Abstract:
Background: Dental caries is a widespread, noncommunicable disease affecting half of
world’s population. Thus, prevention rather than mere treatment of dental caries has
become a decisive goal in dentistry. Therefor the adequacy of laser (Erbium,
chromium-doped yttrium, scandium, gallium and garnet) irradiation and
remineralizing agent were tested on artificially demineralized enamel.
Methodology: Twenty human molars were selected, scaled, polished and sectioned
into two equal buccal and lingual sections (n=40). Surfaces were coated with acid
resistance nail varnish except for enamel window of 4x4 mm. The specimens were
embedded in demineralizing solution for 3 days. They were randomly divided into
two groups (n=20) according to type of remineralizing agent, group (MI): MI paste plus
and group (RE): Remin Pro. They were applied according to manufacturer’s
instructions. The groups were then divided into two subgroups (n=10); groups (MIL)
and (REL). In both groups specimens were treated first with Er, Cr: YSGG Laser then
remineralizing agents were applied. The weight % of Calcium and Phosphate were
measured using EDX. The measurements were done before any treatment (control
group), after demineralization and after remineralization. Representative specimens
were selected for scanning.
Results: The results of the study showed that (MI, RE and MIL) weren’t able to restore
the minerals compared to the control group. While REL group was the only group
similar to the control group. In addition, the intergroup comparison showed that REL
had the highest remineralization compared to other groups.
Conclusions: The combined use of laser and remineralizing agents improved enamel
remineralization
