Role of mineral trioxide aggregate in management of external root resorption
A 22-year-old male patient reported to the department of endodontic, with the chief complaint of pain with the lower right back region of tooth. He gave history of discontinued root canal treatment with same tooth []. There was no relevant medical history.\nOn clinical examination of tooth #46, tooth was temporarily restored, tender to vertical percussion and there was no mobility seen. Intraoral periapical radiographic examination of tooth #46 revealed extensive apical root resorption on both the roots, associated with diffused periapical radiolucency some bone loss.\nTaking into consideration the extent and the severity of the resorption, it was planned for orthograde MTA obturation of the canal space to arrest the resorption.\nThe existing access cavity was modified and working length of the tooth was determined with help of apex locator, Propex-II (Dentsply). Canals were cleaned and shaped with the help protaper rotary (Dentsply, Tulsa dental specialities, Ballaigues, Switzerland) up to F2, irrigating with copious amount of 3% of sodium hypochlorite, (Vishal dentocare Pvt. Ltd., Ahmedabad, Gujarat, India). This was followed by irrigation with normal saline to remove any remnants of hypochlorite, latter canals were dried with absorbents points and calcium hydroxide (R C Cal, Prime Dental products, Kalher, Thane) as an intracanal medicament was placed in canals followed by a temporary restorations for 1 week.\nAfter 1 week, temporary restorations were removed, canals were cleaned and dried. MTA, pro-Root MTA (Dentsply, Tulsa Switzerland) was manipulated according to manufacture instructions. Both the distal and mesial canals were obturated with MTA, material was placed in the canals with amalgam carrier and was condensed vertically with hand pluggers. After completion of obturation orifices were sealed, followed by postendodontic restoration [].\nThe patient was recalled after 6 [] and 24 [] months for clinical and radiograph follow up. Clinical examination of tooth #46 was functional without sensitivity to percussion or palpation. Tooth showed normal physiologic mobility and no periodontal pockets on probing. Intraoral periapical radiograph showed regression in the size of periapical radiolucency with sign of osseous repair and no further progression of ERR [].
