The quality of secretory IgA was categorized in three degrees (+++, ++ and +) based on wideness of specific fluorescence.<br>Byimmunopathological observation' diffuse pattern, fiblillar or granular pattern were odserved. Degree of +++ showed highest frequency in the plaque from molar and lowest in incisor.<br>From the results, the following conclusins were obtained:<br>1) The levels of secretory IgA were related with an excretory passage of the parotid glands.<br>2) The levels of secretory IgA were also related with occurence area of the gingivitis.
