This study aimed to assess the presence of pulp stones through an examination of cone beam computed tomography images and correlate their prevalence with age, sex, dental arch and side, tooth type, and restoration type and depth.
Cone beam computed tomography images obtained from 673 patients and archival data on 11,494 teeth were evaluated. The associations of pulp stones with age, sex, dental arch and side, tooth type, and restoration type and depth were noted. All the measurements were subjected to a χ test and one sample χ test ( < 0.05).
In the study group, 163 (24.2%) patients and 379 (3.3%) teeth had at least one pulp stone. The pulp stone frequency in those aged 30-39 years was significantly greater than in those aged 18-29 and ≥ 60 years, and the frequency was higher in females than in males ( < 0.05). The highest prevalence of pulp stones was found in maxillary dental arches and molar teeth ( < 0.05). Pulp stones were significantly more common in medium-depth restorations ( < 0.05).
Maxillary molar teeth, medium-depth restorations, individuals aged 30-39 years and females had a greater percentage of pulp stones.
本研究旨在通过锥束计算机断层扫描图像检查评估髓石的存在情况，并将其患病率与年龄、性别、牙弓和牙侧、牙齿类型、修复类型及深度相关联。
对从673例患者获取的锥束计算机断层扫描图像以及11494颗牙齿的存档数据进行评估。记录髓石与年龄、性别、牙弓和牙侧、牙齿类型、修复类型及深度之间的关联。所有测量均进行χ检验和单样本χ检验（P<0.05）。
在研究组中，163例（24.2%）患者和379颗（3.3%）牙齿至少有一颗髓石。30 - 39岁人群的髓石发生率显著高于18 - 29岁和≥60岁人群，女性的发生率高于男性（P<0.05）。髓石患病率最高的是上颌牙弓和磨牙（P<0.05）。中深度修复体中髓石明显更常见（P<0.05）。
上颌磨牙、中深度修复体、30 - 39岁个体及女性的髓石比例更高。
