Oral radiography is considered an important procedure in dental care. Lack of knowledge about oral radiography procedures can cause anxiety and fear, especially in intellectually disabled children. These children require repetitive and engaging educational approaches. Educational videos are considered an effective way to enhance their understanding. This research aimed to determine the effect of the number of educational video presentations on the knowledge of oral radiography among intellectually disabled students at state special schools in Yogyakarta City.
This study is quantitative research that applied design one group pretest-posttest. Participants of the study consisted of 60 students from a state special school for junior high school in Yogyakarta city, who were selected using a total sampling method. The respondents were divided into three groups with different viewing frequencies: one, two, and three times, with a 24-hour interval between viewings. The instrument used was a closed-ended questionnaire with a Guttman scale. Respondents filled out the same questionnaire twice, namely before and after being provided education through video. The data obtained from the research was tested for normality using the Shapiro-Wilk test. The test results indicated that the data was not normally distributed, so nonparametric statistical tests were used, namely the Wilcoxon test and the Kruskal-Wallis test, with a confidence level of 95% (a=0.05).
The Wilcoxon test results showed a significant value (p<0>0.05). These results indicate that educational videos were effective in increasing the knowledge of intellectually disabled children about dental radiographic examinations, although the number of video presentations did not have a significant effect.
