Abstract
AIM: To evaluate the change in salivary pH following consumption of different snacks and beverages in pre-school children and also to evaluate their oral clearance time. MATERIALS AND METHODS: For 7 days 7 different types of snacks and beverage were given to the 150 preschool children for consumption. After that pH of saliva was calculated with digital pH meter at various intervals up to 30 min. Data were statistically analyzed by using SPSS version 26. RESULTS: In the 7-day study there is statistically significant change in salivary pH after consumption of snacks and beverage. Immediately there was maximum drop in pH value after test food consumption and up to 30 min maximum of test food got cleared from the oral cavity. CONCLUSION: Due to lack of awareness in child or their parents they don't know the harmful effect of some food so as a dental professional we should guide them about this harmful effect and introduce them to preventive measures, Tooth Friendly diet and oral hygiene practices.
