A decreasing proportion of children require operative treatment each year and an increasing proportion of children will at recall require no operative care. This would provide resources to give individualised prevention to children at risk for developing new carious lesions. From 3 years of age, however, the prevalence of caries increases up to the age when the primary dentition exfoliates, even though the children attend regular dental service programmes yearly, and for some children dental caries remains a significant problem. The purpose of the present study was to describe the dental health of a group of 6-year-old children living in Sweden, with special reference to caries prevalence at 3 years of age and to immigrant status. At 6 years of age, 45% of the children were free of initial and manifest carious lesions in the primary cuspids and molars. The mean caries increment between 3 and 6 years was 0.9 tooth surfaces for children who were caries free at 3 years of age compared to 4.5 tooth surfaces for children with manifest carious lesions at the same age. The mean caries increment from 3 to 6 years was 1.3 in the non-immigrant group and 3.6 in the immigrant group. For the majority of the children in this study, current preventive dental care seems sufficient. However, for about one-third of the children (children with carious lesions at 3 years of age and/or immigrant status), current caries preventive programme used in the Public Dental Service are inadequate.
每年需要手术治疗的儿童比例在下降，而需要复诊但无需手术治疗的儿童比例在上升。这将为有患新发龋损风险的儿童提供个性化预防的资源。然而，从3岁起，龋病患病率会持续上升，直至乳牙列脱落的年龄，即便这些儿童每年都参加常规的牙科服务项目，而且对一些儿童来说，龋齿仍然是一个严重的问题。本研究的目的是描述一群生活在瑞典的6岁儿童的口腔健康状况，特别提及3岁时的龋病患病率以及移民身份。在6岁时，45%的儿童在乳尖牙和磨牙上没有初始龋损和明显龋损。3岁时无龋的儿童在3至6岁期间的平均龋损增加量为0.9个牙面，而同龄有明显龋损的儿童为4.5个牙面。非移民组3至6岁期间的平均龋损增加量为1.3，移民组为3.6。对于本研究中的大多数儿童来说，目前的预防性牙科护理似乎足够。然而，对于约三分之一的儿童（3岁时有龋损和/或有移民身份的儿童），公共牙科服务中目前使用的龋病预防项目并不充分。
