Effect of Lidocaine/Dexamethasone on the Success of IANB
- Registration Number
- NCT03531970
- Lead Sponsor
- Isfahan University of Medical Sciences
- Brief Summary
The purpose of this prospective, randomized, double-blind study was to compare the success rate of IAN block injection carried out with two cartridges of 2% lidocaine with 1:80000 epinephrine each combined with 0.2 ml dexamethasone versus two cartridges of 2% lidocaine with 1:80000 epinephrine each combined with 0.2 ml sterile distilled water for endodontic treatment of mandibular molars with symptomatic irreversible pulpitis.
- Detailed Description
Several investigations have been carried out to demonstrate the effect of dexamethasone added to local anesthetics in regional block injections. These investigations shown that the addition of dexamethasone to local anaesthetics may prolong the duration of anesthesia and also results in a faster onset. It is hypothesized that dexamethasone added to lidocaine may affect the success rate of inferior alveolar nerve block

- Primary Outcome Measures
Name Time Method success of IAN Block anesthesia for the Dexamethasone group 15 minutes after the local anesthetic injection (at time of access cavity preparation) The success of the anesthesia was defined as the tooth without pain or with mild pain according to the Heft-Parker visual analog scale (HP-VAS ≤ 54). This scale is a 170-mm horizontal line, divided into 4 categories. No pain corresponded to 0 mm; mild pain was defined as \>0 mm and 54 mm. Mild pain category included faint, weak and mild pain. A score \>54 mm and \<114 mm indicated moderate pain and included the descriptor of moderate pain. A score \>54 mm and \<114 mm indicated moderate pain and included the descriptor of moderate pain. Severe pain was defined as ≥114 mm. Severe pain was defined as strong, intense and maximum possible.
