Bone densitometry is an extraordinary clinical and research tool. Most of us think of densitometry as a relatively recent technological development, but in fact, its history began over 100 years ago. In the fi eld of dentistry, crude devices by today’s standards were developed in the late nineteenth century to evaluate the density of the bone in the mandible. The advances in technology continued, albeit slowly for the fi rst half of the twentieth century, gaining some speed in the 1960s and 1970s.
