Changes in Mechanical and Microstructural Characteristics of Demineralized Tooth Enamel after Conventional and Modified Infiltration Techniques

The research carried out a comparative assessment of the physical and mechanical properties tooth enamel: healthy; demineralized; demineralized subsequently infiltrated with flowable composite according to standard or modified technique. An original in vitro model artificial caries human enamel was used for study, clinical-topographic, color-textural physical-mechanical which correspond characteristics vivo. Comparative analysis results kinetic microindentation samples allows characterize biomaterial from standpoint materials science, determine advantages disadvantages different regimens resin infiltration. infiltration technique are illustrated by significantly greater, as compare classic method, increase microhardness elasticity against background decrease creep index itsdeep zones. reflect fact incomplete obturation microporous deep layers after classical treatment.
