What is overlapping in radiology dental?

In dentistry, overlapping refers to the partial or complete superimposition of two teeth or structures on the same dental or panoramic x-ray image. This can occur due to their positioning within the oral cavity, making it difficult to distinguish the individual anatomy of each tooth. Overlapping can create challenges in detecting pathologies, such as caries or cracks, as well as assessing root morphology and interdental spaces. To address this issue, additional imaging modalities like bitewings, periapicals, or 3D scans may be necessary for a comprehensive diagnosis and treatment planning.
