title: On the etiology of interproximal grooves.
abstract: The recent suggestion by Brown and Molnar (1990) that the common etiology of sinew processing is responsible for the production of interproximal tooth grooves is contested. Based on a review of the Australian evidence and presentation of a previously undescribed dentition from Central Europe, it is argued toothpicks are a likely cause of many artificial grooves in human teeth.
