The aim of the present in vivo study was to compare efficacy of light-cured resin-modified glass ionomer liner, Vitrebond™ (3M ESPE) with Dycal® (Dentsply) on the healing of pulpal tissue in the event of a direct iatrogenic pulpal exposure.
Experimental group consisted of Vitrebond™ (3M ESPE) resin-modified glass ionomer liner, and Vitremer™ (3M ESPE) resin-modified glass ionomer cement (GIC) in comparison with the control group of Dycal® (Dentsply) as liner and Poly F® (Dentsply) dental cement. Class V cavities were prepared in 32 sound premolars that were scheduled for orthodontic extraction, and the exposures were capped according to groups. Five teeth from each group were extracted under local anesthesia after an interval of 24 hours, 35 and 60 days, and evaluated for inflammation, fibrotic changes, formation of reparative dentin and bacterial examination.
The present study did not show any statistically significant difference between two groups in terms of inflammation, fibrosis, reparative dentin formation, and bacterial examination.
This study shows that Vitrebond™ (3M ESPE) light-cured resin-modified glass ionomer liner can be used as an alternative to calcium hydroxide as a direct pulp capping material.
Light-cured resin-modified glass ionomer liner can be an alternative for the calcium hydroxide-based liner for capping iatrogenic pulp exposures.
本体内研究的目的是比较光固化树脂改性玻璃离子衬层材料Vitrebond™（3M ESPE公司）和Dycal®（登士柏公司）在直接医源性牙髓暴露情况下对牙髓组织愈合的效果。
实验组采用Vitrebond™（3M ESPE公司）树脂改性玻璃离子衬层材料和Vitremer™（3M ESPE公司）树脂改性玻璃离子水门汀（GIC），对照组采用Dycal®（登士柏公司）作为衬层材料和Poly F®（登士柏公司）牙科水门汀。在32颗计划正畸拔除的健康前磨牙上制备V类洞，并根据分组对暴露部位进行覆盖。每组分别在24小时、35天和60天后在局部麻醉下拔除5颗牙齿，评估炎症、纤维化改变、修复性牙本质形成情况并进行细菌检查。
本研究显示两组在炎症、纤维化、修复性牙本质形成和细菌检查方面均无统计学显著差异。
本研究表明，Vitrebond™（3M ESPE公司）光固化树脂改性玻璃离子衬层材料可作为氢氧化钙的替代品，用作直接盖髓材料。
光固化树脂改性玻璃离子衬层材料可替代基于氢氧化钙的衬层材料用于覆盖医源性牙髓暴露。
