Oral Health Clinical Trial
Official title:
The Effect of the Different Number of Topics in Educational Video on Oral Health Status of Preschool Children: Study Protocol for a Cluster Randomized Controlled Trial (RCT)
Purpose: This cluster randomized controlled trials study aims to investigate whether different number of topics delivered through educational video affect the oral health status, knowledge, attitude and practice of preschool children. Hypothesis: The hypothesis of this study is the number of topics covered in educational videos aimed at preschool children will have a direct impact on their oral health status. The specific hypothesis is the educational videos covering wide range of oral health topics will lead to better oral health outcomes in preschool children compared to videos focusing on limited number of topics. The higher number of topics delivered in educational video, the better oral health status, knowledge, attitude, and practice. The alternative hypothesis is the combination of three topics on effective toothbrushing technique, effects of sugary food, and dental caries is effective to led to the most improvement in oral health status, knowledge, attitudes, and practices compared to two or only one topic. Objectives: The objectives of this study were divided into primary and secondary. The primary objective of the study is to assess the effect of different number of topics in educational video versus placebo video on mean difference in plaque score and gingival score among preschool children at baseline and 4 weeks after intervention. The secondary objective is to assess the effect of different number of topics in educational video versus placebo video on mean difference in knowledge, attitude and practice score among preschool children at baseline and 4 weeks after intervention. Participants: The study will involve 124 preschool children aged five to six years old. Methods: Researchers will randomize classes in the school into five clusters using closed enveloped technique. These five clusters will be randomly assigned either into interventional groups or control groups. There are four intervention groups and one control group. Each intervention group will be compared to a control group for mean difference in plaque, gingival and KAP score at baseline and after intervention. Duration: The study is expected to last 6 months (from subjects recruitment to final research report) with regular updates on progress. Location: The study will be conducted at a preschool in Kota Bharu Kelantan.

Primary | Plaque score using Modified Dental Plaque (MPI) | The index will be calculate dental plaque on each tooth surface. The MPI score is obtained by the sum of the plaque score for all teeth, divided by the number of surfaces scored.
Minimum value for the score is 0, while the maximum value is 5. The higher the score value describes the more plaque accumulation on each subject. Therefore, a high plaque score is interpreted as poor oral hygiene status. To give clinical relevance to the index, the index translated into four oral hygiene categories as 0 - 1.25: Excellent, 1.25 - 2.50: Good, 2.50 - 3.75: Fair, 3.75 - 5.00: Poor |
Baseline and 4 weeks after intervention | |
Primary | Gingival Score using Modified Gingivitis Plaque (MGI) | The index will be calculated the extent and the severity of gingival inflammation using four ordinals.
The MGI score is obtained by the sum of the gingival score for all teeth, divided by the number of surfaces scored. The minimum value for the score is 0, while the maximum value is 3. The higher the score value describes the more severe inflammation due to plaque accumulation in subject. Therefore, a high gingival score is interpreted as poor gingival health. To give clinical relevance to the index, the index translated into three gingivitis categories, 0 : No gingivitis, =1.0 : Mild gingivitis, =2.0 : Moderate gingivitis, =3.0 : Severe gingivitis. |
Baseline and 4 weeks after intervention | |
Secondary | Knowledge, Attitude, Practice (KAP) level using KAP score | KAP score generated from the validated questionnaire used in National Oral Health Survey of Preschool Children, Ministry of Health, Malaysia, 2015. Response options are binary in nature, as the question for preschool children is age-appropriate language that preschool children can comprehend with a straightforward and factual answer. This questionnaire will be validated for content and response process. The questionnaire consists of three domains with 18 items. The domains are knowledge (6 items), attitude (6 items) and practice (6 items). Total score of knowledge, attitude and practice (6X3) is 18. Each item will be given with responses 'Yes' and 'No'. Each item is assessed by one correct answer from answer options with total KAP score ranged from 0 to 18. Average score will be translated into percentage. Then, the score translated into three KAP level categories as, <30%: Poor OHKAP, 30% - 60%: Fair OHKAP, > 60% Good OHKAP | Baseline and 4 weeks after intervention |
