Root canal inside and outside the absorption of the processing

Root inside and outside the absorption of different reasons, the treatment and prognosis are not the same. Therefore, in accordance with the x-ray and clinical manifestations, the distinction between internal and external absorption to select the appropriate treatment.

Within the absorption from the medullary cavity or root canal wall, with pulpitis and bacterial infection. Generally do not have symptoms, mostly x-ray photography. As soon as possible root canal therapy, removal of infected tissue, the prognosis is good, or the further development will result in the perforation of the root canal wall.

Distinguish root inside and outside the absorption performance according to x-ray periapical films and bite-wing film. The absorbing boundary is clearly smooth, more symmetrical shape of the absorption parts of the root canal thick; outer absorbing boundary were rough with different density, was eroded shaped, multi-asymmetric shape, the destruction did not wear through the root canal wall. Can still find the original root canal outline. Offset projection, internal absorption and the root canal of the positional relationship unchanged; outer absorption site changes.

Completely removed within the absorptive parts of infected tissue is more difficult. The hypochlorite full flushing or ultrasound swing wash is effective cleaning methods and calcium hydroxide paste and then sealed in the root canal root canal. Absorbed in irregular, the best vertical compaction of warm gutta technical root canal. If the absorption is too large, the root canal wall is thin, and dental instruments should avoid excessive pressure, you should use oxygen to calcium oxide matrix paste and dental adhesive root filling. Root canal wall perforations smaller, the available calcium hydroxide paste the root charge 3 to induce hard tissue formation after root canal, or root filling with MTA root canal repair. The larger root wall perforation available MTA patch from the root canal or surgery. Within the absorption near-apical to apical surgery can consider more than one tooth may consider cutting the root of surgery.

Root outside the absorption from the periodontal tissues, mostly due to trauma, the correction is too large, impacted teeth, teeth bleaching, and then implant periapical inflammation. Approach due to periapical inflammation caused by apical absorption with absorbed, and other factors outside the absorption corresponding pipe handling and root treatment.
