Measure	Time frame
dental plaque PH	the pH of 48-hour dental plaque was measured using plaque sampling method before (baseline pH) and after sucrose challenge at 5, 10,15,20,30 minutes

Secondary

Measure	Time frame	Description
maximum pH drop	5,10,15,20 and 30 min after sucrose chalenge	—
pH recovery time	within 30 min after sucrose challenge	time for returning to the baseline pH
