  1. SD standard deviation, SFR stimulated salivary flow rate, UFR unstimulated salivary flow rate.
  2. aAnalysis of variance and Tukey’s paired comparison test were used to compare the mean values among the three groups.
  3. bResults were obtained using a two-sided chi-square test (two-sided). Statistical significance was set at a p < 0.05. ***p < 0.001.
  4. Significant values are given in bold.
