| Research Abstract |
The purpose of this study was to clarify the dietary habits of children, 4212 children, aged three to fifteen year, who visited 29 university dental hospitals all over Japan and who were investigated by means of a questionnaire during June and July of 1996.
A portion of the results were as follows.
1) Children three to five years old had breakfast everyday, but 15% of the children thirteen to fifteen years old sometimes did not.
2) 30 - 50% of the children watched T.V.program while they were eating breakfast.
3) Children three to twelve years old had dinner with their family, but 30% of the children thirteen to fifteen years old sometimes did not.
4) About 55% of the children three to five years old talked with family while they were eating dinner and about 45% watched T.V.program while eating. About 35% of the children thirteen to fifteen years old talked with family and about 60% of them watched T.V.programs.
For evaluation of the function of the occlusion and the masticatory function of the child, it is necessary to know their standard values. To discover these, the function of the occlusion were measured using the bite pressure detection film "Dental Prescale" and "Occluzer" system (Fuji Photo Film Co.) while the masticatrory functions were measured using three types of masticatory jellies (Sunstar Co.) in 871 children with normal occlusion (421 boys and 450 girls, Hellman's Dental Stage IIA, IIC, IIIA, IIIB, IIIC and IVA). For evaluation of the functions of the occlusion and the masticatory functions, the values obtained in the study are recommended as the standard values.
