The diagnosis of dental sinusitis is established by the demonstration of the dynamic cause and effect relationship that inflamation of a tooth precedes the onset of maxillary sinusitis and the demonstration of the anatomical cause and effect relationship that the sinus floor forms a direct route with the cavity after tooth extraction. The apical focus is in contact with the sinus floor.The dynamic cause and effect relationship can be demonstrated by means of a detailed history, and the anatomical cause and effect relationship can be demonstrated by means of gross and X-ray examinations of teeth. In tooth examinations, there is a vertical percussion made in the perpendicular direction to the tooth axis that is most important. This examination reveals where the apical focus is located. Besides plane roentgenography, orthopantomography and oral roentgenography are essential for the observation of the relationship between the sinus floor and teeth and of apical foci.
