For a long time hyaluronic acid has been successfully used in many branches of medicine. It occupies a special place in the aesthetic direction. In recent years, increasingly began to apply medications on its basis in dentistry. The purpose of the study was to find out the clinical effectiveness of treatment for gingival recession with the use of the drug Hyadent BG. Material and methods. In our study we examined 128 patients with gingival recession. After our treatment, the clinical condition of the periodontal tissues was assessed based on the analysis of periodontal, hygienic and indexes of hyperesthesia of the teeth. The results were processed statistically. Results and discussion. Analysis of parodontal indexes in the study groups with gingival recession 12 months after treatment showed that in both groups of studies of the PMA index, were less relevant to before treatment data: with the use of Hyadent BG by 3.3 times, in the control group by 1.2 times, p<0.01. The bleeding index, which was applied to Hyadent BG, was less reliable than before treatment, p<0.01. It should be noted that in the treatment of gingival recession, the minimum bleeding index value is noted with the application of Hyadent BG – 1.35±0.04, p1<0.01. In the study groups, after 12 months of observation, with the use of Hyadent BG, epithelial attachment lost was minimal – 1.73±0.13 mm, p<0.01. As a result of the studies we found out that after twelve months of research there was a decrease of hyperesthesia of the teeth and also indexes of the intensity of hyperesthesia of the teeth. In this case, the value of intensity of hyperesthesia of the teeth in the application of Hyadent BG was by 2.3 times, in control group it was by 1.3 times, p <0,01, lower data before treatment. At the same time the indexes of intensity hyperesthesia of the teeth decreased in the treatment of the group of studies by 1.5 times compared with the values before treatment, p<0.01. After 12 months of observation the improvement of the oral hygiene status was determined for the OHI - S indexes, with the use of Hyadent BG by 1.7 times, and in the control group by 1.3 times less than before treatment, p <0.01. The value of the irritation index after 12 months of study was equal to the value before treatment, p>0.05. In the treated control group and was significantly lower with the use of Hyadent BG by 1.5 times in relation to the data before treatment, p <0.05. The effectiveness of oral hygiene improved significantly in the treatment of gum recession with the help of Hyadent BG in relation to the values before treatment, p<0.01, and according to the criteria of the index corresponded to satisfactory oral hygiene. Clinical evaluation of the state of periodontal tissues in patients with gingival recession after 12 months of observations showed that the "normalization" of periodontal tissues was diagnosed in 22.22±8.0% of the control group and 82.14±7.24% treated with Hyadent BG, p <0.01. Improvement of periodontal tissues was determined in 37.04±9.29% of the treated control group and 17.85±7.24% in the application of Hyadent BG, p>0.05. Conclusions. Thus, the results of our proposed treatment in the long term observations showed convincing advantage Hyadent BG which was confirmed by paraclinical indices.
