In the periodontal prophylaxis and therapy the most important steps are the adequate professional and individual oral hygienic interventions. Several factors are interfering with our attempts to maintain good oral hygiene either on the individual or professional basis. Among these many are artificially created during dental treatments. In the first part the clinical and experimental data on the effect of bad restorations on the health of periodontium are overviewed. The literature shows that these factors per se do no cause damage to the periodontium but the altered sub- and supragingival plaque accumulation due to these factors are responsible for the pathological conditions. The author deals with the effects of the placing and quality of crown margins, the smoothness of subgingival restorations, the shape and dimensions of interproximal areas, contact surfaces, the shape of pontics and the occlusal surface on the plaque accumulation and on the practice of professional and individual oral hygiene. The periodontal prophylactic philosophy and the standards of quality dentistry as well as the basic principle of periodontal prosthodontics are also discussed.
