This study compared the finishes on dental porcelain polished with four different polishing paste systems with oven reglazing and with a porcelain adjustment kit without a polishing paste. The polished/reglazed samples were rated according to quality of finish by independent observers and by scanning electron microscopy. On the basis of visual examination, two of the polishing paste systems tested were found to produce a surface equal to or better than oven glazing. On the basis of SEM examination, oven glazing was found to produce a better surface than the other polishing methods. Not all porcelain polishing systems produce a surface comparable to oven-glazed porcelain, and porcelain polishing systems should be chosen carefully.
本研究比较了使用四种不同抛光膏系统进行抛光、经烤炉重熔以及使用无抛光膏的瓷调整套件处理后的牙科烤瓷表面。由独立观察者根据表面光洁度质量以及通过扫描电子显微镜对抛光/重熔后的样本进行评级。基于目视检查，发现所测试的两种抛光膏系统产生的表面与烤炉上釉相当或更好。基于扫描电子显微镜检查，发现烤炉上釉产生的表面比其他抛光方法更好。并非所有烤瓷抛光系统都能产生与烤炉上釉烤瓷相当的表面，因此应谨慎选择烤瓷抛光系统。
