Характеристики показателей микротвердости светоотверждаемого композита при различных протоколах полимеризации

Abstract

Цель исследования. Сравнительная оценка изменений показателей микротвердости светоотверждаемого композиционного материала различных эмалевых оттенков в зависимости от времени полимеризации при использовании стоматологического фотополимеризационного устройства галогенного типа. Материалы и методы. Исследованы показатели микротвердости по Виккерсу (HV) образцов светоотверждаемого композиционного микрогибридного материала «Charisma Opal» (Германия) эмалевых оттенков: А1, А2, А3. Результаты. Показатели H v лицевой поверхности были более высокими в отличие от тыльной поверхности образцов (р=0,000), за исключением оттенка A 2. Заключение. Установлено, что время фотополимеризации оказывает большое влияние на показатель микротвердости композитов.

The aim of the research. Comparative evaluation of indicators changes in microhardness of the light-curing composite material of different enamel shades depending on the time of polymerization using dental photo-polymerization halogen type device. Materials and methods. Were examined the indicators in microhardness by Vickers Hardness (HV) of samples of the light-curing microhybrid composite material «Charisma Opal» (Germany) enamel shades: A1, A2, A3. Results. Indicators H V in face were higher in contrast to the back surface of the samples (p = 0.000), except shade A 2. Conclusion. It is established that the photopolymerization period has the great influence to the indicator of microhardness composites.
