[Maxillary first molar with three mesiobuccal root canals: a case report]
1Dept. of Stomatology, Peking Union Medical College Hospital, Chinese Academy of Medical Science, Beijing 100730, China.
Summary
Three root canals found in the mesiobuccal root of a maxillary first molar is a rare dental anatomy variation. This case report details this unusual finding, noting the close proximity of the three canal orifices.
Area of Science:
- Endodontics
- Dental Anatomy
- Microscopic Dentistry
Background:
- The maxillary first molar typically exhibits a mesiobuccal root with two root canals.
- Anatomical variations in root canal morphology can impact endodontic treatment success.
- Understanding complex root canal systems is crucial for effective clinical practice.
Observation:
- A maxillary first molar presented with an unusual configuration of three root canals within the mesiobuccal root.
- The three canal orifices were located in close proximity, measuring 1.5 mm apart.
- All three canals were successfully negotiated and instrumented to within normal working length ranges.
Findings:
- This case confirms the rare occurrence of three root canals in a single mesiobuccal root of a maxillary first molar.
- The close spacing of the canal orifices presents a unique challenge for identification and treatment.
- Successful endodontic management was achieved despite the complex anatomy.
Implications:
- This finding highlights the importance of thorough radiographic and clinical examination to identify root canal anomalies.
- Clinicians should be prepared for and adept at managing complex root canal systems, including multiple canals in single roots.
- Further research into the prevalence and management of such variations can improve endodontic outcomes.

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 and...

01:21Tooth Anatomy
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 grinding food.
