Elemental analysis of dentinal tubules, based on energy-dispersive X-ray spectrometry. The yellow circles indicate the dentinal tubules, and the orange circles indicate the matrix. The Ca and P levels are higher in the implanted demineralised dentin matrix (DDM) particles than in the non-implanted DDM particles on the polished surface. The Ca and P levels are higher in the dentinal tubules than in the matrix.
