Acesso endodôntico em dentes anteriores: uma nova abordagem

Abstract

The teeth Coronary opening is the first stage of an endodontic treatment, being one of the most important stages on the treatment, aiming the direct access to the root canals. In general, by the anterior teeth, the endodontic approach is performed on the palatal/lingual surface of the teeth, more specifically in the dental cingulum, however, the absence of observation on the position of the teeth, can lead to incidents and complications, such as oral perforations, occasioning serious aesthetics damage and harming the whole treatment. The objective of this study is to evaluate a new approach to perform the coronary opening in anterior teeth, regarding the wast on the dental crown, to minimize the risks of perforations incidents, and mainly, to evaluate the ease of execution of new techniques. Altogether, took part 10 students of the Endodontics Improvement course, therefore 20 artificial central incisors teeth were used, each participant made two coronary openings, firstly, the so called “group A” (Conventional Technique) made it without any instruction, afterwards they performed a new opening, however with instructions, and the spherical drill was positioned parallel to the long axis of the tooth, this was nominated the “group B” (Modified Technique). The results had shown that 90% of the participants considered the Modified Technique as the lowest risk of accidents and also the easiest to locate the pulp chamber. There was a statistical difference both for the measurement of the total wear area and for the width, while in height there was no statistical difference. It was concluded that the results collected by the questionnaire are satisfactory results for the modified technique, and also, statistically, the opening modified coronal opening technique shows favorable difference in relation to the wear area and width, while height does not present statistical difference between the Conventional Technique and the Modified Technique.
