ENDODONTIC TREATMENT ON MAXILLARY FIRST MOLAR WITH FOUR ROOTS AND FIVE ROOT CANALS USING A MICROSCOPE AND THE CONE-BEAM COMPUTED TOMOGRAPHY

抄録

In the present study, we had an opportunity to perform endodontic treatment under a surgical operating microscope after understanding that 4 roots and 5 separate root canals are present based on CBCT images before the treatment of maxillary left first molar. By CBCT, it is possible to evaluate up to three-dimensional conditions after root canal filling, which cannot be correctly judged by intraoral periapical radiography. These can be explanatory materials, which can be easily understood by the patients. The use of a surgical operating microscope and CBCT imaging helps the clinician to diagnose unusual anatomy of a tooth and facilitate successful endodontic treatment.
