We previously reported on the accessibility of dental services in Japan using the Geographic Information System, evaluating the supply and demand for home dental care using a new approach based on previous methods. For this study, we obtained population data in 2019 from the Japanese National Census and data retrieved from the e-Stat website. In addition, we purchased data from the Kokusai Kogyo Company on dental clinics and offices specializing in home dental care in 2019. We further modified the dental accessibility indicators by adding transportation network information. The information we obtained for the new accessibility index ratio (AIR), data which was converted into traffic time, was considerably different from the previous data, which only considered the distance from dental clinics specializing in home dental care to the patients. The accessibility indicator we defined may be a useful tool for revealing the demand for and supply of home dental care in Japan. (J Osaka Dent Univ 2023; 57: 289-293)
