Abstract

Background: Changes in the level of salivary magnesium could be of great clinical interest not only because of its relation with oral health but also with the physiological alteration occurring during pregnancy. The aim of this study was to investigate the effect of pregnancy on the salivary magnesium level and their relations to gingivitis.Materials and methods: Salivary samples were taken from 24 pregnant women, 17 non pregnant and 14 lactating women. Flow rate was calculated. The supernatant salivary samples were assayed using atomic absorption spectrophotometer. Gingival Index was applied for the assessment of gingival inflammation.
Results: Salivary magnesium concentration was significantly the lowest mean value during pregnancy, with decrease in concentration in the third trimester followed by a marked increase after labor reaching the normal level. Pregnant women had a significantly highest Gingival Index mean than other control groups. Very weak correlations were found between flow rate and (pregnancy and salivary magnesium). A positive correlation was recorded between gingivitis and pregnancy and a negative correlation between gingivitis and salivary magnesium. However, statistically all correlations were not significant.
Conclusion: The salivary magnesium is influenced by female sex hormone during pregnancy. Analysis of saliva may be applicable as an investigation means of the physiological alterations that occur during and after pregnancy.

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

Background and objectives: Gingivitis is the most prevalent oral problem associated with pregnancy, in addition to several salivary changes. This study was designed to find the effect of pregnancy on salivary chemical factors (calcium and magnesium concentrations)and flow rate, and compare the results with that of non-pregnant women.Methods: The samples consist of (118) females with age ranged from (20– 40) years (84 pregnant and 34 control, non-pregnant women). After collection of un stimulated saliva, the concentration of calcium and magnesium, and salivary flow rate were measured.Results: The means of salivary flow rate, calcium and magnesium concentrations of pregnantand non-pregnant women were statistically non significant. There were non-significant difference between the means of each parameter with the age group of pregnant women and the gestation age. Non-significant difference between the means of each parameterwith the trimester of pregnancy.Conclusion: All factors showed non-significant differences between pregnant and non -pregnant women.
