ABSTRACT

Objective To study the effect of fluoride varnish on microconsistency of enamel after under irradiation in vitro. Methods Normal enamel samples were randomly divided into four groups control group,irradiation group,fluoride varnish group and fluoride varnish-irradiation group.The microconsistency of enamel surface before and after treatment,after anti-caries test was measured by type MH-5 durometer. Results Fluoride varnish had an inhibitory effect on the decrease of enamel microconsistency etched with lactate buffer.The microconsistency in irradiation group was obviously lower than that in control group(P
