Based upon the analysis of 310 dental status assessment forms from 5 regions of Russia there were disclosed data on oral hygiene index, oral hygiene education, controllable cleaning procedure, professional hygiene, recommendations to clean oral cavity, regimen of nutrition and secondary visit terms. It was established that delivered treatment not in the fool corresponded with the protocol of patient treatment "Dental Caries" confirmed by Russian Deputy Minister of Health and Social Care 17 October 2006.

Discussing the problems of caries resistance and caries susceptibility, we should remember that normal status of dental enamel is maintained by the dynamic equilibrium between demineralization and remineralization processes. Some aspects in the structural resistance of the enamel, determined by its maturing, are discussed. Data on the role of oral factors reflecting the status of the organism are presented. The authors do not agree that caries resistance, which is permanent throughout life, is determined by the CDL index. They give their arguments in favor of introducing the notion of "caries risk" and the criteria for evaluating this risk.

The purpose of the study was to develop the optimal variant of using remineralizing solutions to improve dental enamel resistance; for this the efficacies of 10% Ca gluconate solution, 1% Na fluoride solution, and 3% remodent solution were examined. These solutions were found to promote a sooner 'maturation' of the enamel than is natural and to improve caries resistance of the enamel.

The authors analyze the functional value of pulpless teeth. A pulpless tooth retains its structure, shape, and function for a long time and, in authors' opinion, effectively performs.

The status of the oral cavity (dental caries and periodontal diseases detection) was examined in confectioners. Salivary excretion type was found changed, this shift being explained by more intensive caries and periodontitis. Prophylactic measures helped reduce caries morbidity in this population.

Histamine release from basophilic leukocytes under the effect of autoantigens isolated from involved gingival tissue was examined in periodontitis patients and normal subjects. Anaphylactic autosensitivity was found to be increased in this condition. The results evidence the advisability of antianaphylactic agents administration to patients with periodontitis exacerbations.

Water-free cattle parietal peritoneum was used in surgical treatment of 62 patients with severe periodontitis. Use of xenoperitoneum in multiple-modality treatment of periodontitis was conducive to bone tissue regeneration in bone pockets, to a more rapid recovery of gingival temperature round incisors and molars.

The content of lactate in mixed saliva in severe diabetes mellitus associated with multiple caries was 5 times and in diabetes of medium severity 3.5 times greater than in caries-resistant subjects. This increase was largely caused by diabetes proper, since in multiple caries without diabetes, the lactate content was increased only 2-fold. The amount of pyruvate in saliva in multiple caries without diabetes was approximately the same as that in diabetes mellitus coupled with multiple caries. Preliminary administration to the oral cavity of 100 ml of 50% saccharose for 10 minutes (without swallowing) raised the saliva lactate content several times as compared to that in the same subjects before saccharose administration. The lactate content in saliva was particularly high in severe diabetes mellitus. Administration of 50% sorbitol of the oral cavity for 10 minutes did not increase the lactate content in saliva. Upon administration of saccharose lactate dehydrogenase activity in saliva significantly descended while sorbitol dehydrogenase activity significantly increased. Administration of sorbitol solution to the oral cavity did not produce any essential effect on sorbitol dehydrogenase activity in saliva.

X-ray spectral microanalysis was applied to study Ca and P contents in superficial, intermedial and deep enamelum zones in 15 human teeth with different fluorosis manifestations which were extracted for orthodontic purposes. In 3rd grade fluorosis, detected were a statistically reliable decrease in Ca content in enamelum superficial zone and a tendency of its depleting in deep zones. Ca/P ratio was also lowered that indicated mineralization impairment in solid tissues of the teeth. This should affect the choice of the technique of therapy and prevention of different manifestations of teeth fluorosis.

Antibacterial and proteolytic enzyme lysoamidase was used to treat periodontitis and a range of diseases of oral mucosa. The results displayed its major advantages over trypsin and allowed us to recommend it as an effective means of local treatment in the combined therapy of these disorders.
