49 FOGORVOSI SZEMLE ■ 97. évf. 1. sz. 2004. THE USE OF EMDOGAIN® IN TREATMENT OF PERIODONTAL INTRABONY DEFECTS DŐRI Ferenc Dept, of Periodontology, Semmelweis University, Budapest, Hungary The therapeutic objective in periodontal treatment is the regeneration of the specific periodontal tissues. The development of enamel matrix proteins for periodontal regeneration begins a new era in periodontal regenerative therapy. Enamel matrix proteins are involved in the formation of cementura and they have the potential to induce regeneration of acellular cementura on root dentin surface. The Emdogain® (BIORA AB, Malmö, Sweden) is an enamel matrix protein used in periodontal regenerative therapy. After the application of Emdogain® during the periodontal regenerative operation, residual adherent and non-dissolvable enamel matrix protein layer remains on the conditioned root surface, which has a barrier-membrane role. This is followed by the appearence of cementoblast. There are different possibilities of use of Emdogain® in periodontal surgical therapy. The regenerating periodontal ligament has a marked osteo-inductive activity, which leads to alveolar bony regeneration. The regeneration of cementura, periodontal ligament and alveolar bone is associated. IMPLANTOLOGY AND PERIODONTAL TREATMENT PLAN: RISK FACTORS FOR EXTRACTIONS ETIENNE Daniel Denis-Diderot University, Paris, France A healthy periodontium is a well known prerequisite for implant placement; however criteria for extractions are not always clear for a clinician in presence of a reduced periodontium. We will evaluate risk factors for extractions and the long term expectations of prosthetic rehabilitation in comparison to a conventional prosthetic treatment. When esthetics is concerned a careful evaluation of bony and soft tissue morphology is mandatory and dental extraction consequences have to be appreciated for the proper timing of implant placement. Periodontal plastic surgical techniques are essential to preserve or restore an adequate soft tissue volume while an optimal prosthetic outcome needs a team approach with a laboratory technician and a prosthodontist. REQUIREMENTS AND PROPERTIES OF AGENTS FOR CHEMICAL PLAQUE CONTROL GANSS Carolina Justus-Liebig University, Giessen, Germany The presentation aims to review the properties of AmF/ SnF2 preparations with respect to basic criteria for chemical plaque control. In this scope, important aspects are efficacy on oral bacteria, on plaque metabolism and accumulation, reduction of clinical signs of gingivitis, possible side effects and stability of the preparation. The antimicrobial properties of AmF/SnF2 are strongly related to the biological activity of the metal ion which inhibits the bacterial metabolism at specific sites. Most studies revealed that AmF/SnF2 is capable of reducing the metabolic activity of dental plaque as well as the vitality of plaque bacteria. Further, a significant reduction of plaque accumulation and a decreased proportion of rods in favor of cocci has been reported. These effects appear to be strong enough to also reduce gingival inflammation. Clinical studies have demonstrated a significant reduction of signs of gingivitis. Only minor side effects like staining of teeth were reported. AmF/SnF2 preparations appear to be not as effective as chlorhexidine (0.2%) but are suitable for long-term use. Even if not capable of replacing mechanical plaque control, the combined use of AmF/ SnF2 preparations appears to be more beneficial for gingival health than mechanical oral hygiene alone. Especially in gingivitis risk patients (i.e. heavy plaque formers), in the elderly or in handicapped people the long-term use of AmF/SnF2 preparations should be recommended. PERIODONTAL MAINTENANCE GERA István Semmelweis University, Budapest, Hungary After the successful completion of comprehensive active periodontal treatment the periodontium is intact and inflammation-free, but functionally disabled. Therefore after the therapeutic phase for maintaining periodontal health, the patients should be regularly checked and a professional maintenance program should be started. This regular recall program is called periodontal maintenance. The periodontal maintenance program covers the following activities: 1. Providing repeated motivation to the patient and instructions for oral hygiene at home. 2. Regular supra and subgingival scaling and root planing. 3. Regular monitoring of the quality of restorations and if necessary correcting. 4. Monitoring the periodontal attachment
