Summary
This case study details the rare finding of five canals in two symmetrical maxillary first molars. The distobuccal root of each tooth contained two separate canals, a significant dental anatomy variation.
Area of Science:
- Endodontics
- Dental Anatomy
- Radiology
Background:
- This study focuses on the endodontic treatment of complex root canal anatomy.
- It addresses the diagnosis and management of variations in maxillary first molars.
Observation:
- A patient presented with pain in tooth #16, a maxillary first molar.
- During endodontic treatment, tooth #16 revealed an unusual fifth canal in its distobuccal root.
- Tooth #26, also a maxillary first molar, showed similar anatomical complexity.
Findings:
- Detailed examination confirmed the presence of an additional canal within the distobuccal root of both maxillary first molars.
- Electronic apex locator and working radiographs verified the complex canal morphology.
- Necrosis was diagnosed in the severely decayed tooth #26.
Implications:
- This finding highlights the importance of thorough exploration in endodontic diagnosis.
- Understanding such anatomical variations is crucial for successful root canal treatment.
- It emphasizes the need for advanced imaging and diagnostic tools in complex endodontic cases.

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...

01:27Cranial Bones: Lateral View
6.8K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
