Gum could possibly be just as effective as flossing, even though they each target different areas of the mouth. Chewing gum does not remove bacteria from the same places of the dentition as does brushing or flossing.
Dictionary.com defines a passive restraint as âa safety device, as an air bag or special seat belt, that is activated automatically to protect an automobile passenger at the moment of impact when a collision occurs.â Passive restraints are not limited to vehicular safety.
It is similar to the hold-relax technique except that a dynamic or ballistic stretch is employed in place of the final passive stretch. Notice that in the hold-relax-contract, there is no final passive stretch. It is replaced by the antagonist-contraction which, via reciprocal inhibition (see section Reciprocal Inhibition), serves to relax and further stretch the muscle that was subjected to the initial passive stretch.
