At the beginning of a 2-year clinical study patients were subjected to five different periodontal surgical procedures. The oral hygiene of 50 test patients was then maintained by professional cleaning at intervals of 2 weeks. Patients in the control group (n = 25) were recalled only once per year for scaling and polishing. In the test subjects further periodontal destruction was arrested; in the control group inadequate plaque control led to progressive periodontitis. Further study, over 4 years, of the test subjects demonstrated that continued vigorous plaque control measures maintained their periodontal status. These results were obtained irrespective of the type of surgery performed initially.
在一项为期两年的临床研究开始时，患者接受了五种不同的牙周外科手术。随后，50名试验患者的口腔卫生通过每两周一次的专业清洁来维持。对照组（n = 25）的患者每年仅被召回进行一次洗牙和抛光。在试验对象中，进一步的牙周破坏得到了控制；在对照组中，菌斑控制不足导致了牙周炎的进展。对试验对象进行的为期四年的进一步研究表明，持续有力的菌斑控制措施维持了他们的牙周状况。无论最初进行的手术类型如何，都获得了这些结果。
