C shaped canal

C-shaped canals normally have three canals. This connection - or fin- holds tremendous amounts of tissue. Sometimes, all three canals are connected in a horseshoe type ring.


The ML canal usually is separate. A true C is less common than the regular C and often is seen in third molars.

You should instrument all canals individually. The intricacies present in this variation of canal morphology can pose a challenge to the clinician during negotiation, debridement and obturation. Although relieving the patient’s pain and eliminating swelling is of primary concern, it is always a great feeling to have patients witness the healing process through radiographic follow-up. 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. Dentin bridges impede such passage in other configurations.


A) With two separate canals.

B) With three separate canals. The occurrence of c ‑ shaped root canal configuration in mandibular first molar is rare. The main feature of this variation is the presence of a fin or web connecting the individual root canals to form a letter ‘ C ’ shape at the root canal orifice.


In this configuration, the root canals are connected by slit or web with varying anatomy along the root length which makes thorough debridement obstacle for the clinician. The main identifying feature of such canals is presence of fins or webs interconnecting with the main canals. C shaped canal is a variation commonly encountered in mandibular second molars.


To perform a systematic review of anatomical studies using cone beam computed tomography (CBCT) to assess the influence of demographic factors (age, gender and geographic region) on the prevalence of C‐shaped canal anatomy in maxillary molars, mandibular premolars and molars. A thorough understanding of root canal anatomy is of paramount importance in the field of dentistry. In a transverse section, the shape of this canal is observed as the letter C. The presence of a fin or web connecting the individual root canals is another anatomic feature. On examination, cleaning and shaping completed by crown commonly observed in single rooted the teeth were carious and sensitive to down method.


Studies report the frequency between 2. One of the contributing factors that masks more. Variations of root canal anatomy between races is reported in many studies. This canal type is also known as a true C - shape.

C - shaped complaint of sharp pain right mandibular first one. This fusion remains irregular and the two roots stay connected by an interradicular ribbon. Authors have been credited for the individual posts where they are.


It is found when fusion of either the buccal or lingual aspect of the mesial and distal roots occurs. Fusion may remain irregular throughout the root, and interradicular ribbon shape communication can be seen. Endodontic Management of C Shaped canal configuration in mandibular second molars : A report for two cases.


Author(s): Moinuddin M, Doddi L, Ramachandruni N, Prasa Rachakonda H. Unusual canal morphologies hamper the success rate of endodontic treatment. Radiographically, the tooth had a normal morphological appearance with distinct and separate roots.
