Summary
This case study details a rare mandibular first molar with six root canals, featuring two mesial and four distal canals within two separate distal roots. The findings highlight the critical importance of thorough canal exploration in endodontic treatments.
Area of Science:
- Dentistry
- Endodontics
- Dental Anatomy
Background:
- Mandibular first molars typically exhibit predictable root canal anatomy.
- Anatomic variations in root canal systems can complicate endodontic treatment.
- Identifying all root canals is crucial for successful root canal therapy.
Observation:
- A mandibular first molar presented with an unusual number of root canals.
- The molar had a total of six canals: two mesial and four distal canals.
- The four distal canals were located within two distinct distal roots.
Findings:
- The root canals were instrumented using K-files.
- Irrigation was performed with sodium hypochlorite (NaOCl) and normal saline.
- Lateral condensation with gutta-percha and AH26 sealer was used for canal obturation.
Implications:
- This case demonstrates an extremely rare anatomic variation in mandibular molars.
- It underscores the necessity for clinicians to meticulously search for accessory canals.
- Awareness of such variations can improve diagnostic accuracy and treatment outcomes in endodontics.

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.

01:15Teeth
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...
