[Root canal treatment at pulpitis, periodontitis using ultrasound].

The aim of our research was the clinical estimation of ultrasound efficiency during root canal treatment at pulpitis, periodontitis. 446 root canals of 164 single and multi-rooted teeth were used for this study. Teeth were treated and monitored for 3 months, 6 months, 9 months, 1 year, 1,5 year, 2 year. All teeth with periapical destructive changes had periapical destructive lesions in x-ray imaging. Patients were divided into two groups. Endodontic treatment of first group combined mechanical and chemical processing with ultrasound divise Pieson Master-400, Endosonore profiles, sodium hypochlorite (NAOCI) +canal lubricant (EDTA). In a second group we used the traditional layout of treatment pulpitis end periodontitis. According to our results, in a first group the X-ray improvement was - after 3 months in I group in 53 (64,6+/-0,7%) patients, in the II group - 44 (53,65+/-2,3%); after 6 months in the I group - 59 (71,9+/-2,2%), in the II group - 56 (68,29+/-0,54%); after 9 months in the I group - 62 (75,6+/-0,56%), in the II group - 56 (68,29+/-0,54%); after 1 year in the I group - 70 (85,36+/-0,18%), in the II group - 63 (76,83+/-0,53%); after 1,5 year in the I group - 76 (92,68+/-2,8%), in the II group - 65 (79,26+/-0,5%); after 2 years in the I group - 77 (93,9+/-2,7%), in the II group - 65 (79,27+/-2,11%). We can conclude, that the ultrasound preparation of the root canal leads us to the considerable lowering of complication of endodontic treatment, though doesn't guarantee their complete absence. In the end we can resume that the usage of ultrasound preparation during endodontic treatment considerably exceed the effectiveness of chemical irrigation of root canal. That is because of its bactericide effect, opening and cleaning root canal system, creation favorable conditions for hermetic filling of root canal after removal of smear line.

[Comparative estimation of laser devices in complex treatment of oral cavity mucous membrane diseases].

The aim of the study was to compare laser devices "Optodan" and portative laser "Baure" in complex treatment of oral cavity mucous membrane diseases. We studied 90 patients: 54 female (60,0+/-0,77%) and 36 (30,0+/-0,7%) men from 18 to 45 years old. All patients had different forms of oral mucosal diseases: Stomatitis aphtosa chronica recidiva had 36 patients (28,9+/-0,9%); Erythema exudativum multiforme - 10 patients (6,7+/-1,5%), Candidosis angulitis - 26 patients (17,8+/-1,46%), Lichen ruber planus ulceroza - 4 patients (4,44+/-1,03%), Trauma mechanicum acutium - 12 patients (11,06+/-2,8%), Stomatitis herpetica - 28 patients (31,1+/-1,48%). All the patients were practically healthy and had no contraindications for physiotherapy. Before treatment to all patients had been recommended means of individual hygiene and several recommendations. The patients were divided into two groups. Every group consisted of 45 patients. 13 patients with Stomatitis aphtosa chronica recidiva, 14 - Stomatitis herpetica, 3 - Erythema exudativum multiforme, 8 - Candidosis angulitis, 2 - Lichen ruber planus ulceroza, 5 - Trauma mechanicum acutium. All the patients underwent symptomatic treatment according to the form and gravity of disease. Patients in a first group in addition had laserotherapy with a laser device "Optodan". Patients in a second group underwent laserotherapy with a portative device (Baurer). The positive results were achieved in both groups, though the first group patients mentioned considerable reduce of pain right after procedures. Our research proved the high effectiveness of laserotherapy in complex treatment of oral cavity mucous membrane diseases. Treatment with device "Optodan" is the most preferable.
