Purpose: to present the 5-year follow-up results of 10 cases treated for furcal perforation repaired with MTA without internal biocompatible matrices. 



•Diagnosis of perforation was confirmed by clinical (presence of pain, episodes of swelling, or abscess), and radiographic examinations. •Procedure: RD isolation – access adjustment – cleaning & irrigating the site. -applied a thermo-plasticized GP plug into the orifice -sealing the perforation with MTA -placing a moist sterile cotton pellet into the pulp chamber and temporarily sealed the access cavity with GIC -After 72 hours, reassessing the root canal system and checked the hardening of the MTA before proceeding with RCT.

Criteria of healing :

1.Clinically – at 6 months, 1 year, 2 years, and 5 years after treatment  there was absence of a (periodontal defect, pain, swelling and fistula) in the area of perforation.

2.Radiographically – absence of radiolucency adjacent to the repair site and absence of periradicular lesions. 

Most highlighted Results: 

  •Starting from the follow-up at 6 months to the end of the 5-year period, 9 of 10 cases were clinically healed.

•There were no episodes of swelling or pain, and the periodontal probing depths were less than 4 mm in all teeth. 

Clinical significance:.

•MTA  provides an effective seal of furcal perforations and clinical healing of the surrounding periodontal tissue.
