    Técnica de diafanização em dentes humanos
    (2018-02-23) Silva, Beatriz Rayne Moraes Gomes da; Palma, Mariza Brandão; http://lattes.cnpq.br/5056572269695104; http://lattes.cnpq.br/3891961554423682
    Experimental teaching has the role of being an auxiliary resource capable of ensuring the effective transmission of scientific knowledge. Fresh parts and carcasses, although they offer greater fidelity in the reproduction of the structures in vivo, without additional cost and without loss of material in the fixation of the pieces is difficult to obtain and have a very limited durability for the study. With the passage of time, several techniques of preservation of anatomical pieces were developed; and currently various materials can be used for this purpose, such as: formaldehyde, glycerin, ethyl alcohol and phenol. Some techniques are applied in the study of the internal anatomy of the teeth, among them is diaphanization, which is widely used in the endodontic branch. Clearing is a technique that involves treating biological samples to make them semi-transparent. Currently, there are several protocols for applying the method of diaphanization in human teeth. The technique recommended by Okumura allows the three-dimensional visualization of the morphology of the entire root canal system and its ramifications. The objective of this work was to evaluate the technique of diaphanization in human teeth as effective in the study of the internal anatomy of the same and tool in the process of teaching and learning in graduation. A historical and bibliographic survey was carried out on the main techniques of diaphanization used in endodontics. When submitted to these processes, the teeth should have a degree of whiteness, flexibility and fragility. The ink coloration allows a better visualization of the internal anatomy of the root canals of the teeth. The study of the diaphanization technique besides allowing a specific treatment in endodontics against pathologies is a great pedagogical tool in the process of teaching and learning in the academic scope.
