Immunohistochemical evaluation of matrix molecules associated with wound healing following regenerative periodontal treatment in monkeys.
Clin Oral Investig 2002; 6(3):175-82CO

Abstract

The aim of the study was to investigate immunohistochemically the expression of matrix molecules associated with periodontal tissues reformed after regenerative periodontal treatment. Chronic intrabony defects were treated with guided tissue regeneration, enamel matrix proteins, the combination of both, or access flap surgery. Five months after healing, the animals were killed, and the healed periodontal tissues were evaluated immunohistochemically by means of polyclonal antibodies against osteopontin, collagen I, and collagen III. The intact (nontreated) parts of the periodontium served as controls. As a general observation, the staining for all investigated matrix molecules appeared to be stronger within the regenerated tissues than in the intact ones. The results failed to reveal any differences in terms of staining intensity or distribution pattern of investigated matrix molecules between the four different treatments. Osteopontin expression was most intense at the border near the newly formed cementum and bone. In the regenerated periodontium, collagens I and III were localized throughout the entire periodontal ligament connective tissue. In the regenerated periodontal ligament, collagen III displayed more intense staining than collagen I. The present results suggest that: (1) even after a 5-month period following surgical periodontal therapy, extracellular matrix molecules associated with wound healing and/or remodelling are more strongly expressed in regenerated than in intact tissues and (2) once an environment for periodontal regeneration has been created, the expression of extracellular matrix molecules associated with the healing process seems to display the same pattern, irrespective of treatment modality.
