Steroid before numbing for painful lower molar root canals
Treatments studied
Part of Mouth & dental clinical trials.
This trial tests whether giving a steroid medicine (dexamethasone) before numbing a painful lower molar makes the numbing work better during a root canal. It may help reduce pain and improve the success of anesthesia.
Summary written for real people, not researchers, by Clin2.

Other trials that look related to this one.
This trial is testing two cold-therapy techniques applied directly to the tooth nerve to see which one better reduces pain during a root canal treatment. It aims to make the anesthesia work faster and more effectively, so you feel less discomfort during the procedure.
This trial tests if activating a sealer inside a tooth after root canal can reduce pain in the days after treatment. It may help people with a painful lower molar that still has a live nerve.
This trial tests whether a single injection of dexamethasone (a steroid) near the nerve of a painful lower molar can improve pain relief during a root canal. It's for people with severe tooth nerve pain who haven't taken pain meds recently.
This study looks at whether putting a common steroid medicine (dexamethasone) inside the tooth during a root canal can reduce pain after the procedure. If you have a painful tooth with an inflamed nerve, this treatment might help you feel better faster.
This study tests whether taking ibuprofen or dexamethasone before a root canal can help reduce pain afterward. It's for people with a painful, inflamed tooth nerve who haven't already taken pain medicine for it.
This study tests whether applying cold (cryotherapy) to the gum and tooth before the numbing shot can make the anesthesia work better and reduce pain during a root canal for a severely inflamed tooth. If it works, the dentist's numbing may be more effective and you may feel less discomfort during the procedure.
