Summary:  

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

Materials/Methods: 

•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.
