title: Quality of periodontal healing. III: Periodontal width following long epithelial junction or reparative cementum formation.
abstract: The purpose of the present study was to compare the width of the periodontal space following two different marginal periodontal healing reactions (long epithelial junction and connective tissue healing involving formation of reparative cementum) with the width of normal periodontium, either intact or following reattachment. Twelve permanent lateral incisors in monkeys from a previous experimental study on periodontal wound healing on denuded surfaces were selected based on strict healing criteria. The periodontal width was measured histomorphometrically and compared to the periodontal width on the contra lateral side of the same root where reattachment had taken place and with the width of normal periodontal space of neighbouring untreated teeth. The mean periodontal width for both after formation of a long junctional epithelium and reparative cementum were significantly larger than the control width, approximately 290%. This may be taken as evidence of an impaired functional adaptation of the reparative tissue compared to a reestablished or normal periodontal membrane.
