Measuring functional status in a population survey. The Dartmouth COOP functional health assessment charts/WONCA used in an epidemiological study.
In a population study, a random sample of 398 persons from 20 to 72 years answered the six item version of the Dartmouth COOP functional health assessment charts/WONCA. The results according to age and sex are presented. The charts have been developed primarily for use in clinical settings. In a cross-sectional study in a normal population, the instrument seems feasible in use and it differentiates between the sexes and age groups.

Variation in torus mandibularis prevalence in Norway. A statistical analysis using logistic regression.
The prevalence of torus mandibularis was assessed in two groups of dental patients, altogether 2010 individuals over 10 yr of age: 1181 individuals native to the Lofoten Islands in North Norway, situated at 68 degrees latitude; and 829 patients indigenous to Gudbrandsdal, an inland district in the southeastern part of the country at 61 degrees latitude. Both groups were supposed to be of the same Caucasian stock and, therefore, to have similar genetic predisposition to torus on the average. The following observations were found: 1) the prevalence of torus mandibularis was much greater in Gudbrandsdal than in Lofoten (P much less than 0.001); 2) the prevalence decreased among persons above 50 yr of age as compared with those of the age classes 10-49 yr (P less than 0.01); and 3) it was smaller among women than men (P less than 0.05), mainly due to such a decrease in Lofoten. In a recent investigation of people living in Gudbrandsdal the fraction of the variation of torus that was attributable to genetic differences was estimated as about 30%, whereas approximately 70% of the causes seemed to be ascribable to environmental influences in terms of occlusal stress. It is suggested that dietary habits and number of existing teeth seemed to be environmental variables with an influence on the observed variation of torus prevalence between geographical regions, age classes, and sexes. The question about a possible sexual difference as to the genetic component of liability to torus mandibularis was outside the scope of the present study.

[Uplifting health education].
Health education does not always lead to a change in behavior. This may be because traditional health education often focuses on disease instead of on positive values. Therefore, the new term refreshment is now being used to describe health-promoting activities. Creative medicine refers to all positive renewal which improves people's health.

Relationship between torus mandibularis and number of present teeth.
Comparison of incidence of torus mandibularis and average number of present teeth among 2010 consecutive dental patients over 10 yr of age revealed that these variables seemed to be positively related: patients with torus mandibularis had on the average more teeth present than those without torus (P less than 0.0000001). The difference was statistically significant in all age classes except 50 years and over. In the adolescent age class, 10-19-yr, patients with torus mandibularis had on the average fewer unerupted canines than those without torus indicating that the hyperostosis seemed to be associated with more adequately developed jaws. The decreasing incidence of torus mandibularis with age approximately paralleled the decreasing number of present teeth, indicating that number of functioning teeth seems to be a factor of importance for the maintenance of the trait.

Autologous mixed lymphocyte reactions in rheumatoid arthritis. Characterization of stimulator cells and the recognition unit for autoantigens on the responder cells.
Reduced lymphocyte responses were detected in the peripheral blood (PB) of patients with rheumatoid arthritis (RA) and juvenile rheumatoid arthritis (JRA) in the autologous mixed lymphocyte reaction (AMLR) using irradiated non-T cells as stimulator cells and T cells as responder cells. The AMLR responses of synovial tissue (ST) and of synovial fluid (SF) lymphocytes were normal. Dendritic cells both from the peripheral blood (PB), ST and SF were very potent stimulators in the AMLR and in vivo activated, HLA-DR positive T cells both from ST and SF were able to stimulate autologous PB T-cells in both RA and JRA patients. A rabbit antiserum produced against a fragment comprising the variable heavy (VH) chain region of an IgG3 human myeloma protein (Kup) reacted with peripheral blood T cells and inhibited the AMLR responses. Thus, VH antigens are integral parts of the T cell receptor for autologous HLA-DR (Ia) antigens.

Comparative study of two evaluation methods on radiographic bone loss at the mandibular canines and incisors.
The approximal bone loss of the mandibular canines and incisors was scored with two different units of measurement on 30 sets of standardized paralleling radiographs: 1) with absolute values ("true" millimeter) unrelated to casual variables and 2) with relative values (i.e. percentage of the root length). Absolute bone loss scores revealed that the space between the canines and the lateral incisors of the present material seemed to be more susceptible to bone loss than the spaces between the incisors, with a tendency towards the mesial bone loss of the canines being still greater than the distal bone loss of the laterals. There was a high degree of correspondence between absolute bone loss scores at different teeth and corresponding gingival pocket depths of a previous analysis by the present authors. Relative bone loss scores led to divergent and partly direct-opposite results compared with the absolute scores. The correspondence between percentage bone loss scores and gingival pocket depths at corresponding tooth surfaces was poor. When investigating the susceptibility of different teeth to periodontal breakdown it seems as if bone loss should be expressed in absolute values in the same way as are gingival pocket depths and loss of attachment. If a common standard is being used the results of different investigations may be compared. However, when studying the inception and advancement of the disease at the same tooth over a period of time, or when evaluating the remaining bone support the percentage bone loss method may be of clinical importance.
