bitewing radiography Flashcards
Describe the rationale for dental radiography and its use in dental examination and diagnosis
The bitewing radiograph yused radiograph in general dental.The primary use radiograph is to detect dental caries that cannot be visualized clinically (i.e., with the eyes)
useful for assessing the integrity of dental restorations and does give us some evidence of early alveolar crestal bone loss, which is a manifestation of periodontal disease.

Narrower bite wing film is beneficial as it is well suited to radiographing the crowns in posterior teeth

Buccal objects rule
(SLOB)
Slob= same lingual opposite buccal
SLOB
he SLOB (Same-Lingual Opposite-Buccal) rule is a principle used in dental radiography to distinguish between two-dimensional objects in a radiograph. It helps determine the buccolingual (side-to-side) relationship of structures. By taking two radiographs from different angles, the clinician can determine whether an object is located buccally (toward the cheek) or lingually (toward the tongue) based on its movement relative to another object in the image. This rule is particularly useful for identifying the location of foreign objects, impacted teeth, or lesions within the oral cavity.
Bone loss detection
Bone loss detection in dental radiography refers to identifying signs of periodontal disease, which involves the loss of bone around the teeth due to bacterial infection and inflammation of the gums. Bone loss appears as a reduction in the height and density of the alveolar bone supporting the teeth on the radiographic image.
Caries detection
Caries detection on dental radiographs involves identifying areas of tooth decay or cavities. Carious lesions appear as radiolucent (dark) areas on the radiograph, typically in the enamel or dentin of the tooth.
Lesion and disease category
n the context of dental radiography, lesion and disease categories refer to the various types of abnormalities or pathologies that can be identified on radiographic images. This includes categories such as dental caries (cavities), periodontal diseases (gum diseases), periapical lesions (around the tooth apex), cysts, tumors, and developmental anomalies.
