In conjunction with an epidemiological study of oral health in women the capacity of the panoramic radiograph to yield information on oral conditions was compared to that of the intraoral full mouth survey including posterior bitewing radiographs. Full mouth surveys and panoramic radiographs of 75 women were compared for gross characteristics such as distribution of teeth, missing teeth, restorations, and endodontic treatment as well as for osteolytic lesions at the root, marginal bone loss and carious lesions. A nearly 100% agreement was found for gross characteristics but also for osteolytic lesions associated with teeth and for marginal bone loss the agreement was good; osteolytic lesions at single rooted teeth 76%, multirooted teeth 90% and a coefficient of correlation of .96 for individual mean marginal bone scores. Poor agreement was found for carious lesions as only 36% of those extending well into the dentine were found both in the intraoral radiographs and in the panoramic radiographs. It may be included that, except for carious lesions, the panoramic radiographs can be considered a useful tool in epidemiological studies of oral health.
在一项关于女性口腔健康的流行病学研究中，将全景X线片获取口腔状况信息的能力与包括后牙咬合翼片在内的口腔全口检查的能力进行了比较。对75名女性的全口检查和全景X线片进行了比较，比较内容包括牙齿分布、缺失牙、修复体、牙髓治疗等总体特征，以及牙根处的溶骨性病变、边缘骨丧失和龋损。结果发现，在总体特征方面，以及与牙齿相关的溶骨性病变和边缘骨丧失方面，一致性接近100%；单根牙的溶骨性病变一致性为76%，多根牙为90%，个体平均边缘骨评分的相关系数为0.96。对于龋损，一致性较差，因为在口腔内X线片和全景X线片中，只有36%深入牙本质的龋损被同时发现。可以得出结论，除了龋损外，全景X线片可被视为口腔健康流行病学研究中的一种有用工具。
