The aim of this study was to follow attendance patterns longitudinally by exploring length of intervals between routine dental examinations in children at the ages of 5 and 12 years, and study associations between length of recall intervals and caries prevalence, controlled for gender, parent's background and parent's education. The study included 2960 children in one Norwegian county monitored from 5 to 12 years of age. Data were collected at clinical examinations, from dental records and by parental questionnaires. Length of recall intervals was dichotomized into short (shorter than 18 months) and long (18 months and longer). Data were analysed and tested using Chi-square statistics, correlation coefficient and multivariate regression. The study was ethically approved. Recall intervals were individualized and varied from 4 to 30 months. The most frequent used recall intervals were 12, 18, 20 and 24 months. A majority of children at both ages were given long recall intervals. Multivariate logistic regression showed that the probability of having short interval was higher in children having caries experience than in caries-free children at both 5 years (OR 12.6 CI 9.9-16.0) and 12 years (OR 2.7 CI 2.3-3.1). At 5 years of age, length of recall intervals was associated with parents' background (OR 1.8 CI 1.4-2.4) and parents' education (OR 1.3 CI 1.0-1.5). The results showed that routine intervals were individualized and extended, indicating that more resources were spent on children with the highest need of dental care, aiming at reducing health inequalities.
本研究旨在通过探索儿童在 5 岁和 12 岁时常规牙科检查之间的间隔时间的长短，来跟踪就诊模式的纵向变化，并研究回忆间隔时间的长短与龋齿患病率之间的关联，同时控制性别、父母背景和父母教育等因素。该研究纳入了挪威一个县的 2960 名儿童，从 5 岁到 12 岁进行监测。数据收集来自临床检查、牙科记录和家长问卷。回忆间隔时间被分为短（短于 18 个月）和长（18 个月及以上）两种。使用卡方检验、相关系数和多元回归分析数据。该研究获得了伦理批准。回忆间隔时间是个体化的，从 4 到 30 个月不等。最常用的回忆间隔时间为 12、18、20 和 24 个月。大多数儿童在两个年龄段都被给予长的回忆间隔时间。多元逻辑回归显示，在 5 岁和 12 岁时，有龋齿经历的儿童比无龋齿的儿童更有可能接受短的回忆间隔时间（5 岁时的比值比[OR]为 12.6，95%置信区间[CI]为 9.9-16.0；12 岁时的 OR 为 2.7，95%CI 为 2.3-3.1）。在 5 岁时，回忆间隔时间与父母背景（OR 1.8，95%CI 1.4-2.4）和父母教育（OR 1.3，95%CI 1.0-1.5）有关。研究结果表明，常规间隔时间是个体化和延长的，这表明更多的资源被用于最需要口腔护理的儿童身上，旨在减少健康不平等。
