Primary Endpoint
The level of Neurokinin A in gingival crevicular fluid samples of teeth diagnosed with symptomatic irreversible pulpitis with symptomatic apical peridontitis and the contralateral teeth with healthy normal pulp.

Overview

Brief Summary

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.

Detailed Description

The study design is Comparative Cross sectional study. The study will be conducted at the Dental hospital of Cairo University with access to patients undergoing treatment for teeth with pulpitis and apical periodontitis.

Accepts Healthy Volunteers
No

Inclusion Criteria

  • Adults (aged 18-60) diagnosed with symptomatic irreversible pulpitis with symptomatic apical periodontitis and have healthy contralateral teeth with normal pulp.
  • The involved teeth should have healthy periodontal conditions (Normal periodontal pocket depth, No bleeding on Probing and No mobility).
  • Patients who have not undergone any previous dental treatments in the involved teeth.
  • Signed informed consent.

Exclusion Criteria

  • Patients with systemic diseases affecting the immune response (e.g., autoimmune diseases, uncontrolled diabetes).
  • Patients taking medications that can affect the inflammatory markers (e.g., Steroids and Tetracyclins).
  • Individuals with periodontal disease unrelated to apical periodontitis.
  • Presence of marginal bone loss.
  • Pregnant women.

Outcomes

Primary Outcomes

The level of Neurokinin A in gingival crevicular fluid samples of teeth diagnosed with symptomatic irreversible pulpitis with symptomatic apical peridontitis and the contralateral teeth with healthy normal pulp.

Time Frame: Pre-operative measurement for Neurokinin A in gingival crevicular fluid samples

Method of Measurement: Human Neurokinin A ELISA Kit (Bioassay Technology Laboratory, Shanghai, China) - Unit of measurement: Pg/ml

Secondary Outcomes

  • A- The level of MMP-9 in gingival crevicular fluid samples of the symptomatic teeth and the contralateral teeth with normal pulp. B- The pre-operative pain severity in relation with the levels of these diagnostic biomarkers (Nerokinin A and MMP-9).(A- Pre-operative measurement for Matrix Metalloproteinase 9 in gingival crevicular fluid samples. B- Pre-operative pain severity assessment to corelate it with the levels of these diagnostic biomarkers (Nerokinin A and MMP-9)..)
