Abstract
This survey was conducted to investigate oral health status of new patients at dental clinics practicing routine maintenance. Subjects were collected in anonymised digital format from Japan Health Care Dental Association (JHCDA) member clinics. The subjects of this 15th survey included 12,919 new patients (5,725 male and 7,194 female patients) who visited the 59 member clinics (across 26 prefectures) during the period between January 1st and December 31st, 2020. For children and minors, the DMFT scores were recorded, and for adults the DMFT scores, the number of remaining teeth, the condition of periodontal tissues and smoking status were recorded. As a result, the DMFT index continues to decrease in all age groups above 12 years, the marked decrease in male smokers continues in younger age groups, and the number of remaining teeth continues to increase in both men and women above 65 years of age.
