Objective: This micro-computed tomography (MCT) study investigated the utility of thin-slab minimum-intensity projection (TS-MinIP) technique as an adjunct to 3-dimensional (3D) modeling for in-depth morphology study. Study design: One hundred one extracted maxillary first molars were scanned for microtomographic analysis (SkyScan). Two-dimensional TS-MinIP and 3D images of mesiobuccal (MB) roots were produced and analyzed to record the number and configurations of the canals, the incidence and location of accessory canals, loop, and intercanal connections, and number of foramina. Results: Multiple-canal MB roots were present in 76.2%, and all of the roots had intercanal communications. Weine type III configuration was the most common in the multiple-canal roots. Accessory canals were found in 78.2% of the roots. Configurations that were nonclassifiable were found in 10.9% of the MB roots. Conclusions: MB root canal anatomy was complex, and MinIP may serve as an adjunct to 3D modeling for in-depth morphology study.
