The Impact of Dental Environment Stress on Dentition Status, Salivary Nitric Oxide and Flow Rate.

enic bacteria, subjective oral dryness and unstimulated salivary flow were connected with stress so decrease the protective functions of saliva increasing the vulnerability to dental caries.[ 18 ] Although a lower unstimulated salivary flow rate was found in the severe stress group, this difference did not reach statistical significance; same result was found by other studies.[ 19 ] This is because anxiety and fear may influence salivary flow through pathways in the amygdala, the hypothalamus, and the brain stem.[ 20 ] The salivary flow rate was negatively correlated with caries experience among students with severe stress level.
