Besides the statistics of its vigor of germination, the M1 root-tip cells of these broad beans were systematically analyzed on their changes in mitotic percentage, morphology and behavior of chromosomes, along with the structure o f cytoskeletons, including microtubule and intermediate filament. Based on all results of these studies, our opinions have been expressed in the report on the mechanism of low-energy N+ beams effecting on higher dicotyledons such as broad beau.展开更多
目的 探讨显微根尖手术结合iRoot BP Plus治疗难治性根尖周炎的效果。方法 选择苏州市华夏口腔医院2021年1月—2025年3月接诊的62例难治性根尖周炎患者,经随机数字表法分成观察组和MTA组,每组31例。两组行显微根尖手术。观察组采用iRoot...目的 探讨显微根尖手术结合iRoot BP Plus治疗难治性根尖周炎的效果。方法 选择苏州市华夏口腔医院2021年1月—2025年3月接诊的62例难治性根尖周炎患者,经随机数字表法分成观察组和MTA组,每组31例。两组行显微根尖手术。观察组采用iRoot BP Plus,MTA组采用矿物三氧化物凝聚体(MTA)修复材料填充。观察两组患者术前术后肿痛改善情况以及患者根尖周指数和牙周指数。结果 观察组术后肿胀评分[(0.95±0.18)分[与疼痛评分](0.93±0.12)分]均显著低于MTA组[(1.59±0.19)分、(1.63±0.23)分](P<0.05)。观察组术后旧根尖周指数水平[(1.26±0.23)]分均显著低于MTA组[(1.49±0.18)分](P<0.05)。观察组术后牙周指标水平显著优于MTA组(P<0.05)。结论 显微根尖手术基础上,采用iRoot BP Plus作为填充材料,可更好地改善患者术后肿胀症状,降低旧根尖周指数和牙周指标,治疗效果较好,应用效果可靠。展开更多
