Communication of health information is considered a cornerstone for the success of any treatment. This includes patient education that is a relevant component of health care, and continuing education that is critical in professional development.It is the responsibility of healthcare professionals to provide patients with healthcare information in relation to their condition. Nevertheless, this role is changing nowadays with the increasing use of the Internet to seek health care-related information. The considerable penetration and the free accessibility of the Internet boost the patients' desires to be self-informed, at the expense of the face-to-face professional interview. 1-3 Increasing number of consumers are using social media to seek information and support for health-related issues. 4 It has been shown that 59% of US adults have looked online for health information in 2012. 5 This implies Abstract Objectives: To evaluate the quality of the scientific/clinical information in dentistry delivered by videos hosted by a popular video-sharing website. Methods: The gingival recession condition was used as a model and YouTube™ as the video hosting service. A systematic observation of videos containing information on gingival recession was conducted. Videos were analysed to evaluate (i) the scientific reliability and quality of the information using Global Quality Scale (GQS) and DISCREN criteria; and (ii) the understandability of this information using a tailormade custom comprehensiveness index (CI). Results: One hundred and eighty videos were identified. Videos dealing with surgical procedures were not included in the present review. After selection, 41 videos were analysed. The mean GQS was 2.34 on a 0-5 scale, and 25 (61%) videos showed clear aims according to DISCREN criteria. Misleading content was observed in eight videos (19.5%). The scientific sources of information were unclear in 26 (63.4%) videos. All videos failed to give additional references for supplemental information. Only three videos (7%) provided basic information on aetiology, clinical presentations and management of gingival recession. Based on 0-2 CI scores, three, nine and 29 videos had a score of 2, 1 and 0, respectively.
Conclusion:The present model indicates that social media websites aiming to provide health information should be carefully accounted, especially when dealing with dentistry. It also suggests professional involvement to improve the quality of the delivered information.
