Comparison of 5 Buffering Agents on Changes in Salivary pH in Individuals Previously Exposed to a Test Fruit Juice

Summary

The diurnal variation in the flow of saliva and hence the composition of saliva is an established fact. Consumption of most types of acidic and sweetened foods and beverages are known to reduce the pH of saliva and some of them even 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 selected commercially available test fruit-juice drink on the salivary pH and assess the buffering capacity of the saliva with or without various intervention measures following the exposure to the test fruit-juice drink at different time intervals.

Conditions

• Saliva Altered
• Oral Hygiene
• pH
• Tooth Structure; Disorder

Interventions

OTHER

Group 1: no intervention

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 mixed fruit juice without any intervention.

OTHER

Group 2: tap water gargle

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.

DRUG

Group 3: 0.2% Chlorhexidine

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.

OTHER

Group 4: Fluoridated tooth paste

The subject will Brush with fluoridated toothpaste-(Colgate Total®, Colgate-Palmolive Company, Mumbai, India) for 2 minutes using soft brush. 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 using tooth paste as an intervention.

OTHER

Group 5: Polyol containing gum

The subject will chew polyol containing gum (Orbit®, WrigleyCompany) for 5 minutes 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 chewing as an intervention.

OTHER

Group 6: 1% sodium bicarbonate solution

The subject will use 10 ml freshly prepared 1% sodium bicarbonate w/v solution 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.
