• Since movement of the body are controlled by a feedback mechanism of sensations it is reasonable to consider that this mechanism also takes part in controlling toothbrushing.<BR>The present study was started on a suggestion that difference in individual toothbrushing force might be related with a feedback mechanism for the sensations of the oral mucous, periodontal membrane, and of muscles and joints of the arm and hand which held a toothbrush.<BR>Twelve people 21-28 years of age were studied under three conditions, 1) the oral mucous membrane only anesthetized, 2) the oral mucous and periodontal membrane simultaneously anesthetized, 3) neither the oral mucous membrane nor the periodontal membrane anesthetized, as to relations between stiffness of a toothbrush and brushing force in reference to change in sensations in the oral mucous and periodontal membrane.<BR>The results obtained were as follows:<BR>When the oral mucous and periodontal membrane were anesthetized, the use of a soft bristle toothbrush decreased brushing force from 100-1, 100g to 100-700g; the use of a hard bristle toothbrush decreased only from 100-700g to 100-600g.<BR>The above difference in decrease indicated that cutaneous sensations of the oral mucous and periodontal membrane were related with a feedback mechanism governing toothbrushing force when a soft bristle toothbrush was employed or over 700g of force was given, and sensations of the muscles and joints of the arm of hand which held a toothbrush were related when a ard bristle toothbrush was employed or less than 700g of force was given.<BR>Since toothbrushing force which greatly influences plaque removal effect is related with sensation which is a physiological factor very difficult to change, an attempt to increase the plaque removal effect needs a great deal of effort.<BR>The next best requirement would be an attempt to make the brushing force as large as possible, or. to increase the number of brushing strokes (prolongation of brushing time) or to improve radically the present brushing methods. So long as a manual toothbrush is being used, it is almost hopeless to increase the plaque removal effect with the present methods.
