Dog dental enamel ultramorphology: Analysis by scanning electron microscope
Preliminary report
Keywords:
enamel, ultramorphology, teeth, dog, SEMAbstract
Mammals´ enamel is constituted in a 90% by hydroxyapatite crystals forming "prisms" and the interprismatic substance that surrounds them. Prisms present different shape according to the species. In some regions they are organized in parallel (Hunter-Schreger bands), and in others in a crisscross way. There is little information regarding the dog, so the aim of this study was to determine the ultramorphology of dog enamel by scanning electron microscopy (SEM). A total of 24 permanent healthy dog teeth were selected. They were cut with a diamond disc and the cut surface was etched with phosphoric acid. The teeth were processed to be studied with the SEM, and the prisms thickness was measured at different sites of the enamel. Dog prisms presented hexagonal shape, and an average thickness of 4,4 μm. Regions with Hunter-Schreger bands, and regions with cross prisms were found. In conclusion, prisms thickness of dog enamel does not vary according to the type of tooth or sector of the crown, except in the cusps where it is narrower. Prismatic organization was similar to that reported in previous dog enamel studies.
