In periodontitis, root surface alterations have been observed in the cementum due to the presence of toxic substances mainly endotoxins of various microorganisms. Elimination of endotoxins from diseased root surfaces by root planing and demineralisation procedures seem to be essential for new attachment procedures. In this study the effects of citric acid and tetracycline HCl on periodontally involved root surfaces which had been scaled and root planed were evaluated by scanning electron microscopy. Our results showed that scaled, root planed and citric acid treated surfaces were relatively even with many dentinal tubules. The planed and tetracycline HCl treated root surfaces, however showed an irregular cemental surface with some debris, whilst the control surfaces found to be irregular with a considerable amount of debris.
在牙周炎中，由于主要存在各种微生物的内毒素等有毒物质，牙骨质中已观察到根面改变。通过根面平整和脱矿程序从患病根面清除内毒素似乎对新附着程序至关重要。在本研究中，通过扫描电子显微镜评估了柠檬酸和盐酸四环素对已进行刮治和根面平整的牙周受累根面的影响。我们的结果表明，经过刮治、根面平整和柠檬酸处理的表面相对平整，有许多牙本质小管。然而，经过根面平整和盐酸四环素处理的根面显示出不规则的牙骨质表面并有一些碎屑，而对照表面则发现不规则且有大量碎屑。
