Effectiveness of educational poster on knowledge of emergency management of dental trauma--part 2: cluster randomised controlled trial for secondary school students.

ABSTRACT: OBJECTIVE:To investigate the effectiveness of educational poster on improving secondary school students' knowledge of emergency management of dental trauma. METHODS:A cluster randomised controlled trial was conducted. 16 schools with total 671 secondary students who can read Chinese or English were randomised into intervention (poster, 8 schools, 364 students) and control groups (8 schools, 305 students) at the school level. Baseline knowledge of dental trauma was obtained by a questionnaire. Poster containing information of dental trauma management was displayed in a classroom for 2 weeks in each school in the intervention group whereas in the control group there was no display of such posters. Students of both groups completed the same questionnaire after 2 weeks. RESULTS:Two-week display of posters improved the knowledge score by 1.25 (p-value = 0.0407) on average. CONCLUSION:Educational poster on dental trauma management significantly improved the level of knowledge of secondary school students in Hong Kong.

Project description:BACKGROUND:The present study evaluated the effect of two educational interventions on the knowledge and self-reported practice of primary school teachers regarding emergency management of traumatic dental injuries (TDIs). METHODS:All primary school teachers (n = 664) of Arak, Iran were asked to participate in the study. Based on geographic regions, all participants were enrolled in two groups: educational leaflet and oral presentation. At baseline, teachers in both groups were asked to complete an anonymous self-administrated questionnaire consisting of demographics, eight questions on knowledge, and four paper cases on self-reported practice about TDIs. After collecting the questionnaires, interventions, including an oral presentation and an educational leaflet whose contents were prepared based on the most recent scientific evidence, were implemented. One and six months after the interventions, the questionnaire was completed by the teachers again. Repeated measures ANOVA and a linear regression model were used for statistical analysis. RESULTS:Two hundred and ninety-two teachers participated in all stages of the study (response rate = 64.5%). In one-month follow-up, in both groups, the mean score of knowledge was significantly higher compared to baseline and six-month scores (P < 0.001 and P < 0.001, respectively). Moreover, in six-month follow-up, the mean score of knowledge was higher compared to baseline (P < 0.001) in both intervention groups. No statistically significant difference existed in the mean score of knowledge in three evaluations between two groups (P < 0.05). In one-month follow-up, the mean score of self-reported practice was significantly higher compared to baseline and six-month scores in both interventional groups (P < 0.001 and P < 0.001, respectively). There was no significant difference in the mean score of self-reported practice between the one-month and six-month follow-up (P = 0.53). There was no statistical significant difference in the mean score of self-reported practice in three evaluation phases between two groups (P < 0.05). No significant relationship was observed between the difference in knowledge and self-reported practice scores and demographic factors. CONCLUSIONS:Both educational interventions regarding emergency management of TDIs-educational leaflet and oral presentation- were effective in increasing knowledge and self-reported practice of teachers in the short-term follow-up. In long-term evaluation, educational leaflet resulted in more positive changes in teachers' knowledge compared to their self-reported practice.

Project description:BackgroundThe prognosis of replantation of an avulsed tooth is affected by the first aid management in the first 15 min after traumatic incident. Knowledge of the optimal management is crucial to successful replantation. The objective of this study was to investigate the effectiveness of educational intervention using the Arabic version of the "save your tooth" poster designed by the International Association of Dental Traumatology IADT, in improving the knowledge of schoolchildren about first aid management of avulsion of permanent teeth.MethodsAn interventional educational study was undertaken. A total of 550 schoolchildren aged 9-12 years participated in this study. Thirteen public primary schools in Damascus city were selected. A questionnaire was developed to measure the knowledge of schoolchildren about avulsion of permanent teeth. The translated IADT education poster about avulsion management was adopted.The content of this poster was explained to the children. Two months later, the subjects were re-evaluated using the same questionnaire. Paired sample t-test was used to test the differences existed between the two assessments.ResultA total of 537 schoolchildren completed the questionnaires in which (n?=?305) 57% were females and (n?=?232) 43% were males. The findings demonstrated significant improvement in the participants' responses after interventional education (P?<?0.05). The mean score of knowledge increased significantly from 3.71 at the baseline to 4.03 after the intervention (P?<?0.003).ConclusionThe findings of the present study showed that the level of knowledge of Syrian schoolchildren regarding first-aid management of avulsion of permanent teeth was limited at the baseline. The follow-up results showed that the educational intervention based on the "save your tooth" poster was significantly effective in improving the knowledge of schoolchildren. Further interventions to educate all Syrian schoolchildren about avulsion could be of great value to prevent its negative aesthetic, functional, psychological, economic impacts.

Project description:IntroductionAwareness about dental implants is increasing among dental patients, which demands a higher level of competence for dental students. So, the objective of this study was to assess the knowledge and perception of undergraduate dental students about dental implants.Materials and methodsThis cross-sectional questionnaire-based survey was conducted after taking ethical clearance and approval from the Institutional Review Committee of B.P. Koirala Institute of Health Sciences and informed consent from each dental college of Nepal. The sample included all those students who were present at the time of survey. Data collection were carried out during the academic schedules of the colleges, supervised, and monitored by the investigators themselves. Collected data were coded, entered in Microsoft excel 2013 and descriptive analysis was carried out.ResultsA majority of the total (54.6%) and 59.2% of 5th year respondents perceived to be moderately well-informed about dental implants. The main advantage of dental implants was thought to be longevity by 53.1% of total and 48.4% of 5th year students; only 27.6% of the total and 42.2% of 5th year students said the main advantage of dental implants is they are more conservative than other tooth-replacement modalities. Highest percentage of the total respondents (31.9%) said most important factor for implant success to be implant type and material, whereas 59.8% of 5th year students said case selection. Those who felt dental implants require additional oral hygiene maintenance and care by the patient and dentist were 58.4% of total and 75.1% of 5th year students. Over two-thirds (67.5%) of total thought that economic feasibility will limit use of dental implants in Nepal. The difficulty encountered to place implants was perceived to be average by 56.8% of total and 58.1% of 5th year. There were differences in the perception and knowledge at different academic levels, but not as expected.ConclusionsIt could not be concluded that knowledge about dental implants increased with increase in academic level. Even at the late-clinical year a majority of students gave unsatisfactory responses.
