[Comparative assessment of the effectiveness of toothpastes to reduce hyperesthesia in inflammatory periodontal diseases]. / Sravnitel'naia otsenka éffektivnosti zubnykh past dlia snizheniia giperestezii pri vospalitel'nykh zabolevaniiakh parodonta.

The purpose of the study is a comparative assessment of hygiene products recommended for increased sensitivity of teeth and having an anti-inflammatory effect on periodontal tissue. The study involved 40 people aged 55-65 years with hyperesthesia and chronic mild and moderate periodontitis, which were divided into 2 groups (20 people each) depending on the toothpastes used based on HAP. Over time, indicators of hygiene, sensitivity, bleeding, PMA indices and the periodontal probing depth are evaluated. The study revealed an improvement of the studied indices in both groups after two weeks of using toothpastes. Both of the studied toothpastes lead to a decrease in hyperesthesia and relief of inflammation, which makes it possible to conduct high-quality oral hygiene. However, a more significant improvement in clinical signs was observed when using paste plant components and bifidobacteria extract. Thus, in the complex therapy of inflammatory periodontal diseases accompanied by hyperesthesia, both studied pastes can be recommended for at least 14 days.

[The long-term results of teeth restoration with composite resin materials: a systematic literature review]. / Otdalennye rezul'taty restavratsii zubov kompozitnymi materialami svetovogo otverzhdeniia: obzor literatury.

AIM: To evaluate by means of a systematic review the survival rate of composite resin restorations in the long-term period and the main factors, affecting the quality of restorations. MATERIAL AND METHODS: An electronic search was performed in eLIBRARY.RU, PubMed/MEDLINE and Scopus. Restriction period was 2007-2017 years. The eligibility criteria included randomized controlled trials, controlled clinical trials and prospective and retrospective cohort studies with at least 3 years of follow-up. RESULTS: The initial search resulted in 328 articles after an initial assessment and careful reading, 17 studies were included in this review. The overall survival rate of composite restorations was 90.7% after 3 years, 89.5% after 5 years, 89.3% after 7 years and 75.6% after 10 years. The highest loss rate was for class II restorations at molars. However there was not enough information about class III and IV restorations and direct veneers. According to majority of publications, type of composite resin material and adhesive system do not affect the survival rate of restorations. The main risk factors of failure are smoking, beverages consumption, bruxism, xerostomia and low level of caries resistance. CONCLUSION: The results of this review suggest that composite resin restorations can demonstrate clinically acceptable results in the long-term period. In case of compliance with treatment protocol the longevity of composite resin restoration is more than 15 years.

[Application of oral Foams Splat Oral Care Foam 2 in 1 in patients with false xerostomia]. / Primenenie ochishchaiushchikh polost' rta penok Splat Oral Sare Foam 2 in 1 pri lozhnoi kserostomii.

The purpose of our study was to identify false xerostomies in students of different nationalities studying at the Faculty of Dentistry of the Sechenov University and to assess the effectiveness of Splat Oral Care Foam 2 in 1 against xerostomia stress-induced. Based on the results of Fox test 40 people were selected who used Splat Oral Care Foam 2 in 1 for three weeks. The participants were divided in 4 groups of 10 depending on the nationality. Oral hygiene was assessed by OHI-S and Silness-Loe indices and saliva was collected by the method of M.M. Pozharitskaya to determine salivation rate. It was found that the use of Splat Oral Care Foam 2 in 1 significantly improves the level of oral hygiene and positively affects the rate of salivation, thereby improving the quality of life.

[Comparative effectiveness of therapeutic toothpastes with fluoride and hydroxyapatite]. / Sravnitel'naia otsenka éffektivnosti lechebno-profilakticheskikh zubnykh past, soderzhashchikh ftorid i gidroksiapatit.

The purpose of the study was to assess the impact of toothpastes containing hydroxyapatite and fluoride on enamel caries resistance and remineralization rate. Study groups comprised 160 patients divided in 2 groups of 80 patients: 40 - at the age of 15-17 and 40 at the age of 18-25 who have been using toothpastes with hydroxyapatite and fluoride during 1 year. The plaque determination was carried out with the use of OHI-S and Turesky indexes. Litmus test pieces were used to determine oral fluid pH. The clinical determination of enamel remineralization rate, dynamics of acid resistance of enamel were carried out. Oral hygiene at baseline examination was poor in both groups. After oral hygiene training, there was a tendency towards indexes decrease more pronounced in the 18-25 age group regardless of the composition of the toothpastes used. Mean baseline oral fluid pH in the observation group was 6.5±0.4, in the comparison group - 6.8±0.4. By the end of the trial there was a tendency towards the increase of the oral fluid pH, which were 7.3±0.3 and 7.7±0.3, respectively. The enamel acid resistance of the patients of the observation group was significantly higher (p>0.05) compared with the group of patients using fluoride toothpaste, as well as the proportion of patients in whom the enamel recovery occurred within 24 hours (47.5% vs. 22.5%, respectively).

[Efficiency of paste and suspension with nano-hydroxyapatite on the sensitivity of teeth with gingival recession]. / Éffektivnost' vliianiia pasty i suspenzii s nano-gidroksiapatitom na chuvstvitel'nost' zubov pri retsessii desny.

The purpose of our study was to assess the efficiency of toothpaste 'Intensive strengthening of supersensitive teeth with nano-GAP' INNOVA and the suspension 'Liquid Enamel' INNOVA on the sensitivity of teeth with gingival recession. We examined 40 people aged 20-25 years. Each group consisted of 20 people: 10 women, 10 men. The first group (observations) used the paste and the suspension for 14 days, and the second group (comparisons) cleaned teeth only with a brush without a paste. Schiff aerial test was performed to assess the rate of hypersensitivity. As a result of the study, it was found that the combination of paste and liquid suspension with nano-hydroxyapatite for 14 days effectively reduced the hypersensitivity of the teeth with gingival recession that was shown by a statistically significant decrease in the Schiff index in the observation group. Thus, this combination is the method of choice in the treatment of hyperesthesia and can be used as an alternative substitute therapy.

[Specific age-related and gender related features in oral status]. / Stomatologicheskii status patsientov v zavisimosti ot ikh gendernykh i vozrastnykh kharakteristik.

The aim of the study was to assess age and gender related features of oral status and oral hygiene. The study included 234 patients (76 males and 158 females) aged 25 to 74 years. It is proved that females have more dental appointments than males mostly because of specific oral conditions associated with pregnancy and menopause as well as better compliance with prevention programs. Thus, females require more intense follow-up than males which should be taken into consideration in treatment and follow-up plans.
