Condition: Periodontitis · Biomarker in Early Diagnosis · Saliva · Sponsor: Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University
Periodontitis is a major public health issue in China: it is responsible for loss of masticatory function in 60 million older adults, and 400-500 million adults are on the same disease trajectory. In addition, gingivitis and early-stage periodontitis are highly prevalent in all age groups. The Lancet 2021 burden of disease study provides worrying projections for China's oral health, with a 47.8% increase in advanced-stage periodontitis and a 217% increase in edentulism by the year 2050. The numbers are not manageable by the Chinese health system unless a series of coordinated actions are implemented: i) health education promoting oral hygiene in school and the workplace; ii) effective AI-based self-detection strategies and accurate identification of high-risk subjects; iii) efficient treatment modalities; and iv) reorganization of the health system. We have developed, patented, and validated a self-detection AI-based screening test for the general population through an app. It is based on a few validated questions and the performance of a lateral flow immunoassay to detect activated matrix metalloproteinase 8 (aMMP8). The algorithm enables accurate self-detection of severe periodontitis. The system, however, cannot identify subjects without clinically evident periodontitis (subjects who present with superficial inflammation consistent with gingivitis and incipient periodontitis) who will develop the disease, which, therefore, should be the target of early interventions.
