The purpose of the present study was to explore intervals between regular dental examination and the time dentists spent for examination and preventive dental care of children in 1996 and 2014.
In Denmark, Norway and Sweden, random samples of dentists working with children were included, while in Iceland all dentists were mailed questionnaires. Complete information was provided by 1082 of 1834 dentists (64%) in 1996 and 1366 of 2334 dentists (59%) in 2014. Results were assessed using chi-square and analysis of variance with post-hoc tests.
Some trends were consistent in all countries, but considerable differences in routines between the countries persisted during the period. The most used and maximum planned recall intervals were on average 14.8 (sd 4.8) and 18.5 (sd 4.6) months in 2014, respectively 3.1 and 3.5 months longer than in 1996 (p⟨0.05). In 2014 dentists used ample time delivering preventive care to children. Dentists reported spending significantly more time providing preventive care for caries risk children than for other children both in 1996 and 2014. Concurrent with extended intervals, dentists reported spending longer performing routine examinations in three of the four countries in 2014 than in 1996.
This study of trends in dental care delivered by dentists during recent decades showed moves towards extended recall intervals and preventive care individualized according to caries risk. In addition, extending intervals could necessitate more time for a routine dental examination.
本研究旨在探讨1996年和2014年定期牙科检查的间隔时间，以及牙医为儿童进行检查和预防性牙科护理所花费的时间。
在丹麦、挪威和瑞典，纳入了为儿童提供服务的牙医随机样本，而在冰岛，向所有牙医邮寄了调查问卷。1996年，1834名牙医中有1082名（64%）提供了完整信息；2014年，2334名牙医中有1366名（59%）提供了完整信息。使用卡方检验和方差分析以及事后检验对结果进行评估。
所有国家都存在一些一致的趋势，但在此期间各国之间的常规做法仍存在相当大的差异。2014年最常用和计划的最长召回间隔平均分别为14.8（标准差4.8）个月和18.5（标准差4.6）个月，分别比1996年长3.1个月和3.5个月（p<0.05）。2014年，牙医为儿童提供预防性护理花费了大量时间。牙医报告称，1996年和2014年，为龋齿风险儿童提供预防性护理的时间明显多于其他儿童。与间隔时间延长同时，2014年四个国家中有三个国家的牙医报告称，进行常规检查的时间比1996年更长。
这项对近几十年来牙医提供的牙科护理趋势的研究表明，召回间隔时间延长，且根据龋齿风险进行个性化预防性护理。此外，延长间隔时间可能需要更多时间进行常规牙科检查。
