Summary
Mandibular premolars rarely have extra canals, but clinicians must consider this possibility during root canal treatment. This case series highlights three instances of mandibular premolars with three canals, emphasizing the need for thorough morphological knowledge.
Area of Science:
- Endodontics
- Dental anatomy
Background:
- Root canal morphology in mandibular premolars typically involves one root and one or two canals.
- Variations in canal configuration can complicate endodontic treatment.
Observation:
- This case series reports on three patients with mandibular premolars exhibiting an unusual anatomy.
- Each affected premolar presented with a single root but contained three distinct root canals.
Findings:
- The study identified a rare occurrence of three canals within a single root of mandibular premolars.
- This anatomical variation deviates from the commonly expected morphology.
Implications:
- Accurate diagnosis and treatment planning in endodontics require a comprehensive understanding of root canal anatomical variations.
- Awareness of such anomalies can improve clinicians' success rates in managing complex root canal treatments.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
