- The modified questionnaire of the Centers for Disease Control and Prevention and the American Academy of Periodontology is useful for self-detecting periodontal diseases, and its integration with demographic/lifestyle variables further improves diagnostic performance.
- The oral rinse activated MMP-8 point-of-care test can identify different severities of periodontitis, and combining it with individual and lifestyle profiles enhances diagnostic performance.
- Self-reported gingival bleeding on brushing is a sign of periodontal diseases, particularly gingival inflammation.
- The haemoglobin levels of saliva/toothpaste slurry could be useful for identifying generalised severe periodontitis.
- Salivary biomarkers of certain adipose metabolism–related and ageing-related proteins as well as inflammatory cytokines may potentially identify patients with severe periodontitis.
