To determine the effectiveness of a simulation method of teaching manual skills modulo 'removable dentures' in a clinical setting. MATERIAL AND METHODS: The material 1 phase of the study were 82 people, students of 3 courses, divided into a control group where the training was conducted with the use of standard phantoms and group study which used a dental simulator CDS 100 of V generation. Material 2 stages presented 48 people who participated in phase 1 and divided into groups similar to the 1 stage, young professionals in 2016. An objective assessment of the quality of preparation for 2 stages made with a scanner Zirkozahn arti s600. RESULTS: In the control group, the main reason for the need for additional correction of the abutment teeth as 1 and 2 is the inadequacy of stage periodontal ledge factor ANOVA with the indicator 1.1 for one phase of the study and 1.15 for 2 stages, indicating that the statistical predictors in this group identity. The group studies found no statistically significant difference in the quality of the executed periodontal ledges 1 and 2 stages of the study, 0.9-way ANOVA factor, which indicates the statistical significance of the predictor as pre-acquisition movements automatism acquired while working with the simulator. CONCLUSION: The use of an interactive computer simulation CDS 100 provides a higher level of acquisition, and the main 'survival' of practical skills, confirmed by subsequent clinical practice, compared with the classical form of education.

[Physiological changes in the morphology of the main structural enamel unit - hydroxyapatite crystal - during its life span (in vitro study)].

The in vitro study by means of complex laboratory techniques including X-ray faze analysis, infrared spectroscopy, scanning electron and atomic force microscopy defined age-related physiological mineralization process as a shift of the structural enamel unit - nanocrystalline hydroxyapatite crystals - TO microcrystal phase. Relevant anatomical sites with age-dependent enamel optical characteristics corresponding to certain ratio of hydroxyapatite phases and the compliance of their color characteristics to composites enamel layers were revealed.
