Brief Summary
The diurnal variation in the flow of saliva and hence the composition of saliva is an established fact. Consumption of acidic and sweetened food and beverage is known to reduce the salivary pH and some of them reduce it to critical pH levels and result in structural damage to the hard tissues of the tooth. The purpose of this study is to ascertain the effect of the select commercially available test carbonated drink containing sugar on the salivary pH and assess the buffering capacity of the saliva with or without various intervention measures following the exposure to the test carbonated drink at different time intervals.

Outcome Measures
Primary Outcomes (1)
pH of Saliva at baseline
All subjects in all groups collects the unstimulated saliva in a sterile glass dish for the measurement of baseline pH of the saliva. The subject will give the saliva sample just before being exposed to the test carbonated drink by swishing 100ml of CocaCola in mouth for 2minutes and then drinking it The outcome accessor is blinded to origin of sample (from which group).

Study Arms (6)
Group 1: no intervention
ACTIVE COMPARATORThe subject collects the unstimulated saliva in a sterile glass dish for the measurement of baseline pH of the saliva.The subject is then given 100 ml of test carbonated drink, Coco cola ® to drink. The subject will sip, swish and swallow the drink within 2 minutes. Unstimulated saliva samples are collected from the subject to measure the pH of saliva after 5, 15, 30, 45 and 60 minutes of consumption of the test carbonated drink.
Group 2: tap water gargle
EXPERIMENTALThe subject collects the unstimulated saliva in a sterile glass dish for the measurement of baseline pH of the saliva.The subject is then given 100 ml of test carbonated drink, Coco cola ® to drink. The subject will sip, swish and swallow the drink within 2 minutes. Unstimulated saliva samples are collected from the subject to measure and record the pH of saliva after 5 and 15 minutes of consumption of the test carbonated drink. The subject will use 10 ml of tap water as mouth rinse to swish for 60 seconds and spit. Unstimulated saliva samples are collected from the subject to measure and record the pH of saliva at 15, 30 and 45 minutes after the subject completes the gargle as an intervention
Group 3: 0.2% chlorhexidine
EXPERIMENTALThe subject collects the unstimulated saliva in a sterile glass dish for the measurement of baseline pH of the saliva.The subject is then given 100 ml of test carbonated drink, Coco cola ® to drink. The subject will sip, swish and swallow the drink within 2 minutes. Unstimulated saliva samples are collected from the subject to measure and record the pH of saliva after 5 and 15 minutes of consumption of the test carbonated drink. The subject will use 10 ml of 0.2% Chlorhexidine mouth rinse (Rexidine®, Indoco Remidies Ltd, Mumbai, India) to swish for 60 seconds and spit. Unstimulated saliva samples are collected from the subject to measure and record the pH of saliva at 15, 30 and 45 minutes after the subject completes the gargle as an intervention.
