They also evaluated the visualization of lamina dura, crater defects furcation involvements, contrast, and bone quality. In their study, they concluded that CBCT image measurements of periodontal bone level and defects were comparable to intraoral radiography. They also found that CBCT images verified more potential in the morphologic description of periodontal bone defects and conversely, the CCD images provided more bone details. Using a dry skull and by means of artificial defects evaluated by full-volume CBCT, Misch and colleagues9 found similar results.

While measuring the buccal and lingual defects, CBCT proved superior to conventional radiography. The major disadvantage of using CBCT is the radiation dose. Newer machines, have capacity to acquire the images with half of the rotation as compared to the full rotation that was used conventionally. (Fig. 3, 4) Till now, there is no research demonstrating the efficacy by using a smaller rotation arch, but this is the new area of investigation.0
