(A) A sketch of a prepared tooth disk partially submerged in the water secured on a support in the sample holder. C1 and C2 are composite filled cavities with different geometries; D is dentin; E is enamel. (B) One slice of μCT scan of a filled tooth. (C) A three-dimensional reconstruction of composite in dentin (area enclosed by the ellipse in (B)). (D), the volume of an object containing dentin, enamel, and composite as a function of threshold value. T* is the optimal threshold. Inset shows ImageJ reconstructions of enamel only and an object containing enamel, dentin, and composite analyzed at increasing thresholds.
