A simplified technique of orthograde MTA obturation on the elected canals of posterior teeth: Two case reports
A 40-year-old asthmatic and phobic male was referred from a local clinic to manage the incomplete fracture of tooth no. 19 that runs from the mesiolingual canal (MLC) to the distal canal (DC) in the furcal region []. There was persistent dull pain on biting that reportedly developed after the shaping session and after all the presenting symptoms of acute apical abscess were controlled. As per the previous records, the mesial and distal canals were prepared by protaper files (Dentsply Maillefer) up to F3 and F5, respectively. There was periapical radiolucency in the mesial root and minimally in the furcal region too.\nWith due informed consent, Interlig fiber (Angelus, Brazil) was bonded across the fracture and the rest of the core was built using a para core after blocking all three canal orifices with GP stumps []. This partial core served as an intracoronal splint and bypassed the need of extracoronal splinting during treatment. It also helped in sealing the fracture in its earliest stage, restricting further ingress of microbes. After verifying the WL electronically, the canals were irrigated copiously with 1.5% NaOCL, 15% EDTA and 2% chlorhexidine solution, respectively. Then, each canal was unitarily obturated with pro root MTA as described in the technique above [].\nThe recall visit at 1 year revealed radiographic evidence of osseous healing in relation to the mesial root apex, and there was no evidence of further furcal breakdown [].
