The quality of Web-based orthodontic information: A scoping review

Patients seeking health information on the Internet is commonplace. This scoping review aimed to collate and synthesize the evidence regarding the quality of Web-based orthodontic information.

A systematic search and independent screening process was conducted by 2 independent reviewers across 4 databases. The review was conducted in alignment with the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines.

Of 661 records identified, 30 publications satisfied the inclusion criteria. Reviewed studies included those related to the information contained within Web sites regarding dental and orthodontist practices, orthodontic interventions, appliances and auxiliaries, orthodontic conditions commonly requiring orthodontic therapy, issues related to patient experience, and advice during orthodontic treatment. A total of 5 quality of information (QOI) instruments and 3 readability tools were employed, with the University of Oxford, United Kingdom (DISCERN) instrument and the Flesch Reading Ease Score tool being the most frequently used. Most studies determined that the QOI contained within evaluated Web sites was poor and provided suboptimal information related to treatment risks and Web site reliability. Most studies indicated that the information was more difficult to read than recommended by guidelines.

The QOI of orthodontic information available on Web sites was low to moderate, with the readability of content at a level that was considered challenging for many readers to understand. A recommendation for greater involvement of the dental and orthodontic specialty in Web site development was commonplace. Research is required for the development of validated tools that can determine the accuracy of information in addition to Web site reliability.
