In recent years, “real-world data” collected from actual events, occurrences, or observations in the fields of healthcare and caregiving has been increasingly utilized in clinical research. This paper presents findings from a large cohort study on the association among partially edentulous arch, tooth loss, and all-cause mortality. This study is based on approximately 250,000 data points from dental checkups of older adults conducted in Osaka Prefecture from 2017 to 2021, as well as medical claim data from the Kokuho Database. The discussion focuses on the impact of partially edentulous arch on the subsequent loss of remaining teeth and systemic health from the viewpoint of Eichner’s, Cummer’s, and Miyaji’s classifications for missing dentition.
