Several factors for caries prediction have been proved in a one-year follow-up study on 73 patients. The white-spot lesions have proved to be a good criteria for caries prediction in this population. These lesions could be combined with the microbiological tests Dentocult SM and Oricult N or with the determination of the buffer capacity (Dentobuff), which did not much improve the prediction.
In about 22% of children aged from 7 1/2 to 12 years we established heavy reaction of anxiety. To proof the influence of Diazepam to dental treatment we carried out clinical investigations in 40 patients. By means of premedication with Diazepam we got a positive effect for readiness of treatment.
Determinations of the wet weight of 48 h human dental plaque have proved that there is a significantly higher plaque wet weight among patients characterized by a low caries experience compared to patients with a high caries experience. The plaque-forming rate of patients with a low caries experience rises with advancing years.
This article presents a animal study on 36 teeth by dogs without definite race. By the histological observation we cannot assess a damage of the pulp by application of CuRAY-FIL with a basic material. The clinical and REM observations after 11 and 24 months by 76 patients pointed out: CuRAY-FIL has a good colour stability and adhesion, however the claims on a optimal filling material for the restoration in the visible area are not accomplished in all points.
The unstimulated and stimulated whole saliva of patients with a very high caries experience were used for the determination of the flow rate, total protein, and the antibacterial proteins lysozyme, S-IgA and lactoferrin as well as the peroxidase and thiocyanate being components of the salivary peroxidase system. The concentration, the specific concentration and the secretion rate were calculated.
The importance of the therapy of premolars and molars with amalgam fillings and inlays in combination with preventive measures is described. By means of own results and the literature an estimation is given.

In a cross-sectional study the contents of phosphate and calcium in stimulated resting whole saliva of persons with high resp. low caries prevalence were examined. In the saliva of persons with a low cares experience significantly higher phosphate--and calcium--concentrations could be found.
We carried out clinical and histological investigations on teeth with superficial and deep caries in which we made an artificial exposure of the pulp to check the reactivity of the endodont. After one year we observed using clinical and x-ray methods successful treatment in 93.4% of the teeth. Histologically the number of successful treatment was 100.0% in teeth with superficial caries and 80.0% in teeth with deep caries.
Despite of the necessity of an increasing primary prevention the therapy of class V cavities will be of greater importance already in the next future. In this review of the literature the indications, advantages, disadvantages as well as the practical procedure for the therapy of cervical lesions with amalgam, metal inlays, composites, glass ionomer cements, porcelain restorations,a nd composite inlays are discussed.
Differing and contradicting information is given in the literature about the number of accessory canals in the bifurcation and trifurcation of molars. The objective of these investigation was to establish the number of such canals by means of serial sections. In 12.5% of the teeth investigated accessory canals were found.
