The Effect of Intra-pulpal Anesthesia With Cryotherapy on Intra-operative Pain

The goal of this clinical trial is to compare the effect of cooling of local anesthesia on intraoperative pain during root canal treatment in mandibular molars diagnosed as symptomatic irreversible pulpitis. The main question it aims to answer is: Is there a difference in intra-operative pain levels using intra-pulpal anesthesia with and without cryotherapy during root canal treatment? Participants will undergo root canal treatment using intrapulpal anesthesia with and without cooling. Researchers will compare cold and room temperature intrapulpal anesthesia to see the intensity of intraoperative pain.

Inclusion Criteria: * Patients with mandibular molars diagnosed with symptomatic irreversible pulpitis. * Mandibular molars with closed apices. * Patients who are experiencing pain during access cavity drilling above 5 visual analog scale. Exclusion Criteria: * • Patients with a known allergy to lidocaine. * Root canal-treated mandibular molars. * Patients with systemic diseases. * Mandibular molars with open apices. * Mandibular molars with external/internal resorption. * Non-restorable mandibular molars.
