[Treatment tactics in children with crown-root fractures of permanent teeth].

The main principles of management of children with root fractures of permanent teeth in the coronal third are presented using two clinical cases as an example. In the treatment of root fractures in the coronal third, an important condition for success is timely flexible or semi-flexible splinting of the tooth for a sufficiently long period (up to 4 months). In the absence of splinting or significant mobility of the coronal fragment after removal of the splint the probability of pulp necrosis is very high, and the method of choice is treatment with calcium silicate cements with their introduction by orthograde or surgical access.

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.

Microslips of teeth with roots intact during removal (=96) of the main group and the control group (=52) were prepared with a Micromet Remet manual petrographic machine.

[The value of restoration marginal fit as risk factor for pathological root resorption in primary teeth].

The presented clinical case describes the need for repetitive dental treatment in a child with pathological root resorption in all the primary molars after pulpotomy and composite resin restoration. Pathological resorption is of inflammatory origin in the majority of cases and an important risk factor for it is marginal leakage of the restoration. According to literature, the optimal restorative choice considering marginal fit are stainless steel pediatric crowns.

Application of BMP-2 and its gene delivery vehicles in dentistry.

The restoration of bone defects resulting from tooth loss, periodontal disease, severe trauma, tumour resection and congenital malformations is a crucial task in dentistry and maxillofacial surgery. Growth factor- and gene-activated bone graft substitutes can be used instead of traditional materials to solve these problems. New materials will overcome the low efficacy and difficulties associated with the use of traditional bone substitutes in complex situations.
