J Endod:冠折恒切牙牙髓切断术使用iRoot BP Plus或氢氧化钙的比较:一项回顾性研究

2020-02-15 lishiting MedSci原创

氢氧化钙作为常规牙髓切断术的盖髓材料已在临床应用许久,但其存在一定的缺点。iRoot BP Plus (Innovative Bioceramix Inc, Vancouver, Canada)是一种全新研发可即刻使用的硅酸钙类生物活性陶瓷材料,具有极佳的生物活性和封闭性能。然而,作为牙髓切断术的盖髓材料,在冠折断恒前牙中应用iRoot BP Plus的效果是否会优于氢氧化钙还未可知。

氢氧化钙作为常规牙髓切断术的盖髓材料已在临床应用许久,但其存在一定的缺点。iRoot BP Plus (Innovative Bioceramix Inc, Vancouver, Canada)是一种全新研发可即刻使用的硅酸钙类生物活性陶瓷材料,具有极佳的生物活性和封闭性能。然而,作为牙髓切断术的盖髓材料,在冠折断恒前牙中应用iRoot BP Plus的效果是否会优于氢氧化钙还未可知。研究共纳入了205颗冠折的恒切牙。这些牙齿均实施牙髓切断术,并按照使用的盖髓材料的不同随机分为2组(105 treated with iRoot BP Plus and 100 with calcium hydroxide)。在术后的12至24个月随访过程中,收集临床和X线影像结果。通过X线影像结果分析2组中修复性牙本质桥的形成和牙髓抹消情况变化。结果显示,2者在平均随访17.5 ± 4.4个月期间(12-24 months),牙髓切断术的治疗成功率存在显著性差异,iRoot BP Plus组为99%和氢氧化钙组为93%。iRoot BP Plus组中修复性牙本质桥的发生率为92.4%,氢氧化钙组为90%

J Endod:因龋牙髓暴露的有症状年轻恒牙使用Biodentine进行牙髓切断术的疗效观察

这篇前瞻性研究的目的是为了评估Biodentine (Septodont, Saint Maur des Fosses, France)用于因龋牙髓暴露的有症状年轻恒牙实施牙髓切断术的疗效。

J Endod:人恒牙部分牙髓切断术后牙髓对RetroMTA的反应

到目前为止,少有关于RetroMTA (BioMTA, Seoul, Korea)直接应用于活髓治疗后对牙髓影响的研究。这篇研究的目的是为了比较RetroMTA与ProRoot MTA (Dentsply Tulsa Dental, Tulsa, OK)应用于部分牙髓切断术的疗效。

J Endod:葡萄糖载体2和4在MTA牙髓切断术牙髓愈合过程中的作用

盖髓材料促进牙髓形成一薄层的修复性牙本质而使受损牙髓得以愈合。这一过程需要葡萄糖促使损伤区域愈合。葡萄糖通过葡萄糖载体(Glut) 2和Glut4转运,它们是一种跨膜蛋白,充当着守卫的作用。研究推测:葡萄糖通过Glut2/Glut4的转运可能有助于损伤后愈合过程中牙本质桥的形成。因此,这篇研究的目的是为了评估MTA盖髓后在修复性牙本质形成过程中Glut2和Glut4的表达情况。

J Endod:使用TheraCal进行部分牙髓切断术后牙髓的反应:一项临床试验

对于含树脂的充填材料如TheraCal直接作用于牙髓的效力一直存有疑问。这篇研究的目的是为了评估应用TheraCal进行部分牙髓切断术的临床效力,并与Biodentine和ProRoot MTA相比较。

J Endod:自体来源的骨髓间质干细胞对狗牙部分活髓切断术愈合能力的影响

牙髓切断术是因龋和外伤暴露特别是年轻恒牙的一种极其重要的治疗方法。对于部分牙髓切断术的牙齿来说,细胞疗法被认为是牙髓牙本质复合体再生的一种极具希望的方法。这篇研究的目的是为了评估自体来源的骨髓间质干细胞(BMSCs)对行牙髓切断术的狗牙模型愈合能力的影响。

J Endod:成熟恒牙牙髓切断术的长期疗效观察

成熟恒牙因龋暴露后实施的牙髓切断术能够保存剩余牙髓组织,但牙髓和修复的长期效果还未可知。这篇前瞻性研究的目的是为了检测牙髓和修复后牙齿的即刻及长期状态,并检验早期和晚期失败的牙齿在实施治疗时是无症状的还是仅有轻微症状时可能存在的潜在指征。
