Abstract：
In pediatric and operative dentistry, caries treatment benefits from a therapeutic option based on the use of silver fluoride (AgF) associated with potassium iodide (KI) to avoid dark colorations on dental tissues. The objective of this in vitro study is to evaluate the retention of glass ionomer cement (GIC) on a dentin when treated with AgF and KI. Twenty-two healthy human permanent molars and eight human primary teeth, all free of any decay, were cut to obtain occlusal flat dentinal surfaces and were then treated with AgF for a duration of 60 s. For half of the teeth, a drop of KI was applied for a duration of 30 s. All samples were covered with a plot of GIC and their resistance to shear bond strength was measured. The fracture resistance in both permanent and primary teeth does not show any statistically significant differences whether KI was applied or not. For permanent teeth, the resistance is slightly higher in the group treated with KI than in the group treated with AgF alone. To our knowledge, these data are the first to describe the possible application of KI both on primary and permanent teeth. In any case, further studies are needed to investigate the bond strength between dentin and GIC on a wider range of samples.
摘要：
在儿科和手术牙科中，龋齿治疗受益于基于使用与碘化钾（KI）相关的氟化银（AgF）的治疗选择，以避免牙齿组织上的深色。这项体外研究的目的是评估玻璃离聚物水泥（GIC）在用AgF和KI处理时在牙本质上的保留。22颗健康的人类恒磨牙和8颗人类乳牙,都没有任何衰变，被切割以获得咬合平坦的牙本质表面，然后用AgF处理60s。对于一半的牙齿，施加一滴KI持续30s。所有样品用GIC图覆盖,并测量它们的抗剪切粘结强度。无论是否应用KI，恒牙和乳牙的抗断裂性都没有显示出任何统计学上的显着差异。对于恒牙，KI治疗组的耐药性略高于AgF治疗组.据我们所知,这些数据首次描述了KI在乳牙和恒牙上的可能应用。无论如何,需要进一步的研究来研究更广泛样品中牙本质和GIC之间的结合强度.
