Application of a new CBCT software with specific filters for blooming artifact reduction: case series

Introduction: Root canal fillings and intraradicular posts often create white contrast artifacts and possible volumetric changes on CBCT scans known as blooming artifacts. These alterations could lead to the incorrect interpretations reducing the diagnostic of an acquired CBCT volume, particularly when evaluating potential root fractures and root perforations. Methods and Results: In six clinical cases, the positive and negative effects of beam hardening artifacts on the diagnosis of root fractures, root perforations and porcelain restoration cementation were evaluated. These artifacts, induced by the higher density of root canal filling materials, cements for crown placement and intracanal posts, may potentially lead to inaccurate or false interpretations. A novel software, e-Vol DX, which has specific filters for blooming artifact reduction (BAR), was used to improve the diagnostic value of acquired CBCT volumes. Conclusions: The use of the e-Vol DX software package for the reconstruction of CBCT scans improved visualization of anatomical structures and reduced blooming artifacts. Improved data visualization may help reveal essential details that, in conjunction with clinical findings, are useful to achieve a correct diagnosis.
