    Notes: Abstract The literature is reviewed with respect to several thermal loading situations and their influence on the temperature field in teeth. Breathing, food consumption, and dental treatment are processes disturbing the thermal balance in the oral cavity. The tooth temperature will be affected. These thermal changes result in a physical after-effect on enamel, dentin, and restorative materials, as well as in a histological change of the pulp tissue. Postoperative discomfort is another after-effect reported as a result of dental treatment. Recommendations concerning cooling technique and the use of a cement base are given to avoid this discomfort.In the literature reviewed, attention is mainly focused on temperature within teeth. However, the underlying thermal processes are important in the reported after-effects. It is concluded that more attention should be paid to this phenomenon in future research.

    Notes: Two methods for determining internal stresses in tooth structures were compared under a specific load condition. The numerical method of the finite element method has a definite number of advantages over the experimental photoelastic method. The numerical results obtained by the first method are in reasonable conformity with those obtained by the latter. In addition the sensitivity of the finite element method towards variation of a number of relevant parameters has been studied.

    Notes: Abstract In the autumn of 1969, 1972, 1975 and 1978 clinical and radiographic dental examinations were carried out on about 800 children in The Hague of kindergartens, and 2nd, 4th and 6th grades of elementary schools. The aim of this investigation was to assess what changes, if any, in dental health may have taken place as a result of the campaign ‘Haagse Aktie’, based on dietary and dental health education. In the 5-, 7- and 9-year-old children no differences in dental health were found between 1969 and 1972. The first considerable improvement was found in 1975, especially in children from high social levels. In 1978 the children showed an even better dental health, compared with 1975. In the 5-year-old children the average dsmfs was 6.8. The average D3MFS in children of 7, 9 and 11 years of age in 1978 was 1.8, 3.9 and 8.2. At all socioeconomic levels the improvement of dental health was due to a considerable increase in the percentage of caries free children between 1975 and 1978; 27.6%, 51.8%, 21.2% and 7.4%, respectively, of the 5-, 7-, 9- and 11-year-old children were caries free in 1978, compared with 10.0%, 14.2%, 3.1 % and 0.9% in 1975. However, the reason for the reduction in caries is not known: it can only be the subject of speculation.

    Notes: abstract An epidemiologic survey was carried out to assess the prevalence and severity of periodontal disease in randomly selected samples of employed populations in the Netherlands. Of the 1,337 persons examined by five examiners, 19.8 % were edentulous; 61 % of dentate persons had intense gingivitis in an average of 2.4 segments of their mouths; 53 % had pockets of 3–6 mm and a further 10.1 % had pockets of greater than 6 mm. The prevalence of gingivitis and pocketing increased with increasing age and decreasing levels of education. As no measures of predicting compliance were used and because treatment philosophies differ, no reasonable assessment of treatment needs could be made.

    Notes: Three different capsule or extracellular slime producing microorganisms: Rothia, Neisseria and Bacterionema were tested in SPF Osborne-Mendel rats for their ability to stimulate plaque formation and their effect on the gingiva. Gingival inflammation in the rats was evaluated in histological sections of buccal gingivae.All three the test strains were found to stimulate plaque formation. The high plaque score in the inoculated groups of rats was found to be attended by an increase in the area of infiltrated gingival tissue.
