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

N= 10 cases.


•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. à 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 :

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.

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.
