C-Shaped configuration of the canal in mandibular molars: A case report

The primary concern of this case report is to discuss and review the different etiological features of c shaped canals, with its incidence, along with anatomical features, diagnosis and management of the c shaped configuration of the canal in the molars of the mandibular arch. Literature revealed that c shaped canal configuration is slightly a different variation that has a predilection towards the racial and most of the times or most commonly is seen in mandibular molars that too most commonly in second molar of the mandibular arch. This morphology when present in the canal may posses difficulty in shaping of the canal, cleaning of the canal as well as debridement of the canal along with obturation of the canal. The one of the most common way in the management of this c shaped canal morphology is done by with the help of usage of rotary instruments and can also with the use of hand instruments that too assisted with sonics as well as ultrasonics.

ABSTRACT Objective: The aim of this retrospective study was to determine the root and canal morphology of the mandibular first and second permanent molars in a Turkish population using cone-beam computed tomography (CBCT). Materials and Methods: CBCT images of mandibular first (n = 966) and second molar (n = 1165) teeth from 850 Turkish patients were evaluated. The root canal configurations were classified according to the method of Vertucci. The data were analyzed by Pearson's Chi-square test. Results: The majority of mandibular molars were two rooted with three canals; however, three roots were identified in 0.05% of the first molars and 0.01% of the second molars, and 100% of the additional root canals were of type I configuration. Mesial roots had more complex canal systems with more than one canal, whereas most distal roots had a type I configuration. Conclusions: Within the limitations of this study, it can be concluded that CBCT scanning provides supplemental information about the root canal configurations of mandibular molars in a Turkish population. This study may help clinicians in the root canal treatment of mandibular molars.

A comprehensive knowledge of the root canal morphology and its variations is a basic requisite for the success of the endodontic treatment. Mandibular molars may present a third or additional root, which if located lingually is called radix entomolaris or bucally is referred as radix paramolaris. This case report shows an endodontic retreatment of a radix entomolaris and details some variations in the approach to guarantee a successful terapy.

ABSTRACT Aim C-shaped canal system is a seldom-found root canal anatomy which displays a challenge in all stages of endodontic treatment. According to the literature, this type of canal morphology is not a common finding in the mandibular first molar teeth. Background This case report presents endodontic management of a mandibular first molar with a C-shaped canal system. Case report Root canal system was cleaned and shaped by nickel-titanium (NiTi) rotary instruments combined with selfadjusting file (SAF). Obturation was performed using warm, vertical condensation combined with the injection of warm gutta-percha. Follow-up examination 12 months later showed that the tooth was asymptomatic. The radiological findings presented no signs of periapical pathology. Clinical significance The clinician must be aware of the occurence and complexity of C-shaped canals in mandibular first molar teeth to perform a successful root canal treatment. The supplementary use of SAF after application of rotary instruments in C-shaped root canals might be a promising approach in endodontic treatment of this type of canal morphology.

Root Canal Morphology

Introduction. This clinical case report presents the successful endodontic treatment of a maxillary second molar that has a mandibular molar-like anatomy with no palatal root and with each of its roots containing two separate root canals. Cone-beam computed tomography (CBCT) was used to confirm this unusual anatomy.Methods. A 34-year-old male patient was referred to the Department of Endodontics at Inonu University’s Faculty of Dentistry because of severe pain in his right maxillary second molar. Clinical and radiographic examinations identified unusual roots and root canals anatomy, and CBCT was planned in order to understand the nature of these variations. Cleaning and shaping procedures were performed using the crown down technique with Sybron Endo (Glendora, CA, USA) rotary instruments, and endodontic treatment was completed with gutta-percha cones and AH Plus resin sealers using the cold lateral compaction technique.Conclusions. The maxillary second molar exhibits aberrations and variations in terms of the numbers and configurations of its roots and root canals, and CBCT can be a useful imaging technique in endodontics.

ABSTRACT Variations in the root canal morphology are common and permanent maxillary molars are no exceptions. Permanent maxillary molars generally have three roots one palatal and two buccal. The incidence of a second palatal root is quite rare. This paper highlights the endodontic diagnosis and treatment of a permanent maxillary second molar having an additional palatal root using specialized diagnostic technique-spiral computed tomography.

Canal Morphology

Anatomical variations of the root canal system of mandibular molars are common and often present challenges for endodontic treatment. In some cases, an additional root is located in the distolingual, radix entomolaris (RE), or more rarely in the buccal, radix paramolaris (RP). This case report illustrates rare nonsurgical retreatment of the complex root canal morphology of a RP and demonstrates the utility of cone-beam computed tomography (CBCT) and 3D printing in managing such a case. Underscored is the need for clinicians to understand the possible variations of root canal morphology of mandibular molars and the role CBCT imaging can play in addition to periapical radiographs in order to successfully treat a tooth with radix paramolaris.

Canal Morphology

Background/Aim. For successful endodontic therapy, it is necessary to know root morphology. Therefore, the aim of our study was to analyze root canal morphology and root canal length of permanent molars in a Serbian population, using cone-beam computed tomography (CBCT). Methods. The study included a total of 305 maxillary molars, and 280 mandibular molars receiving cone-beam computed tomography examination and determined root numbers, canal morphology according to Vertucci classification, and canal lengths. Results were correlated with sex and tooth location in the jaw. Results. The mesiobuccal roots of first maxillary molars showed Vertucci type I in 45.7%, followed by type II in 29% of cases. For the second molar, Vertucci type I was found in 60.5% of cases in mesiobuccal canals. Palatal and distobuccal canals mostly presented Vertucci type I configuration. The mesial roots of mandibular molars had the highest frequency of two canals with Vertucci type IV as the most frequent for the first molar, and Vertucci type II for the second molar. Distal roots most commonly had one canal in both molars. Palatal canal length was the highest in maxillary first molars, with the mean value of 20.62 mm, while in second molars, the highest length value was for the mesiobuccal canal (20.09 mm). In both mandibular molars the mesial root canal was the longest one. Differences were found according to sex and tooth location in the jaw. Conclusion. Mesiobuccal roots of maxillary first molars had two canals; it was more frequently compared to second molars. Mesial roots of mandibular molars showed same frequency of two canals, and diversity in Vertucci types. Male patients tended to have higher complexity of root canal morphology compared to that of females. CBCT can improve understanding of the root canal morphology.

SummaryInferior alveolar nerve injury is one of the most serious complications of mandibular molar surgery and may lead to litigation for mal-practice. Entrapment of the inferior alveolar nerve to roots of an impacted mandibular molars is extremely rare. The aim of this case report is to stress the importance of tooth multi-sectioning with the use of magnification for the safe removal of a deeply impacted second molar with entrapment of the inferior alveolar nerve in its proximal root.
