This study evaluated the pulp response to a tri-cure resin-modified glass ionomer cement and compared this response to those elicited by a zinc oxide-eugenol cement and a silicate cement. Materials were placed in nonexposed class V cavity preparations on human teeth.
Sixty premolars were selected in orthodontic patients in a voluntary group of teenagers. All cavities were prepared according to International Dental Federation specifications. Resin-modified glass ionomer and silicate applications were carried out according to the manufacturers' instructions.
All teeth were asymptomatic. Pulp responses to the resin-modified glass ionomer cement were slightly greater than to the zinc-oxide-eugenol cement. Bacterial staining attempts were inconclusive with regard to time intervals and pulp responses. No necrotic pulps were seen in any teeth.
The tri-cure resin-modified glass ionomer cement elicited a slightly greater adverse pulp response than did the zinc-oxide-eugenol cement with respect to the healing process of the pulp.
本研究评估了牙髓对一种三固化树脂改性玻璃离子水门汀的反应，并将该反应与氧化锌丁香酚水门汀和硅酸盐水泥引发的反应进行比较。将材料置于人牙未暴露的V类洞型制备中。
在一组青少年正畸患者中选择了60颗前磨牙。所有洞型均按照国际牙科联合会的规范制备。树脂改性玻璃离子和硅酸盐的应用按照制造商的说明进行。
所有牙齿均无症状。牙髓对树脂改性玻璃离子水门汀的反应略大于对氧化锌丁香酚水门汀的反应。关于时间间隔和牙髓反应，细菌染色试验结果不明确。在任何牙齿中均未观察到坏死牙髓。
就牙髓的愈合过程而言，三固化树脂改性玻璃离子水门汀引发的不良牙髓反应略大于氧化锌丁香酚水门汀。
