The Indicators of Molar Coefficients of the Chemical Elements in Dentin and their Correlation with Enamel

Abstract

Objectives:Determination of molar coefficients of the chemical elements in dentin, their possible correlation with tooth enamel. Material and Methods:There were examined 29 clinically extracted teeth of both jaws and their longitudinal sections (12 clinically intact teeth, 10 teeth with wedge-shaped defects, 7 teeth with cervical caries) of the patients aged 25to 54 with the help of JSM-6490 LV focused beam electron microscope (scanning) with system of energy-dispersive X-ray microanalysis. We have determined the chemical composition of 290 enamel areas and 235 dentine areas in the incisal region (tubercle), equator, cervical area as a percentage of the weight amounts of carbon, oxygen, calcium, phosphorus, sodium, magnesium, sulfur, chlorine, zinc, potassium, aluminum, we have identified their molar coefficients. Results: The chemical composition of dentin differed in the values of Na/Mg, Al/Zn, Mg/Ca, K/Na (p≤0.05) in all studied topographical regions of the samples. Higher values of Na/Mg and lower values of Al/Zn were identified in the teeth with cervical caries (p≤0.05). Correlation was found in dentin: inverse between Ca/P and P/Ca, Mg/Ca and Na/Mg, Ca/Mg and Mg/Ca, Mg/P and Na/Mg, Mg/P and Ca/Mg, direct between Ca/Mg and Na/Mg, Mg/P and Mg/Ca (p≤0.05). High correlation was determined between molar coefficients in enamel and dentin: Mg/Ca and Mg/P (direct), Ca/P and P/Ca (inverse), p<0.0001. Conclusions:The differences in the indicators of molar coefficients in dentin, their correlation with enamel are probably associated with the peculiarities of the pathological processes in the cervical region and it requires further study.
