Effectiveness of a mouth rinsing function test for evaluating the oral function of children

MRFT is effective for evaluating the oral function of children because the MRFT score increases with age. The MRFT score is related to eating behavior; hence, children with low MRFT scores should be supported appropriately. MRFT was not correlated with occlusal force or the thickness and length of the masseter muscle; therefore, it is necessary to examine the oral dexterity, using MRFT, when evaluating the oral function of children.
