Influence of Apical Patency Concept Upon Postoperative Pain After Root

Status Completed

Clinical Trial Summary

The aim of this clinical study is to evaluate the influence of apical patency concept implementation upon postoperative pain following root canal treatment in a single visit approach in molars with pulpal disease.

Clinical Trial Description

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. Canals will be scouted using manual patency file in a watch winding maneuver and then 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 will be irrigated again with 10ml 1.5% NaOCl, which will be delivered 2mm coronal to apical canal terminus. Irrigation will be hydro-dynamically agitated with EndoActivator device (Dentsply Maillefer, Baillagues, Switzerland) using yellow tips #20/06 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). In Gp A, apical patency will be maintained till obturation using electronic apex locator confirmed radiographically while in Gp B apical patency will not be maintained. 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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
