title: Antibacterial properties of periodontal dressings.
abstract: The relationship between the build-up of bacterial plaque at the dento-gingival junction and the development of gingivitis is well established. The susceptibility of patients requiring periodontal surgery to the pathogenic potential of plaque would seem to necessitate the protection of the surgically treated area by a periodontal dressing until adequate plaque control by the patient is possible. In the light of clinical experience, an investigation was undertaken into the antibacterial properties of certain proprietary periodontal dressings and a zinc oxide/eugenol material. None of these materials showed any marked degree of antibacterial activity. One of these materials, Coe-Pak, had been used alone or combined with Cross Pack for all the patients in the clinical survey with very satisfactory results, and it is concluded that this material is successful because of its physical properties and not its antibacterial ones. Careful attention to asepsis, gentle and controlled tissue handling, correct technique, and thorough removal of plaque and calculus are the prerequisites for successful periodontal surgery. The protection of the surgical wound by a dressing of adequate physical properties aids in ensuring uneventful healing. The use of potent antibacterial agents in the dressing is not necessary; a physical barrier to salivary/bacterial contamination and food impaction may be the most important factor.
