摘要: 目的 探讨数字化平行投照根尖片和数字化口腔全景片在评价牙槽骨角形骨吸收方面的差异。方法 选取47名牙周病患者55个研究位点,术前同期拍摄数字化平行投照根尖片和数字化口腔全景片。对角型吸收牙周病患区的牙槽骨缺损宽度和高度进行测量,测量结果与临床手术测量值比较,结果进行方差分析。结果 无论是垂直向测量还是水平向测量,数字化平行投照根尖片的测量值与临床测量值的一致性都优于数字化口腔全景片。其中平行投照根尖片测量角形吸收垂直距离与临床手术测量结果的相似度最高。结论 数字化平行投照根尖片较数字化口腔全景片能更加精确地反映牙槽骨角形骨吸收的真实程度。

Abstract: Objective The aim of this article is to discuss the difference between digital parallel periapical radiograph and digital panoramic radiography in evaluating the angular resorption of alveolar. Methods By means of digital parallel periapical radiograph and digital panoramic radiography, 55 teeth points in 47 patients with periodontitis were evaluated bone resorption horizontally and vertically. Then compared with the method of clinical operation by analysis of variance .Results Whether measured horizontally or vertically, the result of digital parallel periapical radiograph is more similar as clinical operation than digital panoramic radiography. The results showed that the data of vertical distance of the angular resorption by means of digital parallel periapical radiographs the most similar to the results of the clinical operation. Conclusions The digitized parallel periapical radiograph can reflect the true extent of the angular resorption in the alveolar bone more accurately.

Key words: angular resorption, digital parallel periapical radiograph, digital panoramic radiography
