Techniques for assessing alveolar bone mass changes in periodontal disease with emphasis on 125I absorptiometry

J Clin Periodontol. 1983 Sep;10(5):455-64. doi: 10.1111/j.1600-051x.1983.tb02178.x.


No practical methods are presently available for measurement of alveolar bone activity at one instant of time. However, roentgenological methods making measurements at 2 different times can be used to assess alveolar bone activity. The most sensitive, specific and accurate method for this purpose presently in use is 125I absorptiometry. This method has the further advantage of giving the patient minimal radiation exposure. New methodology is under development which obviates the need for fixed geometry and could provide a 3-dimensional image of alveolar bone.
