USA: Researchers have discovered that including certain probiotics in the diet can help eliminate bad breath otherwise known as, Halitosis.
Previous researches have proved that several factors contribute to Halitosis, poor dental hygiene being one the most important ones. Halitosis is mostly caused as a result of sulphuric compounds buildup in the mouth, these compounds are deposited by anaerobic bacteria that feed on food debris.
This new meta-analysis probes into the effect probiotics can have on bad breath-producing compounds and bacteria. The study is published in BMJ Open.
The recommended probiotics observed in this study are Lactobacillus salivarius, Lactobacillus reuteri, Streptococcus salivarius, and Weissella cibaria, all of which may benefit gut health. They are found in fermented foods.
To conduct the study seven randomized controlled trials (RTCs) were analysed.
The total number of patients in all trials was 278 whereas 23 to 68 individuals participated in each trial. Ahed between 19 to 70.
Halitosis was measured both subjectively and objectively for up to 12 weeks.
Researchers detected halitosis levels by allowing them to close their mouths for 1 minute before exhaling into an evaluator’s nose from a distance 10 centimeters. Organoleptic scores (OLPs), were recorded based to the impressions of smell and taste.
Sulphuric compounds, or VSCs, were measured using a halimeter, an instrument that detects and measures the presence of gases.
The results of the study showed a significant decrease in halitosis according to both measurement methods they used.
Compared to control groups, organoleptic scores decreased by 58%, while VSC scores dropped by 26% as a result of the probiotics incorporated by the participants at the end of the trial period
