据报道，几种新的粘合系统可以促进强粘合力。这项体内研究涉及用两种 V 类空腔制剂的实验粘合系统对三只食蟹猴的牙齿进行治疗，并报告与每种治疗相关的牙髓反应和微生物侵入程度。每只猴子的左上象限牙齿均使用含有 2.5% 硝酸铝 + 1.5% 草酸 + 4.9% NPG 的实验溶液进行处理，然后应用 PMDM 和 Silux XL™ 复合材料。右下象限使用包含 5.7% NPG + 2.$% 硝酸的实验溶液进行处理，然后使用 PMDM 和 Silux XL™ 复合材料进行处理。右上象限和左下象限用临床材料处理以建立阳性和阴性对照。 4、25 和 59 天后，拔除牙齿并进行常规组织学和细菌学评估。表面和深层反应均出现轻微病理状况，但到第 59 天时所有值均接近 0.0。仅 12% 的修复体中发现微生物。这两种实验系统对于人体临床试验似乎都是安全的。
Several new bonding systems have been reported that promote strong adhesion. Thisin vivostudy involves treatment with two experimental bonding systems of Class V cavity preparations in the teeth of threeMacaca fascicularisprimates and reports the pulpal responses and degree of micro-organism invasion associated with each treatment. In each monkey, the teeth in the upper left quadrant were treated with the experimental solution, containing 2.5% aluminum nitrate + 1.5% oxalic acid + 4.9% NPG, followed by application of PMDM and Silux XL™ composite. The lower right quadrant was treated with the experimental solution, containing 5.7% NPG + 2.$% nitric acid, followed by PMDM and Silux XL™ composite. The upper right and lower left quadrants were treated with clinical materials to establish positive and negative controls. After four, 25, and 59 days, the teeth were removed and underwent routine histological and bacteriological evaluation. Slight pathological conditions were noted for superficial and deep responses, but all values approached 0.0 by the 59th day. Micro-organisms were seen under only 12% of the restorations. Both experimental systems appear to be safe for human clinical trials.
