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...

Background:

Segmental odontomaxillary dysplasia (SOD) is a rare developmental disorder of the maxilla.
It presents with variable clinical and radiological features, often mimicking other fibro-osseous lesions.
Typically diagnosed in early childhood, SOD involves unilateral alveolar process expansion, gingival enlargement, premolar absence, delayed eruption, and primary molar malformations.

Observation:

A rare case of SOD is described in a 19-year-old female.
The patient presented with pre-maxillary enlargement and an abnormal eruption pattern of anterior maxillary permanent teeth.
This marks the first reported instance of SOD occurring along the midline.

Findings:

Radiographic imaging revealed abnormal bony trabeculation in the affected maxilla.
Histopathologic examination confirmed the characteristic features of SOD.
The case aligns with previous reports but extends the known presentation of SOD to the midline.

Implications:

This case expands the spectrum of clinical presentations for Segmental Odontomaxillary Dysplasia.
Awareness of midline SOD is crucial for accurate diagnosis and management of facial asymmetry.
Further research into the etiology and management of SOD is warranted.
