DIAGNOcam用于临床的初步研究

Preliminary Application of DIAGNOcam for Clinical Practice

目的:分析DIAGNOcam(DC)对不同程度邻面、牙合面龋的成像特点,评价DC诊断邻面及牙合面龋的效果。方法:对60例患者后牙依次行口内视探诊检查获得牙合面ICDAS评分(international caries detection and assessment system,ICDAS)、DC检查,可疑邻面龋行咬翼片(BWR)检查,最终547颗受检牙齿同时接受了视探诊、DC和BWR检查,检查结束后对累及牙本质的龋损行去腐充填治疗并比较不同方法对邻面及牙合面龋检查结果的相关性。结果:DC不同程度窝沟暗影延展范围与ICDAS牙合面窝沟龋评分等级(1-4)一致。DC和BWR对牙本质龋检出率的相似比达93.59%,且诊断准确度达100%。结论:DC是辅助检查诊断龋病的一种有效方法。

Objective： To analyze the imaging characteristics of proximal and occlusal carious lesions with DIAGNOcam system （DC）, and to evaluate its ability to diagnose proximal and occlusal caries. Methods： Sixty adults with complete permanent dentition were included. They were examined by visual inspection using international caries detection and assessment system （ICDAS） and DC, and if necessary, bitewing radiographs （BW）. Finally 547 teeth were examined by all three methods. Seventy-eight proximal dental carious lesions were treated operatively and the corrrelation of the examination methods were analyzed. Results： ICDAS scores （1-4） of pit and fissure caries were consistent with the extent of shadows on DC image. On the level of dentin caries, the similarity ratio of the detection rate of DC and BW was 93.59%, and the diagnostic accuracy of DC was 100%. Conclusion： DC is an effective examination method to assist the diagnosis of dental caries.
