A study was conducted to evaluate using SEM the earliest events of initial blood clot formation on periodontally diseased root surfaces given various treatments. Six teeth with periodontal disease were extracted from six different subjects and were studied in two individual groups. In the first group the root surfaces were divided into three individual treatment areas: (a) intact periodontal ligament, (b) planed, (c) planed and also treated with 1% citric acid. The root surfaces in the second group were likewise divided into three treatment areas: (a) intact periodontal ligament, (b) planed, (c) planed and topically conditioned with tetracycline HCl. All the roots were reinserted into the original extraction sites, and then removed at either "zero" (less than 5 s), one or 3 min and prepared for SEM evaluation. It was observed that organized clot formation occurred more rapidly in the treatment areas where both root planing and topical conditioning with tetracycline HCl had been done.
进行了一项研究，以评估使用扫描电子显微镜（SEM）观察在接受各种治疗的牙周病牙根表面上最初形成血凝块的最早事件。从六个不同受试者中拔出六颗患有牙周病的牙齿，并将其分为两个独立的组进行研究。在第一组中，牙根表面被分为三个独立的治疗区域：（a）完整的牙周膜，（b）刮治，（c）刮治并还用1%柠檬酸处理。第二组中的牙根表面同样分为三个治疗区域：（a）完整的牙周膜，（b）刮治，（c）刮治并用盐酸四环素进行局部预处理。所有牙根均重新植入原拔牙部位，然后在“零”（小于5秒）、1分钟或3分钟时取出，准备进行扫描电子显微镜评估。观察到在同时进行了牙根刮治和用盐酸四环素进行局部预处理的治疗区域中，有组织的血凝块形成发生得更快。
