Clinical Trial Summary

All patients will be treated in a single session approach regardless of the group. All molars will be anesthetized either through infiltration in case of maxillary molars or inferior alveolar nerve block in case of mandibular molars using Octocaine 2% with epinephrine 1: 100,000 (Lidocaine HCl, Novocol Pharmaceutical, Ontario, Canada.). Rubber dam will be applied; and access will be opened using Endo access bur.

In group A manual glide path will be established using manual thermal treated stainless-steel files in a watch winding maneuver. In group B glide path will be established using rotary Ni-Ti files in a reciprocating maneuver. Coronal flaring will be performed using Gates Glidden drill #3 in a brushing motion away from dangerous zone. Root canals will be copiously irrigated using 10 ml 2.5% sodium hypochlorite NaOCl (Clorox; Egyptian Company for household bleach, Egypt) delivered using 28 Gauge safety Steri Irrigation Tip (DiaDent Group International, Burnaby, BC, Canada) inserted 3 mm below cementoenamel junction. Working length will be determined using electronic apex locator Root ZX II (J. Morita Mfg. Corp, Kyoto, Japan) and confirmed radiographically using parallel technique with receptor holding device. Canals were irrigated again with 10ml 1.5% NaOCl, which was delivered 2mm coronal to apical canal terminus. Irrigation was hydro-dynamically agitated with EndoActivator device (Dentsply Maillefer, Baillagues, Switzerland) using blue tips #30/06 inserted 2mm short of working length for 60 seconds.

Root canals will be shaped using ProTaper next rotary Ni-Ti files (Dentsply Maillefer, Baillagues, Switzerland). Finally, Root canals will be obturated using cold lateral compaction technique. The molars will be permanently restored using composite resin restoration and will be scheduled for extra coronal restoration.
