Summary
Anatomical variations in teeth, like rare supplemental canals, can cause endodontic treatment failure if missed. Dentists must recognize these dental variations and use preoperative radiographs for successful root canal therapy.
Area of Science:
- Dentistry
- Endodontics
- Dental Anatomy
Background:
- Anatomical variations in human dentition are prevalent.
- Understanding these variations is crucial for successful endodontic treatment outcomes.
- Failure to identify rare canal anatomy can lead to treatment failure.
Purpose of the Study:
- To highlight the importance of recognizing anatomical variations in endodontic therapy.
- To present a case study illustrating treatment failure due to an undetected supplemental canal.
- To emphasize the role of preoperative radiographs in identifying complex root canal morphology.
Main Methods:
- Case report of endodontic therapy on a mandibular first molar.
- Analysis of intraoral periapical radiographs to identify root and canal anatomy.
- Evaluation of treatment outcome in relation to canal detection and obturation.
Main Results:
- A three-rooted mandibular first molar with an untreated supplemental canal was identified.
- The untreated canal led to persistent periapical radiolucency and periodontal space widening.
- Inability to locate and treat the rare canal resulted in endodontic treatment failure.
Conclusions:
- Awareness of dental anatomical variations, particularly in root canal morphology, is essential for endodontists.
- Preoperative radiographic interpretation is critical for detecting unusual canal systems.
- Thorough diagnosis and treatment planning, considering potential anatomical anomalies, improve endodontic success rates.

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...

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...
