Title Cone Beam Computed Tomography (CBCT) and Multi-slice Computed Tomography (MSCT) Show Equal Ability to Detect the Fine Structures of the Mandibular Nerve
Clinical Question Can we locate the mandibular nerve better with a cone beam computed tomography (CBCT) or with multi-slice Computed tomography (MSCT)?
Clinical Bottom Line The scans of 28 patients who had undergone CBCT and MSCT were compared in 2-D images, and no difference was found in detecting fine anatomical features of the mandibular nerve. (See Comments on the CAT below)

The Evidence
Although the mean time between CBCT and MSCT imaging was 30.1 months, it was considered that the mandibular nerve structures being evaluated did not change during that time. This study agrees with previous studies that both CBCT and MSCT have similair accuracy.
Applicability This was a convenience sample of the 28 (6 males, 22 females) dental implant treatment planning patients who had received both CBCT and MSCT imaging in a Japanese university clinic, for various implant-related clinical indications. Mean age 54.5 years (+/- 10.9 SD).

I conducted a PUBMED search concerning this topic and found the most recent research supports the findings of this CAT. PUBMED article’s: 20123365, 21860924, and 21778080 all concluded that CBCT and MSCT show comparable abilities to detect fine anatomic structures, as well as pathology in the human mandible.
