To investigate the prevalence of apical periodontitis (AP) and the technical standard of root canal treatment in a Belgian population, assess the association of different variables with periapical status, and compare the results to a similar study conducted 22 years previously.
In this cross-sectional study, 614 panoramic radiographs of first-time adult attendees at the Dental School of the University Hospital of Ghent were examined. Recorded patient-level parameters included gender, age, number of teeth, number of root filled teeth, presence of any AP lesion, and number of implants. The following tooth-level data were collected: tooth presence, coronal status, quality of coronal restoration, post presence, type of root-filling material, length and density of root filling, root-end filling material, presence of AP, and adjacent implant. Multivariable multilevel binary logistic regression was used to explore the association between patient and tooth characteristics and AP prevalence. Risk differences and confidence intervals were calculated to compare the present with the previous study.
The prevalence of AP at patient and tooth level was 46.9% and 5.6%, respectively. Fifty-one per cent of the 614 patients had at least one root filled tooth, and 5.9% of the 14 655 teeth studied were root filled. AP was found in 45% of root filled teeth. Fifty-four per cent of the root-filled teeth were rated as inadequate. Multivariable multilevel logistic regression revealed that more teeth, more implants, fewer root-filled teeth, adequate density, adequate coronal restoration, and no caries reduced the likelihood of AP. There were no statistically significant differences between the two studies regarding the prevalence of root-filled teeth or AP and the technical quality of root canal treatment.
The prevalence of AP and the technical quality of root canal treatment in Belgium have not substantially changed over the last 22 years, despite the technological advancements and continuing education in the field.
调查比利时人群中根尖周炎（AP）的患病率和根管治疗技术标准，评估不同变量与根尖状态的关系，并将结果与 22 年前进行的类似研究进行比较。
在这项横断面研究中，检查了根特大学医院牙科学校首次就诊的 614 名成年患者的全景片。记录的患者水平参数包括性别、年龄、牙齿数量、根管治疗牙齿数量、是否存在任何 AP 病变以及植入物数量。收集了以下牙齿水平数据：牙齿存在、冠部状况、冠部修复质量、桩存在、根充材料类型、根充长度和密度、根尖封闭材料、AP 存在以及相邻植入物。采用多变量多级二分类逻辑回归分析探讨患者和牙齿特征与 AP 患病率之间的关系。计算风险差异和置信区间，以比较本研究与前一项研究。
患者和牙齿水平的 AP 患病率分别为 46.9%和 5.6%。614 名患者中有 51%至少有一颗根管治疗牙，14655 颗研究牙中有 5.9%进行了根管治疗。45%的根管治疗牙发现 AP。54%的根管治疗牙被评为不充分。多变量多级逻辑回归显示，更多的牙齿、更多的植入物、更少的根管治疗牙、适当的密度、适当的冠部修复和无龋齿降低了 AP 的可能性。两项研究在根管治疗牙或 AP 的患病率和根管治疗技术质量方面没有统计学上的显著差异。
尽管该领域的技术进步和继续教育不断发展，但过去 22 年来，比利时的 AP 患病率和根管治疗技术质量并未发生实质性变化。
