USE OF THREE-DIMENSIONAL COMPUTED TOMOGRAPHY AND MICROSCOPE IN THE MANAGEMENT OF A PERSISTENT PERIAPICAL LESION

抄録

A 30-year-old female patient presented with swelling and discomfort in the region of the upper right incisors. She underwent root canal treatment on #11 and #12 at a private dental clinic; however, the condition persisted. Cone-beam computed tomography (CT) was performed for proper diagnosis. CT showed resorption of the upper labial and lingual cortical bone. The patient was referred to the hospital attached to Nihon University School of Dentistry at Matsudo. The teeth were root canal treated under a microscope. Calcium hydroxide was applied to the resorbed apical foramen. Gradually, the patient’s symptoms disappeared, and the apical foramen calcified. Finally, cortical bone was recovered, and the periapical lesion disappeared. The conditions were confirmed using three-dimensional (3D) CT. CT and microscope are useful for endodontic therapy, especially in persistent periapical lesions.
