目的:本研究的目的是评估三种不同药物对牙周受损牙齿的去污效果。
方法:本研究包括75颗因牙周病而拔除的磨牙。之后,使用简单随机技术将25个样本随机分配到三个不同的代理组,A组:缩放和根部平整(SRP)以及SofScale试剂的应用,B组:SRP和QMix剂的应用,C组:SRP和MTAD剂的应用。用金刚石圆锯,将处理的部分分成水平和垂直两半。在扫描电子显微镜下观察所有样品。每颗牙齿都集中在冠状第三颗,中间三分之一,和顶端第三部分,放大倍数为1000倍。记录数据并进行统计学分析。
结果:在根面,QMix剂(3.06±0.04)组,其次是MTAD剂(3.28±0.09)和SoftScale剂(4.14±0.10)组。在组内比较中,在所有三个水平的所有组内药物中,发现有统计学上的显着差异。关于群体间评价,在第三日冕,不同药物之间没有发现显著差异。在中部和冠状三分之一的不同药剂之间发现了显着差异。
结论:结论,目前的调查发现,与用MTAD和SofScale试剂处理的牙齿表面相比,用QMix处理的牙根表面显示出更强的去除涂抹层的能力。
结论:SRP等常规疗法可有效消除结石,牌匾,和坏死的牙骨质;尽管如此,它们会留下一层可能妨碍正常愈合的涂抹层。为了克服这一点,将根调理剂应用于根表面以去除涂抹层。传统的根系调理剂如柠檬酸有必定的缺点,虽然,例如可能损害根表面的酸性pH值。因此,研究人员一直在寻找更有效的生物相容性根部调理治疗方法。如何引用这篇文章:SinghDK,BSRajH,SoansCR,etal.三种不同药物对牙周损伤牙齿的涂抹层去除功效的评估:体外研究。JContempDentPract2024;25(2):156-159。
OBJECTIVE: The purpose of the present
study was to evaluate the smear layer removal efficacy of three various agents on periodontally compromised tooth.
METHODS: The current
study included 75 molar teeth that were extracted due to periodontal disease. After that, 25 samples were randomly assigned using a simple random technique to the three different agent groups, group A: Scaling and root planing (SRP) and application of SofScale agent, group B: SRP and application of QMix agent, group C: SRP and application of MTAD agent. Using a diamond circular saw, the treated portions were divided into horizontal and vertical halves. All samples were viewed under Scanning Electron Microscope. Every tooth was focused at the coronal third, middle third, and apical third portion with a magnification of 1000×. Data were recorded and statistically analyzed.
RESULTS: The smear layer removal efficacy was more in the QMix agent (3.06 ± 0.04) group followed by MTAD agent (3.28 ± 0.09) and SofScale agent (4.14 ± 0.10) group on the root surface. On intra group comparison, there was a statistically significant difference found in all the intra group agents with all the three levels. On inter group evaluation, at coronal third, there was no significant difference found between the different agents. There was a significant difference found between the different agents at middle and coronal third.
CONCLUSIONS: On conclusion, the current investigation found that, the root surfaces treated with QMix shown a greater ability to remove smear layers compared to tooth surfaces treated with MTAD and SofScale agent.
CONCLUSIONS: Conventional therapies such as SRP effectively eliminate calculus, plaque, and necrosed cementum; nevertheless, they leave behind a smear layer that could impede normal healing. In an effort to overcome this, root conditioning agents were applied on the root surface to remove the smear layer. The traditional root conditioning agents such as citric acid have certain disadvantages, though, such as an acidic pH that could harm the root surface. As a result, researchers have been looking for biocompatible root conditioning treatments that are more effective. How to cite this article: Singh DK, BS Raj H, Soans CR, et al.
