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.
First indication and contraindication of surgical procedures are discussed. In comparison of two surgical methods for the treatment of gingival recessions the better effect is by the two-phase-surgery. There is a dependence on age- and tooth-groups.
Studies resulted a prevalence of gingiva recessions of 13.7% at the age group of 15-19 years and of 29.9% at the age group 20-25 years. In consideration of investigated clinical attendant symptoms a structure of required parameters for its development is discussed and emphasized the importance of dental care aspects is emphasized.
Preventive measures, continuously realized in children of dentists cause significantly lower values of Plaque index, Sulcus-bleeding-index, CPITN and caries in all groups of age in comparison to other groups.
A clinical x-ray examination of teenagers in the age of 16-18 had been done in this submitted work as well as the clinical process of the complicated eruption of the lower third molars and all the complications connected with it were analysed at the same time. Therapeutic-prophylactical measures were worked out with the help of examinations which were carried out.
It has been experimentally shown that the x-ray picture cannot represent, with sufficient accuracy, the completeness of a root canal filling. The problems concerned are discussed.
The results of a cross-sectional study of caries prevalence in 22,112 children age 6 to 14 years in Rostock Country are classified as moderate to high according to WHO criterions. Territorial differences in the caries prevalence have a strong connection to the degree of realisation of preventive measures. Over a control period of 20 years the average caries experience in children showed only little changes, a general caries decline couldn't be watched.
The removal of the root canal infection was rendered more difficult with initially present communication of the root canal with the oral cavity, the involvement of relatively resistant microorganisms (enterococci, candida spec. and others) in the infection, and the extensive destructions of the periodontium. Some reduction of the chance of success could be established in case of extensive lesions of the marginal, lateral and apical periodontium after a control period of three years. This indicates the role of the relations between periodontium and endodontium for the result of the therapy of periapical inflammations.
The endodontal treatment need has been forming a clinical order of magnitude. Its decline will be realized by a preventive-orientated oral health care strategy.
