ABSTRACT
A Mouth Wash Is A Chemotherapeutic Agent Used As An Effective Home Care Remedy To Improve Oral Hygiene And Prevent Dental Caries By Targeting The Cariogenic Bacteria. Aim : To Evaluate And Compare The Effect Of Three Mouth Washes Of Natural Aqueous Extracts Of Pomegranate, Green Tea And Rosemary On Salivary PH Changes (pH Meter), Plaque Accumulation ( Sillness And L�e Plaque Index) And Counts Of Salivary Streptococcus Mutans And Lactobaciili.

Materials and Methods: Mouthwashes Were Prepared From Aqueous Extracts Of Pomegranate, Green Tea And Rosemary . 40 Children, Aged From 4-6 Years And 12-15 Years, Were Asked To Use Mouthwashes For 4 Days .The Effect Of Mouthwashes Were Evaluated On PH Of Saliva, Plaque Accumulation Rate And The Count Of Salivary Streptococcus Mutans And Lactobacilli. The Collected Data Were Statistically Analyzed. Results; In Both Age Group, After Using Mouthwash, Green Tea Mouthwash Showed Statistically Significantly Lower Mean Value In Mean Plaque Index Score After Using Mouth Wash. Rosemary Mouthwash In Group A(aged From 4-6y) Showed The Highest Mean PH Score With Non-statistically Significant Difference From Green Tea Subgroup. The Three Herbal Mouthwashes Showed Their Significant Inhibitory Effect On Streptococcus Mutans And Lactobacilli In Both Age Groups. Conclusion: Pomegranate, Green Tea And Rosemary Mouthwashes Could Be An Appropriate And Safe Choice To Decrease Dental Caries In Children.
