Comparison of clearing techniques: experimental study

Abstract

Dental diafanization is a great ally when studying internal anatomy because through its procedure it allows the teeth to be demineralized and made transparent in order to observe their canals. Understanding this idea, the present research has the objective of comparing the different diaphanization techniques, using multiple chemical compounds to demonstrate which is the most effective technique, the one that offers the lowest cost and time, and to contribute to dental students in their training. The techniques used in this study were those of Robertson, Venturi and Okumura-Aprile. The substances used were: sodium hypochlorite, nitric acid, alcohol of different concentrations, methyl salicylate, India ink, unflavored gelatin, among others. The sample consisted of 28 extracted molars, both maxillary and mandibular, which did not present caries, fractures or root resorption. The result was that when the techniques were submitted under equal conditions and in a controlled environment, the technique that yielded the best results was the Robertson technique, since it provided greater transparency with less cost and time.  It was concluded that through the use of diaphanization, students will obtain a better development in their academic practices.
