Summary
A rare erupted complex composite odontoma (CO) in a Saudi male
Area of Science:
- Dentistry
- Oral Pathology
- Developmental Biology
Background:
- Odontomas are benign odontogenic tumors representing malformations of dental tissues.
- Complex composite odontomas (CO) arise from disorganized dental component development.
- Erupted COs are exceptionally rare, with few documented cases.
Purpose of the Study:
- To report a rare case of an erupted complex composite odontoma in the mandibular body.
- To highlight the successful management and favorable prognosis of such lesions.
Main Methods:
- Surgical excision of the odontoma under local anesthesia.
- Histopathological examination for definitive diagnosis.
- Clinical monitoring of the associated impacted tooth.
Main Results:
- A complex composite odontoma was surgically removed from the left mandibular body of a 17-year-old male.
- Histopathology confirmed the diagnosis of CO.
- The impacted second molar erupted naturally within six months post-surgery.
Conclusions:
- Erupted complex composite odontomas in the mandibular body are exceedingly rare.
- Early diagnosis and timely surgical intervention lead to favorable outcomes.
- Conservative management of associated impacted teeth can be successful.

Tooth 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.

Teeth
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...

Oral Cavity
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
