The morphological study of the chondrichthyes teeth represents an important taxonomic characteristic used for the classification and identification of different species. The teeth of four different species of selacimorphs (Carcharhinus leucas, Galeocerdo cuvier, Rhizoprionodon longurio and Sphyrna sp.) were diaphonized in order to standardize a dental technique for their transparency. By standardizing the Okumura-Aprile technique applied for the dental diaphonization of humans, an optimal diaphonization was obtained in the four species treated with 7 % HCl where the pulp chamber was clearly observed. Therefore, we may conclude that the Okumura- Aprile technique is efficient in shark dental diaphonization.
