Summary
An erupted odontoma, a benign jaw tumor, delayed a child's first molar eruption. Surgical removal allowed the impacted molar to erupt, highlighting the need for radiographic examination of delayed tooth eruption.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
- Pediatric Dentistry
Background:
- Odontomas are benign odontogenic tumors, typically developing within the jawbone.
- Eruption of odontomas into the oral cavity is a rare clinical occurrence.
- Delayed tooth eruption can significantly impact dental development and occlusion.
Observation:
- A 10-year-old girl presented with delayed eruption of the right maxillary first molar.
- A hard, tooth-like tissue was visible due to inflammation, later identified as an erupted odontoma.
- Radiography confirmed a 1 cm radiopaque mass near the unerupted first molar, displacing its developing germ.
Findings:
- Surgical extraction of the erupted odontoma was performed.
- The maxillary first molar erupted spontaneously approximately five months after odontoma removal.
- The permanent tooth germ, though displaced, retained sufficient eruptive potential.
Implications:
- This case underscores the importance of radiographic evaluation for significantly delayed tooth eruption.
- Early detection and removal of physical obstructions like erupted odontomas can prevent complications.
- Routine dental checkups may facilitate earlier identification of delayed eruption and underlying causes.

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...

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...
