Predepositional, but postmortum tooth erosion has modified its original mor- phology, resulting in the elimination or exaggeration of certain features. The labial and lingual crown face shows evidence of strong erosion, particularly at the crown foot. Both mesial and distal cutting edges are smooth, lacking former weak ser- rations. Foramina, particularly the CLIF, are enlarged and the lingual transverse groove connecting the transverse notch to the CLAF is mesodistally and apically expanded. The lingual longitudinal ridge has been rounded and is not as pro- nounced. The basal edge of each root lobe has been rounded and shortened. Exposed dental osteons on all root surfaces are further evidence of strong Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Southern California Academy of Sciences.
