Objectives
Narrative objectives1
Oral diseases are mainly bacterial infections. Compared to normal people, people with disabilities have poor oral hygiene and a higher incidence of oral diseases such as dental caries and gingivitis. In addition, even if they have oral diseases, they often cannot complain of pain or difficulty in chewing and are found in an advanced state. In order to prevent these diseases, daily brushing is of utmost importance. However, if a person has a strong refusal behavior due to a disability, assisted brushing can be burdensome for the caregiver, making it difficult to maintain adequate oral hygiene. Therefore, this study was conducted to measure the efficiency of plaque removal and the rate of periodontitis inhibition by continuous use of a sonic toothbrush with high bacterial removal efficiency and a manual toothbrush with high bacterial removal accuracy in assisted brushing of patients with disabilities using the conventional indices PlI and GI and the new index PISA. In addition, the changes in the number of bacteria, genome, and In addition, changes in the number of bacteria and changes in the oral flora by genome analysis will be evaluated. In this study, the effects of assisted brushing with a sonic toothbrush on the gingiva of people with disabilities and its clinical effects will be clarified. In addition, the degree of burden on the caregiver will be verified by questionnaire, and an efficient oral cleaning method with less burden for both the patient and the caregiver supporting the patient will be proposed.

Interventions/Control_1
Forty patients with disabilities who regularly visit our department and who have obtained written consent from their guardians will be included. At the time of the regular checkup, the age, sex, type and degree of disability, background disease, and treatment will be transcribed from the medical record. The dentist in charge will evaluate the PCR, PlI, GI, and PISA scores of the patients 1-5 hours after meals and collect dental plaque. The collected plaque will be counted for bacteria using a calisimeter. In addition, a questionnaire regarding the level of burden associated with assisted brushing will be administered to caregivers. The PCR will be assessed every 8 weeks to measure changes in oral hygiene over time. 32 weeks later, the same assessment will be conducted as before the intervention to evaluate changes over time in each group and to assess differences between groups. After 32 weeks, the same assessment will be performed as before the intervention to evaluate the change over time for each group and to evaluate the difference between the groups.
