比较新型晶须增强实验复合树脂与树脂改性玻璃离子水门汀（RM-GIC）对人天然龋和人工龋样牙本质病变的修复作用。制备了10颗中度自然牙本质龋的磨牙（N）。在10个无龋磨牙的咬合牙本质中制备人工龋样牙本质损伤，并在pH=4.3下脱矿48 h（A）。用ART复合材料或RM-GIC修复。将所有修复牙切成120 μm的切片。采用X线片结合数字图像分析技术，分析去矿化/去矿化处理前、4周和8周后标本同一部位的骨密度变化。4周和8周后的平均再矿化百分比±标准差为：N：ART-复合：27±9，46±14; RM-GIC：18±6，36±11; A：ART-复合：48±9，66±11; RM-GIC：50±13，62±11。对于自然龋的再矿化，ART-复合材料与RM-GIC之间有显著性差异（p<0.05）。两种充填剂对天然龋和人工龋的矿化度有显著性差异（P<0.001）。ART复合材料和RM-GIC对天然龋和人工龋的修复效果不同，这很可能是由于龋牙本质的微观结构和组成不同。
To compare the remineralization of human natural caries and artificial caries-like dentin lesions from a novel whisker-reinforced experimental composite resin to a resin-modified glass ionomer cement (RM-GIC) as control. Ten molars with moderate natural dentin caries were prepared (N). Artificial caries-like dentin lesions were prepared in occlusal dentin of ten caries-free molars and demineralized at pH=4.3 for 48 h (A). The cavities were restored with ART-composite or RM-GIC. All restored teeth were sliced into 120-μm sections. Transverse microradiography combined with digital image analysis was performed to analyze the change in mineral density at the same position of the specimens before, after 4 weeks and 8 weeks remineralization/demineralization treatment. The mean percent remineralization ± standard deviation after 4 weeks and 8 weeks are: N: ART-composite: 27±9, 46±14; RM-GIC: 18±6, 36±11; A: ART-composite: 48±9, 66±11; RM-GIC: 50±13, 62±11. For the remineralization of natural caries, there was a significant difference between ART-composite and RM-GIC (p<0.05). For both restoratives there were significant differences between remineralization of natural and artificial caries (p<0.001). ART-composite and RM-GIC remineralized natural and artificial caries differently most likely due to differences in microstructure and composition of caries dentin.
