Differential utilization of proteins in saliva from caries-active and caries-free subjects as growth substrates by plaque-forming streptococci.

abstract：:The experiment was designed to determine the pathway taken to the brain stem by periodontal afferents responsible for the digastric jaw-opening reflex induced by tooth-tapping. Cutting the trigeminal sensory roots of anesthetized decerebrate cats eliminated the ipsilateral periodontally-induced reflex, although the st...
