牙体制备时,持续和(或)重度刺激会不可逆地影响成牙本质细胞。诱发急性炎症。纤维蛋白原/纤维蛋白在创伤愈合时形成最早的基质结构,构成机械屏障,纤维连接素也在其中有着重要作用。但牙体制备后,牙本质-牙髓复合体内的纤维蛋白原/纤维蛋白和纤维连接素分布如何,尚不清楚,本文对此进行了研究。 材料和方法 15只成年sprague-Dawley鼠,在其中12只鼠的上颌第一磨牙近中面使用气涡轮机(水冷
Continuous and / or severe irritation can irreversibly affect odontoblasts during tooth preparation. Acute inflammation is induced. Fibrinogen / fibrin forms the earliest matrix structure upon wound healing, forming a mechanical barrier in which fibronectin also plays an important role. However, it is unclear how the fibrinogen / fibrin and fibronectin are distributed in the dentin-pulp complex after tooth preparation, as we have done in this article. MATERIALS AND METHODS Fifteen adult sprague-Dawley rats were used, in which 12 rats were treated with a gas turbine (water-cooled
