When performing non-surgical furcation perforation repair, use of an internal matrix material will limit repair material extrusion, which reduces long-term inflammation. No difference between HAPSET and HA in terms of duration of inflammation and both promoted bone deposition directly contacting the repair material

Perforations in visible, accessible locations may be repaired with the aid of an internal matrix to increase prognosis by reducing hemorrhage and contamination affecting the repair material and preventing extrusion of the repair material
Amalgam is better than GP WVC (due to extrusion as a cause of failure.) A delay in repair did not affect outcome. Surgical repair appears to be highly successful.
Attempting to repair a perforation better than no repair. The use of CAOH for 1 month or more results in more periodontal destruction. Amalgam better than Cavit for repairs.
2-6 weeks of CAOH prior to obturation resulted in healing of teeth with suppuration and internal resorption.

Immediate root perforation repair had better healing and decreased perio destruction
If managed properly, perforation repairs can result in long-term clinical success.
MTA can provide a biocompatible and long-term effective seal for root perforations in all parts of the root.
Repairing furcal perforations with MTA is associated with a good short-term (5 yr) clinical outcome.
MTA provides an effective seal of root perforations and shows promise in improving the prognosis of perforated teeth that would otherwise be compromised.
