Tooth Decay and Respiratory Health Connection - Medical Diagram #2365646 (License: Personal Use)

The image presents a composite medical illustration: top-left shows a smiling face with healthy teeth; top-right and middle depict cross-sections of a tooth progressing from early enamel demineralization to deep pulp infection with surrounding bone loss; bottom illustrates the human respiratory tract, including trachea, bronchi, and lungs (one healthy, one with pathological changes). The layout emphasizes how untreated dental infections may contribute to aspiration or systemic inflammation affecting respiration.

Used on dental or medical educational pages discussing oral-systemic health links, particularly in articles about periodontal disease and respiratory infections like pneumonia or COPD. Targets patients, students, and clinicians seeking visual explanations of interdisciplinary health risks.
