Eighty patients, having received periodontal therapy previously, were divided into four groups, corresponding to one of four different types of dental floss being used. Seven to ten days after receiving a thorough prophylaxis, each patient had oral hygiene instruction by video tape, was given a toothbrush and a quantity of the test floss. At 0, 28 and 56 day intervals, the patients were scored for crevicular fluid flow and gingival bleeding. Data were analyzed statistically. Johnson and Johnson unwaxed dental floss was found to be slightly less effective in reducing gingival bleeding at the 56th day. It was also found that crevicular fluid flow was least with waxed floss use at the 56 day session. However, the range of variations was so minimal that no clinical significance could be ascribed to either finding. There were patients in each of the four floss groups with no fluid flow or bleeding during all three sessions.
80名曾接受过牙周治疗的患者被分为四组，分别对应使用四种不同类型牙线中的一种。在接受全面的牙齿清洁预防措施7至10天后，每位患者通过录像带接受口腔卫生指导，并获得一支牙刷和一定量的测试牙线。每隔0、28和56天，对患者的龈沟液流量和牙龈出血情况进行评分。对数据进行统计分析。结果发现，强生无蜡牙线在第56天时减少牙龈出血的效果略差。还发现，在第56天的测试中，使用有蜡牙线时龈沟液流量最少。然而，变化范围非常小，以至于这两个发现都没有临床意义。在所有三个测试阶段中，四个牙线组中的每组都有患者没有龈沟液流量或牙龈出血。
