Tooth mobility at loads below 100 p, gingival fluid amounts and bone score heights were studied in five subjects. In all 28 maxillary anterior teeth were investigated during a period of 68 weeks. In order to enlarge upon a previous investigation of tooth mobility following periodontal surgery (Persson 1980), the effects on tooth mobility of gingivectomy and flap procedures were compared. A split-mouth technique was used for the two surgical procedures which were performed during one session. No preoperative differences of the investigated parameters were found. During the first weeks after surgery, an increase of tooth mobility was seen which amounted to +80% maximum (flap side) and +13.1% (gingivectomy side). The final tooth mobility changes were -60% on the flap side and -40% on the gingivectomy side. No significant differences of tooth mobility were found between the two surgical methods. The present findings of tooth mobility following surgery also indicated a considerable time lapse before any major decrease of tooth mobility took place.
对5名受试者在负荷低于100 p时的牙齿移动性、龈沟液量和骨评分高度进行了研究。在68周的时间里，共对28颗上颌前牙进行了调查。为了进一步研究牙周手术后的牙齿移动性（Persson，1980年），比较了牙龈切除术和翻瓣术对牙齿移动性的影响。采用分口技术进行这两种手术，手术在一次就诊时完成。未发现所研究参数的术前差异。术后最初几周，观察到牙齿移动性增加，最大增加量为80%（翻瓣侧）和13.1%（牙龈切除侧）。最终牙齿移动性的变化在翻瓣侧为-60%，在牙龈切除侧为-40%。两种手术方法之间未发现牙齿移动性的显著差异。目前关于手术后牙齿移动性的研究结果还表明，在牙齿移动性出现任何显著下降之前，有相当长的时间间隔。
