Abstract

Background: Supragingival polishing is a crucial part of nonsurgical periodontal therapy. In recent years, air polishing has been used for this purpose, introducing different polishing powders. The purpose of the following study was to investigate the damage to the gingival margin during air polishing by an inexperienced operator.

Methods: Five porcine models were polished by means of three different polishing powders: calcium carbonate, sodium bicarbonate, and erythritol. Their impact on the gingival margin was examined by means of histological and scanning electron microscopical observations and compared to healthy samples and samples polished with a polishing brush and paste.

Results: The histological observations revealed superficial to minor lesions limited in the epithelium by all the groups tested. Both examination protocols demonstrated less invasiveness of the erythritol-based polishing powder.

Conclusions: Within the limitations of the present study, it could be concluded that air polishing is a safe instrumentation method for periodontal therapy even in inexperienced hands when the exact protocol is followed. The erythritol-based polishing powder seems to provide less of an impact on the gingival margin.

无经验操作者对龈上抛光过程中龈缘损伤的初步研究。

背景：龈上抛光是牙周非手术治疗的重要组成部分。近年来，空气抛光已用于此目的，引入了不同的抛光粉。以下研究的目的是调查在空气抛光过程中由一个没有经验的操作员对牙龈边缘的损害。方法：用碳酸钙、碳酸氢钠和赤藓糖醇三种不同的抛光粉对5只猪模型进行抛光。通过组织学和扫描电镜观察检查其对牙龈边缘的影响，并与健康样品和用抛光刷和膏抛光的样品进行比较。结果：组织学观察显示，所有测试组均局限于上皮的浅表至轻微病变。两种检查方案均显示赤藓糖醇基抛光粉的侵入性较小。结论：在本研究的限制范围内，可以得出结论，空气抛光是一种安全的牙周治疗仪器方法，即使是在没有经验的手，当严格遵守协议。以赤藓糖醇为基础的抛光粉似乎对牙龈边缘的影响较小。

期刊介绍： Journal of Functional Biomaterials (JFB, ISSN 2079-4983) is an international and interdisciplinary scientific journal that publishes regular research papers (articles), reviews and short communications about applications of materials for biomedical use. JFB covers subjects from chemistry, pharmacy, biology, physics over to engineering. The journal focuses on the preparation, performance and use of functional biomaterials in biomedical devices and their behaviour in physiological environments. Our aim is to encourage scientists to publish their results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Several topical special issues will be published. Scope: adhesion, adsorption, biocompatibility, biohybrid materials, bio-inert materials, biomaterials, biomedical devices, biomimetic materials, bone repair, cardiovascular devices, ceramics, composite materials, dental implants, dental materials, drug delivery systems, functional biopolymers, glasses, hyper branched polymers, molecularly imprinted polymers (MIPs), nanomedicine, nanoparticles, nanotechnology, natural materials, self-assembly smart materials, stimuli responsive materials, surface modification, tissue devices, tissue engineering, tissue-derived materials, urological devices.
