Objectives

Narrative objectives1

In this study, we aim to evaluate oral diseases such as periodontal disease and dental caries using a gastrointestinal endoscopy system, and to investigate the usefulness of this approach as a means of early identification of patients who require dental intervention. Furthermore, we aim to develop an AI-based system for the automatic assessment of oral health status. As a further objective, since oral health conditions are known risk factors for head and neck, esophageal, and gastric cancers, we will also examine whether the oral findings obtained from gastrointestinal endoscopy can be utilized for risk stratification of these gastrointestinal cancers.

Assessment

Primary outcomes

Diagnostic concordance between oral assessments based on intraoral images (white-light, NBI, and TXI modes) captured by a gastrointestinal endoscopy system and those obtained through direct clinical examinations by dentists

Key secondary outcomes

1. Diagnostic performance of AI-based oral disease detection using endoscopic images

2. Association between oral findings and gastrointestinal or head and neck cancers

An AI-based model for the automatic assessment of oral health status will be developed using intraoral endoscopic images. Although a strict statistical calculation of sample size is not required for AI model development, we aim to construct a highly accurate model by enrolling approximately 500 participants, recruiting as many eligible subjects as possible during the study period. After model construction, an additional 100 participants will be prospectively recruited to perform validation of the AI model using a prospective cohort.

Many patients attending our department undergo annual follow-up esophagogastroduodenoscopy (EGD) for various reasons. For participants registered in this study via the Department of Gastroenterology, routine EGD follow-up will be continued as part of their standard medical care, and the occurrence of gastrointestinal diseases will be prospectively monitored. The relationship between the baseline intraoral findings at registration and the subsequent occurrence of gastrointestinal diseases will be analyzed.
