对１１０ 名３ ～４ 岁幼儿进行口腔检查，记录其初始患龋状况，调查其刷牙习惯和父母龋患状况；取全部受检幼儿未刺激全唾液，测定 Ｐ Ｈ 值、 Ｈ Ｃ Ｏ－３ 浓度和溶菌酶（ Ｌ Ｚ Ｍ） 、乳酸脱氢酶（ Ｌ Ｄ Ｈ） 、碱性磷酸酶（ Ａ Ｋ Ｐ） 活性，２年后复查幼儿新发龋情况。结果表明，父母龋活跃性、幼儿唾液 Ｌ Ｚ Ｍ 活性在无龋组（ｄｆｔ＝ ０） 和多龋组（ｄｆｔ≥５） 间有显著差异。以父母龋活跃性、幼儿唾液 Ｌ Ｚ Ｍ 活性和幼儿初始患龋状况为判定指标的 Ｃ Ａ Ｔ 有临床价值。
A total of 110 children aged 3 to 4 years old were examined for oral cavity, their initial caries were recorded, their brushing habits and their caries status were investigated. Total saliva was not stimulated in all the children examined, P H value and H C O-3 concentration And L Z M, L D H, and A K P activities. After 2 years, the newly diagnosed caries in children were reviewed. The results showed that there was a significant difference in parent caries activity and LZ M activity in infant caries between caries-free group (dft = 0) and multi-caries group (dft≥5). The clinical value of C A T, which is based on the activity of parental caries, the activity of saliva in young children and the initial caries status in young children, is of great value.
