Abstract

The purpose of this study was to determine the presence of certain inorganic elements in various cementum surfaces. The electron probe analysis appears to be the most suitable technique for examining elemental composition within localized small areas of mineralized tissue, it was used to determine the mineral contents of nondiseased, periodontally diseased and root planing applied diseased cementum surfaces were determined by electron probe. Calcium (Ca) and phosphorus (P) were the elements searched for. Surface morphological features of these cementum surfaces were also examined. Electron probe analysis indicated an elevated Ca and P content in diseased cementum surfaces. Root planing of these surfaces did not reduce the mineral contents of these root surfaces. Our findings indicate that on the cementum surfaces affected by periodontal disease inorganic contents were altered and the hypermineralized layer in diseased cementum may play a role in preventing total diseased cementum removal by root planing.

牙骨质表面的电子探针分析。
本研究的目的是确定某些无机元素在各种牙骨质表面的存在。电子探针分析似乎是检查局部小区域矿化组织内元素组成的最合适的技术,它被用于确定未患病,牙周疾病和根刨应用病变牙骨质表面的矿物质含量。寻找的元素是钙(Ca)和磷(P)。这些牙骨质表面的表面形态特征也进行了检查。电子探针分析显示病变骨质表面钙、磷含量升高。刨根并没有减少这些根表面的矿物质含量。我们的研究结果表明,受牙周病影响的牙骨质表面的无机含量发生了改变,病变牙骨质中的高矿化层可能在阻止牙根刨除全部病变牙骨质中起作用。
