AIM
This study determined the prevalence and distribution of pulp stones in the permanent dentition of an adult population using their periapical radiographs.
MATERIALS AND METHODS
The study followed a cross-sectional design. A total of 800 periapical radiographs collected from 412 patients attending dental clinics in Kerman, Islamic Republic of Iran, were examined using magnification.
RESULTS
Pulp stones were present in 9.6% of all permanent teeth examined, being most common in maxillary first and second molars, followed by mandibular first and second molars. They were present in 31.5% of all adult patients, with a significantly increased prevalence in females compared with males (40.5 vs 23.9%, chi-squared test p < 0.001). There was also an increased prevalence with age.
CONCLUSION
Based on the results of this study, clinicians should expect to encounter pulp stones most commonly in the pulp chambers of maxillary first and second molars, particularly in older female patients.
CLINICAL SIGNIFICANCE
Pulp stones depending on their size and location can pose challenges to endodontic treatment. They obstruct access to the canal orifices and thus complicate endodontic treatment. Knowing where and when pulp stones are likely to occur improves the quality of root canal treatments.
目的
本研究利用根尖片确定成年人群恒牙列中髓石的患病率及分布情况。
材料与方法
本研究采用横断面设计。使用放大设备检查了从伊朗伊斯兰共和国克尔曼市牙科诊所的412名患者收集的总共800张根尖片。
结果
在所检查的所有恒牙中，9.6%存在髓石，最常见于上颌第一和第二磨牙，其次是下颌第一和第二磨牙。在所有成年患者中，31.5%存在髓石，女性患病率显著高于男性（40.5%对23.9%，卡方检验p<0.001）。患病率也随年龄增加。
结论
基于本研究结果，临床医生应预计在上颌第一和第二磨牙的髓室中最常遇到髓石，尤其是老年女性患者。
临床意义
髓石根据其大小和位置可能给牙髓治疗带来挑战。它们会阻碍进入根管口，从而使牙髓治疗复杂化。了解髓石可能出现的位置和时间可提高根管治疗的质量。
