In which lung lobe is it most likely for a tooth that has been aspirated to end up?

• A. Left upper lobe
• B. Right lower lobe
• C. Right upper lobe
• D. Left lower lobe

Answer: (B)

When a tooth is aspirated, its path through the bronchial tree is significantly influenced by the anatomy of the tracheobronchial system. The right main bronchus is wider, shorter, and more vertically oriented compared to the left. This anatomical configuration often allows aspirated objects, including teeth, to be more likely trapped in the right lung rather than the left. Within the right lung, the lower lobe is anatomically positioned to receive aspirated objects more frequently. The bronchial branches leading to the right lower lobe are situated in direct alignment with the trachea, making it the most probable destination for aspirated items. In summary, the anatomical characteristics of the right main bronchus and the configuration of the bronchial tree result in a higher likelihood of aspirated objects, such as a tooth, ending up in the right lower lobe, supporting the choice of that answer.
