PERBEDAAN pH SALIVA SEBELUM DAN SESUDAH MENGUNYAH BUAH PISANG BARANGAN (MUSA ACUMINATA COLLA) PADA SISWA KELAS VIII SMPN 2 KARANG INTAN KABUPATEN BANJAR

Abstract

Saliva is a complex oral fluid that is a combination of various fluids and
components that are excreted into the mouth. Barangan banana (Musa Acuminata
Colla) is a fruit with fermented carbohydrates that can increase acid production by
bacteria in the oral cavity so that the oral cavity becomes acidic. This situation causes
demineralization of the tooth surface so that the caries formation process can occur.
The purpose of this study was to determine differences in salivary pH before and
after chewing barangan bananas in class VIII students of SMPN 2 Karang Intan, Banjar
Regency. The subjects of this study were 60 people taken by the Total Sampling
method with the design of one group pretest posttest. Saliva was taken by spitting
method which was done before and after chewing barangan banana.
The results showed that the average before chewing bananas was 6.54 and the
average after chewing bananas was 6.47. The results of statistical analysis by Paired
Sample T-test obtained a mean of 0.075, with p value = 0.004, so that it was smaller
than alpha α = 0.05 or (p = 0.004 <α = 0.05).
The conclusion of this study is that there are differences in salivary pH before
and after chewing barangan bananas (Musa Acuminata Cola). It is recommended to
eat fruits, one of which is a good barangan banana to normalize salivary pH.
