Results of salivary diagnostics

Parameter	Non-DM (n = 93)	DM (n = 66)	Significance level (P)
Unstimulated salivary flow rate (mL/minute)	0.23 ± 0.23	0.16 ± 0.20	0.15
Stimulated salivary flow rate (mL/minute)	0.50 ± 0.40	0.42 ± 0.42	0.20
pH of unstimulated saliva	7.0 ± 0.9	6.7 ± 0.7	<0.01
Buffering capacity of stimulated saliva
Low	56.2	41.2	1.0
Medium	28.1	27.9
High	15.7	14.8

Values are given as mean ± standard deviation or %.

DM, diabetes mellitus; mL/minute, milliliters per minute; non-DM, no diabetes mellitus.

P-values were determined using the Mann–Whitney U-test, and significant results (P < 0.05) are given in bold type.
