Objectives: To compare the efficacy of different image processing algorithms of three digital x-ray software programs in detecting small artificial approximal caries defects. Methods: 75 extracted human maxillary and mandibular posterior permanent teeth were selected. The 0.5 millimeter diameter high speed diamond bur was used to prepare and simulate small dental caries on proximal surfaces of the teeth. The teeth were mounted in 25 plaster blocks. Each of them contained 2 premolars and 1 molar. A prominent part of proximal surfaces were placed at the same vertical level to simulate normal anatomical contacts. Bitewing radiographs were taken and viewed with Vixwin 200, Dimaxis and Dr. Suni plus. The radiograph was enhanced with emboss, gray-scale reversed and contrast-brightness tools. Three observers assessed the digital radiographs from each.. View More»
