Parallax radiograph
WebJul 28, 2015 · Parallel radiographs overestimate the actual remain dentin thickness in mesiobuccal canals of maxillary first molars, whereas the parallel technique would give a closer estimate to the actual thickness at a projection angle of about 21°. Peer Review reports Background WebMar 14, 2024 · Parallax radiographic technique depends on a simple concept wherein if the object moves to the same direction of the x-ray cylinder, this indicates that the object is lingually positioned. However, horizontal parallax showed higher sensitivity in locating the canines (88%) in comparison to the vertical parallax (69%) [13, 14].
