Since severe periodontitis occurs globally in 15- 20% of adults ages 35 to 44 globally, the conventional probing procedure is time-consuming and painful for the patient, and comparably specific devices diagnose rather than monitor disease progression, we are proposing a Periodontitis Monitoring Device for dental professionals, which will measure a clinically-relevant biomarker and correlate it to periodontal severity (healthy, moderate, severe, or aggressive periodontitis).
