Alveolar fistula

Alveolar fistula

Alveolar fistula is one of the most common types of fistula. Its formation involves predominantly two adjacent teeth (rarely more).\n\nAlveolo-false articular fistulas are located in the transition zone between the mesial and distal walls of the vestibule of the oral cavity near the crown of the tooth, and also spread to the lateral or distal side. They do not exceed 5-7 mm in diameter, their contents contain leukocytes, desquamated epithelium with an admixture of microbes. They are often one-sided. Sometimes there are two or four, starting from one tooth. In alveolar-gingival fistulas, the cavity of the periodontal projection communicates with the cavity of the tooth through the alveolus and the canals of the third large molars, less often with the canals of the teeth of the same side, located on the upper jaw at an angle to the teeth.
