    Recently, advancement of the radiotherapeutic technologies for cancer treatment is striking and the clinical outcomes are greatly enhanced. More and more cancer patients are now receiving radiotherapy in Japan. In this situation, basic understanding of radiation oncology including radiobiology is essential especially for the JSOMFR-certified experts of dental radiology to realize recent radiotherapy for oral cancer. In this commentary, basics of radiobiology to understand the quantitative aspects of fractionated irradiation and characterization of some recent radiotherapeutic technologies will be described.

    Development of modern imaging techniques has significantly altered the treatment and management of oral and maxillofacial lesions. Important treatment decisions that were once made by intraoral and/or panoramic radiography are now made by using information from CT and MRI imaging. The intent of this article is to provide the specific information from CT findings that needs to clinicians manage patients with various diseases of jaw. Evaluation of the internal oblique line, anterior region of the Jaw, enhanced cystic wall, solid component, calcification, tumor margin, periosteal reaction, and posterior wall of the maxillary sinus, et al. are very important for CT image reading. Key CT images necessary for correct imaging diagnosis and what clinicians need to know and that will directly affect the diagnosis of lesions of the jaw are provided.

    General dentists in clinical dentistry need accurate diagnostic information from the radiographic investigations to plan dental treatment at the initial visit. Dental or panoramic images are used in the initial step for decide on the courses of treatment. Dental images mainly show the usefulness of paying a careful attention to detail under pathological condition, whereas the panoramic image provides clear information about the whole situation for pathological lesions in the oral-facial area.
    However, positioning of patient, radiographic condition, artifact, the directions of both rotational shooting and the shooting angle, and image interpretation in panoramic radiography all have a profound effect on diagnostic information obtained. When the radiologist is unclear in the interpretation and cannot provide a definite diagnosis, this presents a major challenge. Therefore, important points relating to interpretation of images are provided, in which radiologists consider the future strategy for dental and panoramic images. Our radiologists hope that readers will use this information and learn from the practical examples.
