Abstract

This report describes a 31-year-old female patient with six impacted teeth. The crowns of the impacted teeth were surrounded with cyst-like lesions with a mixed internal structure and well-defined cortical borders. Microscopic examination of the specimen obtained from the follicle of the left mandibular third molar tooth revealed loose to moderately dense collagenous connective tissue with abundant calcified material and sparse epithelial islands. A diagnosis of multiple calcifying hyperplastic dental follicles was made.

  Fig. 1 An intraoral photograph reveals missing teeth, diastemata, and buccolingual expansion of the alveolar bone.

  Fig. 2 A cropped panoramic radiograph demonstrates six impacted teeth, crowns surrounded with cystlike lesions having mixed internal structure, and well-defined cortical borders.

  Fig. 3 A. An axial computed tomography scan shows rounded hypodense lesions containing hyperdense foci with well-defined borders, associated with the crowns of mandibular molar teeth. B. An axial computed tomography scan reveals the mixed internal structure of the maxillary lesions.

• 

  Fig. 4 A. Microscopic examination shows type 1 calcifications arranged in whorled structures. Liesegang ring-like structures are prominent (arrows) (H&E stain, 200×). B. Type II calcifications (arrowhead) and an odontogenic epithelial rest (arrow) in a collagenized dental follicle are seen (H&E stain, 200×).

  Fig. 5 A cropped panoramic radiograph taken five years later shows a focal increase in the radiopacity associated with the crown of the right mandibular third molar tooth and a small radiopaque prominence associated with the inferomedial aspect of the follicle of the left mandibular third molar tooth. The hyperplastic follicles reveal an irregular contour.
