Performance of cone-beam computed tomography filters for detection of temporomandibular joint osseous changes

Influence of Cone‐Beam Computed Tomography filters on diagnosis of simulated endodontic complications

“…The performance of CBCT filters has been tested for detection of temporomandibular joint osseous changes (Verner et al 2014), peri-implant dehiscence (Vaz et al 2013), condyle defects (Bastos et al 2013), root resorptions (Vaz et al 2012) and root fractures (Wenzel et al 2009, Nascimento et al 2014, Ferreira et al 2015. However, there is a lack of information on CBCT filter performance in detecting several endodontic complications, justifying the importance of the present study.…”

“…The use of a filter can compensate images, despite quality losses caused by elevated noise values as a result of the insufficient radiation dose and detection of large amounts of scattered radiation, and other inter‐related factors such as voxel size, voltage peak and filtration, anode current, exposure time, degree of rotation and FOV (Verner et al . ).…”

“…In order to improve image quality and diagnostic value of CBCT examinations, software tools such as image filters might be used to visually enhance aspects not apparent in its original form, and thereby make vital diagnostic information visible to the human eye (Vaz et al 2013). The use of a filter can compensate images, despite quality losses caused by elevated noise values as a result of the insufficient radiation dose and detection of large amounts of scattered radiation, and other inter-related factors such as voxel size, voltage peak and filtration, anode current, exposure time, degree of rotation and FOV (Verner et al 2014).…”

Análise da aplicação de filtros de realce de imagem no diagnóstico de alterações patológicas da cabeça da mandíbula em exames de ressonância magnética e tomografia computadorizada

“…Verner et al (2014) utilizaram filtros para avaliação de alterações das corticais ósseas (esclerose óssea) na ATM por meio do exame de TCFC. A utilização dos filtros Sharpen (F1) e Angio_Sharpen_Low 3x3 (F2) produziram imagens com excelente qualidade em comparação com o filtro Angio_Sharpen_High 5 x 5 (F3) que não apresentou bons resultados.…”
