This study aimed to identify the prevalence and association of periodontitis and pulp stone (PS) along with the clinical variables. This study assessed the cone-beam computed tomography (CBCT) records to identify the presence of PS and clinical periodontitis records were used to determine the stages of periodontitis. The Chi-square test was used to evaluate the relationship between study parameters. Logistic regression was used to determine the association between PS and periodontitis. A total of 228 CBCT records were conveniently selected for this study based on the inclusion and exclusion criteria. Cohen's kappa analysis showed near to perfect scores for both examiners. The Chi-square test showed that CBCT records from the age range 41-50 years, male patients, and stage II of periodontitis prevalently showed pulp stones; however, there were no significant differences observed between the PS and clinical variables. However, gender, involvement of tooth, and stages of periodontitis showed significant distribution of the PS. Logistic regression showed that the stages of periodontitis showed no significant association with PS in patients with periodontitis. Moreover, multivariate odds ratio adjustment did not alter the outcome. Periodontitis is not associated with the presence of PS in the current population.
本研究旨在确定牙周炎和髓石（PS）的患病率及其关联，以及相关临床变量。本研究评估了锥形束计算机断层扫描（CBCT）记录以确定PS的存在情况，并使用临床牙周炎记录来确定牙周炎的阶段。采用卡方检验来评估研究参数之间的关系。使用逻辑回归来确定PS与牙周炎之间的关联。根据纳入和排除标准，本研究方便地选取了228份CBCT记录。科恩kappa分析显示两位检查者的评分接近完美。卡方检验表明，年龄在41 - 50岁之间的患者、男性患者以及牙周炎II期的CBCT记录中髓石更为常见；然而，在PS与临床变量之间未观察到显著差异。不过，性别、患牙情况以及牙周炎阶段在PS分布上显示出显著差异。逻辑回归表明，在牙周炎患者中，牙周炎阶段与PS无显著关联。此外，多因素比值比调整并未改变结果。在当前人群中，牙周炎与PS的存在无关。
