NCT01167985

Brief Summary

The effect of Antibacterial Nanoparticles, Incorporated in root canal sealer material and in provisional restoration is going to be examined. Two different tests are planned: (1) clinical and radiological evaluation of root canal sealer.(2) An evaluation in the laboratory the efficacy of provisional restoration during root canal treatment.We assume, based on our previous laboratory studies that show antibacterial properties, that the incorporation of the nanoparticels will improve the treatment outcome.

Outcome Measures

Primary Outcomes (1)

  • In vitro evaluation

    clinical and radiological evaluation of the radiolucent periapical lesion, for the root canal sealer. As for the provisional restoration, in vitro assesment of bacterial growth.

    One month for provisional restoration.

Secondary Outcomes (2)

  • Radiological evaluation of the root canal sealer

    1 year for the root canal sealer.

  • Clinical and in vitro evaluation of the root canal sealer

    1 year for the root canal sealer.

Interventions

IABNDEVICE

Patients with single canal teeth diagnosed with infected pulp and periapical lesion, and need root canal treatment, will be asked to participate in the study. The study group will have their canal sealed with endodontic sealer + the nanoparticles. The control group will have their canal sealed with the conventional sealer alone. The patients will be invited to 4 follow ups during which a clinical and radiological examinations will be performed.While preparing the post, a sample of the sealer will be taken to evaluation in the lab.
