Diagnosis and treatment of maxillary molar with abnormality
Kkot-Byeol Bae,이빈나,장훈상,황인남,오원만,황윤찬 조선대학교 치의학연구원 2022 Oral Biology Research (Oral Biol Res) Vol.46 No.4
Endodontic treatment of an abnormally shaped tooth is complicated by irregular tooth morphology. Furthermore, root canal fusions are known to occur in abnormal teeth. The placement of canal orifices is unusual and due to their depth, they are sometimes invisible to the naked eye. As a result of the difficulty in instrumentations and obturation, root canal treatment of teeth with an abnormality is difficult. When performing root canal treatment on abnormal teeth, complex anatomic variations of the root canal system should be investigated as thoroughly as possible. Cone-beam computed tomography is an effective method for assessing the morphology of the root canal by visualizing the canal of the tooth. The case reports that follow each describe a case of root canal treatment in a maxillary molar with an abnormality.
Surgical treatment of mandibular first premolar with radicular groove: periradicular microsurgery
최유리나,Sue A Kim,Kkot Byeol Bae,Hoon-Sang Chang 조선대학교 치의학연구원 2024 Oral Biology Research (Oral Biol Res) Vol.48 No.1
This study aimed to report the results of a successful periradicular microsurgery on a mandibular first premolar with a radicular groove. A 38-year-old female reported a sinus tract on her buccal gingiva which was radiographically traced to the middle third of the mesial side of the root of her mandibular right first premolar (#44). A radicular groove and an accessory canal in the middle of the radicular groove were found using cone-beam computed tomography. After endodontic treatment, the sinus tract did not disappear; thus, periradicular microsurgery was performed. The radicular groove and the accessory canal were prepared and filled with fastsetting MTA without resectioning the root apex. After 3 weeks, the sinus tract disappeared, and complete healing was revealed on the periapical radiograph at a 5-month follow-up. Therefore, periradicular microsurgery is recommended in mandibular first premolars with radicular grooves on the accessible mesial side of the root.
