The aim of the study was to assess the effect of glass ionomer fillings Fuji IX on the mineral content of the hard dental tissues of carious teeth treated by sparing methods.
The study material consisted of 4 deciduous teeth lost due to physiological resorption. The teeth had glass ionomer fillings Fuji IX inserted after treatment of caries by means of sparing methods (ART and CMCR). Chemical analysis of enamel and dentin was performed by means of energy dispersive spectroscopy (EDS) with X-ray analysis QUEST system at a distance of 20 um (point C) and 120 um (point D), respectively. The content of the following elements was evaluated in weight percent: oxygen (O), fluoride (F), sodium (Na), magnesium (Mg), aluminum (Al), silicon (Si), phosphorus (P), calcium (Ca), strontium (Sr). The Ca/P ratio was calculated. T-student test for pairs, with the level of significance p < 0.05, was used for statistical analysis of the results.
We found significantly higher levels of fluoride, aluminum and silicon and lower concentrations of calcium and phosphorus in the dentine adjacent to the filling (point C). However, no statistically significant differences were observed in the levels of the elements between these two sites of measurement.
Our results indicate that mineralization of the calcified dentine may involve elements released from glass ionomer cement Fuji IX.
本研究旨在评估玻璃离子水门汀Fuji IX对采用保守方法治疗的龋牙硬组织矿物质含量的影响。
研究材料包括4颗因生理性吸收而脱落的乳牙。这些牙齿在采用保守方法（非创伤性修复治疗和龋病控制再矿化疗法）治疗龋齿后，植入了玻璃离子水门汀Fuji IX。分别通过能量色散光谱仪（EDS）结合X射线分析QUEST系统，在距离20微米（C点）和120微米（D点）处对釉质和牙本质进行化学分析。以重量百分比评估以下元素的含量：氧（O）、氟（F）、钠（Na）、镁（Mg）、铝（Al）、硅（Si）、磷（P）、钙（Ca）、锶（Sr）。计算钙磷比。采用配对t检验，显著性水平p < 0.05，对结果进行统计分析。
我们发现，在靠近充填物的牙本质（C点）中，氟、铝和硅的含量显著更高，而钙和磷的浓度更低。然而，在这两个测量部位之间，元素水平未观察到统计学上的显著差异。
我们的结果表明，钙化牙本质的矿化可能涉及从玻璃离子水门汀Fuji IX释放的元素。
