Abstract
The purpose of the present study was to determine whether granules of Ricinus communis polyurethane resin implanted immediately after tooth extraction interfere with the time course of alveolar wound healing in rats. Progressive bone neoformation in parallel to a decrease in the volume fraction of connective tissue was quantified by a histometric m ethod 1, 2, 3, and 6 weeks after tooth extraction. In spite of the bio compatible nature, the presence of polyurethane resin granules in the cervical third led to a small (9-22%) but significant delay in bone fo rmation in the middle and apical alveolar thirds from the second week on, as compared to controls.
