Abstract

Objectives: The aims of this retrospective study were to objectively assess bone density values obtained by cone-beam computed tomography and to map the periapical and inter-radicular regions of the mandibular bone.

Material and methods: In total, periapical bone regions of 6898 roots scanned by cone-beam computed tomography were evaluated retrospectively, and the results were recorded using Hounsfield units (HU).

Results: The correlation between periapical HU values of adjacent mandibular teeth were strongly positive (P ˂ 0.01). The anterior region of the mandible yielded highest mean HU value (633.55). The mean periapical HU value of the premolar region (470.58) was higher than that was measured for molar region (374.58). The difference between furcation HU values of the first and second molars was unnoticeable.

Conclusions: The results of this study have tried to evaluate the periapical regions of all mandibular teeth, which could ease to predict the bone radiodensity before implant surgery. Even though the Hounsfield units provide the average radio-bone density, a site-specific bone tissue evaluation of each case is essential for appropriate cone-beam computed tomography preoperative planning.

三维锥形束计算机断层扫描评估下颌骨根尖周骨的放射密度。

目的:本回顾性研究的目的是客观地评估通过锥形束计算机断层扫描获得的骨密度值，并绘制下颌骨的根尖周和根间区域。材料和方法:回顾性评价6898根经锥形束计算机断层扫描的根尖周骨区域，并使用Hounsfield单元(HU)记录结果。结果:牙周HU值与邻牙牙周HU值呈显著正相关(P小于0.01)。下颌骨前区平均HU值最高(633.55)。前磨牙区平均根尖周HU值(470.58)高于磨牙区(374.58)。第一磨牙和第二磨牙分岔HU值差异不明显。结论:本研究对所有下颌牙的根尖周区域进行了评估，有助于预测种植术前的骨密度。尽管Hounsfield单元提供了平均放射骨密度，但对于每个病例的特定部位骨组织评估对于适当的锥形束计算机断层扫描术前计划是必不可少的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
