[About the Assess Brand] As a pioneer in periodontal disease care research, the company launched Japan's first natural herb-derived periodontal disease pharmaceutical, 'Assess', in 1978. In November 2022, it launched the quasi-drug 'Medicated Assess' series. These products feature formulations focused on sterilization, gum care, and plaque removal for the prevention of gingivitis and pyorrhea. This evolution has transformed 'Assess' into the 'Ideal Oral Self-Care Brand' capable of addressing gingivitis and pyorrhea from 'prevention' to 'improvement'.
