| case report use of the new MTA 32 roots 4 2016 Root canal treatment with the new MTA Repair HP Author: Dr Fábio Duarte da Costa Aznar, Brazil A 47-year-old female patient presented to our clinic with a radiograph that showed an extensive iatro- genic perforation of the furcation area at tooth #36 (Figs. 1 & 2) that was associated with radiographic bone loss, a vestibular fistula and pain on palpation. The patient had previously received urgent interven- tionconcerningthistoothbyanotherclinicianowing to acute pain from pulpitis. The case was subse- quently recommended for endodontic therapy. After an initial discussion with the patient, anaes- thetic was administered and the tooth was isolated. Aftercreatingacoronaryaccess,weclinicallyverified thepresenceofpulpnecrosisandperforation.Theroot canal was disinfected (crown-down) with an irriga- tionagent(5 %NaOCl)andultrasonicactivationusing straighttips(Irrisonic,Helse).Theworkinglengthwas then determined with the help of a foramen locator. Thefinalpreparationofthecanalwasperformedwith theRECIPROCsystem(VDW). The prepared area was cleaned and refined with an ultrasonic diamond tip (E7D, Helse). In ad dition to the intra-canal disinfection process, calcium hy- droxide(Ultradent)placedinthefurcationareawas exchanged every two weeks, during which time the symptoms were alleviated. The obturation was performed according to the thermomechanical Tagger hybrid technique (Fig. 3) using the GutaCondensor (Maillefer), TP gutta-percha cones(DENTSPLY)andtheMTA-basedsealerMTA-Fill Figs.1 & 2: Initial clinical and radiographic appearance of tooth #36.
