The concentration of secretory IgA in fluids present in the canals of 33 teeth was determined by the rocket immunoelectrophoresis technique. Except for the presence or absence of communication between the oral cavity and the root canals of the affected teeth, no other clinical finding showed significant statistical correlation with the presence of secretory IgA. The canals which were open to the oral flora had significantly higher concentrations of secretory IgA. Leaving canals open to the oral cavity may result in formation of periapical cysts.
采用火箭免疫电泳技术测定了33颗牙齿根管内液体中分泌型IgA的浓度。除患牙口腔与根管之间是否存在连通外，没有其他临床发现与分泌型IgA的存在有显著的统计学相关性。与口腔菌群相通的根管中分泌型IgA的浓度显著更高。使根管与口腔相通可能会导致根尖囊肿的形成。
