Abstract
|
Before
In this research, we study causal impacts of interventions which will provide information on oral health, especially how to prevent periodontal disease. By conducting online surveys and providing information on prevention and treatment of periodontal disease to randomly selected individuals, we aim to study whether and how people change their perception/behavior on oral health.

In this research, we study causal impacts of interventions which provide information on oral health, especially how to prevent periodontal disease. By conducting online surveys and providing information on prevention and treatment of periodontal disease to randomly selected individuals, we aim to study whether and how people change their perception/behavior on oral health.The third survey asks respondents the same set of questions plus new questions to see whether the intervention persist or not.

Experimental Design (Public)
|
Before
We conduct a survey asking for their perception and behavior about oral health. The survey includes quiz on periodontal disease and its prevention. Subjects in treatment group will receive information on quiz answers and the number of correct answers along with the baseline survey. Subjects in control group will be asked to answer the baseline survey, which does not include quiz answers nor the number of correct answers.

After
We conduct a survey asking for their perception and behavior about oral health. The survey includes quiz on periodontal disease and its prevention. Subjects in treatment group receive information on quiz answers and the total number of correct answers along with the baseline survey. Subjects in control group are asked to answer the baseline survey, which does not include quiz answers nor the total number of correct answers.
