The effects of XXXX intake and frequency of ingestion on dental caries increment in a three-year longitudinal study.

@entity1 @entity3363
A three-year longitudinal study was carried out with a group of @entity1 , initially aged 11-15, residing in non-fluoridated rural communities in south-central Michigan. This report analyzes the relation between caries increment and consumption of @entity3363 from all sources to see if accepted relationships have changed with the caries decline in the United States. There were 499 @entity1 who provided three or more 24-hour dietary recall interviews, and who received dental examinations at baseline and after three years. Caries increment averaged 2.91 DMFS over the three years, with 81% of new lesions on pit-and-fissure surfaces. Consumption of @entity3363 from all sources averaged 156 g per day for males and 127 g per day for females, an average of 52 kg per @entity1 per year. @entity3363 constituted one-quarter of total caloric intake for both @entity1 and @entity1 , and the average number of eating occasions per day was 4.3. @entity1 who consumed a higher proportion of their total energy intake as @entity3363 had a higher increment of approximal caries, though there was little relation to pit-and-fissure caries. The average number of daily eating occasions was not related to caries increment, nor was the average number of sugary snacks (defined as foods with 15% or more of @entity3363 ) consumed between meals, but the average consumption of between-meal @entity3363 was related to the approximal caries increment. When @entity1 were categorized by high caries increment compared with no caries increment, a tendency toward more frequent snacks was seen in the high-caries @entity1 .(ABSTRACT TRUNCATED AT 250 WORDS)
