ORAL HYGIENE STATE IN CHILDREN WITH CONGENITAL DEFECTS OF THE ALVEOLAR PROCESS ON THE MAXILLA.

Bone plasty of congenital and residual defects of the alveolar process of the upper jaw is a technically difficult surgical intervention which is necessary for full rehabilitation of a patient with congenital lip and palate clefts. This operation creates conditions for stabilization of maxilla fragments and normalization of the upper jaw development and also for successful teeth eruption. The aim of the study - to assess the state of oral hygiene before surgery in children with congenital residual defect of the alveolar process we used Fedorov-Volodkina Hygiene Index and index of the intensity of gingivitis (РМА) according to Masser-Parma.

[THE STRENGTH OF ADHESION TO HARD TISSUES OF NON-VITAL TEETH OF DENTAL PHOTOCOMPOSITE FILLING (RESTORATIVE) MATERIALS IN COMBINATION WITH VARIOUS ADHESIVE SYSTEMS].

Improvement the mechanisms and levels of adhesion forces of dental photocomposite filling (restorative) materials to hard tissues of teeth, improvement of filling materials and increasing their availability is an urgent problem for theoretical and practical dentistry. Aim of the study - experimental evaluation of the strength of adhesion to the hard tissues of non-vital teeth for adhesive systems in combination with modern dental photocomposite filling (restorative) materials. 80 tests of the adhesion strength of the dental photocomposite filling (restorative) material to the tooth hard tissues (shear strength) were carried out for 8 pairs of "photocomposite-adhesive system" using an automated tensometric system.
