Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study will investigate the impact of an additional injection of long-acting anesthetic on pain level, quality of life, and use of pain medication after a nonsurgical endodontic treatment. The long-acting anesthetic will be compared to a mock injection group and a group with no additional anesthetic to determine any differences in effects.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study will investigate the impact of postoperative supplemental long-acting bupivacaine on patient's pain, quality of life, and analgesic use following treatment for symptomatic irreversible pulpitis on patients with pre-operative pain levels of 5 or above (on a 0-10 analog scale). Bupivacaine will be compared to a placebo/mock injection and no injection to determine the difference in effect.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Three types of additional treatment after standard nonsurgical endodontic procedures may be given. These include an additional injection of bupivacaine, an additional mock or placebo injection, and no additional injection.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Supplemental Postoperative Bupivacaine

An additional injection, 1 carpule (1.8 mL) of 0.5% bupivacaine with 1:200,000 epinephrine, will be given to patients in this treatment arm, after their standard endodontic procedure is complete.

Group Type EXPERIMENTAL

Supplemental Postoperative Bupivacaine

Intervention Type DRUG

This is the intervention of interest. A supplemental injection of bupivacaine will be given postoperatively to patients who are assigned this intervention.

Mock/Placebo Injection

If assigned to this arm, the patient will be shown the removal of a needle cap for an anesthetic syringe. The tip will be bent and placed in the patient's mouth, but no tissue penetration will occur. No solution of anesthetic will be delivered.

Group Type PLACEBO_COMPARATOR

Placebo Injection

Intervention Type DRUG

This intervention will appear to give patients an additional injection, but no additional drug will be given.

No Additional Injection

After standard endodontic procedure, no additional injection will be given.

Group Type NO_INTERVENTION

No interventions assigned to this group
