To compare a tapered filament toothbrush (TFTB) to a control toothbrush (ADA) in their potential to cause gingival abrasion and improve the gingival condition following a period of experimental gingivitis.
Thirty-two subjects refrained from brushing mandibular teeth for 21 days. During a subsequent 4-week treatment phase, the left or right side of the mouth was brushed with either the TFTB or ADA as randomly allocated. Gingival abrasion, plaque and gingival bleeding were assessed.
During the treatment phase gingival abrasion showed a trend to be lower with the TFTB than the ADA, which was significant at the 2-week assessment. The mean plaque scores changed from 2.98 (day 21) to 1.59 for the TFTB and from 3.00 (day 21) to 1.31 for the ADA. The mean bleeding scores changed from 1.86 (day 21) to 1.35 for the TFTB and from 1.85 (day 21) to 1.20 for the ADA. Plaque and bleeding scores were significantly lower with the ADA.
Both toothbrushes improved gingival health and effectively removed plaque. Although there was a tendency towards fewer sites with gingival abrasion with the TFTB brush, it was less effective than the ADA in the removal of plaque biofilm and reduction of bleeding. Subjects considered the TFTB to be more pleasant to use.
比较锥形刷毛牙刷（TFTB）与对照牙刷（ADA）在导致牙龈磨损方面的可能性，以及在一段实验性牙龈炎后改善牙龈状况的能力。
32名受试者下颌牙齿21天不刷牙。在随后为期4周的治疗阶段，按照随机分配，用TFTB或ADA刷口腔的左侧或右侧。评估牙龈磨损、牙菌斑和牙龈出血情况。
在治疗阶段，TFTB导致的牙龈磨损有低于ADA的趋势，在2周评估时差异显著。TFTB的平均牙菌斑评分从2.98（第21天）变为1.59，ADA的从3.00（第21天）变为1.31。TFTB的平均出血评分从1.86（第21天）变为1.35，ADA的从1.85（第21天）变为1.20。ADA的牙菌斑和出血评分显著更低。
两种牙刷都改善了牙龈健康并有效清除了牙菌斑。尽管TFTB牙刷导致牙龈磨损的部位有减少的趋势，但在清除牙菌斑生物膜和减少出血方面不如ADA有效。受试者认为TFTB使用起来更舒适。
