Acute Pain Rate of Single Versus Two-visit Root Canal Treatment of Teeth With Necrotic Pulps

Overview

Aim to compare acute pain rate after single-visit ortwo-visits treatment of teeth with necrotic pulp and apical periodontitis .90 teeth with a diagnosis of pulp necrosis and apical radiolucency at the apex.Working length was established with EAL and confirmed radiographically. Flex-R files were used to complete canal preparation. Level ofdiscomfort were recorded and cases with acute postoperative pain.

Detailed Description

90 teeth with a diagnosis of pulp necrosis and apical radiolucency at the apex.Working length was established with EAL and confirmed radiographically. M4system with Flex-R files were used to complete canal preparation. Level ofdiscomfort were recorded and cases with severe postoperative pain and/orswelling were classified as acute pain.

Interventions

  • Procedure: Ibuprofen for post operative pain
    • All treatment sessions were approximately 45 minutes in length to allow for acceptable time for completionof treatment and retreatment in one or two visits. Allthe clinical procedures were performed by the author.Following local anesthesia with 2% lidocaine with1:100,000 epinephrine (Septodont Saint-Maur desFossés, France) and rubber dam isolation the toothwas disinfected with 5.25% NaOCl (Ultra bleach,Bentonville, AR, USA).

Arms, Groups and Cohorts

  • Experimental: Post-endodontic Pain after a RCT
    • Ibuprofen for Post operative pain. Take 400 mg takena week after. Incidence of flare ups after a single vsmultiple visits root canal treatments.
  • Experimental: Acute pain
    • Acetaminophen 325 mg for Acute pain. Taken secondday after. Incidence of Post operative pain after rootcanal treatment in one vs two visits

Clinical Trial Outcome Measures

Primary Measures

  • Pain intensity measure with general pain scale
    • Time Frame: a week
    • Each patient will recall a week to evaluate post operative pain
