<jats:title>Abstract</jats:title><jats:p>Dental emergence ages are examined for a mixed longitudinal sample of 58 chimpanzees of known age and sex (22 males, 36 females) followed over the past 10 years. This study provides the most complete data set currently available on dental emergence in chimpanzees of known age and sex. Summary statistics and cumulative frequency percentiles of emergence ages are presented for both the permanent and the primary teeth. Male and female percentiles are also compared and reveal a number of cases of sexual dimorphism in emergence ages. Comparisons of emergence means reveal some statistically significant differences between upper and lower teeth but not between antimeres in the upper or lower dentition. Kendall's rank correlation coefficient (tau) suggests a correlation in timing between first molar and incisor emergence within individuals. In addition, a significant time lag was observed between first molar and central incisor emergence. A number of emergence sequence polymorphisms are presented as well. These findings provide important baseline information for future studies of chimpanzee growth, development, and demography and also contribute to several current issues in paleoanthropology relating to dental maturation patterns in early hominids.</jats:p>
