Periodontal disease morbidity of the first-visit patients at dental clinics and the efficacy of periodic care-management

Kenji Oka, Yukiko Oka, et al.

This report reviews morbidity rate of periodontal disease, tendency of DMFT and the number of present teeth, and efficacy of caries prevention, periodontal disease prevention, periodontal disease treatment, and periodic management. The following data have been used for making evaluation; the Survey of Dental Diseases in 1999 (6,903 samples; Ministry of Health, Labour and Welfare), Suita-city (Osaka Pref.) Adult Dental Examination (12,955 samples), and author's patients data (4,674 samples; the patient's data including severity of periodontal disease were rated by the protocol incorporated in "Wistaria", a template of a database-software that facilitates clinics managing patients-data, which the Japan Health Care Dental Association offered exclusively for the member).

No great discrepancy was observed among these three data as for present-teeth number and DMFT for each age, when compared with the data of author's patients data of initial-visit. From the data of Research of Dental Diseases Actual Condition, it is recognized that teeth loss is rapidly accelerated at the age over 50, since tooth strength is almost suddenly lost and becomes vulnerable at this age due to repetitive treatment aimed at early-stage caries detection and treatment. Therefore, this data also shows the evidence that appropriate periodontal treatment and/or periodic care-management have not been provided. The data of "Health and Welfare Trend Research"(Ministry of Health, Labour and Welfare) also underwrites this fact. From the data of 1,176 patients (the mean age at the first visit; 45.6 years old) visiting author's clinic for periodic care-management, it has been obsereved that mean number of teeth loss per patient is 0.3 in the period of average 6.4 treatment years and 80.3% of the patients among them experienced no teeth loss during the same period. In analysis of 396 patients who had deciduous teeth and mixed dentition at the first visit, DMFT changed from 0.9 to 1.3 and caries-free rate became from 66.1% to 61.9% after average 5.9 years periodic care-management. The lower the first-visit age DMFT increase can be well controlled and caries-free rate can be maintained at higher level.

It has been well observed that periodic care-management contributes to adult teeth loss incredibly and to lessen DMFT increase greatly.
