In radiography, RBL refers to Radiographic Bone Loss. It is a measure of bone loss assessed through radiographic imaging.
Understanding Radiographic Bone Loss (RBL)
Radiographic bone loss (RBL) is an important indicator in assessing various conditions, particularly in dentistry and related fields. The provided reference focuses on the assessment of RBL using a deep learning (DL) model. Here's a breakdown:
-
Definition: RBL is the measurement of bone loss observed on radiographs (X-rays).
-
Calculation (according to the reference):
The RBL percentage is calculated using the following formula:
RBL % = (Distance between bone level and the lowest point of the clinical root) / (Distance between the CEJ level and the lowest point of the clinical root).
Where:
- CEJ: Cementoenamel Junction (the point where the enamel of the crown meets the cementum of the root).
Importance of RBL in Radiography
Radiographic bone loss is crucial for:
- Diagnosing periodontal disease.
- Evaluating the progression of bone loss over time.
- Assessing the effectiveness of treatments.
- Identifying other bone-related pathologies.
