本研究旨在观察和比较上海市民与大阪市民恒牙龋病的发病率。1996年对上海的3819人和1993年对大阪的484人进行了具有代表性的抽样牙科检查。研究对象的年龄范围为5至74岁。通过平均龋失补牙数（DMFT）和恒牙龋病发病率来了解研究对象的龋病患病情况。检查人员还记录了研究对象的龋病状况及治疗情况。结果显示，上海市民恒牙龋病发病率为59.82%，大阪市民为92.77%。上海市民的平均DMFT远低于大阪市民。该研究还表明，上海市民与大阪市民的恒牙健康率存在差异。上海市民为21.74%，大阪市民为12.21%。统计结果显示，上海市民与大阪市民的龋病治疗情况差异很大。上海有32.61%的龋病患者已补牙，而大阪这一比例为52.99%。这表明50岁以上人群的口腔健康状况有待提高，尤其是在上海市。
