Results on deciduous teeth emergence in a cross-sectional sample of Tunisian children from 2 to 36 months are reported. Total tooth number was counted in 1183 males and 1434 females, stratified in 5 social classes. The relation­ship between age and number of emerged teeth was investigated using linearized logistic regressions, by means of an iterative least square proce­dure. Sex and social class show no statistically significant influence on age of tooth emergence. Also not significant is the effect of the interaction of sex and social class. Estimates of chronological age from tooth count have a large amount of uncertainty, making this age-estimating criterion valuable only for a broad classification of children by age.
