AVALIAÇÃO DA UTILIZAÇÃO DE TRÊS DIFERENTES INSTRUMENTOS EM CANAIS ARTIFICIAIS CALCIFICADOS NA ENDODONTIA GUIADA

Abstract

Introduction - Pulp calcification implies a high degree of difficulty during endodontic access. In an attempt to locate the channel, there may be deviation from the original route and perforations. To minimize these risks, guided endodontics emerged as a more accurate and safe approach. Methodology - Sixty-six artificial lower central incisors were divided into three groups, according to the instrument used to perform guided access: milling Ø1.3mm of implantology, milling Ø1.0 mm Radiodontic Kit, Ø1.0 mm Kit Endo Guide. They were also distributed in two groups, according to the presence or not of the endodontic guide (n = 11). The guides used were printed through the TCFC association with digital scanning. For the evaluation of the deviation, the digital planning images were overlap with the post-access TCFC in the NemoTec. software. Results - The implantology cutter presented the lowest average deviation with (0.2682 ± 0.12890) in guided access with the washer and (0.4109 ± 0.33399) on non-treat access. When this instrument was compared to the others, there was a variation of the significant deviation only in relation to the Radiodontic cutter, with p = 0.000 in the washer guides and p = 0.003 in the non -treat guides. When the influence of the washer in the guide was related to the deviation, only the Radiodontic washer showed significant difference with p = 0.020. Conclusion - The Ø1.0 mm Radiodontic Kit cutter was the only instrument that presented a significant difference in the comparison of deviation, among the instruments and the assessment of the washer influence on the deviation.
