The fourth edition of this highly regarded manual provides information on current intraoral radiographic techniques and new material on radiation safety. Featured in this book are illustrated descriptions of techniques for taking periapical and bitewing films, including Precision Instrument and Stabe paralleling as well as bisecting-the-angle periapical techniques. Also described and illustrated are panoramic and cephalometric radiographic procedures and supplemental intraoral procedures such as occlusal radiography and third molar disto-oblique films. The basic principles of radiation biology and radiation safety presented here provide a scientific basis for safe and effective clinical radiography as well as the information needed to answer patients' questions about radiation effects and safety. An illustrated section on radiographic anatomy gives students the background necessary for assessing clinical film quality and correctly mounting radiographs. The authors discuss the composition of radiographic film and film processing procedures in order to enable students to effectively organize a dental darkroom and correctly process dental radiographs.The extensive use of illustrations throughout the manual adds significantly to the clarity of the material. "Dental Radiology" is intended for dental auxiliary students as well as practicing dental assistants and hygienists.
