Thus, the root of the second small and indigenous roots of the first and second molars, separated from the bottom of the maxillary sinus with a thin layer of bone. Sometimes the bottom of the maxillary sinus is bordered by a large indigenous roots of the third, and in front - with the roots of the first bicuspid and even canine.

    The roots of these teeth can stand in his bosom, and separated from its cavity only the periosteum and mucous membrane. Inflammatory processes in the tops of the roots of these teeth can spread to the mucosa of the maxillary sinus. Breakthrough of pus in the maxillary sinus is possible and with festering dental cysts of the upper jaw. Inflammation around the impacted teeth, as well as the remains of the roots of teeth can be a source of infection. Odontogenic sinusitis often develops as a result of perforation of the sinus floor during the removal of the tooth (called ruptured sinusitis).
