Effect of 5% Aqueous Propolis in Salivary and Dental Plaque pH in Children

Effect of 5% Aqueous Propolis Added to Sugar-Free Chewing Gum in Salivary and Dental Plaque pH in Children (in Vivo Study)

This study aims to investigate the changes in saliva and dental plaque pH after consuming sugar-free chewing gum containing 5% of aqueous propolis in children aged between 8-11 years. The studied sample will be divided into two groups: Group A (Control group) placebo chewing gum, and Group B (Experimental group) aqueous propolis chewing gum. All children will experience both types of chewing gum with an interval of 1 week between the two studied groups.

This study will evaluate saliva and dental plaque pH after consuming 10% sucrose solution and then each child will test each of the two types of gum (aqueous propolis 5% and placebo gum) so that the child himself is the control and tested sample together, according to the following order:

• In the first visit: the pH of saliva and dental plaque will be measured (before giving the sucrose solution, while chewing one of the two types of gum, and after giving the sucrose solution).
• In the second visit: after a week, the pH of saliva and dental plaque will be measured (before giving the sucrose solution, while chewing the other types of gum, and after giving the sucrose solution).)
