This is an in vitro study to investigate the effects of ultrasonic scaling on the surface roughness and quantitative bacterial count on four different types of commonly used composite restorative materials for class V cavities.
MATERIALS & METHODS: Nanofilled, hybrid, silorane and flowable composites were tested. Forty extracted teeth served as specimen and were divided into 4 groups of 10 specimens, with each group receiving a different treatment and were examined by a Field emission scanning electron microscope. Bacterial suspension was then added to the pellicle-coated specimens, and then bacterial adhesion was analyzed by using image analyzing program.
Flowable and silorane-based composites showed considerably smoother surfaces and lesser bacterial count in comparison to other types, proving that bacterial adhesion is directly proportional to surface roughness.
The use of ultrasonic scalers affects the surfaces of composite restorative materials. Routine periodontal scaling should be carried out very carefully, and polishing of the scaled surfaces may overcome the alterations in roughness, thus preventing secondary caries, surface staining, plaque accumulation and subsequent periodontal inflammation.

这是一项体外研究，旨在调查超声洁治对五类洞常用的四种不同类型复合树脂修复材料的表面粗糙度和细菌定量计数的影响。
测试了纳米填料、混合、硅烷和流动复合树脂。40颗离体牙作为标本，分为4组，每组10个标本，每组接受不同的处理，并通过场发射扫描电子显微镜检查。然后将细菌悬液添加到涂有薄膜的标本上，并用图像分析程序分析细菌黏附情况。
与其他类型相比，流动复合树脂和硅烷类复合树脂表面更光滑，细菌数量更少，证明细菌黏附与表面粗糙度成正比。
使用超声洁治器会影响复合树脂修复材料的表面。常规牙周洁治应非常小心进行，对洁治后的表面进行抛光可能会克服粗糙度的改变，从而预防继发龋、表面染色、菌斑积聚和随后的牙周炎症。如何引用本文：Eid H A, Togoo R A, Saleh A A, Sumanth C R.超声洁治后复合树脂修复材料的表面形貌及其对细菌菌斑积聚的影响。一项体外扫描电镜研究。《国际口腔健康杂志》2013年；5(3):13 - 19。
