Table 3

Univariate Poisson regression analysis between salivary parameters and presence of dental hypersensitivity.

Salivary parameters	Without DH mean (SD)	With DH mean (SD)	PR (95% CI)
Salivary flow rate (mL/min)	0.49 (0.27)	0.66 (0.31)	2.56; (1.28 to 5.12)	0.008
Calcium concentration (g/mL)	194.9 (61.6)	182.1 (40.8)	1.00; (0.99 to 1.01)	0.404
Phosphate concentration (mg/mL)	1.16 (0.33)	1.16 (0.25)	1.01; (0.33 to 3.07)	0.988
Initial pH	7.42 (0.28)	7.45 (0.36)	1.23; (0.39 to 3.89)	0.725
Total buffer capacity; (mL HCl 0.01 N)	1.31 (0.31)	1.33 (0.39)	1.08; (0.39 to 3.03)	0.879
Buffer capacity in each pH range; (mL HCl 0.01 N)
pHi-7.0	0.34 (0.24)	0.32 (0.24)	0.84; (0.18 to 3.87)	0.827
6.9–6.0	0.60 (0.19)	0.63 (0.27)	1.42; (0.31 to 6.52)	0.836
5.9–5.0	0.38 (0.10)	0.38 (0.09)	1.10; (0.03 to 38.86)	0.958

DH = dental hypersensitivity; PR = prevalence ratio; 95% CI = 95% confidence interval; SD = standard deviation.
