ABSTRACT
Objective: To observe the oral care effects of finger toothbrush. Methods: The finger toothbrush worn on the index finger was made of silica gel .It was used to brush the in vitro healthy teeth pulled out on the same day and the standard hard plaster tooth model and to brush the in vivo healthy teeth in adults; the bacteria in the finger toothbrush, The dentofacial pluque and the abrasion on the tooth model were tested respectively. Results: After in vivo use the bacteria remained in the finger toothbrush were fewer than those in the commonly used toothbrush(1 683.24?1 355.59 and 2 353.76?1 582.06 respectively). The dentofacial plaque was decreased in the same extent by the two kinds of toothbrushes. The zero rate of abrasion on the tooth model was 93.3%(28/30) by finger toothbrush and 23.3%(14/30) by the commonly used toothbrush. Conclusion: The finger toothbrush worn on finger can remove dentofacial plaque effectively and produce a lower abrasion on tooth.
