Abstract
A detailed eruption sequence and associated age of eruption for deciduous dentition in baboons (Papio sp) are presented in this paper. The sequence was determined by evaluation and comparison of the number and kinds of teeth present in nine age cohorts comprising the study sample of 88 males and 87 females who ranged in age from birth to 763 days. Eruption was assessed visually as present or absent. Several statistical methods used to derive the ages associated with the eruption sequence are described. The basic eruption sequence in the sample population is: i1 i1, i2, i2, \documentclass{article}\pagestyle{empty}\begin{document}$ \mathop {\rm c}\limits_{\rm -} {\rm,}\mathop {\rm c}\limits^{\rm -} $\end{document} m1 (m2, m2), M1, M1. Both sexes show the same pattern, with the exception of the second deciduous molar, where males show a sequence of m2, m2, while females show the opposite. Posterior dentition shows the greatest gender-specific variation in average age of eruption.
