Analyzing Longitudinal Growth Data in Orthodontics

Longitudinal growth data with repeated measurements of distances and angles on radiographs are usually collected to study skeletal and dental changes throughout childhood and adolescence. The analysis of longitudinal data usually requires sophisticated statistical methods and modeling techniques because repeated measurements made on the same subject violate the assumption of independence underlying classical statistical tests. Advanced methods, such as multilevel modeling, must be used to account for the correlations between repeated measurements.
