Saliva is one of the most important factors in regulating oral health, with flow rate and composition changing throughout development and during disease. Numerous chewing habits have been traditionally followed by various cultures and this effects salivary composition. Chewing of fennel seeds (Foeniculum vulgare) is one such practice. This study was done with the objective to record and compare the salivary pH at base line, immediately and five minutes after chewing the seeds.

Materials and methods

Total 22 subjects, aged >18years were requested to chew a known quantity of fennel seeds (1.3grams) for five minutes and salivary pH was recorded using Qualigens Indikrom paper strips.


Highly statistically significant rise in salivary pH was seen immediately after chewing seeds (p=0.003)


Chewing of seeds showed a rise in salivary pH, which can prevent demineralization and have an anti-cariogenic effect.
