In 1, 134 children 3 years of age in the metropolitan Tokyo area, the relationship between the prevalence of carious teeth and food intake was statistically analyzed. Food intake was studied after classification of intake into main meals and between-meal food. The frequency of between-meal food intake was classified into“once”, “twice”and“three or more times”a day groups, and the mode of eating into“regular”, “somewhat regular”and“irregular”. The preference for sweets was classified into“liking sweets”, “liking both sweets and non-sweets”and“not liking sweets. ”The prevalence of carious teeth tended to be higher as the frequency of intake became higher, the mode of eating irregular and the preference for sweets more pronounced. The most profound influence on the prevalence of carious teeth was exerted by the frequency of intake, followed by the preference for sweets and mode of eating. The influence of the frequency of intake, mode of eating and sweet preference was most distinctly reflected on the prevalence of carious teeth on the occlusal surface of the molars and the neighboring and labial surface of the anterior teeth. This tendency was especially pronounced on the occlusal surface of the molars. As to the relationship between the sweet preference and frequency of intake between-meal food, the prevalence of carious teeth tended to be higher as the tendency of“liking sweets”and the tendency of“liking both kinds of foods”plus the frequency of the intake became higher. In the group of“not liking sweets”, the caries rate did not increase very much even if the frequency of intake was increased. As to the relationship between the tendency to like between-meal food and the mode of eating, the caries rate tended to be higher in the group of“liking sweets”and that of an“irregular feeding”In the groups of“liking both sweets and non-sweets”and“not liking sweets”, no difference was noted in the caries rate regardless of the mode of eating. Among the various factors affecting food intake, however, the expense for between-meal food, the amount of intake at the main meals, appetite, and biased intake failed to show significant relation to the caries rate. These results indicate an especially intimate relationship between the frequency of betweenmeal food intake, mode of eating or tendency to like sweets and the prevalence of carious deciduous teeth.
