Social media patient testimonials in implant dentistry: information or misinformation?
OBJECTIVE
This study aims to assess the educational value of YouTube patient testimonial videos in implant dentistry and qualitatively analyse the themes mentioned.


METHODS
Videos were sampled consecutively on YouTube, using the keywords "dental implant patients' testimonials experience," sorted "by relevance." Patient testimonials on dental implant treatment were examined. Inaudible or non-English videos were excluded. Four calibrated investigators scored the videos for educational content, using a matrix derived from the European Association for Osseointegration information booklet, and demographic details were recorded. Data were analysed qualitatively through inductive thematic analysis.


RESULTS
A total of 202 videos were analysed (48 exclusions). Inter-examiner reliability was fair to moderate for informative statements and poor to substantial for misleading statements. A mean of 1.8 informative statements were made per video, compared with misleading, 0.5. Many topics were rarely mentioned, with 19/30 themes appearing fewer than 5% of videos. Patients often informed that implants could improve aesthetics and function, but were misleading on aspects of pain control. Some statements may heighten expectations or imply permanency of treatment.


CONCLUSIONS
Balanced presentation in YouTube testimonials may be limited by bias of clinician-uploaded content. Greater magnitude and breadth of information would improve educational value. Many important parameters of implant therapy were overlooked, whilst information was often potentially misleading.
