All of the named factors eventually lead to the development of irreversible inflammatory-dystrophic and destructive changes in periodontal tissues. During the recent years the method of guided tissue regeneration that uses membranes is being successfully used for the treatment of periodontal diseases.</p><p>A comparative study on the mandibular alveolar mucosa lesion healing during application of different types of biological matrixes containing decellularized amniotic membrane, decellularized amniotic membrane in combination with platelet-rich plasma (PRP) growth factors, and decellularized amniotic membrane in combination with PRP growth factors and hyaluronic acid was performed. The study proved the acceleration of the processes of wound area reduction. Under experimental conditions, the wound healing lasted from day 3 to day 5 of the study; however, the rate of reduction of the wound area was slower, which indicates an alterative stage of the acute inflammatory process. During days 5 – 7 (stage of regeneration, the 2<sup>nd</sup> phase of wound process) the wound area reduced rapidly and by day14 a complete epithelization of the surgical wound was observed in all groups using decellularized amniotic membrane. In the group using the combination of PRP growth factors and hyaluronic acid the epithelization of wound was already observed on the day5. In the control group healing occurres with scar formation.</p>}, number={6}, journal={Journal of Education, Health and Sport}, author={Vyshnevska, H. O. and Kakabadze, Z. Sh. and Schnayder, S.
