妇幼保健院儿童口腔保健科体检的1114名12～36月龄婴幼儿患龋情况进行检查,对检查结果进行分析。结果 1114名12～36月龄婴幼儿的患龋率为11.5%,平均龋均为0.4063。最小患龋年龄为12月龄,患龋情况与年龄相关,24月龄后幼儿的患龋率显著增高,差异有统计学意义(P<0.05),且患龋程度更为严重,龋均显著升高,差异有统计学意义(P <0.05)。龋齿累计牙位存在差异,乳前牙患龋率明显高于乳磨牙,差异有统计学意义(P <0.05),其中51、61患龋率最高,分别为22.11%和21.78%。结论婴幼儿龋齿预防需将窗口期提前,预防乳前牙龋齿发生是降低婴幼儿患龋率的关键。

Objective To analysis the caries distribution of children in Wuxi,and to provide a basis for appropriate choice of the timing for oral health care in infancy.Methods Oral examination was conducted among 1114 aged 12-36 months children who received physical examination at the the Affiliated Wuxi Maternal and Child Health Care Hospital of Nanjing Medical University.The results of the examination were analyzed.Results The caries prevalence was 11.5%,with an average of 0.4063 caries.Caries prevalence is related to age.the minimum age of caries was 12 months.Dental caries increased significantly and the degree of caries was more serious from 24 months(P <0.05).The incidence of dental caries in deciduous anterior teeth was significantly higher than that in primary molars(P <0.05).Among them,51 and 61 had the highest incidence of dental caries,which were 22.11% and21.78%,respectively.Conclusions The prevention of dental caries in infants needs to advance the window period,and the prevention of dental caries in deciduous anterior teeth is the key to reduce the incidence of dental caries in infants and young children.
