Lion Co. introduced its SMT test (salivary multi test) in May 2016. The test strip kit allows the simultaneous measurement of six saliva indicators within 5 minutes: cariogenic bacteria, pH and buffer capacity, leukocytes, proteins and ammonia, as an indicator related to oral cleanliness. After many field tests including 80 employees of Lion in Hirosaki City, it turned out that the test has raised awareness about good oral hygiene and has led to improvement of oral health as judged by dentists evaluation.
