Indiana University-Purdue University Indianapolis (IUPUI) / Reports differ concerning the cariogenic potential of milk. Some authors indicate that plain milk can cause dental caries, while others believe that the disease results from adding carbohydrates to the milk. Still others suggest that milk has a protective effect and may contribute to caries prevention. The present study investigated the capability of human milk, plain bovine milk, a milk formula, and milk with honey to produce caries-like lesions in an environment which simulated the oral cavity. Four groups of eight sound bicuspids each, which had been extracted for orthodontic reasons, were mounted in a mouth simulator. The teeth and complete apparatus were sterilized with ethylene oxide. The teeth were then inoculated with human saliva and covered with linen cloth to facilitate bacterial colonization. Each day the various groups of study teeth were exposed to one of the four milk solutions during a 2, 4, or 8-hour period. After each period, a sterile chemical solution simulating human saliva was dropped (8-12 ml/hr) over the cloth to provide a mouth-like environment. A control group was not exposed to a milk preparation. The results indicate that after six weeks, all milk solution groups showed unequivocal signs of decalcification, with an intensity proportional to the period of exposure to the study solutions. Plain bovine milk produced the least decalcification, followed in order by milk formula, human milk, and milk and honey. It can be inferred, from these results, that milk itself, without addition of extra carbohydrates, has the potential to produce dental caries if left stagnant over the tooth surfaces for a sufficient time.

Indiana University-Purdue University Indianapolis (IUPUI) / Previous studies have suggested a positive relationship between the amount of readily fermentable carbohydrate and the dental caries experience. The frequency of eating and the amount of carbohydrate consumed between meals have also been considered in previous studies but the results have been controversial and contradictory. From 7 day diet records of 200 children the frequency of eating was determined, and the total sugar intake and the between meal sugar was calculated as to its carbohydrate equivalent of teaspoons of sugar. The dental caries experience of these children was determined from the clinical examination records and periapical and bite wing radiographs and recorded as DMFS. The average total sugar intake of these children was 164 teaspoons while the average between meal sugar was 55 teaspoons. A correlation between the total sugar consumed and the DMFS showed that the relationship was not statistically significant. The total between meal sugar intake showed the highest correlation with the DMFS. The frequency of between meal eating did not show a statistically significant effect on the dental caries experience. A slight negative relationship was obtained between the total sugar intake and the milk intake, indicating that as the milk intake tends to increase, the sugar tends to decrease and vice versa. A multiple correlation between DMFS and the total sugar and total milk intake showed a negative correlation coefficient. The children residing in the city had a higher DMFS than the rural children of comparable ages.

There is a general agreement that food habits change over time. This has been clearly shown in studies conducted in first world countries, but until recently this information has been lacking in South Africa, particularly among preschool children, although nutrition information is available on dietary intake at a particular point of time in some groups. Changing food habits may affect disease. With the rapidly changing socio-political situation in South Africa diet too must have changed and one cannot rely on previous nutritional information. New reliable information is needed to help plan future health needs of all South Africans. Dietary intake in association with dental health has been studied by numerous investigators. Regarding energy and specific nutrients, studies have thus far shown no relationship of energy to dental caries incidence; carbohydrate, particularly sugars, have shown both positive and negative relationships to caries incidence and indirectly dietary fats may be associated with low caries because fat and sugar intake are inversely proportional to each other. The role of trace elements has varied from caries promoting to cariostatic. It is clear though that because of the complex nature of the caries process, carbohydrate intake, together with other macro- and micronutrients, does not fully explain the development of this disease. This could be influenced by the fact that most of the studies conducted on diet and dental health have been cross-sectional. The Vipeholm study in Sweden, the Hopewood House study in Australia and more recently the Michigan study in the United States are the only longitudinal studies that have examined the association between diet and dental caries incidence and both the Vipeholm and Hopewood House studied only selected groups in institutions. Until now no true longitudinal study had been conducted among South African preschool children regarding the association between diet and the development of dental caries. The Birth-to-Ten study is the first such longitudinal study that selected a random sample representative of the population groups in the country and has provided unique information on the longitudinal dietary intake together with the dental health at 1- and 5- years. In addition no South African study has looked at the impact of past diet on the present dental health of the same South African children and the Birth-to-Ten study provided this opportunity.
