摘    要:
为了探讨He创伤持续时间与牙髓、牙周组织变化间的关系,作者对44只大鼠的下颌磨牙制造了实验性He创伤,利用组织病理学和软射线的研究方法,观察不同实验期受创伤大鼠磨牙的牙髓、牙周组织变化,并与软射线片进行对照分析。结果表明,牙髓组织随He务时间延长而病变逐渐加重;牙周组织受到长期He创伤后呈现适应性变化,牙周组织焦吩一软射线片显示的牙周变化部位相应。本研究结果为He创伤性牙髓炎和根尖周炎的病因,病理

Abstract:
In order to study relationship between the period of occlusal trauma and pulpal and periodontal tissues, 44 rats were used in experimental occlusal trauma. The pulpal and periodontal tissues of rat molars were observed by histological examination and micrographic examination. The results showed that the damage of pulp became more serious as time went on, but periodontium appeared adaptive changes. The same changing area in periodontal tissues were observed between histological section and micrographic film. The results provide experimental evidences for the pathology and pathogeny of pulpitis and perioapical periodontitis caused by occlusal trauma.
