Introduction: In order to improve caries detection, invasive methods should not be used and caries detector is useful, and antibacterial solutions can be used as well as a biological method for caries detection. Aim of the present study was to differentiate sound dentin from infectious dentin by two coloring solutions: acid red and povidone iodine.
Methods: In this experimental investigation, 140 carious molar teeth were collected. Teeth were kept in normal saline solution in room temperature and were divided into two groups, A and B (70 samples in each group). Teeth in group A were painted by acid red 1% solution and in group B by povidone iodine 10% and the painted points were recorded. After omission of the painted points, all samples of group A were painted by povidone iodine (group C) and all samples of group B by acid red (group D) and the painted points were recorded again. Data was analyzed using chi-square and Mc-Nemar tests.
Results: Diagnostic accuracy of acid red for detection of dental caries was more than povidone iodine and the difference was statistically significant (P< 0.05).
Conclusion: It was concluded that the coloring power and accuracy of acid red is more than povidone iodine.
