Author Year Sample Study Findings and conclusion
JojoKottoor et al. [16] 2010 Case report Maxillary First Molar with Seven Root Canals Diagnosed with Cone-Beam Computed Tomography Scanning Unusual morphology was confirmed with the help of cone beam computerized tomography (CBCT) scans
Zheng et al. [17] 2011 608 teeth Evaluation of the anatomical features of C-shaped
canal systems in Chinese mandibular second molars by
cone-beam computed tomography (CBCT).
CBCT is a clinically useful tool in the assessment of additional distolingual  root and “C” shaped canals
Zhang et al. [18] 2011 389 teeth Use of cone beam computed tomography to evaluate root and canal morphology of mandibular molars in Chinese  individuals CBCT is an effective tool for the detection of additional distolingual root and C-shaped root/canals, and it is a valuable aid for dentists providing root canal treatment.
Mathrene et al. [19] 2008 72 extracted teeth Comparison of CBCT and radiography in identifying the canal anatomy CBCT identified more canals which were missed by radiographs
Tomoatsu Kaneko [20] 2011 Case report Non-surgical endodontic treatment of dens invaginatus with the aid of (CBCT). CBCT greatly helped the decision of avoiding further intervention that could have been difficult to negotiate.
Abella et al. [21] 2011 Case report Managing severe curvature of radix entomolaris: three-dimensional analysis with cone beam computed tomography CBCT provided more accurate information in terms of RE inclination and root canal curvature before commencing root canal treatment.
Je´roˆme Michetti et al. [22] 2010 90 teeth Validation of Cone Beam Computed Tomography as a Tool to Explore Root Canal Anatomy Strong to very strong correlation was found between the data acquired by using CBCT and histology
Patel S [23] 2010 Case report The use of cone beam computed tomography in the conservative management of dens invaginatus The true nature of dens invaginatus cannot always be estimated from conventional radiographs.  Cone beam computed tomography is a useful diagnostic tool in the management of dens invaginatus.
Kottoor J et al. [24] 2011 Case report Four-rooted maxillary first molar having C-shaped palatal root canal morphology evaluated using cone-beam computerized tomography The evaluation of CBCT images can result in better understanding of root canal anatomy, which enables the clinician to investigate the root canal system and to clean, shape, and obturate it more effectively.
Kottoor J [25] 2010 Case report Endodontic management of a maxillary first molar with eight root canals evaluated using cone-beam computed tomography scanning The use of CBCT imaging in endodontically challenging cases can facilitate a better understanding of the complex root canal anatomy, which ultimately enables the clinician to explore the root canal system and clean, shape, and obturate it more efficiently.
Vier-Pelisser FV et al. [26] 2012 Case report Use of cone beam computed tomography in the diagnosis, planning and follow up of a type III dens invaginatus case. CBCT may aid the diagnosis as well as the management plan and follow-up of teeth with this developmental anomaly.
La SH et al. [27] 2010 Case report Identification of independent middle mesial canal in mandibular first molar using cone-beam computed tomography imaging. This case report highlights the usefulness of CBCT imaging for accurate diagnosis and management of the unusual canal morphology.
Bernardes RA et al. [28] 2012 34 teeth Comparative study of cone beam computed tomography and intraoral periapical radiographs in diagnosis of lingual-simulated external root resorptions. Cone beam computed tomography showed better diagnostic ability compared with intraoral radiography, regardless of the tooth or the dimensions of the resorption evaluated.
Reis AG [29] 2013 100 patients, 343 teeth Correlating second canal in mesiobuccal root of maxillary molars with root third and patient age The prevalence of MB2 canals was found to decrease as the root canal approaches the apical third and as age increases. CBCT scanning proved effective in mapping MB2 canals present in different thirds of the root.
Guerrero ME [30] 2013 256 Patients Comparison of panoramic radiography and CBCT to predict postoperative outcome after wisdom tooth removal This study concluded that, CBCT was not better than panoramic radiography in predicting postoperative complications for moderate-risk cases of impacted third mandibular molars. Nonetheless, a CBCT buccolingualview can accurately confirm the number of roots and root morphology of the third molar better than PA
Vizzotto MB[31] 2013 89 maxillary molar teeth CBCT for the assessment of second mesiobuccal (MB2) canals in maxillary molar teeth: effect of voxel size and presence of root filling. CBCT was associated with higher mean values of specificity and sensibility than radiographic examination for the detection of MB2 canals. When endodontic retreatment is necessary removal of the root filling prior to the CBCT examination eliminates artifacts.
