SEM images of dentinal tubules before and after treatment with Embrace varnish. (A) SEM image of demineralized dentin after Stage I, showing exposed dentinal tubules following removal 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 Embrace varnish, showing dentinal tubule occlusion. (D) Analyzed SEM image of Embrace-treated dentin after Stage II, illustrating tubule occlusion quantification. Scale bar = 50 μm
