The majority of the burden of periodontal diseases in the population remain undetected. Self-detection and confirmation with simple, non-clinical tests may improve early case detection and access to the needed level of care. A recently conducted study has indicated that self-reported signs and symptoms through questionnaires and gingival bleeding on brushing (GBoB), in particular, are potentially useful approaches to detect gingival inflammation and other signs of periodontal health and disease. A parallel study evaluated the accuracy of the presence of elevated levels of activated matrix metalloproteinase-8 (MMP-8). A strategy combining specific questions, subject demographics, GBoB and aMMP-8 has shown promise for screening and diagnosis of periodontal health and disease. Validation of a diagnostic approach requires assessment in a first population (development group) and confirmation in an independent one.
