Oral sugar clearance in children compared with adults.

The aim of the present investigation was to study oral sugar clearance of various types of foodstuffs in children of different ages in comparison with adults. Thirty children and 20 adults were selected constituting five groups, each containing 10 individuals: 3-, 7-, 15-years-olds and adults, all with normal salivary secretion rate, and adults with low salivary secretion rate (dry mouth patients). Oral sugar clearance was studied using three glucose-containing products: solution, tablet and biscuit. Repeated saliva samples were collected every other minute, between 1 and 11 min after the intake, with a convenient method suitable for very young children. For that purpose, a small circular paper disc, absorbing approximately 20 microliters of saliva, was placed under the tongue for 10 s. The glucose concentration of the samples was then analyzed enzymatically. The results showed that, in children, the oral sugar clearance became faster with increasing age. The adults and the 15-year-olds had similar patterns of clearance, while the dry mouth patients had the slowest oral clearance of all groups. The 3- and 7-year-olds showed the greatest variation in oral clearance between the various foodstuffs; the solution had faster clearance than both the biscuit and the tablet. The main conclusion from this study is that young children (3- and 7-year-olds) have both slower salivary sugar clearance and larger variation in clearance among various foodstuffs than older children and adults.

Saliva tests in the prognosis of caries in children.

The purpose of the investigation was to find out whether the negative correlations between caries indices and the flow rate, pH and buffer effect of saliva that could be demonstrated in groups of 8- and 5-year-old children, were close enough to allow prediction of the development of caries in a given child. The results showed that the range of variation of the results of all analyses were very wide. This makes the use of saliva tests alone in the prognosis of caries development of less value in the individual child.

An epidemiological study of child health and nutrition in a northern Swedish county. VII. A comparative study of general and dental health, food habits and socio-economic conditions in 4-year-old children.

A study of the general and dental health and the food habits of randomly selected 4-year-old Swedish urban children was performed. The results were compared with the findings of an investigation carried out four years earlier in the same area. In comparison with the earlier study no significant differences were found in haemoglobin values, packed red cell volume, microsedimentation rate and anthropometric measurements. The food habits had altered. A reduction in the frequency of between-meal consumption, particularly of sweets and soft drinks, as well as a reduction of the frequency of meat, fish and egg consumption was found. The children had an increased sandwich and milk consumption. The caries frequency was markedly reduced, which might be explained by the decreased between-meal consumption and an increased consumption of fluoride tablets. The food habits and the caries situation were generally influenced by the parents' socio-economic conditions, especially their educational level.

A descriptive and comparative study of oral health in 8-year-old Swedish children.

The aim of the study was to assess the oral health of a group of children, and to compare the findings with the results from an investigation performed 4 years earlier in children of the same age and living in the same area. The material consisted of 149 randomly selected 8-year-old children. The study included examination of caries and the state of the gingival conditions, enamel hypoplasia and opacities, supragingival calculus and extrinsic stains. Determinations were also made of the rate of secretion, pH and buffer effect of stimulated saliva. Socio-economic data and anamnestic dental data were noted. The investigation showed a decrease in caries frequency in the primary teeth, but not in the permanent teeth, during the four-year-period. As in the former investigation, regression analyses showed a negative correlation between the level of education of the parents and caries indices, and that the variation of the gingival indices could be explained by socio-economic factors. In addition, a negative correlation was found between the caries index for primary teeth and the rate of secretion of the saliva and the presence of supragingival calculus.

Caries prevalence after submandibular duct retroposition in drooling children with neurological disorders.

This study is a long-term follow up of 17 patients surgically treated for uncontrolled drooling, by retroposition of the ducts from the submandibular glands. Mean age was 16.8 years (range 7-31), with an average postoperation time of 9.2 years (range 1-18). Clinically, no subject revealed an impression of an extremely dry mouth, but most patients showed obvious permanent decrease in drooling after the surgical treatment. They had a highly significant increase in caries prevalence of the mandibular incisal and canine area, and this caries prevalence was related to the severity of cerebral palsy.
