[Hardening and polishing of polymeric articles for medical purposes].

Physico-mechanical and performance characteristics of manufactured articles made of polymers can be improved by treating their surfaces with active solvents during a certain period of time and at a fixed temperature. In such cases the solvent acts upon the molecular structure of the surfacial layer in the polymer, fills and cements its defects. Investigations carried out demonstrated that a short-term action of the solvent improves the durability and toughness of the articles, tends to raise their biological indifference and makes their external appearance look better.

[The sensitivity to antibiotics and disinfecting substances of opportunistic microorganisms isolated from the oral cavity of patients with orthodontic pathology].

Antibiotic and disinfectant sensitivities of opportunistic bacteria, isolated from the oral cavity of normal subjects and orthodontic patients, were under study. The findings evidence that oral microflora of patients with orthodontic conditions is more rich in microorganisms that can induce pyoinflammatory diseases than that in health. Among the isolated opportunistic bacteria strains were found that were resistant to both: antibiotics and disinfectants. Antibiotic sensitivities of the microorganisms isolated from normal subjects and patients were found virtually the same, whereas the strains isolated from the patients have shown a higher sensitivity to disinfectants. The authors emphasize that effective prevention of pyoseptic complications in the maxillofacial area involves not only bacteriologic monitoring and studies of the microorganism sensitivity to antibiotics, but analysis of the bacterial sensitivity to disinfectants as well.
