What is CBCT :
CBCT or Cone Beam Computed Tomography is an advanced diagnostic imaging modality of Dental and Maxillofacial Radiology , based on computed tomography that utilizes a single rotational cone beam of xray to render 3D multiplanar images of teeth , jaw bones and adjacent vital structures of head and neck region, by reconstruction from a series of 2D projections, at reduced exposure time and lower radiation dose than medical CT .
The CBCT imaging has not only eased and improvised the diagnosis of dental & maxillofacial pathologies , but has also lead to better treatment planning for a wide range of clinical applications .
Benefits of CBCT over Medical CT :
. Conical Xray beam for volumetric data acquisition in solitary rotation
. Limited area of Exposure by selecting a particular Field of View (FOV ) related to the area of interest
. Improved Accuracy and Diagnostic image quality
. Rapid scan time
. Reduced Radiation dose
. Decreased Image Artifacts
. Less expensive and compact machinery
Various indications of CBCT in dentistry are :
. Implant planning
. Dental and Maxillofacial pathosis
. Trauma cases
. TMJ , ENT and Airway space evaluation
. Dental / Endodontic or Periodontal Status evaluation
. Soft tissue Calcifications of head and neck region
. Assisting in 3D printing / Surgical guide fabrication
CBCT at PDCH Udaipur :
The facility of CBCT , the first to be installed in any Private Dental College in Rajasthan , is available at the Dept. of Oral Medicine and Radiology , Pacific Dental College and Hospital , Debari , Udaipur. The scans are performed on Carestream CS 9300 machine with FOV from 5X5 to 17x13.5 and voxel size from 0.09 to 0.500 mm.
