Postoperative Pain After Single-Cone Root Canal Obturation Using Three Sealers

The goal of this clinical trial is to compare post-treatment pain after root canal therapy in adults with irreversible pulpitis using different root canal sealers. The study will also evaluate the need for pain medication after treatment. The main questions this study aims to answer are: Does the type of root canal sealer affect the intensity of pain after treatment? Does the type of sealer influence the number of analgesic tablets taken by participants? How does pain change over time after treatment with different sealers? Researchers will compare two bioceramic sealers (EndoSeal TCS and NeoSeal) with a resin-based sealer (AH Plus) to determine their effects on post-endodontic pain. Participants will: Receive root canal treatment using one of the study sealers Report their pain intensity at specific time points after treatment Record the number of analgesic tablets taken during the follow-up period

Neurokinin A and Matrix Metalloproteinase 9 Levels in Gingival Crevicular Fluid Samples of Teeth With Symptomatic Irreversible Pulpitis With Symptomatic Apical Periodontitis

The aim of this study is to investigate the levels Neurokinin A and of Matrix Mtalloproteinase (MMP-9) in gingival crevicular fluid samples (GCF) as potential biomarkers for the diagnosis of symptomatic irreversible pulpitis with symptomatic apical periodontitis and to correlate the level of these diagnostic biomarkers ( Nerokinin A and MMP-9) with the pre-operative pain severity using the Numerical Rating Scale (NRS). This study will utilize a comparative cross-sectional design to assess the levels of Neurokinin A (NKA) and Matrix metalloproteinase-9 (MMP-9) in gingival crevicular fluid (GCF) samples from symptomatic and healthy contralateral teeth with normal pulp.
