External cervical resorption case report and a brief review of literature
A 23-year-old female patient reported to the Department of Periodontics in Thai Moogambigai Dental College with the chief complaint of pain in the left upper-front teeth region for the past 2 months, seeking treatment. On clinical examination, the tooth was found to be non-vital, and grade 1 mobility was observed. Temporary splinting was done from 13 to 23 to stabilize the tooth. Patient was then referred to conservative department to check the non-vitality and further management in relation to 21. The tooth was found to be non-vital and root canal treatment was performed. The patient was then referred back to Department of Periodontics for management of periodontal pocket of 10 mm in relation to distal aspect of 21. Radiographic examination revealed vertical bone loss and external tooth resorption on the distal aspect of 21 [Figures and ].\nOn subsequent appointment, scaling and root planning was done, and patient was reviewed after 2 weeks. On reviewing the patient, the pocket still persisted in distal aspect of 21 region. Therefore, flap surgery was planned and local anesthesia (2% lignocaine 1:80,000 adrenaline) was given. Sulcular incision was given and the flap was raised []. On raising the flap, there was resorption in the mesisl and distal aspect of 21 [Figures and ] and combined two-walled defect in the coronal aspect and three-walled defect in the apical region. The defect was then debrided, resorption was filled with MTA [], and covered with resin-modified glass ionomer filling material (RMGIC) [Figures and ] in a sandwich technique [Figures and ]. Osseograft and healiguide membrane was placed in the defect and sutured with 5-0 vicryl resorbable suture material [Figures and ]. The patient was reviewed 6 months later when the upper left central incisor was found to be asymptomatic, and radiographs showed no further signs of resorption on the tooth.
