We investigated the possible linkage between the crystallinity and elemental ratios (Mg/Ca and Sr/Ca) of the femoral cortical bones of rats with chronic kidney disease (CKD) or diabetes mellitus (DM). The Mg/Ca and Sr/Ca ratios were measured by using the laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS) technique and the crystallinity was evaluated by Raman spectroscopy on the same sample slice. The measured crystallinity varied significantly along the radial direction, reflecting the heterogeneities in the Mg/Ca ratio for the bone samples. For the endosteal cortical bone of CKD rats, the Mg/Ca ratio became higher. This is explained by the increase of the abundance of Mg in the bone, possibly due to the higher absorption efficiency of Mg in the intestine or due to the lower excretion efficiency of Mg from the kidney. For areas with a higher Mg/Ca ratio, the crystallinity of the bone was significantly more degraded than that for areas with a lower Mg/Ca ratio, suggesting that the substitution of Ca by Mg induced the deterioration of the crystallinity of hydroxyapatite (HAp). In addition, the measured Mg/Ca and Sr/Ca ratios of the bone were positively correlated with those found in serum samples. The data obtained here demonstrated that the metabolic alterations for inorganic elements caused the ionic substitutions of Ca by foreign cationic ions, and that the contents of foreign ions in the bone greatly affected the crystallinity of HAp.

Resin adhesion strengths to zirconia ceramics after primer treatment with silane coupling monomer or oligomer 査読

Resin bonding to zirconia ceramics is difficult to achieve using the standard methods for conventional silica-based dental ceramics, which employ silane coupling monomers as primers. The hypothesis in this study was that a silane coupling oligomer a condensed product of silane coupling monomers would be a more suitable primer for zirconia. To prove this hypothesis, the shear bond strengths between a composite resin and zirconia were compared after applying either a silane coupling monomer or oligomer. The shear bond strength increased after applying a non-activated ethanol solution of the silane coupling oligomer compared with that achieved when applying the monomer. Thermal treatment of the zirconia at 110 degrees C after application of the silane coupling agents was essential to improve the shear bond strength between the composite resin cement and zirconia.

Objectives. Dental ceramic surfaces are modified with silane coupling agents, such as gamma-ymethacryloxypropyl trimethoxy silane (gamma-MPTS), to improve bond strength. For bonding between lithium disilicate glass ceramic and resin cement, the objective was to investigate if 8-methacryloxyoctyl trimethoxy silane (8 -MOTS) could yield a similar performance as the widely used gamma-MPTS.
Methods. One hundred and ten lithium disilicate glass ceramic specimens were randomly divided into 11 groups (n = 10) according to pretreatment regime. All specimens were pre-treated with a different solution composed of one or a combination of these agents: 10 or 20 wt% silane coupling agent of gamma-MPTS or 8 -MOTS, followed by a hydrolysis solution of acetic acid or 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP). Each pretreated surface was luted to a stainless steel rod of 3.6 mm diameter and 2.0 mm height with resin cement. Shear bond strength between ceramic and cement was measured after 24-h storage in 37 degrees C distilled water.
Results. 8 -MOTS produced the same bonding performance as gamma-MPTS. Both silane coupling agents significantly increased the bond strength of resin cement, depending on their concentration. When activated by 10-MDP hydrolysis solution, 20 wt% concentration produced the highest values (gamma-MPTS: 24.9 +/- 5.1 MPa; 8 -MOTS: 24.6 +/- 7.4 MPa). Hydrolysis with acetic acid produced lower bond strengths than with 10-MDP.
Significance. Silane coupling pretreatment with 8 -MOTS increased the initial bond strength between lithium disilicate glass ceramic and resin cement, rendering the same bonding effect as the conventional gamma-MPTS.
