NOTE: This is an unreviewed Preprint

Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note “no longer under consideration” will appear above).

Peer-review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a “Peer-Review Me” button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.

Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).

Final version: If our system detects a final peer-reviewed “version of record” (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.

Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.

Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.

Properly taken photos is a critical factor for the remote diagnosis of dental trauma and thus benefit its prognosis. The quality of the images collected by a cell phone depends on the level of dental knowledge of the person who is taking the photos.


This study was to investigate the efficacy of education in the enhancement of transmitted images for remote diagnosis of dental trauma.


The subjects included 30 laypeople and 30 dentists. They were randomly assigned into 15 subgroups with two in each. Everyone was asked to take photos of anterior teeth of himself/herself and his/her partner’s assumed an accident occurred, by using both iPhone 4s and iPhone 6. Education about how to take a proper photo of anterior teeth for teleconsultation was then performed. Photos were taken again. An assessment was carried out by a dentist base on the quality of photos for diagnosis.


Finally, 965 photos were collected, from which 441 photos were taken by laypeople while 524 photos were taken by dentists. The photos taken after education had significantly higher scores than those taken before education in all items (P<.05). The photos taken by rear camera had significantly higher scores than that taken by the front camera by him/herself (P<.02). iPhone 6 did not have overwhelming advantages. The photos taken by dentists had significantly higher scores than that taken by laypeople in most of the evaluated items.


Education might be useful in taking qualified photos for teleconsultation in both laypeople and dentists. The type of cellphone does not significantly affect the qualities of photos.
