Abstract

The purpose of study was to compare the laser fluorescence detection by Diagnodent(KaVo, Germany), visual inspection using dental explorers, and conventional dental radiography as diagnostic tests for dental caries. One hundred and three human premolars and molars which had no caries or fissure caries were tested by the three methods. Diagnodent scores increased as the scores of the other two tests increased(P<0.01) There were significant relationships between visual inspection scores and Diagnodent scores(Pearson 0.676, Spearman 0.694) and between radiography scores and Diagnodent scores(Pearson 0.623, Spearman 0.658) (P<0.01, all). Diagnodent test proved to have high sensitivity and low specificity and more studies are necessary to present the diagnostic criteria for progressive caries stages.
