‏Perforation repair with collagen barrier and MTA: from destruction to healing

This case demonstrates the successful management of a furcal perforation in a severely compromised mandibular first molar. The tooth presented with extensive structural destruction and a challenging perforation site. badly destructed lower 6 with furcal perforation repaired with MTA Initial management included deep margin build-up and placement of a calcium hydroxide dressing for one week to promote disinfection and tissue recovery. very deep margin build up and (Caoh) dressing for one week During the definitive treatment, a resorbable collagen barrier membrane was carefully applied at the perforation site to serve as an external matrix, allowing for proper confinement of the Mineral Trioxide Aggregate (MTA) repair material and preventing its over-extrusion into the periodontal tissues. The perforation was then sealed with…
