Cone-Beam Computed Tomography for Detection of Intrabony and Furcation Defects: A Systematic Review Based on a Hierarchical Model for Diagnostic Efficacy.

Abstract

The aim of this review is to assess the diagnostic efficacy of cone-beam computed tomography (CBCT) for the diagnosis of and/or treatment planning for intrabony and furcation defects, using a well-known six-tiered hierarchical model for diagnostic efficacy. The MEDLINE, EMBASE, and Cochrane Library bibliographic databases were searched until August 2015 for studies evaluating CBCT imaging for the diagnosis of and/or treatment planning for intrabony and/or furcation defects. The search strategy was restricted to English language publications using the combination of MeSH terms, free terms, and key words. The search strategy yielded 16 publications that qualitatively or quantitatively evaluated the use of CBCT for the detection of intrabony and/or furcation defects and how CBCT influenced the diagnosis and/or treatment plan. According to Quality Assessment of Studies of Diagnostic Accuracy-2, all included studies were medium to low risk of bias. The review identified only one study that investigated the societal efficacy, and none evaluated the patient outcome efficacy or therapeutic efficacy. One study investigated the diagnostic thinking efficacy. All other included studies investigated the diagnostic accuracy of CBCT. From the assessed studies, it can be concluded that there is not sufficient scientific evidence to justify the use of CBCT for the diagnosis of and/or treatment planning for intrabony and furcation defects. Furthermore, the effectiveness of CBCT for such diagnostic tasks has been assessed only at low diagnostic efficacy levels.
