  • Teledentistry accuracy for caries diagnosis: a systematic review of in-vivo studies using extra-oral photography… 2024 All outcomes
    Cross-sectional diagnostic accuracy (index test vs reference standard, in-vivo) · In-vivo: dental clinics/hospitals, schools, and a juvenile detention facility (11 countries) · Overall (studies reporting sensitivity; narrative synthesis)
    Sensitivity Overall 48% to 98.3% across 13 studies; sensitivity is lesion-stage dependent: Kohara reported <40% for initial/moderate caries (75-100% for extensive) and early enamel lesions were less sensitive
    13 studies
    GRADE not reported
