Accuracy of teledentistry versus clinical oral examination for aged-care home residents: A pilot study.

Objectives: The aim of this pilot study is to assess the feasibility of using the mobile photographic method (m-health) of teledentistry for oral screening and triaging of older patients living in aged care homes.

Methods: The study took place in 2023 in four aged care facilities in Egypt. Three trained dentists performed clinical oral examinations of the participants and filled in the World Health Organization (WHO) oral health assessment form. Afterwards, five intraoral photographs were taken for each participant and independently examined by three calibrated dentists for caries detection and decision on intervention urgency for proper dental referral. Agreement between the testing modalities was analyzed using Cohen's kappa coefficient, and the significance level was set at p < 0.05 within all tests.

Results: The results indicated that teledentistry had higher specificity than sensitivity in caries detection compared to clinical examination. The level of agreement between the teledentistry examination and the clinical oral examination for caries assessment ranged from (k = 0.36) to (k = 0.58) showing fair to moderate agreement. Also, all teledentistry examiners showed almost perfect statistically significant intra-rater and inter-rater agreement for caries detection (K ≥ 0.82, p < 0.001). Moreover, intervention urgency scoring showed moderate to substantial agreement between the testing modalities with kappa values ranging from (k = 0.48) to (k = 0.65).

Conclusions: The mobile photographic method of teledentistry offers a feasible model that helps in oral examination and triaging dental treatment of older patients living in aged care facilities. However, larger studies with proper sample size are required which will allow better generalizability of the results.
