Accuracy of enhancement filters in measuring in vitro peri‐implant bone level

Abstract

In addition to the original images, the fine and emboss filters resulted on the most precise measures. The caries1, caries2, endo, and perio filters were the less accurate for measuring the peri-implant bone level.

The ‘Sharpen’ filter improves the radiographic detection of vertical root fractures

“…) and peri‐implant bone level (de Azevedo Vaz et al . ) has been reported. The purpose of this study was to evaluate if digital enhancement filters influenced the diagnosis of root fractures.…”

“…The negative filter reverses the greyness of the image so that what is black becomes white and vice versa (de Azevedo Vaz et al . ). The Sharpen filter was developed with an algorithm that enables computer‐assisted manipulation of the input image data array or matrix, grouping high‐contrast pixels together in a submatrix, thus evidencing subtle changes in the output image (Analoui ).…”

The impact of enhancement filters on radiographic diagnosis of dental caries (Wenzel & Hintze 1993, Sanden et al 2003, Kositbowornchai et al 2004, Haiter-Neto et al 2008, Zangooei Booshehry et al 2010, Bel em et al 2013, bone loss (Eickholz et al 1999) and peri-implant bone level (de Azevedo Vaz et al 2013) has been reported. The purpose of this study was to evaluate if digital enhancement filters influenced the diagnosis of root fractures.…”

“…Both 3D Emboss and Shadow can be used to visualize paths of structures that pass through dark and light regions of an image, such as endodontic files for length measurement, or root fractures and similar pathology. The difference between the Shadow and 3D Emboss filters is that a residual portion of greyscale remains when using the Shadow filter.The negative filter reverses the greyness of the image so that what is black becomes white and vice versa(de Azevedo Vaz et al 2013).…”

Imaging evaluating of the implant/bone interface—an in vitro radiographic study

“…Specific filters for digital radiograph processing can contribute to image evaluation and diagnosis when correctly indicated. 8,[12][13][14] The present research investigated the impact of filter for bone-implant interface evaluation, as radiographs are indicated for post-operative evaluation of dental implants. 1 Enhanced images are preferred among dentists who evaluate digital radiographs.…”
