Apart from children of lndian descent having significantly f ewer incisor teeth erupted at one year compared to the four other grou ps, there were no significant differences in canine and molar eruption times among the children. This paper defines primary tooth eruption a ges in South African children for anthropological, clinical and forens ic use.
