“…The most common root canal configurations were types 3-2, 2-3, 1-3 and 3-3. More complex configurations such 1-2-1-3, 1-2-3-2, 2-3-2-1-2, 2-3-2-3-2 and 3-2-1-2-1 have been also reported in some laboratory studies (14,24,28). In the clinical case reports, type 3-2 was the predominant configuration and it occurred in three forms ( The three root canals are usually located on a straight line and the distance between their orifices ranges from 1 to 2 mm (29,42,46,57).…”

INTRODUCTION The knowledge of root canal anatomy is essential to ensure a successful outcome of surgical and nonsurgical root canal treatment. The aims of this article were to present 2 cases of maxillary molars with 3 mesiobuccal root canals and to review the available literature on this anatomic variation. METHODS The first case described a nonsurgical root canal treatment of tooth 16 in a 29-yearold man with the aid of a dental operating microscope. In the second case, an extracted maxillary right first molar was scanned by a micro-computed tomographic system and reconstructed 3-dimensionally using modeling software. RESULTS In both cases, the mesiobuccal root had 3 canals (type 3-2 in case I and type 3-3 in case II), whereas the distobuccal and palatal roots had a single canal. The literature review showed that the overall incidence of 3-canaled mesiobuccal roots in maxillary molars ranged from 1.3%-2.4% and that the most common root canal configuration was type 3-2. CONCLUSIONS Clinicians should always anticipate the presence of extra canals in maxillary molars and use all the available tools to locate and treat these.

“…The current development of MCT technology reproduces voxel resolution up to 1 µm though around 10 - 30 µm resolution of MCT devices were used in root canal studies 17. The images obtained by MCT could be analyzed with various methods, including two-dimensional thin-slab minimum-intensity projection (TS-MinIP) technique and three-dimensional (3D) rendering techniques 18. The objective of this study was to discuss the protocols, advantages, and disadvantages of methodologies used for root canal morphology study and to suggest the 'Gold Standard' method for in-depth root canal morphology study.…”

A common failure in endodontic treatment of the permanent maxillary first molars is likely to be caused by an inability to locate, clean, and obturate the second mesiobuccal (MB) canals. Because of the importance of knowledge on these additional canals, there have been numerous studies which investigated the maxillary first molar MB root canal morphology using in vivo and laboratory methods. In this article, the protocols, advantages and disadvantages of various methodologies for in-depth study of maxillary first molar MB root canal morphology were discussed. Furthermore, newly identified configuration types for the establishment of new classification system were suggested based on two image reformatting techniques of micro-computed tomography, which can be useful as a further 'Gold Standard' method for in-depth morphological study of complex root canal systems.

“…[19] Although µCT has been compared to CBCT and reported to be more precise with up to 2 µm resolution,[2021] however, the limitations include amount of time required and its usage restricted to only ex vivo studies. [2223] Accuracy of CT imaging is well-documented. [24] Major advantages of CBCT over conventional CT scans include X-ray beam limitation,[25] rapid scan time[26] and effective dose reduction.…”

Aims:The study was aimed to acquire better understanding of C-shaped canal systems in mandibular second molar teeth through a clinical approach using sophisticated techniques such as surgical operating microscope and cone beam computed tomography (CBCT).Materials and Methods:A total of 42 extracted mandibular second molar teeth with fused roots and longitudinal grooves were collected randomly from native Indian population. Pulp chamber floors of all specimens were examined under surgical operating microscope and classified into four types (Min's method). Subsequently, samples were subjected to CBCT scan after insertion of K-files size #10 or 15 into each canal orifice and evaluated using the cross-sectional and 3-dimensional images in consultation with dental radiologist so as to obtain more accurate results. Minimum distance between the external root surface on the groove and initial file placed in the canal was also measured at different levels and statistically analyzed.Results:Out of 42 teeth, maximum number of samples (15) belonged to Type-II category. A total of 100 files were inserted in 86 orifices of various types of specimens. Evaluation of the CBCT scan images of the teeth revealed that a total of 21 canals were missing completely or partially at different levels. The mean values for the minimum thickness were highest at coronal followed by middle and apical third levels in all the categories. Lowest values were obtained for teeth with Type-III category at all three levels.Conclusions:The present study revealed anatomical variations of C-shaped canal system in mandibular second molars. The prognosis of such complex canal anatomies can be improved by simultaneous employment of modern techniques such as surgical operating microscope and CBCT.
