remarkable that in the paleoanthropological material the fre- 

 quency is higher as compared with the recent material, which 

 may be the result of the closed communities of people in early 

 times. It is worthy to note that the palato-gingival groove was 

 more frequent in teeth of skulls with Mongoloid character. 



Sexual dimorphism, symmetry and asymmetry relation- 

 ships, and simultaneous occurrence of the two develop- 

 mental anomalies show no important differences. 



Based on clinical reports and our clinical case herein re- 

 ported, caries and the localized bone lesions in pal- 

 eoanthropological material might have been caused by devel- 

 opmental anomalies (dens invaginatus and palato-gingival 

 groove).
