Objects of interest that are located outside the focal trough (it is the area of the dental anatomy that is reproduced distinctly on the panoramic radiograph) are not seen, and artifacts are commom and may easily be misterpreted. Nevertheless, this radiographic examination presents a lack of details and resolution of some structures due to overlapping of anatomical structures in the image, mild distortion and magnification. Individual structures may be imaged by other methods, once pathologic conditions have been detected using the panoramic radiography. It is an excellent projection of diverse structures on a single film, which no other imaging system can achieve. The panoramic radiograph is an excellent imaging modality in patients with trismus or trauma, because such patients cannot open their mouths and this is not needed to take a panoramic film.
Panoramic xray series#
The panoramic radiograph is less confusing to the patient than a series of small separate intraoral radiographs, making it easier for the dentist to explain the diagnosis and treatment plan to the patient. The dose to the patient is approximately ten times less than full-mouth survey using the long cone and E+ film and it is four times less than four bitewings using the long round cone and E+ film. Panoramic radiography has many advantages including short time for the procedure, greater patient acceptance and cooperation, overall coverage of the dental arches and associated structures (more anatomic structures can be viewed on a panoramic film than on a complete intraoral radiograph series), simplicity, low patient radiation dose. Advantages and disadvantages of panoramic radiography In dental clinical practice, panoramic radiography is one of the most indicated radiographic examinations by dentists because it provides a general overview of dentomaxilomandibular structures and it is not so costly for patients.ģ. Some contraindications of panoramic radiographs are clinical situations that require detail and definition, such as carious lesions, visualization of alveolar crests, level of root canal filling, periodontal disease or periapical lesions. If you have a full-mouth series, the panoramic radiography shows no more or little useful information for a patient receiving general dental care.
Panoramic xray professional#
The panoramic radiography is frequently used as initial diagnostic image of some alterations and based on it, the professional will verify the need of other more detailed and more accurate examinations.
The panoramic radiograph allows the dental professional to view a large area of the maxilla and mandible on a single film. It is frequently indicated when professionals want to evaluate some structures such as unerupted third molars, orthodontic treatment, tooth development, developmental abnormalities, trauma, large lesions, and others. Panoramic radiography is a radiologic technique that provides an overview of the jaws and surrounding structures. Indications and contraindications of panoramic radiographs
