摘　　要：目的:建立大鼠咬合创伤动物模型,观察创伤后大鼠行为学及营养状况变化。方法:将直径0.5mm方丝粘固于大鼠左侧上颌第一磨牙,造成对牙合牙的创伤。粘固一个月内观察大鼠行为学及体重变化并拍摄上下颌磨牙根尖片。结果:咬合创伤后大鼠体重增长低于对照组,反应敏感性降低,X线片显示创伤牙牙周膜增宽,牙槽骨吸收。结论:咬合创伤使大鼠产生行为学变化,并抑制体重增长。objective: To establish an animal model of traumatic occlusion in the rat and observe their changes on activity and nutrition. Methods: The occlusal surface of the left first maxillary molar was raised 0.5mm with the square steel. The changes on behavior were observed and x-Ray photos of the molar were taken. Results: Body weight gain in traumatic group was significantly lower than that in control group. Abrasion and widen periodontium ligament were detected on x-Ray photos. Conclusion: Occlusal trauma effected behavior and suppress weight gain of rats
