One hundred 14-yr-old children were observed over 1 yr to find out if caries incidence and caries progression could be predicted in a low prevalence child population by means of well-known caries related factors. The mean caries incidence was low (0.45, SD 0.70) but, on the other hand, 32% of the children developed at least one new lesion during the test period. In only eight out of 35 children progressing lesions were demonstrated. Independent variables at baseline examination were caries prevalence, sucrose intake, fluoride exposure, oral hygiene, saliva secretion rate, and salivary concentrations of mutans streptococci and lactobacilli. A weak but statistically significant correlation was demonstrated between caries incidence and caries prevalence. No other significant correlations were shown. It was concluded that caries activity could not be predicted in this population. Low disease prevalence was a major reason for the weak correlations.
对100名14岁儿童进行了为期1年的观察，以确定在低患龋率儿童群体中，是否可以通过众所周知的龋病相关因素来预测龋病发病率和龋病进展情况。平均龋病发病率较低（0.45，标准差0.70），但另一方面，32%的儿童在测试期间至少出现了一个新的龋损。在35名有龋病进展的儿童中，只有8名被证实有进展性病变。基线检查时的自变量包括龋病患病率、蔗糖摄入量、氟暴露、口腔卫生、唾液分泌率以及变形链球菌和乳酸杆菌的唾液浓度。龋病发病率与龋病患病率之间存在微弱但具有统计学意义的相关性。未显示其他显著相关性。得出的结论是，无法在该人群中预测龋病活性。低疾病患病率是相关性较弱的主要原因。
