Data analysis used T-Test statistic at CI:95%. Collecting data by measuring saliva pH between gargling with betel leaf stew and sago leaf stew, both before and after treatments.
The research design is quasi-experiment, conducted on 26 elementary students of Banda Aceh as many as 60 students and divided into 3 groups.
The objective of the study was to measure the effectiveness of gargling with the decoction of betel leaf and the decoction of saga leaves to the degree of acidity of saliva in the students. By 2013, nationwide primary school children who experience dental and mouth problems of 25,9%, the picture shows that dental and oral health status is still problematic. Changes are measured by a pH of 0-14 to saliva, alkaline, and neutrality.
