No results posted yet for this study

Summary

The study aims to evaluate the efficiency of using a Calcium silicate-based sealer (CSBS) with different obturation techniques in treating root canals with apical periodontitis in single visit.

Evaluating:

1. Postoperative healing.
2. Preoperative, postoperative pain and frequency of analgesic intake.

Conditions

  • Periapical Periodontitis
  • Chronic Periapical Periodontitis
  • Periapical Abscess
  • Pulp Necrosis, Apical Periodontitis
  • Pulp Necrosis

Interventions

DEVICE

Dia-Root Bio Sealer

The sealer will be delivered in the canals with the provided intracanal tips inserted three millimeters from the WL and back filling until the orifice. The pre-fitted master cone will be inserted with slight up and down motion before reaching the WL.

PROCEDURE

Single cone (SC) Obturation technique

Filling the prepared root canal with the master cone and the CSBS. Then cutting the excess gutta percha from the root canal orifice

PROCEDURE

Warm Vertical compaction (WVC) technique

After placing the CSBS intside the RC, the cone will be packed down till 4 mm from the apex for 4 seconds cycles. Then the apical GP will be condensed using pluggers previously fitted inside the canal. Canals will be backfilled with 180C temperature setting. The tip will be placed into the root canal against the apical gutta-percha for 5 s before extruding the gutta-percha on increments. The middle and coronal thirds will be condensed using pre-fitted pluggers.

PROCEDURE

Cold lateral condensation (CLC) technique

After placing the CSBS inside the root canal, the master GP cone will be laterally condensed with a pre-selected spreader inserted 2-4 mm from the WL and accessory GP cone will be placed in the provided space by the spreader. This process will be repeated until 1 mm from the canal orifice. Excess GP will be cut at the orifice with a heat carrier and lightly packed vertically with a plugger.
