Epidemiological studies in a group of handicapped subjects from the area of Lower Frankonia revealed a surprisingly good oral health. The WHO objective for caries control (DMF-T in 3 to 12 years olds) for the year 2000 has already been reached. In spite of low average values the individual values demonstrated a marked polarisation (30% of subjects of one(More)
Inhalation of mercury vapor is a potential hazard when handling dental amalgam. To prove the safety of modern capsule systems, we tested 21 brands of dental amalgam. Mercury vapor emission was measured at different stages during handling: a) immediately after opening of a capsule package, b) cumulative emission over 24 h of storage of an open package, c)(More)
Extracted premolars with an initial approximal caries were subjected to radiographic and histological examination. Radiographs were taken with the rectangular technique as used for bite-wing radiographs. Digital image processing was found to enhance the image information so that the border of caries lesions as well as histological structures, Retzius lines(More)
Two alternative methods of restoring primary teeth that had multisurface lesions were examined in a clinical longitudinal study. In a paired comparison, stainless steel crowns proved far superior to multisurface amalgam restorations with respect to both lifespan and replacement rate. Stainless steel crowns are not only more acceptable to the patient and(More)
A questionnaire was developed including the Dental Anxiety Scale (DAS) and the Dental Beliefs Survey (DBS) as subscales to examine the epidemiology of dental fear and dental beliefs in Germany. The survey was administered before treatment to a sample of 474 dental patients. Of the respondents 56% were female. The mean age was 34.3 yr (SD 12.4 yr). The mean(More)
Dental amalgam has been considered to have adverse side effects on the immune system. Reports have been contradictory, indicating both an increase and a decrease in peripheral blood lymphocyte counts associated with amalgam restorations. We investigated two groups of patients, one of which was treated with amalgam restorations for the first time. In the(More)
Dental amalgam has been considered to have adverse side effects on the immune system. There are controversial reports, which indicate an increase as well as a decrease in peripheral blood lymphocyte counts due to amalgam fillings. We investigated 2 groups of patients: one group was treated with amalgam restorations for the first time. In the other group all(More)
Measurements of oral health (PBI, DMFS), dental treatment anxiety (DAS) and frequency of dental utilization were taken in a sample of 474 dental patients. Regression analysis shows that DAS scores are significantly correlated with DS, but not with MS and FS. Dental anxiety has a negative impact on the frequency of dental utilization, which is a predictor(More)
