THE USE OF MEDICAL OZONE FOR PREVENTION
OF POST-OPERATIVE HYPERSENSITIVITY DURING
THE ESTHETIC PROSTHETICS WITH VENEER APPLICATION
Odessa National Medical University, Odessa, Ukraine
The aim of this study was evaluation of the effectiveness of the use of medical ozone for prevention of postoperative tooth sensitivity in aesthetic prosthetics with veneer application. It was stated that the use of medical ozone in the preparation of the surface of the teeth for ceneers leads to the stabilization of the pulp, which is the prevention of endodontiv complications. The proposed method of prevention of endodontic complications with the use of medical ozone gives a high degree of satisfaction of patients with treatment-and good functional and aesthetic results. After the treatment of dental surgery field with ozone the electrical excitability of the pulp does not differ from that of intact teeth.

The study was aimed to evaluation of the effectiveness of the use of medical ozone for prevention of postoperative tooth sensitivity in aesthetic prosthetics with veneer application.
Materials and methods
The study was conducted at the Dental Clinic of Odessa National Medical University in 20112017. The study involved 33 patients who underwent aesthetic prosthetics using veneers. For the prevention of postoperative hypersensitivity in 20 patients tre was used an original method of prevention (I group), and in 13 patients - the traditional means of processing and surface preparation for porcelain veneer (II group).
At the time of the preparation of the tooth beneath the veneer on the treated teeth for 1-2 minutes wore a custom gouttière, which is fed with the ozone-oxygen mixture at a concentration of 15-30% active ozone. For medical ozone generation there was used BOZON-H (NPP "Ekonika", Ukraine). After removing the pattern for the veneer, handling the ozone-oxygen mixture was repeated after 10-15 minutes. Patients in both groups were examined using the apparatus for electroodontometry Digitest (Parkell USA).
Statistical processing was performed using the software Statistica 7.0 (StatSoft Inc., USA).
Results
In assessing the clinical effect of the application of veneers at follow-up visits (in a week, 1, 3, 6, 12 months) their aesthetic parameters (matching the color and surface roughness) were optimal for all veneers. We did not find a hypersensitivity of the teeth after the installation of porcelain veneers

patients of the main group. Dental pulp irritation study occurred in two (6.7%) patients in group comparison. In another case, a 2-year follow-up found a dead tooth pulp, which had a considerable area of composite restorations and secondary caries. In all these cases, the root canal treatment was carried out. Cases of endodontic complications of teeth were absent in the main group.
The electrical excitability of the pulp of the teeth treated with ozone before fixing veneers differed little from those of intact teeth - sensitivity has leveled to 6,7 ± 0,1 mA. At the same time, there was a decrease electroexitability pulp of teeth with veneers set up to 16,5 ± 0,2 mA in the Group II,, which may indicate a disorders of local blood flow and the risk of inflammatory processes in the pulp Indicators of electroodontometry correlated with subjective satisfaction with treatment (r = -0,69 p <0,05).
Conclusion:
1. The use of medical ozone in the preparation of the surface of the teeth for ceneers leads to the stabilization of the pulp, which is the prevention of endodontiv complications.
2. The proposed method of prevention of endodontic complications with the use of medical ozone gives a high degree of satisfaction of patients with treatment-and good functional and aesthetic results.
3. After the treatment of dental surgery field with ozone the electrical excitability of the pulp does not differ from that of intact teeth.
