摘要: Placement of orifice plugs has been suggested to augment the seal conventional root canal fillings. This study assessed in vivo efficacy white mineral trioxide aggregate (MTA) preventing periapical inflammation subsequent coronal inoculation root-filled teeth. The two-rooted mandibular premolars six beagle dogs were conventionally prepared and filled with gutta-percha sealer. A MTA plug was placed into one each tooth. Pulp chambers inoculated plaque except for 12 teeth (negative control), restored. Radiographs taken at regular intervals. At 10 months, killed jaw blocks processed histology. None roots revealed radiographic or histologic evidence severe inflammation. Mild observed 17% 39% without an plug, respectively (McNemar, p > 0.05). Without development inflammation, augmentation could not be determined.
