56 FOGORVOSI SZEMLE ■ 97. évf. 1. sz. 2004. el was 5.0 in 1985 and 3.3 in 2001/2002 in the 12-yearolds.-66%of the 18-year-old adolescents had full dentition as opposed to the relevant WHO goal of 85%. - The level of oral diseases was stable in the 35-44-year-olds. - The rate of edentulousness was 26% in the aged 65- 74 years. Furthermore, 53.3% of children knew that the toothpaste they used contained fluoride; 12.7% of the adults were found to use dental floss; 51.0% of those surveyed were unaware that oral tumours are more frequent among smokers, and only 21.2% saw a correlation between smoking and periodontitis. Conclusions: Findings of the study indicate a failure in Hungary of attaining WHO's goals. Promoting the Hungarian population’s oral health, widening their dental knowledge, and improving their attitudes and behaviours are a task requiring much time and staff effort. PREVENTION IN THE NETHERLANDS VAN LOVEREN Cor Academic Centre for Dentistry, Amsterdam, The Netherlands In the sixties and seventies of the last century, the discussion on water fluoridation increased the awareness that dental caries was a preventable disease. Water fluoridation was not implemented, but all kinds of preventive programs by mass communication were initiated to inform the people and to stimulate them for a preventive attitude and behaviour. The importance of dental health was stressed during visits at well-baby clinics. School dental and medical services stimulated dental health education at primary schools. A national fluoride advice was introduced and professional topical fluoride application became available free of chârge. The big improvement of dental health, however, started only when effective fluoride toothpastes became available and were widely used. This improvement, however, has come to a halt. There are indications that the interest of children and young parents in dental health is declining. The administration shows fewer and fewer activities to inform the public on dental health issues. There is only little time for dental health education at the primary schools. A great deal of the dental health education have to be given in the dental office. However, there is little consensus on how this can effectively be done as there is little consensus on the choice of preventive treatments. There is a group of children still at high risk for dental caries. In addition, older people may become at risk when the interest in dental health or their ability for self care declines. New ways are to be sought to motivate these risk groups or volunteer aids for adequate dental care. PERIODONTAL REGENERATION AND ITS HISTOLOGY WINDISCH Péter Semmelweis University, Budapest, Hungary The aim of our lecture is to present an overview of our human histological examinations which were carried out after periodontal regenerative surgeries, using different regenerative materials. Evaluations were made after GTR therapy in 8 patients, Emdogain in 6 cases, Bio- Oss alone in 2 cases, Bio-Oss-GTR in 5 cases, Bio-Oss and collagen membrane in 3 cases, Emdogain-Bio-Oss in 2 cases, and in further two cases we used Emdogain after subgingival scaling and curettage. Concluding our histological results we can consider that the regenerative material itself can not cause a better or a worse regenerative result. The intrabony part of the defect plays the main role in the amount of the regenerated tissues. In the intraalveolar regenerated part we found that a cellular cementum with periodontal fibres and also the alveolar bone was regenerated. Our immunohistochemical studies further presented that the apical migration of the epithelial cells stopped at the level of regenerated connective tissue. No epithelial rest cells could be demonstrated and the newly formed periodontium was completely connected to the healthy periodontium. That could mean that a certain amount of healthy periodontium is necessary for the regeneration. After a 6 month period of healing not the same amount of new cementum and new alveolar bone was regenerated at the Emdogain treated sites, which shows that the regeneration of alveolar bone follows secondarily or later the regeneration of periodontium. When using bone substitutes these xenograft particles were embedded in newly formed bone and this particles were in none of our cases directly connected to the root surface. Without surgical intervention using regenerative materials during subgingival scaling and curettage no real regeneration could be found.
