Abstract
Statement of Problem: It has been claimed that for enhancement of caries detection, dyes are useful. Antibacterial solution may be considered as a good choice compared with visual- tactile method in caries detection.Purpose: The purpose of the this study was to evaluate the accuracy of two caries detector dyes in comparison with visual -tactile method, in detection of dental caries. Materials and Method: In this experimental study, 246 carious posterior teeth were selected and caries removal was performed. The teeth were randomly divided into two groups. In Group A, the teeth were stained with Povidone- Iodine 10% solution, and teeth in group B were stained with Acid Red 1% solution. Stained area were recorded. Eighty teeth were randomly selected from each groups and stained area were removed. Teeth from Group B were stained with Povidone-Iodine (group C) and those from group A were stained with Acid Red,(group D) and again the stained area were recorded. Results of stained area in all groups were analyzed by Chi square and Fisher’s Exact tests ( p <0.05).Results: Significant differences were found between visual- tactile assessment and caries detector dyes. Caries detection by using dyes was more effective than visual- tactile method. There was significant difference between Poviodone-iodine and Acid Red solution in detection of caries ( p < 0.05).Conclusion: More accurate caries detection is obtained by using Acid Red and Povidone- Iodine in comparison with visual- tactile method.Key words: Caries detector, Povidone-Iodine, Acid Red, Visual- tactile
