【Abstract】 Objective To study the relation tetween the third molar development and skeletal maturity.Methods The material for the present study,consisted of 589 panoramic radiographs accompanied with 589 left hand-wrist radiographs (aged-8～15).The size of samples was determined by staticstivians.Results There are low correlations between the level of skeletal maturation and the third molar development (male:r=0.3719,female:r=0.3958).Conclusion The result suggests that when we study the relationship between the dental age and the steletal maturity,we should not includ the third molar.更多还原
