Objectives

Narrative objectives1

In this study, we will target periodontal patients aged 65 and over, collecting saliva and blood samples from patients with dementia, patients with mild cognitive impairment (MCI), and healthy individuals as a control group. Using next-generation sequencing for comprehensive analysis, we aim to identify specific bacteria that change in correlation with cognitive function. By combining this with AI, we will conduct more accurate microbiota analysis than conventional methods, aiming to develop preventive measures, early diagnosis, and fundamental treatments for dementia.

Research Procedure:
1. The periodontology department's attending physician will confirm that the patient meets the inclusion criteria and does not violate the exclusion criteria. Afterward, (1) written consent to participate in this study will be obtained based on the patient's free will. (2) The principal investigator (Mizutani) will record the necessary information in the subject identification code list to correspond with the study subjects with their identification codes.
2. After obtaining consent, baseline data collection will involve the collection of samples and information for the following items.
3. Upon completion of basic periodontal treatment, the subjects will undergo saliva collection at rest, blood sampling, and an intraoral examination as part of the following evaluation items.

4. Based on the information obtained in step 2, a cross-sectional analysis will be conducted at Juntendo University using multivariate analysis to explore oral factors that affect systemic conditions. Furthermore, based on the information obtained in steps 2, 3, and 4, a parametric or non-parametric paired test will be performed to compare each parameter before and after dialysis initiation. If any changes are observed, factors influencing these changes will be explored.
