Radiographic examinations are essential in dental practice for accurate diagnosis, treatment planning, and monitoring of dental health. When deciding whether to perform radiographic imaging, a dental operator considers several crucial factors. Firstly, the clinical indications must justify the need for imaging. This includes evaluating the patient's oral health status, presenting symptoms, and specific diagnostic requirements that cannot be addressed through visual examination alone. Secondly, the patient's overall health and history are reviewed to assess potential risks associated with radiation exposure. The principle of ALARA (As Low As Reasonably Achievable) guides clinicians to minimize radiation dose while maximizing diagnostic yield. Thirdly, the age and physiological status of the patient influence the decision; for example, pediatric patients require careful consideration due to their increased sensitivity to radiation. Additionally, cost, patient compliance, and previous imaging results are considered to determine if new images are necessary.

Artifacts pose a significant challenge in obtaining clear and accurate dental radiographs. These are foreign objects or distortions superimposed over the image, leading to misinterpretation. Examples include jewelry, clothing, or dental appliances such as braces that can appear as artifacts. To prevent artifacts, clinicians should ensure proper equipment maintenance, use of appropriate film holders, and meticulous patient preparation. Patients should be instructed to remove any metallic objects from the head and neck area before exposure. Proper positioning and technique also help avoid artifacts such as blurring or distortion caused by movement. Regular inspection and calibration of radiographic equipment further reduce chances of technical artifacts. Education of the dental team on the importance of artifact prevention enhances the clarity and diagnostic value of radiographic images.

A bitewing film is a specific type of intraoral radiograph that captures the crowns of both the maxillary and mandibular teeth simultaneously. It is used primarily to detect dental caries between teeth, assess the crestal bone following periodontal disease, and evaluate restorations for integrity. During the procedure, the film is placed intraorally between the upper and lower teeth, with a bite block to stabilize position, and the patient bites down to hold the film securely. The X-ray tube is directed horizontally to capture the interproximal areas efficiently. Bitewing radiographs are particularly useful in detecting early caries not visible clinically, monitoring the progression of periodontal disease, and checking the fit of dental restorations. They are an integral part of routine dental examinations, especially for patients at risk of decay or periodontal issues.

The three types of intraoral X-rays include periapical, bitewing, and occlusal radiographs. Periapical radiographs focus on a few teeth, capturing the entire tooth from crown to root tip and the surrounding alveolar bone. They are used to diagnose root infections, fractures, and bone pathology. Bitewing radiographs, as mentioned earlier, are used to examine interproximal surfaces. Occlusal radiographs are larger films used to visualize a broader area of the jaw or palate, providing information about the maxilla or mandible, developmental anomalies, or cysts. They are useful in examining larger areas of the jaw that are difficult to capture with periapical or bitewing films, such as impacted teeth or pathologies involving the floor of the mouth or maxillary sinuses.

The two basic techniques for achieving relevant intraoral radiographic images are the paralleling technique and the bisecting angle technique. The paralleling technique involves positioning the film parallel to the long axis of the tooth, with the x-ray beam directed perpendicular to the film and the tooth. This method produces minimal distortion and is considered the most accurate. The bisecting angle technique involves angling the film so that the plane of the film bisects the angle formed between the long axis of the tooth and the beam. This technique is useful when the patient's mouth size restricts parallel positioning but can lead to increased distortion if not performed correctly. Proper knowledge and application of these techniques ensure high-quality images that aid in accurate diagnosis.

Digital imaging in dentistry can be produced in three prominent ways: direct digital radiography, indirect digital radiography, and phosphor plate systems. Direct digital radiography involves sensors connected directly to a computer that capture images rapidly upon exposure. It provides immediate images, reduces radiation dose, and simplifies image management. Indirect digital radiography uses a phosphor storage plate that, after exposure, is processed in a reader to generate a digital image. This method is similar to traditional film but offers digital advantages, such as image enhancement and storage. The phosphor plate system combines the benefits of digital imaging with familiar handling, allowing for flexible positioning and reduced patient discomfort. Each method varies in workflow, cost, and image quality, but all improve diagnostic efficiency compared to conventional film-based techniques.
