| 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(he)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。

| Abstract: | 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 |
