Objectives This study investigated the accuracy and duration of intraoral digital photograph examination (IDPE) for evaluating oral health status and explored the feasibility of remote oral health assessment. Methods Thirty-one healthy college students underwent evaluations of oral health status via clinical examination (CE) combined with panoramic X-ray assessment at baseline, followed by IDPE 1 month later using photos taken at baseline. Methods for evaluation of gingival health included the Modified Gingival Index (MGI) and Plaque Index (PI). Examinations of caries status included the decayed, missing, and filled teeth and surfaces indexes (DMFT and DMFS indexes, respectively). The duration of each evaluation was also recorded. Results There were significant differences in MGI and PI between CE and IDPE. There were no significant differences in DMFT and DMFS indexes between CE and IDPE, and there were positive correlations between CE and IDPE for each of the two indexes (DMFT index: r=0.56; DMFS index: r=0.69). The IDPE duration was shorter than the CE duration. Conclusions The feasibility of caries status assessment via IDPE is promising. Digital oral health evaluation merits further clinical consideration.
