[Obligation to document front tooth injuries in adolescents for forensic purposes].

Following trauma to the anterior teeth during adolescence, exact clinical and roentgenologic records of the findings as well as documentation of the direct and indirect consequences of the trauma are required for forensic, evaluatory, and insurance reasons. Regular control examinations over a period of several years are necessary, since secondary damage may only be demonstrable after a periof of one year or even longer. The use of a uniform medical examination form was recommended to improve and compare documentation of the consequences of injuries to the anterior teeth.

[Comparative scanning electron microscopic studies on the width of the marginal cleft of various composites and on the accuracy of reproduction of the clefts with various casting materials].

Poor results concerning the formation of marginal clefts were obtained with Adaptic and Concise; all composites utilizing the etching technique showed a homogeneous transition between enamel and filling. It should be noted that our findings were taken from extracted teeth 24 hours after the filling. No statement therefore can be made about the long-term behavior of these filling materials in the mouth.

[High hemoglobin concentration and high hematocrit values in patients with homologous kidney grafts].

9% of kidney allograft recipients were found to develop high hemoglobin concentrations and high hematocrit levels. This abnormality was found only in patients carrying their own diseased kidneys. The majority of graft recipients exhibit low normal erythrocyte counts, whereas the patient group described shows high normal values for red cells. It is suggested that erythropoietin secreted from ischemic regions of the patients' own kidneys may be responsible for the observed difference in erythrocyte counts. No adverse effects were noted clinically.

[Therapy of chronic apical periodontitis in traumatically injuring front teeth with ongoing root growth].

Because of the patient's age and the width of the apical foramen, conventional or surgical root canal fillings are frequently not indicated for the treatment of chronic apical periodontitis in teeth whose roots have not yet fully grown. Therefore resorbable paste fillings are applied either to induce deposition of apical hard substance or to bridge the time until root canal filling is possible. In a comparative clinical and radiological study in 171 young patients, Walkhoff's iodoform paste and calcium hydroxide were examined with regard to their inductive effect on the formation of an apical hard substance barrier.

[Clinical studies on the reduction of dental calculus formation by the use of a percent HEDP containing toothpaste].

In a clinical, uncontrolled double blind test, the effect of a 1% HEDP containing toothpaste on the formation and degree of mineralization of supragingival calculus was examined in 50 subjects over two periods of three month each. Considering all subjects the HEDP-containing paste reduced the new formation of calculus by 34.1% or 41.1% depending on the method of evaluation (CS or VM index) and the mineral content by 20.3%.
