The aim of the study was to determine the reproducibility and validity of DIAGNOdent in detecting active and arrested caries lesions on free smooth surfaces. Volunteers were selected from state schools of Piracicaba, São Paulo, Brazil. Overall, 220 lesions were clinically examined. Two specially trained ('calibrated') examiners performed both clinical and laser evaluations independently, and after a 1-week interval, the examinations were repeated. The intra-examiner agreement for the laser evaluation was substantial (kappa(ex1) = 0.79, kappa(ex2) = 0.71). There was almost perfect agreement between the two examiners for the clinical examination (kappa(ex1) = 0.95, kappa(ex2) = 0.85). The inter-examiner agreement showed substantial reproducibility (kappa = 0.77) for the laser examination and almost perfect agreement (kappa = 0.85) for the clinical evaluation. The validation criterion was the clinical examination of white spots, recorded as active or arrested. The sensitivity was 0.72 and the specificity was 0.73, which indicates that the DIAGNOdent was a good auxiliary method for detecting incipient caries lesions on free smooth surfaces. The utilization of both methods can improve the efficacy of caries diagnosis.
本研究的目的是确定DIAGNOdent在检测游离光滑表面上的活动龋损和静止龋损时的可重复性和有效性。志愿者选自巴西圣保罗皮拉西卡巴市的公立学校。总共对220个病损进行了临床检查。两名经过专门培训（“校准”）的检查者独立进行临床和激光评估，间隔1周后重复检查。激光评估的检查者内一致性较高（kappa（ex1）=0.79，kappa（ex2）=0.71）。两名检查者在临床检查方面几乎完全一致（kappa（ex1）=0.95，kappa（ex2）=0.85）。检查者间一致性显示激光检查具有较高的可重复性（kappa=0.77），临床评估几乎完全一致（kappa=0.85）。验证标准是对白斑进行临床检查，记录为活动或静止。敏感性为0.72，特异性为0.73，这表明DIAGNOdent是检测游离光滑表面早期龋损的良好辅助方法。两种方法的联合使用可提高龋病诊断的效果。
