Period pain meets tooth pain: study asks if menstrual phase impacts dental anesthesia
NCT ID NCT07306533
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether the phase of a woman's menstrual cycle changes how well dental numbing works for treating a painful tooth condition called pulpitis. Researchers will give 150 women a standard numbing shot and measure pain during treatment. The goal is to see if certain cycle phases make the numbing less effective, which could help dentists plan better care.
