[Gender-related preferences in the choice of methods for aesthetic and functional rehabilitation in dentistry]. / Predpochteniia muzhchin i zhenshchin pri vybore metodov ésteticheskoi i funktsional'noi reabilitatsii v stomatologii.

The aim of the study was to assess gender-related preferences in the choice of oral rehabilitation methods. The study involved 225 patients aged 16-75. The analysis included patients survey and the assessment of actual procedures received during one year follow-up. The study revealed women to be more attentive to oral health issues resulting in more regular appointments and better compliance. Dental treatment before planned pregnancy was, however, completed in only half of the patients. When choosing materials and constructions for oral rehabilitation the leading criteria for men were 'quality' and 'safety', while women chose 'esthetics' and 'quality'. Both genders would like to have their teeth 'whiter' but women undergo bleaching procedures more often. The dentists need to consider the revealed gender-related features for planning of prevention, treatment and full oral rehabilitation.

[Assessment of antibacterial efficacy of ozone therapy in treatment of caries at the white spot stage]. / Antibakterial'naia éffektivnost' ozonoterapii pri lechenii kariesa v stadii belogo piatna.

Effect on cariogenic flora is the key toremineralizing therapy efficacy in treatment of initial caries (at the white spot stage). Ozone in dentistry is used as a highly effective antibacterial agent. Treatment of white spot lesions with the ozone-air mixture leads to significant increase of efficacy in non-invasive treatment of initial caries. OBJECTIVE: clinical and microbiological assessment of antibacterial efficacy of ozone therapy in treatment of caries at the white spot stage. MATERIAL AND METHODS: The trial recruited 86 patients for non-invasive treatment of caries at the white spot stage which included the complex of professional oral hygiene, medicamental treatment of white spot lesions with hydrogen peroxide 3% and chlorhexidinedigluconate 0,2%, treatment with the ozone-air mixture and application of hydroxyapatite Са2+. Material for microbiological study was received before the treatment, after the complex of professional oral hygiene and medicamental treatment of white spot lesions conducted as well as after the treatment with the ozone-air mixture. RESULTS: Before the treatment up to 16 kinds of microorganisms on the surface of white spot lesion were detected with the following shares: S. mutans (19.9%), S. salivarius (15.1%), S. epidermidis (8.7%), S. mitis (6.5%), Lactobacillus (6.5%) and different kinds of staphylococci (10.8%). After the complex of professional oral hygiene and medicamental treatment conducted decrease in number of cariogenic microorganisms was indicated as follows: S. mutans - from 1·105 to 1·104, S. salivarius - from 1·107 to 1·106, S. epidermidis - from 1·105 to 1·104, S. mitis - from 1·104 to 1·103, Lactobacillus - from 1·104 tо 1·103. After the treatment of tooth enamel with the ozone-air mixture increase in microorganisms was not observed. The efficacy of ozone on cariogenic microorganisms exceeds significantly the efficacy of 3% hydrogen peroxide and 0,2% chlorhexidinedigluconate. CONCLUSION: It is strongly advisable to include ozone in protocol of non-invasive treatment of initial dental caries.

Effect of long term application of toothpaste Apadent Total Care Medical nano-hydroxyapatite. / Otsenka effektivnosti dlitel'nogo primeneniya zubnoi pasty Apadent Total Care, soderzhashchei Meditsinskii nano-gidroksiapatit.

The aim of the study was to evaluate the efficacy of toothpaste «Apadent Total Care¼ containing nanocalciumhydroxyapatite and its influence on caries resistance of tooth enamel and teeth sensitivity. The study involved 30 people: 15 patients aged 17-25 years and 15 aged 35-44 years. Study participants used «Apadent Total Care¼ toothpaste with nanocalciumhydroxyapatite. To evaluate the effectiveness of toothpastes clinical assessment of enamel remineralization rate was carried out, as well as the dynamics of enamel acid resistance and teeth sensitivity (Shiff index). Clinical evaluation of tooth enamel before the procedure and after 3 months of use of toothpaste with nanohydroxyapatite showed the improvement of all indices. Time for complete remineralisation of enamel in both groups did not exceed 3 days. Acid resistance of tooth enamel increased by 1.65 in group I and 1,75 in group II. The Schiff index after 3 months of using «Apadent¼ toothpaste also decreased in both groups.
