ABSTRACT
Objective To elucidate the relationship between mandibular lateral displacement and mandible asymmetry by observing the morphological changes of condylar head and mandible during mandibular lateral displacement in growing rats.Methods Forty-eight male Wistar rats at the age of four weeks were divided at random into experimental and control groups,with 24 rats in each group.A super-hard resin plate was cemented to upper incisors to displace rat mandibles 2 mm to the left during closure(Ipsilateral side).A metal crown was fitted to lower incisors.The rats were killed 2,4,8 or 12 weeks after appliance attachment.The mandible was dissected out and halved.The length and width of condylar head were measured with a caliper.Radiographic films of the mandibles were exposed,and selected measurements were made.Results The length of condylar cartilage on the ipsilateral side was significantly larger than contralateral side in experimental group(P
