Purpose: Recent studies have found visual and tactile examination to be superior in caries diagnosis than conventional intra-oral radiography (mainly bitewings and periapicals). Extra-oral bitewing radiograph (EBW) is a patient-friendly, non-aerosol-generating technique. To date, the sole studies on EBWs have been in-vitro, and though encouraging, they indicate a higher likelihood of false positives. This is the first study in which findings on EBWs was compared with the clinical visual-tactile examination. The aim of our study is to evaluate the role of EBWs in caries diagnosis- by comparing EBW to clinical data retrospectively and comparing caries noted on EBWs to conventional intra-oral bitewing radiographs (IBW) Methods: This retrospective study was done by reviewing records of pediatric patients attending Ridge Meadows Children’s Dentistry, Maple Ridge from 01 Jan 2017 to 21 Jan 2022. To elicit how EBW compares to clinical findings, 193 patient charts were reviewed to compare the treatment planned to the treatment executed. To compare the depth and accuracy of caries diagnosis between 2 imaging modalities (IBW and EBW), 104 preoperative IBW and EBW radiographs were analyzed by 2 independent examiners using International Caries Classification and Management System (ICCMS) classification. Kapa agreement was done for statistical analysis. Results: EBW was found to be comparable to clinical findings of caries with high positive predictive value (PPV) of 98% and negative predictive value (NPV) of 78%. The data comparing caries on IBW and EBW was assessed quadrant wise and moderate agreement was found for contacts in the lower arch and a weak agreement was found for the upper quadrants. Conclusion: Our results suggest that EBWs are a useful diagnostic tool for proximal caries in children with high caries risk.
