Morphometric analysis of cellular and vascular changes in gingival connective tissue in long-term insulin-dependent diabetes.

This study examined cellular and vascular changes in gingival connective tissue samples by stereologic point-counting procedures and interactive digital analyzing systems in long-term insulin-dependent diabetes mellitus patients. Gingival connective tissue capillaries representing a clinically healthy sulcus with no evidence of periodontal disease at the site of biopsy were studied in 29 patients with diabetes. Based upon their long-term medical records, 19 were identified as having poorly controlled (PIDD) and 10 as controlled insulin-dependent diabetes mellitus (CIDD).

Dental health and dental treatment needs among recruits of the Finnish Defence Forces, 1919-91.

The first two surveys of the dental health of young Finnish men were conducted in 1919 and 1965. The objective of four subsequent surveys (1976, 1981, 1986, and 1991) was to collect both interview and clinical examination data for the monitoring of changes in the oral health status of the recruits. A significant reduction in self-reported toothache, gingival bleeding, and number of decayed teeth was observed from 1976 to 1991.

Assessment of the effect of an oscillating/rotating electric toothbrush on oral health. A 12-month longitudinal study.

The aim of this 12-month parallel design controlled clinical trial was to assess the effect of the Braun Oral-B Plak Control electric toothbrush on supragingival plaque and gingival health, and to compare it with a conventional soft manual toothbrush (Jordan). A total of 111 patients aged between 20 and 63 years, from a general population, with bleeding on probing at 30% or more of all sites examined were entered into the study. At baseline, immediately after periodontal examination, all volunteers received a thorough scaling of their teeth.

Risk assessment of recurrence of disease during supportive periodontal care. Epidemiological considerations.

Although it is accepted that the primary cause of periodontitis is bacterial infection of long duration, there are a number of risk factors which may increase the probability of recurrence of periodontal disease during supportive periodontal care. The risk may in such cases be caused by other factors than poor oral hygiene measures per se. Cross-sectional and longitudinal studies show conflicting results concerning age as a risk factor for periodontal disease.

Dark field microscopy of the subgingival microflora in insulin-dependent diabetics.

The subgingival microflora was assessed by means of dark field microscopy in 106 pockets of 47 subjects with long-term insulin-dependent diabetes mellitus (IDD). The microbiota of 55 healthy sulci (probing depth < 4 mm) and 51 periodontally diseased (probing depth > or = 4 and 6 mm) pockets were analyzed. The mean duration of the IDD of the diabetic subjects was 23.
