After carrying out reciprocating brushing 5000 times or 10000 times by using a brush machine, the gap-widening was determined according to the following mathematical Formula 1. As the value of elasticity loss is decreased, the difference of a gap in the bristles between before and after brushing is reduced, suggesting that the toothbrush bristles show lower gap-widening.
