Abstract
ObjectiveTo investigate the effectiveness of educational posters in improving the knowledge level of primary and secondary school teachers regarding emergency management of dental trauma.MethodsA cluster randomised controlled trial was conducted. 32 schools with a total of 515 teachers were randomised into intervention (poster) and control groups at the school level. Teachers’ baseline levels of knowledge about dental trauma were obtained by using a questionnaire. Posters containing information on dental trauma management were displayed in the school medical room, the common room used by staff, and on a notice board for 2 weeks in each school of the intervention group; in the control group, no posters were displayed. Teachers in both groups completed the questionnaire after 2 weeks.ResultsThe teachers in the intervention schools (where posters were displayed for 2 weeks) showed statistically significant improvement in scores in cases where they had not previously learned about dental emergencies from sources other than first aid training, with an average score increase of 2.6656 (score range of questionnaire, −13 to 9; p-value <0.0001).ConclusionEducational posters on the management of dental trauma can significantly improve the level of knowledge of primary and secondary school teachers in Hong Kong.

Highlights
Emergency management of traumatic dental injuries is of key importance, as the prognosis of traumatized teeth, especially from avulsion, depends on prompt management [1]
Teachers can help to improve the prognosis of these injuries if they know how to manage at the site of injury
Teachers working in primary or secondary schools in Hong Kong who can read Chinese or English were included in this study
Summary
Emergency management of traumatic dental injuries is of key importance, as the prognosis of traumatized teeth, especially from avulsion, depends on prompt management [1]. Teachers can help to improve the prognosis of these injuries if they know how to manage at the site of injury. A literature search of studies on education in traumatic dental injuries took place before the study and was finalized on January 29, 2013 (search terms included ‘‘education*’’ or ‘‘intervention’’ or ‘‘promotion’’ or ‘‘campaign’’ or ‘‘knowledge’’ or ‘‘lecture’’ or ‘‘seminar’’ or ‘‘leaflet’’ or ‘‘pamphlet’’ or ‘‘poster’’) and (‘‘dental trauma’’ or ‘‘traumatic dental injur*’’ or ‘‘dental injur*’’). 13 papers related to education of teachers in the management of traumatic dental injuries were found on PubMed, Ovid, Web of Science, and the Cochrane Central Register of Controlled Trials through this search [12,13,14,15,16,17,18,19,20,21,22,23,24]
