There was the same observation period (9 10 years old) in the two groups, therefore their results could be combined to analysis with mixed longitudinal methods. All data were analysed with SPSS 8.0 software.Results:Generally,Ar Po and Go Po increased significantly ( P 0.05 ).Conclusion:In mixed dentition, the mandibular depth growth is greater than its height growth in children with normal face.
