Missing Molars & Microdontia

November 19, 2010 By arne hendriks 0

In a 2008 discovery of the remains of small humans (130 – 140 cm) on the Micronesian island of Palau it was observed that the teeth seemed unusually large in comparison to the jaw bone. Discoverer Lee Berger speculates that this is the result of a process of rapid dwarfing. Teeth apparently need more time to shrink then jaw bones. Another consequence of this particular difference in dwarf speed was that in over half the found jaw bones the third molar was found to be missing, simply because it didn’t fit anymore.  If we decide to shrink we need to address these different timetables. For this particular problem perhaps the study of what causes microdontia, the growth of unusually small teeth, is relevant.
