The term "alveolar" refers to structures that resemble small cavities or pits, commonly found in the lungs and teeth. In the lungs, alveoli are tiny air sacs where the exchange of oxygen and carbon dioxide occurs during breathing. This process is essential for respiration and maintaining healthy blood oxygen levels. In dentistry, alveolar refers to the bony ridge in the jaw that contains the sockets for teeth. This alveolar bone supports the teeth and is crucial for oral health. Proper care of the alveolar structures is important to prevent issues like tooth loss and gum disease.
