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.
