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 13th survey included 13,654 new patients (5,889 male and 7,765 female patients) who visited the 56 member clinics (across 25 prefectures) during the period between January 1st and December 31st, 2018. 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 continued to decrease across all age groups above 12 years old; the prominent decrease of male smoking population across all age groups continued; and the number of remaining teeth continued to increase across age groups above 65 years old in both male and female population.
