Effect of cryotherapy and laser treatment in management of pain after root canal treatment

Phase 4

Not yet recruiting

Brief Summary: Randomized clinical trial will be performed in patients diagnosed with symptomatic apical periodontitis. Preoperative pain scores will be recorded using Visual Analog Scale(VAS) before initiating root canal treatment by an evaluator who is blinded to randomization. Standard Inferior Alveolar Nerve Block and Buccal infiltration using 2% lidocaine with 1:2,00,000 epinephrine will be administered in mandibular and maxillary molars, respectively. The participants will be randomly divided into groups(n=20 in each group). Group A- normal saline, Group B- intracanal cryotherapy and Group C- intracanal laser irradiation. Single sitting root canal treatment will be carried out. Access opening will be done with an Endo-access bur and de-roofing of the pulp chamber with Endo-Z bur, cleaning and shaping will be done in all the groups. In Group A, the final irrigant will be normal saline, in Group B, 4 degrees cold saline will be the final irrigant and in Group C, low level laser irradiation will be done with diode laser. In all the groups, combination of single cone and warm vertical obturation will be carried out followed by composite access restoration. VAS scores will be recorded for during and after the root canal treatment and verbal analog scale scores will be recorded uptill 7 days.
