Primary Outcome Measures:
  • dental plaque PH [ Time Frame: 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 Outcome Measures:
  • maximum pH drop [ Time Frame: 5,10,15,20 and 30 min after sucrose chalenge ]
  • pH recovery time [ Time Frame: within 30 min after sucrose challenge ]
    time for returning to the baseline pH
