This study aimed to assess the effectiveness of Dental-operating microscope (DOM) for detection of second mesiobuccal canal (MB-2) in extracted maxillary first and second molars compared with unaided vision.
One hundred extracted permanent maxillary first and second molars (50 each) were taken. The location of MB-2 canal was attempted using an endodontic explorer with naked eye. Teeth, in which MB-2 canal was failed to locate, were further explored under DOM. Finally, the mesiobuccal roots of each tooth were sectioned and observed at a magnification of 12X to confirm the actual presence of MB-2 canal. The results were analyzed by screening test.
In maxillary first molars, 21 (42%) MB-2 canals were identified with naked eye, 9 with DOM making a total of 30 (60%), and additional 3 with sectioned roots under DOM bringing the total to 33 (66%). Whereas, in maxillary second molars total 10 (20%) MB-2 canals were identified with naked eye, while nine were identified with DOM bringing the total to 19 (38%), and additional 2 when observing the sectioned roots under DOM bringing the total to 21 (42%).
The results of this study demonstrate that the adjunctive use of DOM may assist the dental clinician in locating the MB-2 canal orifice.
