Resumo: Objective: The aim of this study was to compare, by means of three-dimensional reconstructed images, the validity of multislice computed tomography (MSCT) and cone-beam computed tomography (CBCT) in the diagnosis of simulated mandibular lesions. Methods: Fifteen dry mandibles were perforated using a round bur (diameter of the tip: 1mm) and a high-speed handpiece. The lesions, which differed in dimension, shape and locularity, were produced either in the buccal or lingual cortical bone of the mandibular body. In some cases, the bur just touched the cortical bone, whereas in others, it perforated the medullary bone. Specimens were submitted to CBCT and MSCT. The images were analyzed independently by two experienced examiners using commercially available software (Vítrea®, version 3.4.5; Vital Images Inc., Plymouth, MN, USA) at different sessions according to two protocols: 3D reconstruction of MSCT scans (3D-MSCT) and 3D reconstruction of CBCT scans (3D-CBCT). Results: There were no significant differences between the two protocols regarding the identification of medullary bone involvement or the number of lesions detected. Conclusion: The validity of 3D-CBCT for the identification of the number of lesions and of medullary bone destruction was similar to that of 3D-MSCT.

Métodos: Quinze mandíbulas maceradas foram perfuradas utilizando broca esférica (diâmetro da ponta ativa: 1mm) e caneta de alta rotação. As lesões, que apresentavam diferentes dimensões, formatos e locularidade, foram produzidas no corpo das mandíbulas tanto na cortical lingual como na cortical vestibular. Em alguns casos a broca apenas tocou a cortical óssea, enquanto que em outros, houve perfuração acometendo o osso medular. Os espécimes foram então submetidos à TCMS e TCFC. As imagens foram analisadas de forma independente por dois examinadores experientes utilizando o programa de reconstrução de imagens tridimensionais (Vítrea®, versão 3.4.5; Vital Images Inc., Plymouth, MN, USA) em momentos distintos de acordo com dois protocolos: reconstrução 3D com imagens adquiridas em TCMS (3D-TCMS) e reconstrução 3D com imagens adquiridas em TCFC (3D-TCFC). Resultados: Não houve diferença estatisticamente significante entre os dois protocolos em relação à identificação do envolvimento medular ou do número de lesões ósseas detectadas. Conclusão: A validade da 3D-TCFC para identificação do número de lesões ósseas e do acometimento do osso medular foi similar a 3D-TCMS.EDIPUCRS - Editora Universitária da PUCRS2013-09-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/12599Revista Odonto Ciência; Vol. 28 No. 2 (2013); 47-52Revista Odonto Ciência; v. 28 n. 2 (2013); 47-521980-65230102-9460reponame:Revista odonto ciência (Online)instname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUC_RSenghttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/12599/11858Sales, Marcelo Augusto OliveiraGaia, Bruno FelipePerrella, AndréiaCavalcanti, Marcelo Gusmão Paraísoinfo:eu-repo/semantics/openAccess2014-09-19T18:23:55Zoai:ojs.revistaseletronicas.pucrs.br:article/12599Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2014-09-19T18:23:55Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
