Teeth

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...

Background:

Impacted teeth are a common dental issue, sometimes associated with pathological changes.
Dental follicles, remnants of tooth development, can undergo various hyperplastic or cystic transformations.
Calcifying hyperplastic dental follicles represent a specific, less common, developmental anomaly.

Observation:

A 31-year-old female presented with six impacted teeth.
Radiographic examination revealed cyst-like lesions surrounding the crowns of these impacted teeth.
The lesions exhibited mixed internal structures and well-defined cortical borders.

Findings:

Microscopic analysis of a dental follicle specimen showed collagenous connective tissue with calcified material.
Sparse epithelial islands were noted within the connective tissue.
The diagnosis was confirmed as multiple calcifying hyperplastic dental follicles.

Implications:

This case underscores the need for vigilant radiographic and microscopic evaluation of impacted teeth.
Understanding the histopathological features of calcifying hyperplastic dental follicles is crucial for accurate diagnosis.
Such findings may inform differential diagnoses for jaw lesions associated with impacted teeth.
