Abstract：AIM:To compare of the tooth size discrepancies between Class Ⅱ1 and Ⅱ2 malocclusion. METHODS:120 casts of ClassⅡdivision 1 and Class II division 2 malocclusion were included.Mesio-distal width of the teeth was measured and Bolton Index was calculated.Statistical analysis was made between the 2 groups. RESULTS:1.The sum of anterior tooth width and the sum of total dentition width were not significantly differenct be-tween the 2 groups(P >0.05)of in the male,but were significantly different in the females(P <0.05).2.There was no significant difference of the Bolton index between the two groups(P <0.05).CONCLUSION:Tooth size discrep-encie in maxillary and mandibular can be one of the factors resulting in deep overbite and overjet of Class II malocclu-sion.
