Also generated are percentile graphs for visual evaluations children adolescents. Since scales do not tolerate any missing data, great limitation their use, we have developed linear regression models predicting the formation each It easiest predict stage first molars (correct 87% within study material) most difficult second premolars 69% 70%, respectively). expect data formulae presented this prove useful research clinical forensic dentistry.
