Summary: | Introduction: Surface integrity of dental elastomeric impression
materials that are subjected to disinfection is of major importance
for the quality of the final prosthetic restorations.
Aim: The aim of this qualitative Scanning Electronic Microscopy
(SEM) study was to reveal the effects of immersion or ozone
disinfection on the surface of four dental elastomeric impression
materials.
Materials and Methods: Four dental elastomeric impression
material brands were used (two vinyl polysiloxane silicones, one
polyether, and one vinyl polyether silicone). Total of 32 specimens
were fabricated, eight from each impression material. Specimens
were immersion (0.525% sodium hypochlorite solution or 0.3%
benzalkonium chloride solution) or ozone disinfected or served
as controls and examined with SEM.
Results: Surface degradation was observed on several specimens disinfected with 0.525% sodium hypochlorite solution.
Similar wavy-wrinkling surface structures were observed in almost
all specimens, when treated either with 0.3% benzalkonium
chloride solution or ozone.
Conclusion: The SEM images obtained from this study revealed
that both immersion disinfectants and ozone show similar
impression material surface alterations. Ozone seems to be noninferior as compared to immersion disinfectants, but superior as
to environmental protection. |
