title: Three-month change in the radiodensity of alveolar bone supporting partial-denture abutment teeth.
abstract: This study uses the intraoral microdensitometric method to examine the impact of masticatory pressure on the alveolar bone around the abutment teeth clasp. Two retroalveolar radiographs were carried out on all 30 subjects over a period of 3 months using a copper calibration stepwedge. The dental radiographs were digitized and converted into positive. Grey level values on dental radiographs in the alveolar bone area in 7 region of interest (ROI) were measured. They were converted into the equivalent thickness of the calibration stepwedge using mathematical methods and the difference of the bone density between the two radiographs was calculated. The results demonstrated that there were no statistically significant differences between the 1st and 2nd radiographs in any of ROI (p > 0.05).
