About this study
Official title: Evaluation of Efficacy of Antibacterial Activity of Licorice, Clove, and Chlorohexidine Mouthwashes on Salivary Streptococcus Mutans in a Group of Egyptian Children: Randomized Controlled Trial.
A randomized controlled trial that compares the antibacterial effectiveness of three mouthwashes-licorice, clove, and chlorhexidine-in Egyptian children aged 7-12 years.
The main focus is Streptococcus mutans, one of the main bacteria associated with dental caries. The saliva samples will be collected from the children and the amount of S. mutans will be measured before and after using the assigned mouthwash.
Read more
The children will be randomly divided into groups, with each group receiving one of the three mouthwashes. The bacterial counts will then be compared to determine which mouthwash is most effective at reducing salivary S. mutans.
The research question is whether natural mouthwashes made from licorice or clove reduce the bacteria that cause cavities as effectively as chlorhexidine in children?
The study could help determine whether licorice and clove are effective natural alternatives or adjuncts to chlorhexidine, particularly considering that chlorhexidine can have undesirable effects with prolonged use.
Overall aim: Compare and evaluate the antibacterial efficacy of the three mouthwashes

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Mouth washOther
The interventions will consist of three different mouthwashes: licorice mouthwash, clove mouthwash, and 0.2% chlorhexidine mouthwash. Each participant will use the mouthwash assigned to their study group according to the standardized study protocol. The herbal mouthwashes will be prepared using standardized licorice and clove extracts at predetermined concentrations, while the chlorhexidine group will receive 0.2% chlorhexidine mouthwash as the positive control. All mouthwashes will be provided in identical, appropriately labeled containers to maintain blinding where applicable. The interventions will be distinguished by their active ingredient and concentration, while the method, frequency, duration of use, and volume administered will be standardized across all groups.
