SEM images of dentinal tubules before and after treatment with Duraphat varnish. (A) SEM image of demineralized dentin after Stage I, showing exposed dentinal tubules following tremoval of smear layer. (B) Analyzed SEM image of demineralized dentin after Stage I, showing quantified patent dentinal tubule surface area using image analysis software. (C) SEM image of demineralized dentin after Stage II, treated with Duraphat varnish, showing dentinal tubule occlusion. (D) Analyzed SEM image of Duraphat-treated dentin after Stage II, illustrating tubule occlusion quantification. Scale bar = 50 μm
