[Oral hygiene and microcirculation of the mucous membrane of the tongue and gums dynamics in patients with burning mouth syndrome as a result of the use of a toothbrush with a gold-zinc electroplating]. / Dinamika gigieny rta i mikrotsirkulyatsii slizistoi obolochki yazyka i desny u bol'nykh s sindromom «pylayushchego rta¼ v rezul'tate primeneniya zubnoi shchetki s gal'vanoparoi zoloto-tsink.

THE AIM OF THE STUDY: Was to assess the level of oral hygiene and microcirculation of the mucous membrane of the tongue and gums in patients with burning mouth syndrome (BMS) as a result of using a toothbrush with a gold-zinc electroplating. MATERIALS AND METHOS: The study included 50 patients of both sexes aged 45-64 years with the diagnosis of BMS divided into two groups. In the main group, the complex of hygienic measures included the use of a toothbrush with a gold-zinc electroplating and a paste with the fluorine content of 1350 ppm. In the comparison group, a regular manual toothbrush and a paste with a fluoride content of 1350 ppm were used for oral hygiene. A control group consisted of 25 healthy people with the mean age of 44±4.5 years without clinical signs of BMS in the oral cavity and concomitant acute somatic pathologies. RESULTS: Tongue mucosa microcirculation level in patients using the toothbrush with a gold-zinc electroplating was significantly higher than in the comparison group using conventional manual toothbrush. Oral hygiene level assessment showed statistically significant better brushing efficacy in patients using the toothbrush with a gold-zinc electroplating. CONCLUSION: The use of a toothbrush with a gold-zinc electroplating contributes to the normalization of microcirculation in the mucous membrane of the tongue and gums and is recommended for inclusion in the complex of therapeutic measures in patients with BMS.

[Optimal operation modes of high frequency monopolar diathermocoagulation in endodontic treatment]. / Opredelenie optimal'nykh parametrov monopoliarnoi vysokochastotnoi diatermokoaguliatsii pri éndodonticheskom lechenii.

AIM: To determine high frequency diathermocoagulation operation modes safe for periodontal tissues and providing the best antimicrobial effect in the root canal system. In vitro study was conducted on 12 extracted upper and lower incisors. High frequency monopolar diathermocoagulation device DK-35MS (2640 kHz; 1.5 kΩ) in six operation modes was used. Root surface heating degree was measured with compact infrared radiation converter (thermal imager Seek Thermal) and distance infrared thermometer Testo 830-T1. After determination of safe operation modes antibacterial effect was assessed. The strains of Streptococcus sanguis, Streptococcus mutans, Enterococcus faecalis, Escherichia coli and Candida albicans were obtained from root canals with inflamed pulp. RESULTS: for endodontic diathermocoagulation procedure the safe operation modes (for the tissues surrounding the tooth) were #3, #4 and #6 with the capacity 3.06-5.4 W for 3 seconds. In operation modes #3 and #6 with the power 5.4 W and 4.1 W, respectively, the best antimicrobial effect was achieved against the studied microorganisms. CONCLUSION: High frequency monopolar diathermocoagulation can be used in endodontic treatment. The recommended power modes of diathermocoagulation in root canals are 4.1 W and 5.4 W, the recommended time is 3 seconds. These operation modes do not cause root surface heating and provide antimicrobial effect against endodontic pathogens.
