The Use of Ozone for the Intensification and Optimization of Oral Hygiene L. M. Lukinikh, S. Y. Kosjuga, Russia. Oral professional hygiene plays a great role in the prophylaxis of caries and parodontium diseases. There are a lot of data about the dependence of dental and parodontium tissues on one hand and on the quality of oral hygiene care, on the other hand. The clinical observation have proved that the long term rational controlled oral hygiene in the background of professional hygiene gives essential prophylactic results and work out necessity to take care of teeth. The practice proves that apart from theoretical knowledge about the oral hygiene and manual habits of thorough teeth cleaning, it is important that each child and adult should have self-control criterion. The sense of teeth smoothness may be a criterion, it can be achieved only by professional teeth cleaning. Grinding and polishing of dental and filling surfaces are being done by special brushes and abrasives pastes, skelps with fine filling and rubber during 5 minutes by horizontal, vertical and round movements, till the sense of teeth smoothness is achieved, that further determines time, technique and quality of teeth cleaning at home. At present, ozonized distilled water (distilled water is borbotaged by ozone mixture with an ozone concentration of 2000 ug/L during 10 minutes) is widely used, for intensification and optimization of oral hygiene. It is being done by gargling with 100 ml of ozonized water per patient (3-5 passages with 20-30 mL each) during professional teeth cleaning stages. Ozonized water increases and improved the qualitative hygienic indexes, and quantitative soft dental deposit of microbial flore composition vividly testifying to it. This investigation allows us to give recommendation about the combined usage of ozone therapy and professional oral hygiene. They are considered to be the methods of effective influence on microbial oral landscape. They are the successful complement and do not produce negative effects on hard dental tissues and parodontium.
