Introduction: The purpose of this study was to compare the diagnostic efficacy of the naked eye, surgical operating microscope, Surgical loupe, fluorescein sodium dye, and tooth clearing technique in detecting the canal orifices of extracted maxillary 1st molar among Indian population.
Methods: A total of 50 extracted maxillary 1st molars were divided into four groups as follows: group I-naked eye, group II- surgical loupe, group III-surgical operating microscope, and group IV-fluorescein sodium dye and tooth clearing technique. After access, the opening number of root canal orifices was detected in all cases with the above methods.
Results: In the present in-vitro study, 183 canal orifices were seen by the naked eye, 184 by surgical loupe, and 186 by the surgical operative microscope, and a total of 190 canal orifices were detected by tooth clearing technique.
Conclusion: On statistical evaluation, no significant difference was seen by Chi-square analysis at p > 0.01 among various methods.
