OBJECTIVES: Mandibular bone height and density were compared with age, sex and the number and type of functional dental units, as represented by Eichner index.MATERIAL AND METHODS: A sample of 150 elderly patients of the Dental Clinic were divided into three age groups, examined and orthopantomograms/OPG/ taken.The OPGs were taken with the copper stepwedge in order to enable computer-assisted calculation of mandibular optical density and calibration of dimensional measurements by specially designed software.RESULTS:Eichner class III was found in 62% of patients.The presence of functional units was positively correlated with age (r=0.67) and bone height values (r=0.88,p<0.05).Optical density and bone height values of measurements performed at the same locations on
