Abstract:

Sinus tracts of odontogenic origin most commonly open into the oral cavity but occasionally may drain extraorally. The diagnosis is more difficult when necrosis of the tooth occurs in the absence of dental caries. We report a 23-year-old man with a long-standing chronic wound on the inferior aspect of the chin that was refractory to treatment. This case demonstrates the use of a simple technique to identify a necrotic mandibular incisor tooth as the source of infection.

Anatomy of Respiratory System I: Upper Respiratory Tract

Anatomy of Respiratory System I: Upper Respiratory Tract

The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.
