The results of interviews in 530 patients of two dental clinics (Schwerin and Berlin) are demonstrated. The subject was effectiveness of dental health education aids, as there are displays and boxes. Both educational possibilities appeared to be useful and psychological favourable.

The increase of quality and efficiency in orthodontic treatment is characterized by the development of knowledge based consultations systems. These systems support the dentist to optimate treatment planing. Basis configuration and technical background of those systems are presented.

The development of an acute necrotizing ulcerative gingivitis (ANUG) is connected with preexisting gingivitis and factors of disposition which are able to influence the host resistance. Typical clinical signs of ANUG are necrosis of interdental gingiva, bleeding and pain. Concerning to clinical sign there is a differentiation between the acute and the chronic necrotizing gingivitis. The treatment of ANUG follows the general rules of gingivitis-therapy and will be modified concerning to the clinical signs. It will propose a regular follow-up for prevention of recidivation.

In a cell with artificial saliva the electrochemical behaviour of amalgam specimens of Germadent, Duragam and ANA 2000 is analysed in dependence of the surface treatments carving, burnishing and polishing using potentiodynamic polarization with low polarization rate. The less roughness and content of gamma-2-phase the better the amalgam reacts to corrosion evident in a higher potential, a lower corrosion rate and a higher breakdown potential. Foremost the polish supplies the best resistance to corrosion. Duragam-amalgam is more resistant than Germadent-amalgam. Polished specimens of Duragam react likely specimens of ANA 2000.

Medical evidence on the extension and progression tendency of caries and periodontal diseases have been made by OHI/S, DMF/T-index as well as CPITN with the help of 555 apprentices at the beginning of their vocational training. Shortly before finishing their apprenticeship 415 of then had been examined again in the course of which had to be find out how their teeth-formation had worsened according to periodic examination within 18 month. The results show a clear deterioration of the oral state of health, but evidently indicate that corrections can be gained by continuous care, prevention and early diagnosis.

The caries prevalence was examined in children from the first to the tenth grade in Rostock and Krakow between 1974 and 1988. In Krakow, a town with a preventive orientated dental care program, a significance caries reduction was found. Therefore there is an increase of health and an improvement of oral situation for the children on the way to the goals of WHO for oral health by the year 2000.

Among the few German medicohistorians of the 19th and the early 20th century contributing essentially to the formation of history of stomatology and to its methodologic and cognitive progress. Karl Sudhoff was the most eminent one. He was already very early aware of the full responsibility for stomatology--transferred with the stomatologie examination regulations in 1909--as a task relevant also for his special branch. Therefore, he had already announced stomatologicohistoric lectures at the University of Leipzig in 1913. Sudhoff published his "Geschichte der Zahnheilkunde" ("History of Stomatology") in 1921. Of topical interest is Sudhoff's confession that modern history of stomatology can be dealt with in an experienced and scientific manner only by a medico-historically aducated dentist familiar with the necessary methodologic equipment.

A plasticmodell of a skull manufactured by Deutsches Hygienemuseum Dresden, German Democratic Republic, was produced with Ba2SO4, natural teeth and special constructions for the practical training of students in Stomatological Radiology. Examples show the radiographed x-ray-photograms.

First clinical manifestations of HIV-infection may occur in the oral region. The stomatologist plays an important role in early detection and diagnosis. Therefore he should have good knowledge of all possible oral manifestations of this disease.

Six different plastic materials for temporary crowns and bridges were tested comparatively concerning their biological properties. To this the temperature in the pulp cavity was measured in vitro while making temporary crowns. Also the cytotoxicity was determined by the hemolysis-test. The results obtained showed that there is no thermal irritation of the pulp if the temporary plastic material is applied in an alginate impression as usual in practice. Cytotoxicity of the hardened plastics was not provable. Nevertheless tissue irritation can not be justified when using polymethacrylates and epimine-resin.
