Database of Tooth Formation Ages
Collected data consisted of previously reported means for tooth formation ages: a) cusp initiation (ci); b) crown completion (cc); and c) apex completion (ac). This data was originally collected for the crowns and roots of both upper and lower first molars, lateral incisors, central incisors, and canines. These were calculated from measurements on more than 10,000 individuals from across the different studies and from different world regions. Collected data and summary calculations are given within the same file in separate sheets. For collected data we report the original mean and standard deviation for ci, cc and ac according to tooth type and sex (male, female, unreported). Within the collected data sheet we also identify the target population on which the study was made and provide the bibliographic references. We summarized this data by reporting weighted means and standard errors, weighted by the standard deviations given in the original data.
