This study will be carried out to evaluate and compare the effect of propolis extract mouthwash and pomegranate (botanical name: Punica granatum) extract mouthwash on taste alteration, salivary pH and antibacterial activity against streptococcus mutans in high caries risk patients. Thats by taking unstimulated saliva samples at the morning before using the mouthwash, then taking another one after using the mouthwash and finally after 7 days, to make a bacterial culture and measure the salivary pH by a digital pH meter and evaluate taste changes by a questionnaire.
