The aim of this study was to determine the prevalence of pulp stones in the Malaysian population using radiographs, and to assess the association of pulp stones with gender, age, tooth type, dental arch and tooth status. Occurrence of pulp stones among the three races in Malaysia (Malay, Chinese and Indians) was also studied.
A retrospective study was performed from a random sample of 361 dental records in AIMST Dental Centre, Faculty of Dentistry, AIMST University, Kedah, Malaysia. Data were collected from patient files and 507 intraoral periapical radiographs. All radiographs were examined by an oral radiologist to identify pulp stones and associated factors. Statistical analysis was performed using the Pearson chi-square test.
Of the 361 patients, 205 were female and 156 were male. Pulp stones were identified in 162 (44.9%) subjects in 1 or more teeth and in 280 (15.7%) teeth of the total 1779 teeth examined. Pulp stones were found significantly more in molars and teeth that were not intact (carious/restored/both carious and restored). There was no significant correlation with sex, increasing age, dental arches, and ethnic races.
The prevalence of pulp stones in the Malaysian population studied was 44.9%. Pulp stones were more often seen in teeth that were restored or affected with caries. These findings require further investigation.
本研究旨在通过X光片确定马来西亚人群中髓石的患病率，并评估髓石与性别、年龄、牙型、牙弓和牙齿状况之间的关联。同时还研究了马来西亚三个种族（马来人、华人及印度人）中髓石的发生情况。
对马来西亚吉打州艾迈斯特大学牙科学院艾迈斯特牙科中心的361份牙科记录随机样本进行回顾性研究。数据从患者档案和507张口腔根尖片收集。所有X光片均由口腔放射科医生检查，以识别髓石及相关因素。采用Pearson卡方检验进行统计分析。
361名患者中，女性205名，男性156名。在162名（44.9%）受试者的1颗或多颗牙齿中发现了髓石，在总共检查的1779颗牙齿中的280颗（15.7%）牙齿中发现了髓石。在磨牙以及非完整牙齿（龋坏/修复/龋坏且修复）中发现髓石的情况明显更多。与性别、年龄增长、牙弓和种族没有显著相关性。
所研究的马来西亚人群中髓石的患病率为44.9%。髓石在修复或患龋的牙齿中更常见。这些发现需要进一步研究。
