| Popis: | The aim of this study was to measure the strontium levels in surface and subsurface artificially decalcified enamel exposed in situ to a strontium-supplemented toothpaste. Twenty healthy premolar teeth extracted for orthodontic reasons were cut into blocks and demineralized. The samples were cemented to the teeth of six volunteers who brushed with a hydroxyapatite (HAP) and HAP strontium-supplemented toothpaste for 3 and 6 mo. The strontium content in the enamel surface and in the lateral wall of the enamel samples was evaluated using energy-dispersive spectrometry microanalysis. After 3 mo, the strontium content in the enamel surface increased significantly compared to baseline values. On the lateral enamel surfaces, the strontium level was the same in all of the layers after 6 mo and was higher than the level observed after 3 mo. Regular toothbrushing with a strontium-supplemented toothpaste has been found to increase the strontium content in the exposed enamel, which can be an advantage in the prevention of cariogenesis. |
