A simplified technique of orthograde MTA obturation on the elected canals of posterior teeth: Two case reports
A 31-year-old male patient visited my office for a persistent symptom associated with tooth no. 2. The medical history was noncontributory but he had a present history of unsatisfied endodontic treatment from his previous dentist with respect to this tooth. No written or radiographic records were available with him. His mouth opening was less than normal. On exploration, the mesiobuccal (MB) and distobuccal (DB) canals were found to be filled and were satisfactory. The unfilled palatal (PC) was well enlarged and prepared, but its apical constriction was grossly violated to such an extent that a 55 no. H file went through it easily []. Apart from apical transportation and zipping, apical vertical root fracture (VRF) was also suspected. Therefore, of the many treatment options proposed, orthograde MTA obturation of the entire PC was elected and informed consent was granted.\nThe working length was determined electronically (Raypex 5, VDW GmbH, Munchen) and the canal was circumferentially filed upward using the H file no. 20 through 40. Further shaping was avoided as it was already shaped. Copious irrigation with 1.5% NaOCL and 15% EDTA was performed using a side-vented 27-gauge irrigation syringe. Then, white ProRoot MTA (Dentsply, Tulsa Dental Specialties, Tulsa, TN, USA) was packed in the PC [] as per the general technique described below []. The postoperative period was uneventful and tenderness to percussion resolved in 2 weeks’ time.
