To describe endodontic changes in an adult Danish population (C2;2009-2014-2019) and compare them with a similar cohort (C1;1997-2003-2008).
A randomly selected cohort (C2) with three full-mouth radiographic examinations. The frequencies of teeth, apical periodontitis (AP), root filled teeth, and lost teeth in C2 were compared to a similar cohort (C1) using regression analyses; effect of age, cohort, and period was assessed.
C1 had 330 and C2, 170 participants (mean age, C1: 42.9; C2: 47.3 years, p < .001). The proportion of individuals with no AP was similar in C1 and C2 (p = .46). C2 had a higher proportion of individuals with no root filled teeth (p < .001) and no tooth loss (p = .02) than C1. The proportion of AP and root filled teeth increased with age in both cohorts. C2 had fewer root filled teeth and lost teeth, fewest lost teeth in the youngest age groups.
In C2, the prevalence of teeth with AP and root fillings increased with age, and few teeth were lost. Change in proportion of AP was similar in two cohorts; fewer root filled teeth and lost teeth in C2. The proportion of lost teeth in C2 showed cohort effect for older age groups.
描述丹麦成年人群（C2；2009 - 2014 - 2019）的牙髓变化，并与类似队列（C1；1997 - 2003 - 2008）进行比较。
随机选取一个队列（C2）进行三次全口放射检查。使用回归分析将C2中牙齿、根尖周炎（AP）、根管充填牙和缺失牙的频率与类似队列（C1）进行比较；评估年龄、队列和时期的影响。
C1有330名参与者，C2有170名参与者（平均年龄，C1：42.9岁；C2：47.3岁，p <.001）。C1和C2中无AP个体的比例相似（p =.46）。C2中无根管充填牙的个体比例（p <.001）和无牙缺失的个体比例（p =.02）高于C1。两个队列中AP和根管充填牙的比例均随年龄增加。C2的根管充填牙和缺失牙较少，最年轻年龄组的缺失牙最少。
在C2中，患有AP和根管充填的牙齿患病率随年龄增加，且牙齿缺失较少。两个队列中AP比例的变化相似；C2的根管充填牙和缺失牙较少。C2中缺失牙的比例在老年组显示出队列效应。
