Resumo: O diagnóstico por imagem é um exame complementar importante para o diagnóstico e acompanhamento da doença periodontal e peri-implantar e atualmente a tomografia computadorizada de feixe cônico (TCFC) substitui o uso das tomografias convencionais odontológicas e da tomografia computadorizada médica. No entanto, artefatos ocorrem principalmente, próximos de estruturas de alta densidade como o metal, sendo que essa alteração pode interferir na interpretação das imagens e no diagnóstico. Sendo assim, o presente estudo tem como objetivo realizar uma revisão de literatura relacionada ao efeito do artefato de “beam hardening” na capacidade de identificação das alterações periodontais e peri-implantares. Conclui-se que a TCFC promove uma avaliação tridimensional de doença periodontal e da peri-implantite, mas na presença de artefatos metálicos pode haver uma limitação da qualidade da imagem do nível ósseo ao redor dos dentes e implantes.

Palavras-chave: Tomografia Computadorizada de Feixe cônico; Artefato; Diagnóstico; Nível ósseo.

 

Abstract: Diagnostic imaging is an important complementary method for the diagnosis and follow up of periodontal disease and peri-implant and nowadays cone-beam computed tomography (CBCT) replaces the use of conventional dental CT scans and medical CT scan. However, artifacts occur mainly near high-density structures such as metal, and this change may interfere interpretation of the images and diagnosis. Therefore, this study aims to conduct a literature review on the effect of “beam hardening” artifact in identifying capacity of periodontal and peri-implant changes. We conclude that CBCT promote three-dimensional evaluation of periodontal disease and peri-implantitis, but presence of metal artifacts could be a limitation of the image quality of bone level around the teeth and implants.

Key words: Cone-beam computed tomography; Artifact; Diagnosis; Bone level.
