ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effect of chemical compounds extracted from Galla chinensis on enamel surface rehardening in vitro.</p><p><b>METHODS</b>Sixty bovine enamel blocks with early carious lesions were randomly divided into six groups group1 treated NaF (positive control); group2 with GCE; group3 with GCE-B; group4 with GCE-B1; group5 with GCE-B2 and group6 with deionized water (negative control). The lesions were subjected to a pH-cycling regime for 12 days. Surface enamel microhardness was measured on the enamel blocks before and after demineralization. After pH-cycling, and the percentage of surface microhardness recovery (SMHR) was calculated.</p><p><b>RESULTS</b>Obvious increase of the surface hardness of the enamel was observed in all the treatments except GCE-B2 and deionized water (P < 0.05).</p><p><b>CONCLUSIONS</b>The present study demonstrates the potential of the three GCEs (GCE, GCE-B and GCE-B1) to effect net rehardening of artificial carious lesions under dynamic pH-cyclic conditions.</p>
