Management Of C- Shaped Canal ? A Case Report.

The root canal morphology always poses a challenge to the clinician especially the C shaped canal. Proper identification, correct negotiation, suitable cleaning and shaping technique, adequate utility of diagnostic aids are the key factors to successfully restore this aberrant canal configuration. Along with this the clinician should also be aware of the existence of such variations that challenges his expertise. This case report deals with the management of an unusual case of C-shaped canal in mandibular molar with two buccally fused roots. Computed tomography (CT) was employed to confirm the existence of this unusual anatomy. Rotary endodontic instruments were utilized to ensure complete cleaning of the canal system. Use of diagnostic aids like CT, CBCT, improved magnification with dental operating microscope, and the use of novel file systems ensure success.

A thorough knowledge of tooth morphology, careful interpretation of angled radiographs, proper access preparation and a detailed exploration of the interior of the tooth are essential prerequisites for a successful treatment outcome1. C shaped canals are an uncommon variation, which can pose a challenge to even the experienced clinician during root canal negotiation. The name comes from the appearance of the pulp chamber floor when viewed from above. Some or all of the canal orifices are joined in the form of a groove or isthmus with a shape of the letter C. It presents with variation in both number as well as location of the root canals. The C shaped canal is special feature of some lower second molars. Approximately 1% of lower second molars have C-shaped canals. It is rather commonly found in the mandibular second molars, it may also occur in mandibular premolars, maxillary molars and mandibular third molars. It is very important to identify the canal configuration early so as to aid the clinician in proper negotiation, preparation and thus prevent irreparable damage to the tooth structure. - See more at:
