[Concept of dental restoration using general anesthesia for uncooperative children].

The indication of treating uncooperative children with the help of general anaesthesia is discussed, the prior conditions and the clinical course are debated. Personal clinical experience in the period from 1981-1988 prove that the above mentioned indication has to be ventilated with greatest reluctance. As there are comparatively high dmf-s values (34.1 in the average) at the early age of 3-4 years, it seems to be most important to stress the value of a balanced lactovegetabile nutrition, a sufficient oral hygiene and the indispensable caries prophylaxis by fluorides. This is the only way to avoid extremely high efforts and the limited possibilities of a dental care with the help of general anaesthesia.

[Experimental caries lesions under composite resins].

42 extracted teeth on two sites received a small (2 mm2) surface restoration with a Bowen composite onto the healthy etched enamel without any cavity preparation; afterwards we tried to induce artificial caries by storing the teeth in lactic acid in hydroxyethyl-cellulose-solution. A certain number of teeth was kept in an alkaline buffer solution once a week. All teeth exhibited demineralisation in dentin, though the resin remained perfect in place-even if great areas of dentin had disappeared. The alkaline buffer-solution did not prevent, but only led to a protracted demineralisation, also in the enamel. There seem to be hazardous regions (e.g. fissures, cervical regions), where caries under Bowen-material fillings easily can arise.

[Epidemiological studies in 14-16-year old pupils from schools in Lippstadt. 1. Caries occurrence and oral hygiene].

In a cross-sectional examination we received a current state of the prevalence of caries of 14-16 year old pupils, who attend different types of schools in Lippstadt, a town with a balanced social structure. An average DMF-S-Index of 14.6 (DMF-T: 7.8) was found. The particular results show a clear influence of age, sex and type of school. Comparing our results with former examinations a tendency of reduced caries-prevalence can be derived from the low annual caries-increment.

[Mercury concentrations in blood and urine before and after placement of non-gamma 2 amalgam fillings].

The object of the study was to determine whether mercury concentrations in blood and urine were increased directly after placement of non-gamma 2-amalgam fillings. Our cohort consisted of 45 subjects, male and female, age between 19 and 45 years, who had amalgam fillings and were not exposed to mercury on their jobs. Thirty subjects received non-gamma 2-amalgam fillings, 15 did get new fillings. Cold, flameless atom absorption spectrometry was used to analyze mercury levels in blood and urine samples before and for 24 hours after placement of the amalgam fillings at one hour intervals. Mercury concentrations in blood (before and after) and - before placement of new non-gamma 2-amalgam fillings - in urin were below the normal upper limit in all 45 subjects. Mercury concentrations in urin after placement of new fillings did not show any increase over 24 hours. Median values varied between 1.0 and 2.1 micrograms Hg/g creatinine and thus were also within the normal range.

[Diagnosis and therapy of masseter hypertrophy].

The history, clinical signs and radiographic features of masseteric muscle hypertrophy are illustrated. Functional treatment is described based on the cause and pathogeny of the gnathic disorder. Malocclusion appears to be the most important aetiological factor.

[The use of audio-visual media in the phantom course of restorative dentistry].

The very high standard and increasing number of students in dental education request audiovisual aids. Within the department of restorative dentistry the phantom-course seems to be especially suited to make use of these didactic means. Since 1975 approved methods in Erlangen were introduced and discussed: Video-films can be appropriate supplements to lecturing, teaching in small groups and individual instructions.
