Results of this study showed no correlation between the thickness or amount of reparative dentin deposited and the type of dental restorative material placed at either 5 or 8 weeks in controlled Class V cavity preparations in monkey teeth. Factors such as preparation trauma from the bur, operator hand instrumentation, and microleakage of bacterial toxins played a greater role in the stimulation of reparative dentin than did material irritation or toxicity. Some differences in the thickness of the reparative dentin deposited were noted when teeth were grouped according to the amount of remaining dentin.
本研究结果表明，在对猴牙进行的V类窝洞制备的对照实验中，在5周或8周时，修复性牙本质沉积的厚度或数量与所放置的牙科修复材料类型之间没有相关性。与材料刺激或毒性相比，诸如牙钻制备创伤、术者手工操作以及细菌毒素微渗漏等因素在刺激修复性牙本质形成方面发挥了更大作用。根据剩余牙本质的数量对牙齿进行分组时，发现修复性牙本质沉积厚度存在一些差异。
