Aim: to assess the reliability of the fluorescence camera or caries detection dye versus visual tactile method in caries excavation using bacteriological assessment method. Materials and Methods: 60 carious lesions in 20 paticipant (3 in each paticipant) was chosen in this study. In each participant , there had been 3 carious lesions ; the excavation end point of one cavity was determined using visual tactile method. The two other cavities were inspected using the fluorescent camera and caries detector dye (CDD) to determine the excavation endpoint respectively. Dentine samples from the three cavities were collected before and after caries excavation for the bacteriological assessment. Results: the Visual tactile method showed lowest reduction in the bacterial count followed by Caries detector dye followed by the highest reduction for Fluorescent camera with a statistically significant difference between each other{u2019}s. Conclusion: the light induced fluorescent intraoral camera is more effective in removing infected dentin and in reaching the excavation endpoint
