在文献中，复合牙周围继发龋的报道较多。因此，氟化复合材料是令人感兴趣的材料，因为它们可以减少或抑制继发性龋齿。在这篇文章中，在原位模型调查中，F-释放复合材料对釉质脱矿周围的人工间隙的200微米的宽度进行了量化1个月后。复合材料的氟化物含量在0和26体积%之间变化。释放的氟化物的有益效果在差距中比在外釉质表面处更大。在差距中，所有氟化复合物相对于非氟化对照在统计学上显著地减少釉质脱矿。显微放射摄影显示病变深度值减少27- 45%，矿物质损失值减少25- 56%。在人工间隙旁边的外牙釉质表面，仅在最氟化的复合物附近可测量到有益的氟化效果。结果表明，氟化复合材料可能在未来的继发龋预防中发挥作用。
In the literature, secondary caries around composite restorations is reported often. Fluoridated composites are therefore interesting materials because they might reduce or inhibit secondary caries. In this article an in situ model investigation is presented in which the effect of F-releasing composites on enamel demineralisation around an artificial gap of 200 microns width was quantified after 1 month. The fluoride content of the composites varied between 0 and 26 vol%. The beneficial effect of the fluoride released was larger in the gap than at the outer enamel surface. In the gap, all fluoridated composites reduced the enamel demineralisation statistically significantly with respect to the non-fluoridated control. Microradiography showed a reduction of lesion depth values of 27-45%, and a reduction of mineral loss values of 25-56%. At the outer enamel surface next to the artificial gap, a beneficial fluoridation effect was measurable only near the most fluoridated composite. The results indicate that fluoridated composites may play a role in the future prevention of secondary caries.
