C shaped canal: Variation and Recommendations

Root canal morphology is not uniform, variations of root canals are routinely encountered by endodontists making the root canal treatment more challenging. C shaped canal is a variation commonly encountered in mandibular second molars. The main identifying feature of such canals is presence of fins or webs interconnecting with the main canals. Such canal systems require meticulous mechanical and rigorous chemical preparation to ensure desired outcome of the treatment. Proper assessment of tooth morphology, preoperative radiograph along with consideration towards racial predilection will greatly help in accurate identification of such canals pre-operatively. This paper reports a case of C shaped canal in mandibular second molar diagnosed and treated taking all the precautions and adapting necessary modifications in the steps of conventional root canal treatment steps where required thus increasing the likelihood of success.

ABSTRACT Introduction The objective of this article is to highlight the importance of having a thorough knowledge about the root canal anatomy and the possibility of extra root/root canal. Materials and methods This case report presents the endodontic management of a left mandibular second molar with four roots and five canals. Results The clinical and radiographic diagnosis shows the existence of four roots and five canals (two in distobuccal root, one in distolingual root, one in mesiobuccal root, and one in mesiolingual root) in mandibular second molar. Conclusion Anatomic variation in the number of roots and root canals can occur in any tooth. Close examination of radiographs taken from different angles and careful evaluation of the internal anatomy of teeth is essential or else root canal treatment is likely to fail if extra roots or root canals are not detected.

Aim: The aim of this case report is to present a series of anatomical variations and endodontic treatments in four two-canal mandibular premolar teeth and three rooted three-canal maxillary second premolar teeth with root canal treatment indications identified via clinical and radiographic examinations. The success of root canal treatment is achieved with a thoroughly examined root canal morphology that has been accurately determined radiographically and clinically before adequate shaping, irrigation, and hermetic filling procedures. Root canals that are not found or not adequately disinfected can cause root canal treatment failure and complications, such as pain, swelling, or persistent fistula, also known as flare-up, after treatment. Canal variations in the teeth were detected via periapical radiographs during the root canal instrumentation stage. Methodology: The endodontic treatments of four two-canal mandibular premolar teeth and one triple-rooted three-canal maxillary second premolar with root canal treatment indications were described. Conclusion: To achieve full success in root canal treatment, anatomical variations should be examined in detail before and during treatment, and treatment should be completed with appropriate techniques.

It is of interest to compile available information on the root canal morphology of primary maxillary molars from known literature. The literature resources used to collect data include Medline/PubMed, The Cochrane Central Register of Clinical Trials, SIGLE and Science Direct. Data consists of type of population, number of teeth per study, number of root canals, canal length and type of root canal configuration. We used data from a total of 13 studies (951 primary maxillary molars). Maxillary molars (1st and 2nd) are dominant for two roots variant. The first molar the mean root length ranges from 7.9mm – 8.1mm. The second molar ranges from 7.2mm-8.5mm. Type I (explain in a phrase) canal morphology is the common variant in both the molars. Data shows that Root Canal morphology shows variations with the diagnostic aid (example micro CT) used and in different ethnic populations.

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.

Introduction. Predictable endodontic treatment depends on the dentist?s knowledge about root canal morphology and its possible anatomic variations. The majority of mandibular canines have one root and root canal, but 15% may have two canals and a smaller number may have two distinct roots. The following clinical reports describe endodontic treatment of mandibular canines with two roots and two root canals. Outline of Cases. Four clinical case reports are presented to exemplify anatomical variation in the human mandibular canine. Detailed analysis of the preoperative radiographs and careful examination of the pulp chamber floor detected the presence of two root canal orifices in all canines. Working length was determined with an electronic apex locator and biomechanical preparation was carried out by using engine driven BioRaCe Ni-Ti rotary instruments in a crown-down manner, followed by copious irrigation with 1% sodium hypochlorite. Definitive obturation was performed using cold lateral condensation with gutta-percha cones and Top Seal paste. The treatment outcome was evaluated using postoperative radiographs. Conclusion. Endodontists should be aware of anatomical variations of the treated teeth, and should never presume that canal systems are simple.

Introduction: It is important for a dental practitioner to have a clear understandingof the root canal morphology and its variations to perform successful root canal treatment.The inability to identify and adequately treat all canals of root canal system may contribute tothe failure of root canal treatment. Objectives: Clinically determine the frequency or numbersof root canals per tooth in the maxillary second molar teeth in the local population. Setting:Department of Operative Dentistry in Punjab Dental Hospital / de`Montmorency College ofDentistry, Lahore. Study Design: Randomized Control Trial. Study Period: 25th May 2013 to24th November 2013 (6 months). Results: This was a Cross sectional survey of 80 patients withsymptomatic irreversible pulpitis in maxillary second molar teeth in patients undergoing rootcanal treatment. The results showed that five (6.25%) patients had single root canal, seventeen(21.25%) patients had 2 root canals, forty (50%) patients had 3 root canals, seventeen (21.25%)patients had 4 root canals and one (1.25 %) patient had 5 root canals per tooth. In patientwith five canals, single root canal was present in distobuccal and palatal root each while threeroot canals were present in mesiobuccal root as MB-1, MB-2 and MB-3 canal. Conclusion:Local population have a lot of variations in root canal anatomy in second molar. So preclinicalknowledge can increase the success rate of root canal treatment.

Canal Morphology

Root canal treatment of tooth with aberrant root canal morphology is very challenging. So thorough knowledge of both the external and internal anatomy of teeth is an important aspect of root canal treatment. With the advancement in technology it is imperative to use modern diagnostic tools such as magnification devices, CBCT, microscopes, and RVG to confirm the presence of these aberrant configurations. However, in everyday endodontic practice, clinicians have to treat teeth with atypical configurations for root canal treatment to be successful. This case report presents the management of a mandibular first molar with six root canals, four in mesial and two in distal root, and also emphasizes the use and importance of Cone Beam Computed Tomography (CBCT) as a diagnostic tool in endodontics.
