Abstract

Magnesium is one of the major cations in plant and animal tissues and is anessential constituent of the bone and tissue, as well as the body fluids. Concentrationsof most electrolytes in saliva are subjected to considerable alteration. The aim of thisstudy was to investigate the salivary magnesium in relation to dental caries. A sampleof 46 adults was involved with age range of 20-45 years. Samples of stimulated salivawere collected and prepared to be analyzed for magnesium estimation using atomicabsorption spectrophotometer. Clinical examination was done for dental caries usingWHO criteria. The salivary magnesium concentration was 0.38mg/dl. Neither the sex,nor the age influenced the concentration of magnesium in supernatant stimulatedsaliva. Negative correlations were found between salivary magnesium and age,salivary flow rate, while, a positive correlation was recorded with dental caries. Allthese associations were not proved to be significant (P<0.05). Further investigationshould be done on whole saliva to clarify the association between magnesium anddental caries. The magnesium relation with the other elements must be considered.

Abstract

The most dramatic increase in dental decay is thought to have occurred during thelast part of the 19th and the beginning of the 20th centuries. The aim of this study wasto investigate the caries experience and pattern in primary and permanent teeth in alongitudinal study. Dental caries of 166 kindergarten children of 4-5 years old wasrecorded. Only 122 of the children were re-examined when their ages became 10-11.The third examination of 118 children was done when their ages became 13-14.Dental caries registration was done following the criteria of WHO (1987). Dentalprevalence was increased by age reaching 94.9 percent at 13-14 years old. No sexdifferences were observed among the three examinations except in DMFT. TheDMFT incidence after 6 years was 4.3 and after 3 years was 1.8, while DMFSincidence was 6.4 and 2.2 respectively. The D/d component was the highest meanvalue. Although dental caries was significantly higher in posterior than in anteriorteeth, there were no jaw differences. Occlusal and proximal surfaces were thepredominate surfaces affected among permanent and primary teeth respectively.Coinciding with the incline in caries experience observed among children, changes inthe distribution and progression rate of the disease have been found.

Abstract

Background: Nutritional status is the mirror image of health and one of its mostaccurate indicators. Normal salivary gland functions are essential for maintenanceof oral health. Salivary flow rate and composition which could be influenced bynutritional status. The aim of this study was to investigate the effect of nutritionalstatus on Streptococcus mutans and their relations to dental caries.Materials and methods: Stimulated saliva was collected from 28 children with anage 6 years old. Those randomly selected children were divided into wellnourishedand chronic malnourished children according to their age, weight andheight indicators. Dental caries examination of primary teeth was assayedfollowing the criteria of WHO. Microbiological assessment of Streptococcusmutans was done after measuring the salivary flow rate.Results: No significant differences were found between well-nourished and chronicmalnourished children in caries experience. Chronic malnourished children had asignificant lower salivary flow rate and higher mean counts of salivaryStreptococcus mutans than that of well-nourished children. Significantcorrelations were found between nutritional status with flow rate andStreptococcus mutans.Conclusion: Early identification of malnourished children will lower the prevalenceof dental caries and enhance their quality of life.
