MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541122645 A) filed by Chettinad Academy Of Research And Education; and Chettinad Dental College And Research Institute, Chengalpattu, Tamil Nadu, on Dec. 5, 2025, for 'oral health diagnostic device for real-time detection of salivary biomarkers and dental caries risk assessment.'
Inventor(s) include Shreya S; Vinusha S; Dr Madhuvathani R; and Shruthi M.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a portable oral diagnostic device (100) and method (200) configured for real-time, non-invasive detection of salivary biomarkers to assess dental caries risk. The device (100) comprises a pen-shaped housing (102) enclosing a microcontroller (122), power source (124), and optical sensor interface (118), coupled with a detachable, single-use nib assembly (108) containing a microfluidic channel (112) that directs saliva by capillary action toward a pH indicator region (114) and a biosensor chamber (116). The pH indicator region (114) employs a colorimetric dye, while the biosensor chamber (116) includes an enzyme substrate layer (120) reactive to Streptococcus mutans. The optical sensor interface (118) detects biochemical responses, and the microcontroller (122) computes a composite caries-risk index displayed via a LED indicator (106). The device (100) provides dual-parameter oral-health analysis, enabling instant, hygienic, and laboratory-free caries risk assessment at the point of care."
