| description | Background/Aim. Acrylic-based resins are intensively used in dentistry
practice as restorative or denture-base materials. The purpose of this study
was to analyze the surface structure of denture base resins and the amount
of released potentially toxic substances (PTS) immediately upon
polymerization and incubation in different types of artificial saliva.
Methods. Storage of acrylic samples in two models of artificial saliva were
performed in a water bath at the temperature of 37 ± 1°C. Analysis of the
surface structure of samples was carried out using scanning electronic
microscopy analysis immediately after polymerization and after the 30-day
incubation. The amounts of PTS per day, week and month extracts were
measured using high-pressure liquid chromatography. Results. Surface design
and amount of PTS in acrylic materials were different and depended on the
types and duration of polymerization. The surfaces of tested acrylates
became flatter after immersing in solutions of artificial saliva. The degree
of acrylic materials release was not dependent on the applied model of
artificial saliva. Conclusion. In order to improve biological features of
acrylic resin materials, it was recommended that dentures lined with soft or
hard coldpolymerized acrylates should be kept at least 1 to 7 days in water
before being given to a patient. So, as to reach high degree of
biocompatibility preparation of prosthetic restorations from
heat-polymerized acrylate was unnecessary. [Projekat Ministarstva nauke
