ABSTRACT
With the advent in the technology, accurate examination techniques, especially for delicate structures in the oral and maxillofacial regions are required over conventional x-rays, which are mere 2D (2-dimensional) representations of the 3D (3-dimensional) oral structures. Hence, a radiographic tool with a 3D presentation like that of CBCT (Cone beam computed tomography) technology is preferred in pre- and post-treatment assessment of periodontal defects & implant placements.CBCT technology has been used for almost 2 decades, but was previously more expensive to be used in routine dental practice. Recent developments in this field have made its use more practical in routine dentistry.This literature review, emphasizes the invent, development, working, uses, benefits & limitations of dentascan when used in Periodontics.
