Introduction: Soft acrylic resins
belong to a group of cold curing materials that are applied to the basal
surface of the dental prosthesis in order to eliminate mechanical
irritation, and to allow for the recovery of damaged or inflamed mucous
membranes, and prepare the oral tissue to accept a new compensation.
The aim of the study was to examine the rhythm of the release of
soft acrylic resin components in three different models of artificial
saliva, during a thirty-day observation period.
Material and Methods: Two soft acrylic resins were used in the
study: poly (ethyl methacrylate)/n-butyl methacrylate and poly (ethyl
methacrylate)/methyl methacrylate, which were deposited in three
different models of artificial saliva within the three observation
periods: one, seven and thirty days. The test involved the detection of
methyl methacrylate, ethyl methacrylate, butyl methacrylate, dibutyl
phthalate and benzoyl peroxide under high-pressure liquid
chromatography.
Results: The amount of released components increased proportionately
with the increase in the duration of the observation period, regardless
of the artificial saliva model. The highest values of all tested
parameters were detected after a thirty-day observation period. The
artificial saliva model did not affect the release of the components,
which means they are freely released into the oral cavity regardless of
the saliva composition of the patient.
Conclusion: As the length of the observation period increased, the
material was solidified, thus ending their use value.
