Keyes' method of non-surgical therapy was compared with modified Widman flap surgery in 9 patients with symmetrical periodontal disease. Following an initial oral hygiene programme, baseline measurements were recorded and paired contralateral areas were subjected randomly to the 2 techniques. 42 teeth receiving surgery were compared with 40 treated by Keyes' method. 6 sites per tooth were scored immediately prior to therapy and 3 months later, using a constant force probe with onlays. Consistent data were recorded for the 6 separate sites, which showed no baseline difference between treatments, slightly greater recession with surgery at 3 months, but no difference between treatments in probing depth and attachment levels. Mean data for individual patients showed similar consistency. Probing depth in deep sites was reduced slightly more with surgery, and there were no differences in bleeding on probing at 3 months. Both techniques gave marked improvements in health. Surprisingly, only 2 subjects preferred Keyes' technique of mechanical therapy, 6 preferred surgery, and 1 had no preference.
在9例患有对称性牙周病的患者中，对凯斯非手术治疗方法与改良威德曼瓣手术进行了比较。在初始口腔卫生计划之后，记录基线测量数据，并将成对的对侧区域随机采用这两种技术进行治疗。将接受手术的42颗牙齿与采用凯斯方法治疗的40颗牙齿进行比较。在治疗前和3个月后，使用带有嵌体的恒力探针对每颗牙齿的6个部位进行评分。对6个单独部位记录了一致的数据，结果显示治疗之间基线无差异，3个月时手术组退缩稍多，但治疗组在探诊深度和附着水平方面无差异。个体患者的平均数据显示出类似的一致性。手术组深部部位的探诊深度降低得稍多一些，3个月时探诊出血情况无差异。两种技术都使健康状况有显著改善。令人惊讶的是，只有2名受试者更喜欢凯斯的机械治疗技术，6名更喜欢手术，1名无偏好。
