评价BS镍钛系统维持根管解剖原始形态的能力。方法 将20个离体牙根按照随机数表法分为两组(n=10),分别用BS蓝色小旋风(BS组)和WaveOne (WO组)以逐步深入法预备根管。预备后用Micro-CT对各牙进行扫描,Mimics软件测量其近远中根管壁的厚度,计算距根尖 1 mm、3 mm、5 mm、7 mm、9 mm处根管偏移量。
We investigated three-dimensional decrease in the volume of the pulp chamber caused by age-related secondary dentin formation using micro-CT and evaluated the applicability of the results to evaluati...
This study aimed to evaluate a commercial micro-CT system (μCT 20) for quantitative analysis of mineral concentration in human enamel and dentin using different methodologies, and thereby compare the ...
Objective: To investigate the precise longitudinal change in the periodontal ligament (PDL) space width and three-dimensional tooth movement with continuous-force magnitudes in living rats. Materia...
Objective: To establish a protocol for assessing orthodontically induced tooth root resorption (OITRR) in human premolars using micro-computed tomography. Materials and Methods: Ten extracted maxil...
The aim of this study is to elucidate the root resorption of primary incisors in relation to the development of permanent incisors. We observed the maxillas of the dry skulls of Indian children, using...
The purpose of this study was clarify the morphological condition of occlusal grooves in the maxillary first and second deciduous molars with micro-CT. We took photographs of the maxillary deciduous m...
2008年8月5日,中科院先进技术研究院在深圳组织会议,对中科院深圳先进院中科院生物医学信息与健康工程学重点实验室的中国科学院重大装备项目“用于昆虫/小动物微观结构及仿生学研究的显微CT研发”进行可行性论证。 天津大学姚建铨院士、中山大学陈仲本教授、东南大学万遂人教授、清华大学叶大田教授、哈工大张钦宇教授、中科院计财局装备处吕连清、深圳先进院张元亭教授等作为项目答辩专家组成员出席了会议。先...
This study establishes a new measurement method for quantification of mouse gutter shaped root (GSR). To evaluate GSR, we made clear the completion period of root formation by continuous observation f...
We report the newly developed Micro-CT, which allows us to observe the individual animal over a long experimental period and to compare changes in pulp tissue in relation to growth and aging without c...
In general, pulpotomy is evaluated by pathological examination of sacrificed animals at each observing stage. Not only lots of small animals have to devote itself to experimentation, but also the resu...
The purpose of the present study was to evaluate stress distribution by finite element analysis in an accurate model simulating trabecular bone using micro-CT. Dentulous and edentulous maxillary jaws ...
