1800 pre-made cone beam computed tomograms (CBCT) were examined, of which 202 CBCT were selected. It was revealed that a prevalence of three-rooted mandibular first molar was 2,5 %, second molars – 4,5 %. First molar supernumerary root was always distolingual root (radix entomolaris). Second molar supernumerary root was distolingual root in 2,5 % (radix entomolaris), in 2 % mesialbuccal root (radix paramolaris)., The prevalence of double-root in the mandibular first premolar was 2 %, in the second premolar was 1 %, in the mandibular canines was 5 %, the bifurcation was located in the apical and middle third root canals of canine and premolar, which makes endodontic treatment of such teeth as difficult as possible.

Objectives: Cone-Beam Computed Tomography is an alternative imaging technique which has been recently introduced in the field of Oral & Maxillofacial Radiology. It has rapidly gained great popularity among clinicians due to its ability to detect lesions and defects of the orofacial region and provide three-dimensional information about them. In the field of Endodontics, CBCT can be a useful tool to reveal tooth morphology irregularities, additional root canals and vertical root fractures. The objective of this study is to evaluate the root and root canal morphology of the maxillary permanent molars in Greek population using Cone-Beam Computed Tomography.Materials and Methods:273 cone-beam computed tomography (CBCT) images were examined. The number of roots and root canals of the first and second maxillary molars were evaluated. Root canal configuration was classified according to Weine’s classification by two independent examiners and statistical analysis was performed.Results:A total of 812 molars (410 first and 402 second ones) were evaluated. The vast majority of both first and second molars had three roots (89.26% and 85.07%, respectively). Most first molars had four canals, while most second molars had three. In the mesiobuccal roots, one foramen was recorded in 80.91% of all teeth. Other rare morphologic variations were also found, such as fusion of a maxillary second molar with a supernumerary tooth.Conclusion:Within the limitations of this study, it can be concluded that more attention should be given to the detection of additional canals during root canal treatment in maxillary permanent molars. Towards this effort, CBCT can provide the clinician with supplemental information about the different root canal configurations for successful Root Canal Treatment.

Maxillary molars present variable root canal and root morphologies. This report describes the endodontic management of two cases of midbuccal canals found in maxillary molars. Midbuccal canals were present in a maxillary first molar with a single buccal root (Case 1), and in a maxillary second molar with three buccal roots (Case 2). An assessment of the internal configuration of these teeth was performed using cone-beam computed tomography (CBCT). Magnification with a dental operating microscope, surgical loupes, and the use of an endodontic explorer enabled the identification of the midbuccal canal orifices. The root canals in both cases were chemomechanically prepared and filled. Postobturation radiographic images revealed four (one midbuccal, two mesiobuccal and one palatal) and five (one midbuccal, two mesiobuccal, one distobuccal and one palatal) root canals, which were filled in Cases 1 and 2, respectively. Complex canal configurations of maxillary molars including the presence of midbuccal canals were presented. CBCT was a valuable tool in this diagnosis, as it provided a precise description of these unusual anatomical variations.

ABSTRACT Introduction Taurodontism is a morpho-anatomic variation in tooth anatomy that rarely affects mandibular premolars. Literature is replete with mandibular first premolars presenting atypical additional root canals, but concurrent presence of three roots and taurodontism is exceptional. Materials and methods This case report describes the successful endodontic diagnosis and management of a rare case of taurodontism in a mandibular first premolar with chronic apical periodontitis. Cone beam computed tomography (CBCT) facilitated the diagnosis of three roots and root canals associated with concurrent taurodontism. The taurodont premolar required exceptional and diligent care in each segment of endodontic treatment for the complex root canal system. Results Taurodontism-affected premolars present with challenges in endodontic therapy as they have apically displaced pulp chambers with limited width. Cone beam computed tomography and dental operating microscope can facilitate evaluation for teeth with such complex anatomy and their successful endodontic management.

Variations of root canal systems need not always be in the form of extra canals. Clinicians should be aware that there is a possibility of existence of fewer numbers of roots and root canals than normal, which presents varied canal anatomy and poses a challenge to the clinician's expertise. This case report deals with the management of an unusual case of C-shaped canal in mandibular second molar. Cone-beam computed tomography (CBCT) was employed to conrm the extension of the unusual anatomy. 3-D Obturation done with the help of thermoplastic obturation unit.

Abstract Background: This study aimed to identify and characterize root and canal morphology and the prevalence of C-shaped canals of mandibular second molars (MSMs) in a Yemeni population using cone-beam computed tomography (CBCT). Methods: CBCT images of 500 right and left MSMs with mature roots were taken from 250 Yemeni individuals and analyzed for the following features: number of roots, total number of canals orifices within the tooth and number of canals orifices in each root, type of roots, either fused or separated, shape of root in cross section, type of canal configuration in each root, presence of C-shaped canal, and primary variations in the morphology of root and canal systems. Results: Molars with separated two roots predominated (89.6%), fused two roots were 9%, separated three roots were 0.6% and one root MSMs were 0.8%. Molars with three canals orifices were the most common. Mesial root was mainly ribbon-shaped (60.5%) and distal root was mainly kidney-shaped (50.7%). Type II and Type I canal configurations were the most frequent in mesial root (56.9%) and distal root (91.3%), respectively. C-shaped canals were found in 9%. Six variants were found with variant 3 was the most common (71%). Conclusions: Yemeni permanent MSMs have mainly two separated roots. Mesial root is mostly ribbon-shaped and distal root is mainly kidney-shaped. Vertucci type II and I canal configurations showed the higher incidence in mesial and distal roots, respectively. C-shaped canals were found in 9%. Keywords: Cone-beam computed tomography, C-shaped canal, mandibular second molar, morphology, root canal, Yemen

Permanent mandibular second molars usually show two roots, one mesial and the other distal root with four root canals (two mesial and two distal canals). Variation in root number and canal morphology rarely occur in these teeth. Cone Beam Computed Tomography is a new advent in the diagnostic field which provides three dimensional clear picture of the root/canal. The present article describes the endodontic management of permanent mandibular left second molar with Vertucci II canal configuration using cone beam computed tomography.

Endodontic treatment of mandibular molars is challenging because of variable root canal morphology. The nonsurgical endodontic management of a mandibular first molar presenting an independent middle mesial canal is reported. After coronal access, additional clinical inspection of the mesial canals’ orifices and their interconnecting groove using an endodontic explorer and 4.5× loupes enabled the identification of the middle mesial canal orifice. All root canals were chemomechanically prepared and filled. The tooth was asymptomatic and functional after 4 years of followup. Cone beam computed tomography (CBCT) images revealed normal periapical status and three-dimensional (3D) anatomical aspects of the root canal system.

ABSTRACT Objective: To investigate the anatomic symmetry of maxillary and mandibular posteriors in Indian subpopulation using cone beam computed tomography (CBCT). Materials and Methods: CBCT images of 246 patients that had at least one noncarious, posterior tooth free of restorations in each quadrant were enrolled for retrospective analysis. A total of 3015 teeth (811 maxillary premolars, 845 mandibular premolars, 738 maxillary molars, and 621 mandibular molars) were analyzed for number of roots and root canals, canal morphology and anatomic symmetry, and concurrent types between the maxilla and mandible. Results: There was no difference in the percentage of symmetry for maxillary first (81.5%) and second (81.5%) premolars. Mandibular second premolars (98.3%) exhibited greater symmetry than mandibular first premolars (96.1%). First molars (77.5% and 82.1%) showed greater symmetry than second molars (70.8% and 78.6%), in both maxillary and mandibular arches, respectively. The most common anatomy observed were: maxillary first premolars – 2 roots with 2 canals, maxillary second premolars – 1 root with 2 canals, mandibular first and second premolars – 1 root with 1 canal, maxillary first and second molars – 3 roots with 4 canals, and mandibular first and second molars – 2 roots with 3 canals. When compared with any other teeth, maximum asymmetry was observed in maxillary second molar (29.2%). Conclusion: The percentage of symmetry observed in the present study varied from 70% to 98% with least percentage of symmetry in maxillary second molars. These data should alert the clinicians while treating homonymous teeth of the same patient.
