Microvascular response in the periodontal ligament following mucoperiosteal flap surgery.

Background: When the mucoperiosteal flap is elevated, the gingivo-periosteal vascular plexus and periodontal ligament (PDL) vascular plexus sever their connection with the circulatory tracts that pass through alveolar bone. We studied the effect exerted on the PDL vascular plexus during restoration of the circulatory tract.

Methods: We performed experimental mucoperiosteal flap surgery in adult beagle dogs.
