A double-blind experiment was performed to test the possible prophylactic effect of the antifibrinolytically active propylic ester of p-hydroxybenzoic acid (PEPH) on alveolitis sicca dolorosa (dry socket). Tablets containing PEPH or placebo were inserted at random selection into the alveoli of forty-five consecutive patients, each of whom had had an impacted mandibular third molar removed. The prophylactic effect of PEPH in this study was found to be highly significant as compared to that of placebo, and no patients in the experimental group developed alveolitis sicca dolorosa.
进行了一项双盲实验，以测试对羟基苯甲酸的抗纤维蛋白溶解活性丙酯（PEPH）对干性牙槽炎（干槽症）的可能预防作用。将含有PEPH或安慰剂的片剂随机插入连续45例患者的牙槽中，这些患者均拔除了下颌阻生第三磨牙。与安慰剂相比，本研究发现PEPH的预防作用非常显著，实验组中没有患者发生干性牙槽炎。
