Abstract:

BACKGROUND: Resin infiltration is a novel approach in treating non-cavitated caries lesions on smooth surfaces, and the effectiveness comparison between resin infiltration and remineralizing therapy is required.
OBJECTIVE: To compare the effects of resin infiltration and remineralizing therapy on inhibition of non-cavitated lesions in vitro.
METHODS: Three subsurface lesions were created on 35 bovine labial specimens. One of the lesions was permeated with Icon® infiltrant, one was applied by 0.1% NaF solution daily for 7 consecutive days, whereas one lesion remained as the untreated control. Subsequently, half of each specimen was covered with nail varnish (baseline) and the other half was re-exposed to a demineralizing solution for 5 days (experimental). The specimens were cut perpendicularly to the surface, stained with Rhodamine B and observed with fluorescence microscope.
RESULTS AND CONCLUSION: For lesions permeated with Icon® infiltrant and applied by 0.1% NaF solution, the progression of lesion depth was significantly decreased (P < 0.05) compared with the untreated control. Lesions permeated with Icon® infiltrant got more significantly reduced lesion progression (P < 0.05) compared with the ones applied by 0.1% NaF solution. It can be concluded that both resin infiltration and remineralizing therapy have active effects on inhibition of non-cavitated lesions, and filling the pores with Icon® infiltrant can inhibit further demineralization even better.
