The objective of this study was to compare the effects of Jaftex and Persica mouthwashes on salivary pH and buffer capacity. This clinical, double-blind, on two groups of 20 people. The salivary pH and buffer capacity of all samples were determined. Persica mouthwash was given to group A and Jaftex mouthwash was given to group B. At minutes 5, 10, 15, 20, and 30, after using mouthwashes, the saliva samples were re-collected and the pH and degree of buffer capacity of the samples were measured. After 72 hours of washout period for both groups, Jaftex was given to group A and Persica was given to group B and the saliva samples were re-collected in the mentioned minutes and the pH and the degree of buffer capacity were determined. The results were analyzed by repeated measures test. Significant level was considered The mean pH of saliva in the times before and after 5, 10, 15, 20 and 30 minutes was 7.05, 6.78, 6.67, 6.74, 6.65, and 6.82, respectively, Jaftex mouthwash was 6.99, 7.30, 6.69, 6.66, 6.67, and 6.99, respectively, and pH difference between the first 5 minutes and before the use of Persica and Jaftex mouthwashes was significant (P <0.05). The results of this study did not show an increase in salivary buffer capacity in two groups. The use of Jaftex as an herbal mouthwash is effective in preventing tooth decay and it is recommended to the people with high risk of decay.
