Study Notes
Dental Radiography
- Maxillary molars require the visibility of the entire crown and root, including the apex and surrounding structures.
- Anterior teeth require the visibility of the interproximal alveolar bone and mesial contact.
- Adjacent teeth require the visibility of contacts between them.
- Mandibular premolars require the visibility of the entire crown and root, including the apex and surrounding structures.
- Recommended size of receptors for anterior teeth is size 0 or 1.
- Recommended size of receptors for posterior teeth is size 2 or 3.
Technique Modifications
- When the lack of parallelism between the receptor and the long axis of the tooth exceeds 20 degrees, the technique modification necessary is to angle the receptor to match the tooth's long axis.
- For patients with a shallow palate, the modification in technique is to place the receptor more posteriorly to avoid discomfort.
Radiograph Visibility
- Maxillary canines require the visibility of the distal contact.
- Mandibular second premolars require the visibility of the distal contact.
- Mandibular incisors require the visibility of the entire crown and root, including the apex and surrounding structures.
Paralleling Technique
- The primary advantage of the paralleling technique is that it provides accurate and undistorted images.
- When using the paralleling technique with a patient who has a shallow palate, the receptor should be placed more posteriorly to avoid discomfort.
- For a maxillary torus, the correct placement of the receptor is more anteriorly and superiorly to the torus.
- To avoid impinging on muscle attachments and sensitive soft tissues in the floor of the mouth area, the receptor should be placed more superiorly.
