Comparing two numbing shots for painful lower first molars
Part of Mouth & dental clinical trials.
This study compares two numbing methods for severe tooth pain (pulpitis) in a lower first molar. If you have a tooth that needs a root canal and the pain lingers after cold, this trial may help determine which anesthetic works better for you.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 55 years old.
- You need a root canal on a lower first molar and the tooth is still alive (not dead or abscessed).
- You have severe tooth pain that lingers for more than 10 seconds after something cold touches it.
- You have not taken any painkillers for at least 6 hours before the appointment.
- You are not allergic to lidocaine, articaine, or epinephrine (common dental numbing medicines).
- You do not have serious medical conditions, are not pregnant or breastfeeding, and are not on blood thinners or high blood pressure medication.

This trial tests if warming the numbing medicine before injecting it into the jaw makes the numbing work better for people with a painful tooth infection. If you have a bad toothache in a lower molar and need a dental procedure, this study might help make the numbing more effective.
This study compares two numbing methods for removing a lower wisdom tooth. One is an injection near the tooth and the other is a nerve block. It aims to see which works better and may be more comfortable.
This trial compares two ways to numb a painful lower back molar. If you have a tooth infection that needs a root canal, you may receive one of two injection techniques to see which works better.
This study compares two types of numbing medicine used for simple tooth extractions to see which works better. If you need a tooth pulled and are in good health, you may be able to join.
This study tests whether applying cold to your gum before a numbing injection helps the anesthetic work better for a severely painful lower front tooth. Researchers want to see if this simple cooling step reduces pain during the procedure.
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.
