NCT05338671

Brief Summary

This study will assess the efficacy of two local anesthetics (2% lidocaine 1:100,000 epinephrine and 0.5% bupivicaine 1:200,000 epinephrine) in reducing post-operative pain in patients receiving endodontic treatment.

Outcome Measures

Primary Outcomes (5)

  • Post-operative Pain Level 6 Hours on a Visual Analog Scale

    Participants will be asked to track the amount of pain they have following their endodontic treatment using the Heft-Parker visual analog scale with scores ranging from 0-170 with higher scores signifying more pain.

    Patients will be asked to track pain levels at 6 post-operatively on a visual analog scale

  • Post-operative Pain Level 12 Hours on a Visual Analog Scale

    Participants will be asked to track the amount of pain they have following their endodontic treatment using the Heft-Parker visual analog scale with scores ranging from 0-170 with higher scores signifying more pain.

    Patients will be asked to track pain level at 12 hours post-operatively on a visual analog scale

  • Post-operative Pain Level 24 Hours on a Visual Analog Scale

    Participants will be asked to track the amount of pain they have following their endodontic treatment using the Heft-Parker visual analog scale with scores ranging from 0-170 with higher scores signifying more pain.

    Patients will be asked to track pain level at 24 hours post-operatively on a visual analog scale

  • Post-operative Pain Level 48 Hours on a Visual Analog Scale

    Participants will be asked to track the amount of pain they have following their endodontic treatment using the Heft-Parker visual analog scale with scores ranging from 0-170 with higher scores signifying more pain.

    Patients will be asked to track pain level at 48 hours post-operatively on a visual analog scale

  • Post-operative Pain Level 72 Hours on a Visual Analog Scale

    Participants will be asked to track the amount of pain they have following their endodontic treatment using the Heft-Parker visual analog scale with scores ranging from 0-170 with higher scores signifying more pain.

    Patients will be asked to track pain level at 72 hours post-operatively on a visual analog scale

Limitations and Caveats

Limitations/future direction * Sample size * Lack of a control group: Inferior alveolar nerve block with saline solution * Lack of inclusion of other pre-operative pulpal diagnoses: Pulp Necrosis, Previously Initiated Therapy, Previously Treated * Lack of inclusion of maxillary posterior teeth * We could have tracked patients for longer periods of time to examine persistent pain
