The pulps of 24 root canals, eight in each of the three monkeys, were mechanically devitalized and exposed to the mouth flora for about 1 week and thereafter sealed. Microbiologic sampling and analysis was performed in 16 teeth (two of the monkeys) after 7 d of closure (initial samples). The teeth of the three monkeys represented observation times of 90,(More)
This study has shown that microorganisms associated with caries (mutans streptococci, lactobacilli) and marginal periodontitis (Porphyromonas gingivalis, Prevotella intermedia and Actinobacillus actinomycetemcomitans) in pure culture can be stored in VMGA or reduced transport fluid and be recovered sufficiently after 24 h. Sufficient recovery after 24 h of(More)
The present study deals with the ability of 11 bacterial strains, in various combinations, to induce periapical reactions. The indigenous oral bacteria were originally isolated from an experimental apical periodontitis in monkey. Eight of the strains were complete collection isolated from one root canal. These strains were inoculated together, in equal(More)
This study investigated how in-service teachers of foreign languages constructed knowledge and how this knowledge transformed their teaching, their beliefs, and their sense of themselves as professionals in an on-line professional development course based on a constructivist approach. This article provides an overview of research on distance education,(More)
In nine monkeys (Macaca fascicularis) the pulps of 78 teeth were aseptically necrotized. Twenty-six of the pulp chambers were kept bacteria-free by sealing, while 52 were infected by the indigenous oral flora. The results were recorded clinically, radiographically and microbiologically at the beginning of the experiment and after 6-7 months. The final(More)
Eight oral bacterial strains, isolated from an infected root canal, have been investigated for their capacity to produce histolytic enzymes. The determination was performed using methods espoused by two different principles. Eleven out of 12 enzymes examined were demonstrated in the "eight-strain collection". In no single bacterial strain were all enzymes(More)

The purpose of this prospective study was to re-examine the relative importance of various factors in the pathogenesis of angular cheilitis. Sixty-four patients with cheilitis were examined clinically and microbiologically. In addition, a subsample of 23 patients was examined for serum iron and transferrin. The clinical appearance of the lip lesions fell(More)
