背景:在牙科实践中,不同的情况需要蚀刻搪瓷层。酸蚀,目前的黄金标准,可以用其他方法代替,如激光蚀刻。我们的范围审查的主要重点是评估有关不同类型的激光的有效性的现有文献,为了确定到目前为止研究的主要方面,并了解哪里需要新的搜索策略。
方法:在几个数据库中进行了搜索,重点是激光蚀刻人类最终牙釉质。我们纳入了2000年1月至2021年12月之间发表的英语文章。
结果:回顾的34篇文章表明,硬激光器,呃:YAG,呃,Cr:YAG,可以代表在搪瓷表面上的替代蚀刻方法。他们创造了一个骨折,不规则的表面和开放的牙本质小管,非常适合粘附,但形成空腔的风险较低。Nd:YAG,CO2和二极管激光器无助于产生足够的剪切粘结强度。有,然而,证据表明,使用激光能量热机械消融后,釉质层中可能会出现微裂纹。
结论:虽然酸蚀仍成功用于牙釉质调理,手术后几天,一些研究人员强调了唾液在牙釉质再矿化过程中的作用。在这种情况下,可以使用激光能量,特别是在正畸治疗的情况下粘接陶瓷托槽。然而,因为热机械消融会产生微裂纹,需要进一步的研究,以建立明确的发现有关使用激光能量的搪瓷蚀刻。
BACKGROUND: In dental practice, different situations require etching the enamel layer. Acid etching, the present golden standard, may be replaced by other methods, such as laser etching. The main focus of our scoping review is to assess the existent literature regarding the effectiveness of different types of lasers, to identify the main aspects studied so far, and to understand where new search strategies are needed.
METHODS: The search was conducted in several databases focusing on the laser etching of human definitive enamel. We included English language articles published between January 2000 and December 2021.
RESULTS: The 34 articles reviewed showed that hard lasers, Er:YAG, Er,Cr:YAG, may represent an alternative etching method on enamel surfaces. They create a fractured, irregular surface and open dentin tubules, highly suitable for adhesion but with a lower risk of cavity formation. Nd:YAG, CO2, and Diode lasers do not help in creating sufficient shear bond strength. There is, however, evidence suggesting that microcracks in the enamel layer may appear after thermomechanical ablation using laser energy.
CONCLUSIONS: While the use of acid etching is still successfully used for enamel conditioning, some researchers have emphasized the role played by saliva in the enamel-remineralization process a few days after the procedure. In this context, laser energy can be used, especially for bonding ceramic brackets in the case of orthodontic treatments. However, as thermomechanical ablation can generate microcracks, further research is required in order to establish clear findings concerning the use of laser energy on enamel etching.
