Cl inic study of the treatment outcome of skeletal classⅡmaloclcusion using the peer assessment rating index
Abstract：Objective To evaluate the outcome of the patients with skeletal class Ⅱ malocclusions treated by extraction or non-extraction through the occlusions assessing .Methods The post-reatment dental casts of two groups of adolescence patients with skeletal class Ⅱmalocclusions treated by extraction or non-extraction respectively were collected.The PAR index were measured on dental casts quantitatively .The PAR score were analyzed to com-pare the dental-occlusion difference between the two groups .Rseults After treatment , the weighted overall PAR scores was (0.62 ±0.74) in extraction group and (0.90 ±1.37) in non-extraction group and there was no signifi-cantly different between two groups ( P>0.05 ) .The other PAR scores were all low and showed no statistical differ -ences between two groups(P >0.05).Conclusion Evaluating from the dental-occlusion,both extraction and non-ex-traction treatment can achieve successful results .
