Tooth formation age dataset for early childhood bioarchaeological and medical studies.

We compiled data from histological sources on the formation ages for human mandibular and maxillary permanent first molars, lateral and central incisors and canines. From this we summarised the data by reporting weighted means for cusp initiation, crown completion and apex completion. This provides a reference for bioarchaeological and medical studies investigating early childhood. More specifically, this reference is a crucial element in the study of early childhood nutrition and morbidity from osteological analysis and stable isotope analyses of teeth and their growth increments.
