Cone Beam Computed Tomography Study of Root and Canal Morphology of Maxillary first Molar in an Iranian Population |
|
| چکیده فارسی مقاله |
Conclusions Most extracted maxillary first molars were three rooted and four canals. CBCT has relatively high reproducibility and accuracy of distinguishing MB2 canal. Results We found 100% of cases with three separated roots, from which 69.23% had four canals including MB2 and 30.77% with three canals. 71.3% of mesiobuccal roots were two canals of type two Vertucci and 28.7% type 4 with the mean distance value of 2.55 ± 0.57 mm between MB1 and MB2 orifice. Materials and Methods In this study, images of 156 extracted maxillary first molars placed in the waxed blocks were produced using CBCT. Two professional investigators checked images by NNT software in New Tom 3G system. Axial view and cross section of 1 mm thickness were used. The number of roots, canals, each roots canal, MB1-MB2 orifice distances and canal types of the Vertucci classification were recorded. Finally, data was analyzed using SPSS16 software. Objectives Therefore, the aim of this study was to investigate the root and canal morphology of maxillary first molars in an Iranian population using cone-beam computed tomography (CBCT). Background The success of endodontic treatment depends on detection of all root canals so that they could be cleaned, shaped and obturated appropriately. To achieve this, it is essential to know root canals complexities such as the number of canals and types of each root canal, which are genetically determined. Besides, the highest failure rates occur in maxillary first molars. |
