Abstract
A number of studies have assessed the effect of chlorhexidine on the postoperative healing of periodontal wounds. Available data suggest that rinsing with a 0.2% chlorhexidine gluconate solution does not influence healing while a conventional dressing is in place, but once this is removed healing is enhanced by either a chlorhexidine rinse or gel. Dressings incorporating chlorhexidine also hasten wound healing. Studies undertaken in dogs clearly demonstrate that the beneficial effect of this agent is due to its ability to remove existing plaque deposits and prevent new plaque formation.
