Vitality of the periodontal ligament (PDL) is necessary for a successful healing after replantation of exarticulated teeth. In the present investigation newly extracted teeth from monkeys were stored in saline, milk or saliva for 1-3 h. Freeze sections were made and the vitality of the PDL was determined histochemically. Milk seemed to provide better storage conditions than saliva or saline.
牙周韧带（PDL）的活力对于脱臼牙再植后的成功愈合至关重要。在本研究中，从猴子身上新拔除的牙齿分别保存在生理盐水、牛奶或唾液中1 - 3小时。制作冰冻切片，并通过组织化学方法测定PDL的活力。牛奶似乎比唾液或生理盐水提供了更好的保存条件。
