Manzoor, Sharma, Bansal, Popat, and Manzoor: C-Shaped configuration of the canal in mandibular molars: A case report


Introduction

A clinician should or must be having a thorough knowledge of root canal anatomy and configuration of the morphology of the root canal along with different types of variations that are required for attaining or achieving the clinical success in the root canal therapy, that should only be done if the clinician is having proper knowledge of diagnosis with a good treatment planning and a good clinical experience. This type of c shaped variation in morphology present with variation in number as well as the location of the canal from the coronal portion of the crown to the apical third of the root.1, 2, 3, 4 Out of all one variation of the root canal system is the c shaped configuration of the canal in the mandibular second molar. It was known as c shaped morphology because of the presence of c – shaped cross sectional and anatomical configuration of the root along with the root canal. 5

Case Report

A female patient of 39 years reported to the department of conservative and endodontics, Jaipur dental college, rajasthan and having a chief complaint of pain that is continuously present in the lower left posterior region of the mandible. After history was taken it was revealed that there was an intermittent pain which is present in the left mandibular first molar from the last 2 months, and this pain has showed increased intensity from the last three days. Patient also give history of subjective symptoms that includes sensitivity to any thermal stimuli along with increased intensity of the pain. Patient shows non contributory medical history.

The radiographs which were taken prior to the starting of the procedure showed that there was a radiolucency that was approaching to the pulpal space along with the periodontal ligament space has been widened adjacent to the apex of the root. From all the diagnostic tools that include sensibility tests, clinical examination as well as radiographical examination confirmed the case as of irreversible pulpitis that is symptomatic along with symptomatic apical periodontitis. In this case we approached the case with normal non surgical endodontic treatment plan. Whole of the treatment modality and treatment plan was thoroughly explained to the patient and a written consent was obtained from the patient. The procedure was started with the access opening was done under the application of the rubber dam which is followed by  working length determination using k 10 no k file , biomechanical preparation was done upto 20/6% rotary files followed by proper irrigation than obturation was done.

Discussion

By the chronological age it was noted that the mandibular first molar do erupts in to the oral cavity by the age of 6 to 7 yearsand the apical closure of the root was completed by 8 to 9 years. The completion of the root canal differentiation commences by three to six years after the completion of the root.6 any sort of disturbance due to any reason like trauma will result in variation sin the anatomy of the root canal. Sabala et al7 revealed that when the aberration is rarer, there will be higher probability of it being bilateral. In this clinical case the mandibular posteror tooth of the contralateral arch is extracted and therefore the anatomical morphology could not be able to determine.

Conclusion

It was concluded that the c shaped configuration of the root canal is found to be havaing ethnic predilection along with a higher chances of prevalence rate in thesecond molar of the mandibular arch. So one should understand the anatomical morphology of the tooth along with its variations will surely helps out the dentist to manage these sort of cases successfully.
