对４３８名３～６岁儿童乳牙患龋情况与母亲妊娠情况及出生后第１ａ喂养方式的关系进行了调查。结果：母亲病理性妊娠的被调查儿童乳牙患龋率、乳牙龋均明显高于母亲生理性妊娠的儿童（分别为８０．９１％＞６９．５４％，５．００＞３．０６，Ｐ＜０．０５）；母亲为生理性妊娠，出生后第１ａ内人工或混合喂养的儿童乳牙患龋率、乳牙龋均、龋并发症发生率都明显高于母乳喂养６个月以上的儿童（分别为７３．７７％＞６２．６７％，３．５９＞２．２０，１３．３３％＞６．３８％，Ｐ＜０．０５）；母亲有病理性妊娠，出生后第１ａ内人工或混合喂养的儿童乳牙患龋率、乳牙龋均明显高于母乳喂养６个月以上的儿童（分别为８４．４２％＞７４．７１％，５．６４＞３．８９，Ｐ＜０．０５），但２组的龋并发症发生率都较高（分别为２４．６２％，２３．０８％）。提示：母亲病理性妊娠和婴儿出生后第１ａ人工或混合喂养对乳牙患龋率、乳牙龋均、龋病程度及龋并发症的发生均有不利影响，为制定切实可行的乳牙防龋措施提供了依据
The relationship between deciduous teeth caries in 438 children aged 3 ~ 6 years and their mothers' pregnancy and their feeding patterns after birth was investigated. Results: The caries prevalence rate and deciduous caries of mothers with pathological pregnancy were significantly higher than that of maternal physiological pregnancy (80.91%> 69.54%, 5.00> 3.06, P < 0.05). The rate of caries in deciduous teeth, caries in deciduous teeth and caries in mothers who were mothers with physiological pregnancy and were fed artificially or mixedly within the first year after birth were significantly higher than those of children breastfeeding for more than 6 months 73.77%> 62.67%, 3.59> 2.20, 13.33%> 6.38%, P <0.05). The mothers had pathological gestations, and artificial or mixed The prevalence of decayed caries in deciduous teeth and caries in deciduous teeth were significantly higher than those in breastfeeding children over 6 months (84.42%> 74.71%, 5.64> 3.89, P <0.05, respectively) However, the incidence of caries complications in both groups were higher (24.62% and 23.08%, respectively). It is suggested that maternal pathological pregnancy and postnatal day 1a artificial or mixed feeding have adverse effects on the caries prevalence of deciduous teeth, the degree of deciduous caries, the degree of cariousness and the occurrence of caries complications, so as to provide feasible deciduous deciduous caries prevention measures The basis
