The aim of this study was to compare conventional radiography, storage phosphor plate, and cone beam computed tomography for in vitro determination of occlusal and approximal caries.
A total of 72 extracted human premolar and molar teeth were selected. Teeth were radiographed with conventional intraoral radiography, a storage phosphor plate system, and cone beam computed tomography and evaluated by two observers. The teeth were then separated and examined with a stereomicroscope and a scanner at approximately 8×magnification.
CBCT was statistically superior to conventional radiography and phosphor plate for determining occlusal caries. No significant difference from CBCT, conventional radiography and the phosphor plate system for determining approximal caries was found.
The CBCT system may be used as an auxiliary method for the detection of caries.
本研究旨在比较传统射线摄影、存储磷光板和锥形束 CT 在体外检测窝沟和邻面龋中的应用。
选择 72 颗离体人第一前磨牙和磨牙。对牙齿进行传统的口腔内射线摄影、存储磷光板系统和锥形束 CT 拍摄，并由两名观察者进行评估。然后将牙齿分离，用立体显微镜和扫描仪以大约 8×的放大倍数进行检查。
CBCT 在确定窝沟龋方面明显优于传统射线摄影和磷光板。在确定邻面龋方面，CBCT 与传统射线摄影和磷光板系统无显著差异。
CBCT 系统可作为龋齿检测的辅助方法。
