The Salivary pH measured
The saliva samples were obtained at 10-12 a.m. from all children. The saliva was collected into plastic cylinders and the salivary pH was measured with a pH meter (Compact pH meter B-212 twin pH, HORIBA, Osaka, Japan).
The saliva flow rate was measured
The saliva flow rate was estimated by during the first 30 s of paraffin chewing. The saliva was collected into plastic cylinders for a period of 5 minutes. Afterward, the saliva were weighed with a in a precision balance (Mettler PC 400, Zurich, Switzerland) and the flow rate was computed in gms/ml.
Streptococcus mutans and Lactobacillus counts in saliva were measured
The saliva samples were obtained according to described above. Numbers of colony-forming units (CFU) of S. mutans were counted on TSY20B agar and Lactobacilli were counted on Rogosa agar.
