The study material consisted of 1417 children 6-8 years old representing 86% of a stratified random sample from the Finnish population. Data on caries and social class were obtained by questionnaire from the municipal dental clinics in 1978. Clinical findings for primary teeth were recorded by local dentists. Incisors were excluded from the study. 80% of the children had caries lesions, and 63% were in need of restorative care. Mean dmft value was 4.4 mean dt, ft, and mt values were 2.3, 2.6 and 0.3, respectively. Occurrence of untreated caries lesions did not vary according to age. Compared to the girls, boys had lost twice as many teeth due to caries. No other differences were observed between sexes. Both past caries experience and need of restorative care increased continuously from the highest social class to the lowest. Observed regional differences were explained mainly by variation in social stratification, except in an area with abundant natural fluoride. More active dental care is needed for children with primary teeth, especially in lower social class.
研究材料包括1417名6至8岁的儿童，占芬兰人口分层随机样本的86%。1978年通过问卷调查从市政牙科诊所获取了龋齿和社会阶层的数据。当地牙医记录了乳牙的临床检查结果。该研究排除了切牙。80%的儿童有龋损，63%需要修复治疗。平均dmft值为4.4，平均dt、ft和mt值分别为2.3、2.6和0.3。未治疗龋损的发生率不因年龄而异。与女孩相比，男孩因龋齿而缺失的牙齿数量是女孩的两倍。未观察到性别之间的其他差异。过去的龋齿经历和修复治疗需求均从最高社会阶层到最低社会阶层持续增加。观察到的地区差异主要由社会分层的差异来解释，但有丰富天然氟化物的地区除外。乳牙儿童需要更积极的牙科护理，尤其是在社会阶层较低的儿童中。
