Glucose estimation in the salivary secretion of diabetes mellitus patients

Figures & data

Table 1 Comparison of preprandial salivary glucose between control and patient groups

Group	Mean	SD	t-value
Control	1.23 mg/dL	0.52	3.21**
Patient	4.22 mg/dL	3.59	(P < 0.01)

Note:

** t-value shows statistically significant difference between patient and control.

Abbreviation: SD, standard deviation.

Table 2 Comparison of preprandial salivary glucose by serum glucose (patients)

Serum glucose range	Mean of salivary glucose	SD	f-value
Below 130 mg/dL	2.18 mg/dL	1.29	42.13**
130–200 mg/dL	4.05 mg/dL	2.56	(P < 0.01)
Above 200 mg/dL	8.74 mg/dL	4.50

Note:

** f-value shows statistically significant difference between serum glucose and salivary glucose.

Abbreviation: SD, standard deviation.

Table 3 Comparison of preprandial salivary glucose by glycated hemoglobin (HbA_1c)

HBA1C range	Mean	SD	f-value
Up to 7%	2.30 mg/dL	1.34	15.80**
7%–8%	3.81 mg/dL	3.12	(P < 0.01)
Over 8%	6.72 mg/dL	4.64

Note:

** f-value shows statistically significant difference between preprandial salivary glucose and glycated hemoglobin.

Abbreviation: SD, standard deviation. age groups of patients. Similarly, no significant differences were found when salivary glucose was compared between male and female patients, using an independent t-test (P > 0.05).
