The goal of this randomized clinical trial is to evaluate pain after root canal treatment using two different kinds of sealers during obturation in 60 healthy , male and female patients ages between 18 to 40 years. The main aims is to systematically evaluate and compare post-operative pain levels in patients undergoing root canal treatment with two different types of endodontic sealers: AH plus (SEAL APEX) and bio ceramic sealer(META)

• By identifying the sealer that leads to the least discomfort, this research could significantly enhance patient care, minimize recovery time, and improve overall treatment success in endodontics.

Participants in both groups will be given a visual analogue scale(VAS) to measure the pain level after the root canal treatment has been completed. They will measure pain levels at 12, 24 and 48 hours. All information will be recorded on proforma and compared.

•This randomized clinical trial is done to evaluate and compare post operative pain after obturation using two different sealers .A total of 60 participants will be selected using a non-probability consecutive sampling method. After enrollment, participants will be randomly allocated into two equal groups (30 each),Group A and Group B using the lottery method. Group A patients will be given AH plus sealer and Group B will be given bio-ceramic sealer. Root canal treatment will be performed in two visits using local anesthesia under rubber dam isolation. • After drying with paper points , in group 1 an even ratio of 1:1 from the base and catalyst of the AH plus will be manually mixed on a paper pad with a spatula and introduced into the canal on the master cone.

• In group B, sealer will be introduced with the bio ceramic sealer tube and cold lateral compaction technique will be used for obturation in both of the groups . Composite will be used for restoration.
• The patients will be called again for evaluation of pain and its severity at, 24hrs, 48hrs and 72hrs. Effectiveness of sealers will be measured as no, mild, moderate or severe pain on visual analogue scale (VAS). All procedures will be done under the supervision of supervisor. All this information will be recorded on proforma.
• Patients shall be prescribed ibuprofen 400mg post-operatively shall be prescribed. Patients will be given VAS scale so they can record their pain at home before taking the analgesic.
• Data will be entered and analyzed in IMB SPSS version 26. Mean and Standard deviation (SD) of VAS scores at each time point (12h, 24h, 48h) for both types of sealers shall be calculated. Independent t-test to compare the VAS scores between two groups (Sealer 1 vs. Sealer 2).
• Significance level to set at p value <0.05 this study will further add to the literature regarding the efficacy of sealer in reducing post operative pain and assessing which sealer is better and effective to use for clinicians.
