Abstract
Aiming to elucidate whether the blood glucose level can be estimated from the saliva glucose level or not, this study was made to establish a sampling method of saliva available for the determination of saliva glucose level. Next, 75 gOGTT was carried out in six healthy adults for three days and the time-course changes in the glucose level in blood and saliva and were simultaneously determined. As the results, it revealed that the saliva glucose levels in the normal subjects varied within arange of 1/50∼1/100 of their blood glucose levels. The former level of all subjects was not correlated with the latter with a correlation factor of O.37, but personal correlation factor was O.76± 0.10(mean±SD). The present study demonstrated that there are a positive correlation between the blood glucose level and the saliva one of an identical subject.
