Abstract

The aim is to assess the intensity of epithelialization processes in the tissues of the vestibule of the mouth after vestibuloplasty based on liquid cytology data. >. The study included 60 patients with insufficient or completely absent area of the attached keratinized gum in the area of the installed dental implants. The patients were divided into 3 equal groups according to the type of material for closing the wound surface: I — free gingival graft, II — collagen matrix Mucosa, III — free skin flap (split dermal autograft from the anterior surface of the thigh). Liquid cytology was used to assess the state of tissue regeneration. The material was collected before the operation and 7, 14 and 30 days after it. >. By the 30th day after surgery, the highest rates of regeneration were observed after transplantation of free skin. The number of cells of multilayer squamous epithelium in smears was 99%, and when used — 91%, and when using Mucoderm — 85%. >. For the first time, the method of liquid cytology used to evaluate reparative processes in transplanted tissues has proven its viability and can be recommended for use in dentistry.

Key words:
