Over a period of 14 days we have treated 27 after special criterious selected patients with 250 mg OTC three times/day. We compared these results with those of 25 patients--of a placebo-group. The analysis included clinical and microbiological parameters. It could be pointed out, that the OTC-therapy results in a significant improvement of the examined parameters stile 6 months after starting with the therapy.

I have investigated twice during a span of 2.5 years, the state of periodontium in female students of secondary schools in Szczecin. The second examination has revealed a narrowing of the attached gingiva in 50.5% of the subjects, without change in the state of periodontium, as represented by the Russell's index.

Within an 8-years-longitudinal study 40 patients with 30 tangential and 28 open bridges were examined. The accumulation of plaque as well as the degree of inflammation of the gingiva adjacent to the bridgework binder and the bridgework bodies were determined by means of selected indices, and the data obtained were compared to those evaluated when the bridges were fitted in. The results show that the accumulation of plaque (on) with open bridge was slightly elevated as compared to tangential bridges whereas the inflammation of the gingiva was significantly increased with tangentially shaped bridgework bodies. For this reason open bridges should be used further more in areas, where aesthetics play only a secondary role.

Behavioral modification is understood as a complex basic process of change. At the place of engraved (indifference or faulty) behavior comes conscious health behavior. Healthy way of life is a dynamic characteristic. Protection against diseases implies knowledge and will; self-interest initiative, own participation, discipline. Health consciousness must be linked with directly responsible action. Children nd juveniles acquire the ability for a life-fit independence in thinking and acting above all in the closed social environment of the family as the smallest unit with personality forming group public. This home education process requires harmonization with the everyday school life and the life outside school

320 workers exposed to chemical in a large petrol-company and 100 nonexposed workers under the nearly same conditions of work and life were examined on damages of their dental, oral and jaw areas. As criterias of the examinations were used DMG/T-Index, Oral Hygiene-Index (Quigley/Hein, Greene/Vermillion) and the Parodontopathy-Index according to Kötzschke. The results of the examinations was a higher prevalence of damages of the periodontium among the workers in the chemical company in comparison to the control group. Within the several groups of workers exposed to chemicals were found significantly differences of the damages depending of exposures.

Using special parameters like the percentage of treated children, degree of treatment and the rate of secondary caries, a retrospective estimation of dental care for children in Rostock County was performed. After that the best results in dental care could be recorded in children of towns. The degree of treatment generally was worse in children of a rural population. On the one hand there is demanded an equalizing of the disproportions in the personal situation in dentistry for children, on the other side there is recommended a yearly analysis of the efficiency of treatment and based on this a territorial program for dental care in children.

The etiology and the pathogenesis, the diagnosis and the therapy of adult periodontitis (AP) are reviewed. Data from epidemiologic studies performed in recent years give a better knowledge of AP-progression. Successful long-term maintenance care give the proof that individual tooth preservation is life-long possible.

Comparison of conventional amalgam restorations produced either in dental college by students or in out-patient department showed that the portion of clinical acceptable restorations was higher at the college. The frequency of secondary caries was distinctively higher in the out-patient department (28.2%) than in the college (16.4%). Secondary caries mainly caused unacceptable quality of fillings of both the institutions. Causes brought about by material defect prevailed at the dental school. In the community errors of preparation mainly led to secondary caries.

The maintenance of teeth for a long time is a main goal of dentistry. Hemisections and root amputations are small surgical methods to conserve impaired teeth for periodontic, endodontic and prosthodontic view part. The successful hemisection of a lower jaw molar is demonstrated by a clinical example.

In the framework of a study involving both experimental and clinical tests, two preliminary tests were made to measure and compare the edge lengths of crowns and inlays and the substance losses after tangential and circular stage-type preparations. As revealed by the results, both the three-face and two-face cast fillings in the lateral tooth area have a longer restoration edge than corresponding cast crowns. The weight loss after crown preparations involving a circular stage is greater by one third than after a tangential preparation. In this context, ways of properly using restorative means of therapy in clinical dentistry are discussed.
