Abstract:

The aim of this study was to evaluate the clinical and radiological findings of a hypoesthesia case due to dentigerous cyst in mandible. 60-year-old male patient referred to our clinic with the complaint of numbness in the right lower lip for a month. Panoramic radiography and cone beam computed tomography were performed. The patient was treated by the surgical excision of the radiologically determined impacted right mandibular third molar teeth and the surrounding injury. Panoramic radiograph revealed that the follicular space size of the impacted third molar teeth in right mandible was about 5 mm. Cone beam computed tomography confirmed a well-defined, unilocular radiolucency associated with the crown of the impacted tooth, and a close anatomical relationship between the tooth and the mandibular canal, as well as between the cyst and the mandibular canal. Histopathological evaluation revealed dentigerous cyst. After the treatment, hypoesthesia is resolved within 6 months. The presence of impacted teeth represented close anatomical localization to the mandibular canal should be thought as a reason of hypoesthesia.
