Radiographic techniques, traditional ones as well as newer ones under development, for clinically assessing alveolar bone are critically assessed. Traditional intraoral radiography is reexamined, in particular with regard to the accuracy with which the alveolar crest is seen. Evidence is presented for a more accurate representation of the alveolar crest on bitewings rather than periapical films. Application in periodontics of newer radiographic techniques, subtraction radiography, and single and dual photon aborptiometry presently under clinical development are discussed in regard to their potential and limitations. Similarly, radiopharmaceuticals to evaluate the metabolic status of alveolar bone are discussed as well as the potential for using analyses of gingival crevice fluid as a window for assessment of alveolar crest metabolism.
对用于临床评估牙槽骨的放射技术，包括传统技术以及正在研发的新技术进行了严格评估。重新审视了传统口腔内放射摄影，特别是关于牙槽嵴显示的准确性。有证据表明，咬合翼片比根尖片能更准确地显示牙槽嵴。讨论了目前正在临床开发中的较新放射技术、减影放射摄影以及单光子和双光子吸收测定法在牙周病学中的应用及其潜力和局限性。同样，还讨论了用于评估牙槽骨代谢状态的放射性药物，以及将龈沟液分析用作评估牙槽嵴代谢窗口的可能性。
