This study aims to compare the diagnostic reliability of ICDAS-II visual criteria, light-induced fluorescence (using the VistaCam iX, Dürr Dental, Bietigheim-Bissingen, Germany), and laser-induced fluorescence (using the DIAGNOdent Pen, KaVo, Biberach, Germany) on occlusal caries. Permanent and temporary molars were selected according to the inclusion criteria. Out of 160 teeth that met the inclusion criteria, 139 were chosen and examined by two previously trained and calibrated examiners. The kappa value was 0.95 for both VistaCam iX and DIAGNOdent Pen. Results from visual examination and the readings of the two fluorescence devices were computed, lesions being divided into non-cavitated, enamel lesions, and lesions extended to dentin. All statistical analyses were performed using R (version 4.2.2). Spearman’s rank correlation was computed to assess the relationship between the scores of diagnostics reliabilities of the three methods mentioned above. There was a positive, statistically significant Spearman’s rank correlation coefficient, ρ = 0.25, between VistaCam iX and ICDAS II, and a positive, not statistically significant Spearman’s rank correlation coefficient, ρ = 0.11, between DiagnoDent Pen and ICDAS II. Considering the temporary teeth, there was a positive, statistically significant Spearman’s rank correlation coefficient, ρ = 0.52, between VistaCam iX and DiagnoDent Pen; a positive, statistically significant Spearman’s rank correlation coefficient, ρ = 0.35, between VistaCam iX and ICDAS II; and the lowest, not statistically significant Spearman’s rank correlation coefficient, ρ = 0.16, between DiagnoDent Pen and ICDAS II. Conclusions: In conclusion, ICDAS II and light-induced fluorescence are better diagnostic methods than the laser-induced fluorescence devices for detecting occlusal caries. Clinical Significance: This study may support clinicians in selecting the most efficient tool for diagnosing carious lesion in the earliest stages possible. Furthermore, such technologies raise the availability for more preventive approaches, as opposed to invasive procedures.
