Aim:
To present a clinical case report in a mandibular first molar with a middle distal canal, along with a review of the literature.
Summary:
With the use of magnification, either by microscopes or by loupes, there is an increasing possibility of detecting additional canals. The present case describes root canal treatment in a mandibular first molar with two roots and a Sert and Bayirli Type XVIII canal configuration in the distal root. The presence of a three canals in the distal root of mandibular first molars has been reported to have an incidence of 0.2-3%.
Key Learning Points:
* Clinicians should be aware of the variable root canal anatomy in the distal root of mandibular first molars. * Use of magnification helps to identify and locate additional root canals. * Three root canals in the distal root of mandibular first molar teeth might occur.
