C shaped canal in mandibular second molar

It is an aberrant morphology of mandibular second molar in which the horizontal cross section is in the form of a letter C, with canals which may or may not be separate. C-shaped canals in mandibular second molars are rarely found in Caucasians. This anatomy is much more common in Asians than in Caucasians.

In this type of configuration, the floor of the chamber is lower than normal. The access penetration is quite deep. You will also notice - if the tooth is vital - a large amount of bleeding.

Cooke and Cox were the first to describe a single-rooted mandibular second molar with a continuous slit connecting some or all of the canals. If sectioned horizontally through the main portion of the root, this slit had the shape of the letter “C. The purpose of this study was to investigate the anatomical features of C-shaped root canal system in mandibular second molars using micro-computed tomography (microCT). Fifty-eight extracted mandibular second molars with fused roots were collected from a native Chinese population. One of the most interesting configurations is known as a C-shaped mandibular second molar.

The C refers to distinct pulp chamber anatomy that contains one or multiple canals connected by a slit or fin (Figure 10). The occurrence of c ‑ shaped root canal configuration in mandibular first molar is rare. The present case has an unusual C - shaped root canal configuration for both the appearances of the canal orifices and the configuration along the roots.

C - shaped canals in mandibular second molars are rarely found in Caucasians. Although its most common configuration is two roots and three canals , the mandibular second molar may have many different combinations. They have a relatively high prevalence in mandibular second molars of Chinese and Lebanese populations. Conclusion There was high prevalence of C‐shaped root canals in the mandibular second molars of Koreans. C‐shaped canals having semicolon and continuous shapes at the canal orifice have a high possibility of being divided into two or three canals in the apical region.

Careful assessment of preoperative radiograph is a key step for its subsequent management, and this assessment might impact greatly on the treatment outcomes. Of particular interest is the canal configuration of the mandibular second molar as a great deal of variations can occur. Melton DS, Krell KV and Fuller MW.

Diagnosis, Classification, and Frequency of C - Shaped Canals in Mandibular Second Molars in the Lebanese Population Gaby Y. Hadda DC DESE, Walid B. Nehme, DC DESE, and Hani F. The C - shaped root canal configuration is an anatomical variation of root fusion and a type of taurodontism commonly seen in the mandibular second molar with prevalence ranging from 2. In this configuration, the root canals are connected by slit or web with varying anatomy along the root length which makes. Forty-four extracted mandibular second molars with C - shaped roots were collected from a Chinese population. Hence, a C - shaped root in a mandibular second molar may present radiographically as a single-fused root or as two distinct roots with a communication.

The radiograph may also reveal a large and deep pulp chamber, usually found in C - shaped molars. More recently, C - shaped (gutter- shaped ) root and canal configurations have been reported in different populations. On examination, cleaning and shaping completed by crown commonly observed in single rooted the teeth were carious and sensitive to down method.

The canal systems varied considerably in their anatomical configuration. The pulp chamber has a single ribbon-shaped orifice with a 1° arc from the distal to mesial canal (4). The floor of the pulp chamber is deep and has an unusual anatomical appearance (3).

C shape canal presents an extensive complex system and is mostly seen in mandibular second molars. Aim To investigate the incidence and morphology of C ‐ shaped root canals of the mandibular second molar in a Korean population. Methodology Through clinical observation, randomly selected 2mandibular second molars of Korean patients were accessed and evaluated after taking radiographs for determination of working length.
