Abstract
A collective statistical study on dental treatment and periodical examination in the Gifu prefectural institution for the handicapped during the year 1978-1982was made. The reports served as a basis for analyzing the trends of dental services for the institutionalized crippled and developmentally disabled children. The subjects comprised a total of 479 children from 4-19 years of age.
The results were as follows:
1. The percentage of the cerebral palsyed children among the handicapped was approximately 80% during the year 1978-1982.
2. The mean number of treated carious teeth was 4.1 in 1978, and it gradually decreased to 2.6 in 1982.
3. In regard to the content of the dental services, the extraction of the deciduous teeth was the highest, up to 50.9% in 1978. However the more preventive procedures such as fluoride solution, diammine silver fluoride application and restorative work were greatly employed in the following years.
4. The most commonly preferable restorative work for deciduous teeth was the metal crown followed by amalgam, while amalgam was the most frequently applied restorative measure for the permanent teeth.
5. The vital pulpotomy with calcium hydroxide was the most frequently performed endodontic treatment for deciduous teeth.
6. The recall time for the patient was only 0.4 times per year in 1978, however it increased to 2.2 in 1982, and consequently the oral condition of the patients was much improved.
