[Study on effects of theraupetic and prophilactic toothpaste with NovaMin on oral cavity in young tobacco users]

THE AIM OF THE STUDY

Was to assess the clinical effectiveness of the course use of toothpaste with NovaMin by smoking and nonsmoking patients along with its complex effects on the oral cavity.

MATERIALS AND METHODS

75 young patients (46 males and 29 females, mean age 23.95±2.9 years) were divided into three groups of 25 individuals. The first group was composed of non-smoking patients using toothpaste with NovaMin. The second group (reference group) comprised patients using placebo toothpaste. The third group was composed of smoking patients using toothpaste with NovaMin. The clinical trials of patients included assessment of functional activity of minor salivary glands, the sialometric analysis, the study on microcrystallization of mixed saliva. The non-specific resistance of oral cavity was studied based on the analysis of absorption reaction of microorganisms by epithelial cells. All patients were questioned about the organoleptic characteristics of the toothpaste. The abovementioned features were assessed before the study, after the first use of the toothpaste, after day 7 and day 14.

RESULTS

The course use of toothpaste with NovaMin resulted in the plaque inhibiting effect (p≤0.05), increased functional activity of minor salivary glands (p≤0.05) promoting increased salivation and oral cavity cleansing. The concept of local recovery of the receptor apparatus of epithelial cells is confirmed for the first group of patients; the non-specific resistance in tobacco users is low, prevalence of Type I epithelial cells is defined (p≤0.05).

CONCLUSION

The evaluated toothpaste affects metabolism in the oral cavity because it was diagnosed that the non-specific resistance of the oral cavity and absorption by epithelia improved in all patients after the course use.

Hypersensitivity of teeth after orthodontic treatment in adolescence

Relevance. In adolescence, focal demineralization after orthodontic treatment is highly prevalent. This, in turn, leads to symptomatic hypersensitivity in the absence of other predisposing factors (recessions, exposure of cervical dentin, increased abrasion, etc.). Reviewed the mechanism for reducing hypersensitivity and remineralizing of calcium-sodium phosphosilicate, also the effectiveness of using a prophylactic toothpaste with this component in adolescents.

Materials and methods. A single-center, non-comparative open study was conducted to evaluate the  effectiveness of the Sensodyne Restoration and Protection toothpaste at the Department of Pediatric Dentistry and Orthodontics, USMU for 4 weeks. 22 adolescents aged 14-16 years with focal demineralization of enamel in the stain stage after completion of orthodontic treatment participated in the study.

Results. The use of toothpaste with calcium-sodium phosphosilicate after a month of use leads to a decrease in the hygiene index by 23.38%, a decrease in hypersensitivity according to the results of the Schiff air index by  56.94% (p ≤ 0.05), and a tendency to an increase in the level of mineralization and a decrease in areas of white  spot lesions.

Conclusions. Toothpaste with calcium-sodium phosphosilicate has a cleansing effect and reduces sensitivity and can be recommended for adolescents with focal demineralization against the background of orthodontic  treatment.

THE EXPIRIENS RESULTING FROM THE PERFOMANCE OF PROFESSIONSL ORAL CAVITY HYGIENE IN PATIENT WHITH A CHRONIC PERIODONTITIS IN COMBINATION WHITH A MEDICATION-ASSOCIATED OSTEONECROSIS OF THE JAW

Thing. The experience of conducting professional oral hygiene in patients with chronic periodontitis in combination with drug-associated jaw osteonecrosis is presented. The goal is to identify the features of the oral cavity status of patients with chronic periodontitis and bisphosphonate osteonecrosis of the jaw (BONCH) on the background of postoperative chemotherapy after using two domestic mouthwashes (OML). Methodology. A clinical examination of the oral cavity of 15 patients aged 50 to 66 years was carried out, which were divided into two groups: the main group (after resection of the jaw segments) and the comparison group (5 and 10 people, respectively). Dental examination included examination of the oral cavity: the condition of periodontal tissues and mucous membrane, determination of the intensity of dental caries and hygiene and bleeding indices. Studies of mixed saliva (SS) were carried out before and after a single and daily course use of two domestic rinses based on chlorhexidine bigluconate and benzidamine and extracts of medicinal plants. Results. The pH value after the course application of OMLPR-1 in patients with BONCH has shifted from weakly acid (6.45 ± 0.4 units) to slightly alkaline (7.15 ± 0.15 units) medium. The structure of the SS before the application of OPLPR-1 was represented by small conglomerates of irregular shape and individual tree crystals of small sizes, and after the double use of OPLPR-1, the properties of the SS improved and medium-sized tree crystals appeared. After the course application of OPLR-2 in these patients, crystal-prismatic structures of a tree form were identified, a tendency to restore the structural properties of SS was determined. Findings. After the course application of LPRS, a tendency to restore the structural properties of SS was revealed. The course use of CPLR stimulates the excretion of SS, cleansing and a feeling of freshness in the mouth. The consecutive use of OPLR-1 and OPLR-2 helps to alleviate the condition of patients, especially against the background of BONCH and chemotherapy.

Аnalysis of the exposure of the medical-preventive toothpaste containing bicarbonate and sodium fluoride on the status of oral cavity in inflammatory diseases of fabric of parоdontium in young patients (clinical and laboratory research)

Relevance of the research topic. Evaluation of changes in the index characteristics of oral hygiene, physicochemical parameters of mixed saliva (pH, buffer capacity of saliva, redox potential, osmolality and others) allows to determine the quality of the effect of toothpaste «Рarodontax ultra clean» on the state of the oral cavity. The use of mixed saliva as a biological fluid of the body as an object of study is confrmed by its high information content and availability of diagnostic material. Studies of changes in mixed saliva, whose components affect the composition, accumulation of microbial plaque and the process of its calcifcation are appropriate.

Purpose. То evaluate the clinical effcacy of toothpaste «Рarodontax ultra clean», the complex effect of its components on the tissues of the teeth and of fabric of parоdontium, to determine the possible mechanism of anti-inflammatory action.

Materials and methods. The experiment involved 58 people. The clinical examination included: Green-Vermillion hygiene indices; bleeding, gingivitis, parоdontium indices. Laboratory studies of unstimulated mixed saliva included parameters: qualitative analysis of the secret, a number of physico-chemical parameters; crystallographic characteristics. For an integrated assessment of nonspecific resistance of the oral cavity, the reaction of adsorption of microorganisms by epithelial cells was used.

Results. In the course of use by patients of toothpaste «Рarodontax ultra clean», an improvement in the oral hygiene condition was noted, a decrease in the rate of plaque formation was diagnosed in 100% of cases, which is clinically confrmed by positive dynamics of hygiene indices (p < 0.05). With regular use of toothpaste, the inflammation of the gums decreases: after 7 days the bleeding of the gums decreases twice, after 14 days - 4.5 times. Summary. The use of toothpaste «Рarodontax ultra clean» leads to a qualitative transformation of the structure of mixed saliva in patients: an improvement in microcrystallization, an increase in salivation, an increase in pH values and bringing it into the range of normal values, an increase in buffer capacity and osmolality. Ingredients such as sodium bicarbonate, silicon dioxide and sodium fluoride contribute to the improvement of metabolic processes in the oral cavity and the adsorption properties of the epithelium after exposure to the investigated toothpaste.

[The increased sensitivity of dentin: the mechanisms of remineralization using toothpaste with tin fluoride]

The purpose of the study was clinical and laboratory analysis of the remineralizing properties and clinical efficacy of the course application of the Sensodyne Rapid Relief therapeutic and prophylactic toothpaste for sensitive teeth with tin fluoride. The study involved 50 overwise healthy patients aged from 18 to 25 years diagnosed with a localized form of hyperesthesia of hard dental tissues and no signs of acute inflammation of periodontal tissues. After 7 days of clinical observation and daily use of the toothpaste the hygienic condition of the oral cavity in all patients improved: oral hygiene index was 1.02±0.2 units; gum inflammation index (PMA) - 8.0±1.5%; the absence of hyperesthesia was diagnosed (1 point, p≤0.05). Examination of patients after 14 and 28 days confirmed the absence of pain in 100%, the organoleptic properties of the toothpaste under investigation were also highly appreciated by the participants. A laboratory study showed that patients have an increase in the pH value of mixed saliva and a decrease in its buffer capacity by 13.4±2.25%, which contributes to a more effective remineralizing effect of calcium ions by calcium-binding proteins of mixed saliva. The concentration of fluoride ions in the saliva of patients of both groups increased by average rate of 34±0.5% per week. The combination of tin and fluoride is more effective than fluoride alone. The presence of tin ions causes a higher ability of fluorides to bind with calcium ions on the surface of the dentin and dentinal tubules, inhibits the process of demineralization, enhances the additive interaction of the ions forming the acid-resistant layer on the surface of the dentin and dentinal tubules, leading to a decrease in hyperesthesia of the teeth.
