About this study
Official title: Effectiveness of Educational Poster to Primary and Secondary Teachers Regarding Emergency Management of Dental Trauma - A Cluster Randomised Controlled Trial
The poster is effective in improving the level of knowledge regarding dental trauma of primary and secondary schools teachers in Hong Kong.
A cluster randomized controlled trial was conducted in mid May 2011,to test the level of knowledge regarding dental trauma with two groups, the intervention group with posters and control group without posters. A questionnaire is used to test the level of knowledge.
Read the detailed description
A cluster randomized controlled trial was conducted in mid May 2011, Hong Kong where no educational campaign regarding dental trauma targeting on primary and secondary school teachers was implemented before.
Lists of Primary and secondary schools were requested from the Education Bereau. Schools were invited to join the study from 1.3.2011 and then randomized to the intervention group and the control group in the unit of school using computer generated numbers.
All teachers filled in the first questionnaire and send it back to the investigator in 1 week. 3 copies of the same educational poster were given to the intervention schools, these schools were requested to display them in 1. the medical room 2. staff common room and 3 anywhere that information was usually placed for the teachers. No poster was given to the control group. After 2 weeks, the posters were removed by the teacher in charge. The same questionnaire was filled in by all the teachers in both groups and sent back in 1 week. The data were processed to show whether the poster was effective to improve the knowledge of the teachers. The study was complied with Declaration of Helsinki and ICH GCP guidelines
