About this trial
The aim is to compare the contributions of intraoral cryotherapy and supplemental lingual infiltration anesthesia to buccal infiltration anesthesia in mandibular incisor teeth with irreversible pulpitis in terms of anesthetic efficacy, and to evaluate the effect of adding intraoral cryotherapy to buccal anesthesia on anesthetic efficacy.

Cryotherapy
Other interventionIntraoral cryotherapy will be applied using small ice packs wrapped in sterile gauze and placed into the vestibular sulcus adjacent to the target mandibular incisor. Participants will be instructed to maintain the ice pack in position for approximately 5 minutes prior to the anesthetic procedure. If discomfort occurs, participants will be allowed to briefly remove the ice pack and reapply it once comfort is restored. This intervention is intended to induce local vasoconstriction and reduce nerve conduction to enhance anesthetic efficacy.

Trial outcomes
Primary outcomes
Anesthetic Success Rate During Endodontic Treatment
Anesthetic success will be defined as the absence of moderate or severe pain during pulpectomy procedures. Pain intensity will be assessed using Numerical Rating Scale (NRS). Anesthetic failure will be recorded if the participant reports moderate to severe pain, requires supplemental anesthesia, or shows positive response to electric pulp testing.
Anesthetic success rate
Anesthetic success will be defined as the absence of moderate or severe pain during pulpectomy procedures. Pain intensity will be assessed using Wong-Baker FACES scale. Anesthetic failure will be recorded if the participant reports moderate to severe pain, requires supplemental anesthesia, or shows positive response to electric pulp testing.
Secondary outcomes
Intraoperative Pain During Pulpectomy
Pain intensity experienced during pulpectomy will be recorded using the Numerical Rating Scale (NRS) at any stage of treatment before pulp extirpation.
Pain intensity during pulp extirpation
Pain intensity experienced during pulpectomy will be recorded using the Wong-Baker FACES scale at any stage of treatment before pulp extirpation.
Other outcomes
Need for Supplemental Anesthesia
The requirement for additional intraligamentary anesthesia during treatment will be recorded as an indicator of anesthetic failure.
Oral Mucosal Temperature Changes
Changes in oral mucosal surface temperature following anesthetic and/or cryotherapy application will be measured using thermal imaging. The lowest recorded temperature and duration of temperature change will be analyzed.
