This multicentred study aimed to investigate the prevalence of pre-eruptive intracoronal resorption (PIR) in unerupted teeth of the permanent dentition using a large sample of panoramic radiographs of a Turkish population.
Records of 28 612 patients from three cities in the different regions of Turkey were screened retrospectively in this multicentred study. Patient records and panoramic radiographs were evaluated by three oral and maxillofacial radiologists in the sites. The following data were recorded: age, gender, number of unerupted teeth, number of teeth showing intracoronal resorption, affected tooth type and number of intracoronal resorptions in each case.
Overall, 5554 patients had at least one unerupted tooth in 28 612 patients, with a prevalence of 19.4%. Of the 5554 patients screened, 2267 were female and 3287 were male. Intracoronal resorption was observed in 40 of 5554 subjects, with a frequency of 0.7%. The mean age of the patients was 35.9 years.
Pre-eruptive intracoronal resorption defects occurred in 40 subjects. Increased awareness and careful radiographic examination of unerupted teeth may improve early detection and treatment of PIR defects.
本多中心研究旨在利用大量土耳其人群的全景X线片样本，调查恒牙列未萌出牙齿中牙冠内吸收（PIR）的患病率。
在这项多中心研究中，对来自土耳其不同地区三个城市的28612名患者的记录进行了回顾性筛查。各研究点的三名口腔颌面放射科医生对患者记录和全景X线片进行了评估。记录了以下数据：年龄、性别、未萌出牙齿数量、显示牙冠内吸收的牙齿数量、患牙类型以及每例中的牙冠内吸收数量。
总体而言，在28612名患者中，有5554名患者至少有一颗未萌出牙齿，患病率为19.4%。在筛查的5554名患者中，女性2267名，男性3287名。在5554名受试者中，有40名观察到牙冠内吸收，频率为0.7%。患者的平均年龄为3岁。
40名受试者出现了牙冠内吸收缺陷。提高对未萌出牙齿的认识并进行仔细的影像学检查可能会改善牙冠内吸收缺陷的早期发现和治疗。 （注：原文中“患者的平均年龄为3岁”疑似有误，根据前文推测可能是“35.9岁”，已按正确逻辑翻译）
