Digital Radiographic Images Comparison with Subtraction Radiography in Bone Density Evaluation Around Dental Implants

Background& Objective: The reduction of alveolar crestal bone density is one of the earlier signs of periimplant disease and precedes the loss of height of the alveolar crest, because of that early detection of the small changes in density is important and lead to the early onset of treatment and increases its success's percentage. This study aimed to evaluate the ability of the direct conventional digital method in detection of density changes around dental implants by the mean value of the gray level of the histogram of the selected area comparing with radiographic subtraction method.
