Fig. 1. Analysis of silver diamine fluoride (SDF) application effects using microscopic computed tomography (microCT). (A) Two-dimensional reconstructed coronal and horizontal slice images. A small defect before SDF application (arrows on the left) is remineralized after application (arrows on the right). (B) Three-dimensional reconstructed microCT image showing dental caries and remineralization after SDF application. Scale bar, 2 mm.
