The results of this study are similar to other studies that have concluded that no material can completely seal the root canal and that no obturation technique completely avoids the microfiltration of microorganisms to the periapex.
The consequences of the loss of coronal seal are well established: a communication is established between the oral cavity and the periapex or periodontium through a lateral canal or the apical foramen [1].
The soft tissue removed from the periapex was sent for histological evaluation.
The systems with a 90A alternative and sym- metric movement require a large instrumental sequence whereas the systems limited to a 30A movement have a restricted cutting capacity and a tendency to extrude dentine and pulp debris towards the periapex.
Induced hypoxia in rat pulp and periapex demonstrated by 3H-misonidazole retention.
If the disease progresses, bacteria and their degradation products reach the periapex, becoming a periapical pathology; if this process progresses, there is a balance with the host's defenses, establishing chronic forms of purulent apical periodontitis, including the granulomatous form.
Radiolucent circumscribed area located on the periapex of dental organ 11
The microbial invaders in the root canal can advance, or their products can egress, into the periapex.
It has been reported that intrusive movements are a risk factor for root resorption, since stress forces concentrate in the radicular periapex.
t 45, 46 & 36 showed a large diffuse radiolucency involving apex, periapex & furcation area of 35,36,37 (Figure 3) and 44, 45, 46 (Figure 4).
For CH to achieve the aforementioned effects, it must have a high degree of diffusion to the periapex and the dentin's outer layer by penetrating through the dentinal tubules--something that is improbable due to the high reactivity of the OHions, the dentine buffer system, and its high surface tension.
An IOPA radiograph was advised which revealed a unilocular scalloped radiolucency at the periapex of 46 and 47.
