RESUMO
Rationale: Multiple Calcifying Hyperplastic Dental Follicle (MCHDF) is an extremely rare condition and is characterised by multiple impacted permanent teeth, with enlarged dental follicles, containing calcifications. Cone-beam computed tomography (CBCT) is the ideal exam for the identification of this condition. Patient Concerns: The present study seeks to compare the behaviour of MCHDF in imaging exams of three clinical cases with their MCHDF imaging diagnoses, in which a change about tooth eruption was observed. Diagnosis: CBCT proved to be an important diagnostic tool for MCHDF, as it is able to identify these small calcifications, as well as measure the size of the follicle.Treatment Outcomes and Take. Away Lessons: With a consistent imaging diagnosis, less invasive treatments become a viable option for this condition, since functional and aesthetic involvement is common in these patients, who often tend to be quite young.
