[Treatment of halitosis with mouth rinsing agents containing essential oils].

The main reason for halitosis is the enhanced evaporable amount of sulphur compounds in the exhalation, which originates in the oral cavity due to local protein fission. Oral bacteria hydrolyze proteins and further degrade amino acids, which leads to halitosis. In an alkaline environment, many bacterial species found in the oral cavity with their enzymes participate in the degradation of proteins and formation of evaporable sulphur compounds. The presence of bacteria in the oral cavity is associated with different chronic inflammations in the soft tissues of the oral cavity. Mouth rinsing agents, which contain essential oils, ensure the renewal of a normal microbiota in the oral cavity, decreases the quantitative amount of bacteria and products released by proteolytic bacteria. Bad breath was confirmed by measurements made by a portable sulphide monitor or halimeter (Interscan Corporation, Model RH-17E USA). The halimeter quantifies breath measurements in parts-per-billion (ppb) of sulphur compounds. Halimeter measurements of patients showed increased levels of sulphur compounds. Oral mouthwashes containing essential oils possess a typical antimicrobial activity, apparently, they do not form resistant microorganism strains, and they do not cause allergic reactions.

[Saliva and dental caries: diagnostic tests in practical dentistry]. / Sliuna i karies zubov: diagnosticheskie testy v zubovrachebnoi praktike.

New qualitative methods of diagnosis are used now in dental practice. Very popular are saliva diagnostic tests. They are fast and convenient for use. By the saliva one can make diagnosis on the caries activity because of wrong diet (Lactobacillus bacteria in saliva), elevated level of cariogenic microorganisms in saliva (Streptococcus mutans level in saliva) and saliva pH. It is possible to detect the level of Streptococcus mutans and Lactobacillus in saliva using selective diagnostic medium for the bacterial culture.

[Candida albicans adhesion to plastics during correction of removable dentures]. / Adgeziia Candida albicans k korrigiruiushchim plastmassam, ispol'zuemym pri ortopedicheskom lechenii s"emnymi protezami.

Colonisation of denture soft lining materials by Candida albicans can result in clinical problems. The presence of Candida albicans on the upper fitting surface of the denture is a major causative factor in denture-associated chronic atrophic candidosis (denture stomatitis). The fitting surface of denture can act as a reservoir of Candida albicans. The goal of our experiment was to determine of candidal adherence to two soft lining materials -- Ufi gel C temporary and Ufi gel P permanent. Results of experiment show that adherence of Candida albicans to the Ufi gel C temporary was significantly move than for Ufi gel P permanent.
