Abstract

There are three main types of intraoral radiographs, i.e. Intraoral periapical radiograph, Bitewing radiograph and Occlusal radiograph. The anatomic area of interest and the type of pathology suspected helps the clinician to decide the type of radiograph to be taken. The intraoral periapical radiography (IOPA) is the basic investigation that gives graphic information about the alveolar bone, periodontal areas and the hard tissues of the tooth. The mastering of the technique, for making good IOPA radiographs is essential for the dental surgeon, both for routine and specialist work. Two intraoral projection techniques perhaps used for periapical radiography: (i) Paralleling cone and (ii) Bisecting angle. Good knowledge of the anatomy will guide the radio­grapher to modify the techniques to an individualized mode of X-ray visualization. Svenson B et al (1996) had recommended use of E-speed film and rectangular collimation as means of reducing the radiation dose in practice. They strongly recommend that continuing dental education programs are a must to sensitize the dental practitioners to the latest information on radiation protection.
