From: Effect of Galla chinensis on the remineralization of two bovine root lesions morphous in vitro
The remineralization effect on subsurface lesion observed by PLM. (a) Comparison of the subsurface lesion before and after GCE remineralization. (b) Comparison of the subsurface lesion before and after treatment with the remineralization solution. The arrows indicate the remineralization zones. The other transparent layers are the demineralization zones. PLM, polarized light microscopy; GCE, Galla chinensis extract.
