背景
对炎症牙髓盖盖的可靠性存在很大争议。特别是，氢氧化钙作为封闭剂的使用受到了质疑。在这项研究中，将炎症牙髓直接盖盖或部分牙髓切除后形成的硬组织屏障与氢氧化钙或粘结树脂进行比较，并在没有附加封闭剂或IRM表面封闭剂的情况下进行比较。共使用了5只狗的70颗牙齿。10颗未经治疗的牙齿作为阴性对照。在60颗牙齿中，在牙髓附近准备一个空洞，并将浸泡在其中的棉球封闭1-2周，以诱导牙髓炎。然后，将牙洞重新进入并延伸，以暴露牙髓。
材料和方法
其中一半牙(n=30)行部分牙髓切断术，另一半(n=30)行浅表暴露牙髓治疗。两组牙髓修复程序相同：(1)氢氧化钙+银汞合金+IRM表面封闭；(2)OptiBond Solo，Prodigy加IRM表面封闭；(3)OptiBond Solo，Prodigy不加IRM表面封闭。对硬组织屏障的存在、缺失和质量进行组织学评估。
结果
氢氧化钙组在统计学上优于所有其他组。IRM表面封闭显著改善了愈合情况。虽然直接盖髓和部分切髓在统计学上没有显著差异，但功率统计表明，在临床实践中，部分切髓将是更可取的。临床意义这项研究的结果表明，部分牙髓切断术、氢氧化钙药物和无菌冠状修复是一种可行的覆盖炎症牙髓的技术。
BACKGROUND
A great deal of controversy exists regarding the reliability of capping the inflamed pulp. In particular, the use of calcium hydroxide as a capping agent has come into question. In this study, hard tissue barrier formation after inflamed pulps were capped directly or after partial pulpotomy was compared with calcium hydroxide or bonded resin and with no additional seal or an IRM surface seal. Seventy teeth in five dogs were used. Ten untreated teeth were used as negative controls. In 60 teeth, pulpal inflammation was induced by preparing a cavity close to the pulp and sealing a cotton pellet soaked in plaque in it for 1 to 2 weeks. The cavities were then re-entered and extended to expose the pulps.
MATERIALS AND METHODS
In half the teeth (n = 30) a partial pulpotomy was performed and in the other half (n = 30) pulpal treatment was performed on the superficial exposed pulp. Both pulpal treatment groups received the same restorative procedures: (1) calcium hydroxide + amalgam + IRM surface seal; (2) OptiBond Solo, Prodigy with IRM surface seal; or (3) OptiBond Solo, Prodigy without IRM surface seal. The presence, absence, and quality of a hard tissue barrier were evaluated histologically.
RESULTS
The calcium hydroxide groups were statistically superior to all other groups. The IRM surface seal resulted in significantly better healing. Although there was no statistically significant difference between direct pulp capping and partial pulpotomy with the numbers in this study, power statistics indicated that in clinical practice a partial pulpotomy would be preferable. CLINICAL SIGNIFICANCE The results of this study suggest that a partial pulpotomy, calcium hydroxide medicament, and a bacteria-tight coronal restoration represent a viable technique for capping the inflamed pulp.
