Endodontic Imaging

With rapid advancement in sensor technology and frequent software upgrades occurring on a regular basis, selection of one system over the other for a specific diagnostic task seems to be challenging. Three-dimensional imaging will continue to be used extensively as sensor characteristics improve and more robust software is introduced.As bit-depth and spatial resolution of images increase, 3D imaging will find more applications in endodontics. TACT is currently a research tool but holds promise of delivering a reliable imaging modality. More studies are still in order using high-resolution sensors for basis image capture, for diagnostic tasks in endodontics. CBCT or VCT provides a significantly faster image acquisition and reconstruction scheme, but the resolution is still inferior to that achieved by TACT. Lack of distortion, magnification, artifacts associated with conventional radiography, and the relative low radiation dose in comparison with medical-grade CT will result in more clinicians adopting such technology to enable accurate diagnoses and treatment planning, in addition to long-term follow-up and evaluation of healing.
