[Comparative study of different imbedding materials for light histology of decalcified human teeth].
Four embedding media were compared: paraffin, the mixing "paraplast-piccolyte", Technovit 7100, and JB 4. Each material embedding technic is described. Comparison criteria are: easiness in the technic and method, cutting and trimming qualities, staining, anatomy connections conservation. Results are compacted in a diagram and illustrated by microphotographs. Methacrylate resins, and particularly JB 4, gave us best results.
