目的探讨无牙颌口内数字化X线摄影（DR）图像灰度密度测量值的转换价值。方法对18例男性和34例女性无牙颌患者进行根尖周平片检查。将42个上颌和61个下颌感兴趣区（ROI）的骨小梁模式分为5个等级。在根尖周数字X线片图像中的ROI标记区域内，在相同的相应小梁区域内进行灰度密度测量。为了获得转换值，包括年龄、性别和颌骨区域的影响，期刊文章使用口内数字图像将小梁骨模式值的常规放射线检查数据转换为密度测量值Journal Oral Radiology Publisher Springer Japan ISSN 0911-6028（打印）1613-9674（在线）Issue Volume 25，Number 2 / December，2009分类原始文章DOI 10. 1007/s11282-009-0024-y
Objectives To determine the conversion value of grayscale density measurements from intraoral conventional radiographic examinations of the edentulous maxilla and mandible using intraoral digital radiography. Methods Periapical radiography examinations with a pararelling technique, both conventional and digital, were performed on 18 male and 34 female patients with edentulous maxillas and mandibles. The trabecular bone pattern of 42 maxillary and 61 mandibular regions of interest (ROIs) was classified into five grades. Grayscale density measurements were made within a marked area of the ROI in the image of the periapical digital radiograph in the same corresponding trabecular region. To obtain conversion values, including the effects of age, gender, and region of the jaw, Journal Article Converting conventional radiographic examination data of trabecular bone pattern values into density measurement values using intraoral digital images Journal Oral Radiology Publisher Springer Japan ISSN 0911-6028 (Print) 1613-9674 (Online) Issue Volume 25, Number 2 / December, 2009 Category Original Article DOI 10.1007/s11282-009-0024-y
