Computed Tomography (CT)

Computed Tomography, commonly referred to as CT, utilizes X-rays to create detailed cross-sectional images of the anatomical structures. Since its introduction in 1972 by Sir Godfrey N. Hounsfield, CT has significantly impacted medical and dental imaging. In dentistry, CT scans are instrumental in evaluating complex cases involving the jaw and facial bones. They provide invaluable information on the morphology and pathology, assisting in accurate diagnosis and treatment planning. CT’s ability to show three-dimensional structures in high detail makes it unparalleled for assessing buccolingual and mesiodistal extent of pathologies.

Cone Beam Computed Tomography (CBCT)

Cone Beam Computed Tomography, or CBCT, is a variation of traditional CT tailored for dentistry with the added benefit of lower radiation doses compared to conventional CT scans. CBCT offers a three-dimensional view of dental structures, soft tissues, nerve paths, and bone in the craniofacial region with a single scan. This technology surpasses conventional X-rays by providing detailed images that are critical for the diagnosis and management of various dental issues, such as implant planning, evaluation of jaw diseases, and complex endodontics. The success of CBCT lies in its capacity to measure the density of lesions, differentiate between cysts and granulomas, and detect periapical lesions and fractures that might not be visible on traditional radiographs.

Magnetic Resonance Imaging (MRI)

Magnetic Resonance Imaging, or MRI, employs a powerful magnetic field and radio waves to generate detailed images of the internal structures without the use of radiation. In dentistry, MRI is invaluable for imaging soft tissues such as the TMJ (temporomandibular joint), muscles, and ligaments. It’s particularly advantageous for diagnosing TMJ disorders, assessing soft tissue pathology, and planning surgical interventions where detailed soft tissue contrast is crucial. MRI’s non-invasive nature and absence of ionizing radiation make it a safe choice for soft tissue evaluation in the dental field.
