Overall literature reviews have concluded that no one design of the manual toothbrush is superior for plaque removal. More recently, a toothbrush with filaments angled away from the head was shown to be more effective in several single‐use studies than conventional designs. The aim of this study was to compare plaque removal by this new toothbrush and 3 other toothbrushes which had more conventional filament arrangements. 36 volunteers participated in this single‐blind, randomised, 4‐cell, crossover single use toothbrushing study On day 1 of each period, volunteers brushed with a standard toothbrush and toothpaste for 60 s and then suspended oral hygiene for 48 h. On day 3, volunteers were scored for plaque by area and then brushed with the allocated test toothbrush with toothpaste for 60 s and plaque area was rescored. A washout of 4 days was allowed between test periods. The plaque areas were used to record the binary scores of the Rustogi et al. modification of the modified Navy plaque index but away from the clinic employing the Claydon and Addy procedural method for the index. Plaque removal scored by area and site were not significantly different between the brushes. This study is at variance with previous similar investigations which suggested that the new design of toothbrush head was superior for plaque removal. It is concluded again that there are no data which demonstrate unequivocally that any one manual toothbrush design is superior to any other for plaque removal.
