Use of smartphone video calls in the diagnosis of oral lesions: Teleconsultations between a specialist and patients assisted by a general dentist.

BACKGROUND

Teleassistance in dentistry enables the support of dentists in areas without access to specialists. The aim of this study was to assess the feasibility and accuracy of synchronous teleconsultation in oral medicine.

METHODS

Patients referred for specialized care owing to oral lesions were evaluated in person by a general dentist who obtained photographs of the lesions with a smartphone. The images were sent via a mobile application to an oral medicine specialist, with whom a video call was initiated on the same instant messaging application. After interviewing the patient, the specialist formulated a diagnostic hypothesis and suggestions for case management. Then a second specialist, blinded to the first evaluation, assessed the oral lesion in person and defined a diagnosis, which was considered as the reference standard. Diagnoses from the remote and the face-to-face consultations were compared in percentage levels of agreement and κ coefficient.

RESULTS

Thirty-three patients, 25 through 83 years old, had 41 oral lesions. The average teleconsultation length was approximately 10 minutes. In 92.7% of the cases, there was concordance between the telediagnosis and the reference standard (κ = 0.922).

CONCLUSIONS

Synchronous teleconsultation can provide reliable remote diagnosis through the support to primary care health care professionals in management of oral lesions.

PRACTICAL IMPLICATIONS

Earlier diagnosis of malignancies, improvement of access for unassisted populations, and reduction of unnecessary referrals are possible practical implications of remote support of a specialist in the management and diagnosis of oral lesions.
