Design outcomes

Primary

Measure	Time frame
Research on changes in oral flora uses saliva collected at the first time, one month, and three months after the oral environment measurement. Analyze the bacterial and fungal flora in saliva (oral flora) and find out what kinds of bacteria are common in saliva. We will outsource some of the analysis to Kochi University's Genetic Experiment Facility.	—

Secondary

Measure	Time frame
First, we will collect saliva and measure the oral environment. Afterwards, the examinee will be asked to watch a recording of oral care education (including practical brushing instruction) and perform brushing for 3 months. We will also ask the examinee to keep a record of their oral care implementation status (attached) for three months. Saliva samples will be collected again after 1 and 3 months to measure the oral environment. The principal investigator, who is a dentist, will examine the examinee 's saliva using an oral environment measuring device. To collect saliva, have the examinee put saline in their mouth, rinse for 10 seconds, and then spit into a spitz (or paper cup). After rinsing for 10 seconds, Then, collect the saline rinsed for 10 seconds with a dropper and measure it using an oral environment measuring device.	—
