[Esthetic evaluation of gingival recession plastic surgery in patients using collagen matrices].

Objective: To conduct a comparative analysis of the aesthetic results of treatment of patients with gingival recession of RD class I and II according to Miller using collagen matrices and connective tissue transplant (CTT).

Material And Methods: The study included 25 patients with grade I and II RD in the area of 107 teeth on the upper and lower jaws. The patients were divided into 4 groups: Mucoderm (=28), Fibro-Gide (=22), FibroMATRIX (=23) and CTT as controls (=34).

[Xenogenic collagen matrix for the treatment of multiple gingival recessions].

Aim: To compare the clinical results of treatment of patients with multiple gingival recessions class I and II according to Miller using the modified coronary advanced flap (MCAF) technique in combination with collagen matrix (CMX) and connective tissue graft (CTG).

Material And Methods: The study included 20 patients with Class I and II Miller gum recessions in the area of 136 teeth. Recessions were divided into 2 groups, the first group was operated with a MCAF+CMX combination (test group), and the second one using MCAF+CTG (control group).

Gene Therapeutic Drug pCMV-VEGF165 Plasmid ('Neovasculgen') Promotes Gingiva Soft Tissue Augmentation in Rabbits.

Currently, an increasing number of patients are undergoing extensive surgeries to restore the mucosa of the gums in the area of recessions. The use of a connective tissue graft from the palate is the gold standard of such surgical treatment, but complications, especially in cases of extensive defects, have led to the development of approaches using xenogeneic collagen matrices and methods to stimulate their regenerative and vasculogenic potential. This study investigated the potential of a xenogeneic scaffold derived from porcine skin Mucoderm and injections of the pCMV-VEGF165 plasmid ('Neovasculgen') to enhance soft gingival tissue volume and vascularization in an experimental model in rabbits.

Endocardial fibroelastosis. Clinico-pathological study of 38 cases.

A clinico-pathological study was carried out based on 38 autopsies of patients with endocardial fibroelastosis ( EFE ): 82% of the cases were below the age of one year. The primary EFE was established in 21 (55%) of the cases, and in the last 17 (44%) it was associated with different congenital heart malformations (secondary EFE ). Different pathological conditions during pregnancy were present in 24% of the cases.
