Effectiveness of Cryotherapy on Endodontic Pain

Phase 2

Recruiting

• Conditions: Post Operative Pain
• Interventions: Drug: Irrigation Solution

• Registration Number: NCT06785753
• Lead Sponsor: Armed Forces Institute of Dentistry, Pakistan

Brief Summary

This is a randomized , prospective , control trial to assess the effectiveness of intracanal cryotherapy on post operative pain after root canal treatment in patients with symptomatic apical periodontitis

Detailed Description

Diagnostic procedures to include patients history taking , clinical and radiographic with all findings being recorded in patients .

patients diagnosed with symptomatic irreversible pulpitis with symptomatic apical periodontitis.

patients will be asked to rate their pre treatment pain on visual analogue scale from 0-10

patients with pain score \<8 will be considered

Anesthesia and isolation : after administration of local anesthesia , rubber dam application will be done

Acess cavity : acess will be gained with round bur using air turbune handpiece with copious water cooling

Working length : a size 10k file will be inserted into the canal to determine the working length with the help of radiograph

Cleaning and shaping : Extirpation of pulp will be done followed by canal preparation with manual and endodontic motor using naocl and EDTA .

final irrigation will be performed using 17% EDTA and 5.25% NaOCl

Patients will be divided into 2 group in control group : final irrigation will be done using 5ml of saline at room temperature in cold group : final irrigation will be done using 5ml of cold saline at 2.5°C

the solution will be stored in the refrigerator until use irrigation will be performed for 5 min in both groups using 27 G beveled needle tip inserted 2mm short of WL.

Obturation ; In both groups , canals will be dried with paper points and obturated using gutta percha cones with zinc oxide eugenol sealer

Restoration : acces cavity will be restroed with direct composite restoration or high viscosity glass ionomer cement

each patient will be given instruction to acess the post operative pain .

Arm && Interventions

Group	Intervention	Description
normal saline group	Irrigation Solution	In control group , canals will be irrigated with 5ml of normal saline at room temperature
cryotherapy (cold saline group)	Irrigation Solution	in cold saline group , canals will be irrigated with 5 ml of cold saline at a temperature of 2.5° C

Primary Outcome Measures

Name	Time	Method
post operative pain after root canal treatment	1 week	post operative pain will be assessed using visual analogue scale ( VAS) from 0-10 each patient will be given instruction to access the post operative pain . it will be carried out using a questionnaire.; VAS 0-1 = No pain 2-3 = mild pain 4-6 = moderate pain 7-10 = severe pain pain recording will be done at 6 hrs , 24 hrs, 48hrs and 72 hrs. ( participants to be contacted by investigator at each point to check on them and remind them to record their pain ). The given questionnaire shall be collected when the participant comes for final restoration after 1 week
