The role of oxidative stress in the pathophysiology of various diseases has already been established. In a recent study, researchers have found that probiotics effectively increase antioxidant levels thus minimizing cellular damage. It was published in the Journal of Otolaryngology-ENT Research.
The present study tried to unveil the antioxidant property of probiotics in saliva along with its effect on salivary pH and buffering capacity.
Unstimulated saliva from 10 individuals was analyzed for total antioxidant level, pH, and buffering capacity using a spectrophotometer, pH paper, and buffering strips respectively, before and after probiotic intake for 2 weeks.
Probiotic intake led to an increase in total salivary antioxidant level with no significant changes in pH and buffering capacity. Results obtained were statistically analyzed using a “paired t-test”.
Probiotics are effective in increasing antioxidant level thereby minimizing cellular damage and hence can be used for the prevention of several diseases. Also, an increase in antioxidant level can be easily assessed in saliva, thus, saliva can be used as a routine diagnostic tool.
