The Effect of Brushing With Fluoride Toothpaste on Dental Plague Control for Elementary School Students

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the effect of correct tooth cleaning and use of fluoride toothpaste after school lunch and before going to bed on primary school children's plaque reduction and tooth cleaning skills.

Detailed Description
-----------------
Taking the school as a unit, the participants are children in grades three to six of elementary schools under the jurisdiction of Chiayi County, with a total expected sample size of 400 people. Through class teaching, the Shelley method of brushing teeth is taught, and flossing instruction is added to senior grades to improve students' teeth cleaning skills. They also use fluoride toothpaste with a concentration of more than 1000PPM to clean teeth after lunch at school and before going home to go to bed. School children were tested for plaque before and after using fluoride toothpaste, collected plaque control index, filled out a self-administered tooth cleaning skills and self-efficacy questionnaire, and tracked changes in the six weeks after use. Professional dentists and researchers will go to school to conduct dental plaque testing and fill out the first questionnaire for students. They will also use fluoride toothpaste after lunch at school and before going home to go to bed. Together with correct tooth cleaning methods, at 6 weeks Afterwards, the dental plaque test will be carried out again and the second questionnaire will be filled out. Each filling in of the questionnaire will take about ten minutes.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Experiment group<br>In the experimental group, students from grades three to six in four primary schools in Chiayi County participated. Participating school children are taught the correct method of brushing their teeth, and flossing is also taught in the upper grades. The experimental group used toothpaste containing 1,450 ppm fluoride and asked students to use it at least twice a day, one of which was to clean their teeth before bed. During the pre-test and 4-week post-test, the plaque control index (Plaque Control Record; PCR) was checked and a self-administered questionnaire was filled out. | Other: 1450ppm Fluoride toothpaste<br>* 1450ppm Fluoride toothpaste<br>|
| Active Comparator: Control group<br>In the control group, students from grades three to six in four primary schools in Chiayi County participated. All participating children receive instruction on proper tooth brushing techniques, with flossing included in higher grades. Schoolchildren in the control group were given toothpaste containing 1,000 ppm fluoride and were asked to use it at least twice a day, including once to clean their teeth before bed. During the pre-test and 4-week post-test, the plaque control index (Plaque Control Record; PCR) was checked and a self-administered questionnaire was filled out. | Other: 1000Pppm Fluoride toothpaste<br>* 1000Pppm Fluoride toothpaste<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Plaque Control Record (PCR) | The Plaque Control Record is a very simple percentage or score of the total amount of bacteria present in your mouth. A tooth has 6 surfaces at the gum line being; the lingual side (distal, middle, mesial) and buccal side (distal, middle, mesial). For each patient, PCR will measured each teeth. | Change from Baseline PCR at 6-week after intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Teeth cleaning skill | Teeth cleaning skill is a questionnaire scale. Total of 5 items ex. What method do I usually use to brush my teeth? | Change from Baseline at 6-week after intervention | 
| Self-efficacy | Self-efficacy is a questionnaire scale. Total of 2 items ex.I am confident that I can brush my teeth clean | Change from Baseline at 6-week after intervention |
