We aimed to compare an Amsterdam subpopulation's current prevalence of root canal fillings and associated periapical radiolucencies with a similar patient sample from 1988.
An Amsterdam subpopulation was evaluated for missing teeth, restorations, quality of endodontic treatment, and periapical radiolucency.
A total of 178 radiographs were evaluated and 4594 teeth were examined. Of these, 324 (7%) exhibited widening of the apical periodontal ligament or periapical radiolucency and 224 (4.8%) had been endodontically treated. A total of 118 teeth (2.5%) had radiographic signs of apical periodontitis. Of these lesions, 54 (45.7%) were linked to endodontically treated teeth (24.1% of endodontically treated teeth). Inadequate root canal fillings were frequent (55.8%). Apical radiolucency was significantly higher in these teeth than in adequately root-filled teeth.
Findings indicate that the periapical status in an Amsterdam subpopulation has not improved over almost 2 decades.
我们旨在比较阿姆斯特丹一个亚人群目前根管充填及相关根尖周透射影的患病率与1988年类似患者样本的情况。
对阿姆斯特丹一个亚人群的缺牙、修复体、根管治疗质量及根尖周透射影进行评估。
共评估了178张X线片，检查了4594颗牙齿。其中，324颗（7%）表现为根尖牙周膜增宽或根尖周透射影，224颗（4.8%）接受了根管治疗。共有118颗牙齿（2.5%）有根尖周炎的影像学表现。在这些病变中，54颗（45.7%）与根管治疗后的牙齿有关（占根管治疗牙齿的24.1%）。根管充填不充分的情况很常见（55.8%）。这些牙齿的根尖透射影明显高于根管充填合适的牙齿。
研究结果表明，近20年来阿姆斯特丹一个亚人群的根尖周状况没有改善。
