Overview
Clinical Evaluation of the Postoperative Pain and Substance P levels Following the use of Bioceramic verses Calcium Hydroxide Intracanal Medicaments in Permanent Mandibular molars with Symptomatic Apical Periodontitis
Description
This study aims to evaluate postoperative pain levels and Substance P expression following the use of two different intracanal medicaments: bioceramic materials and calcium hydroxide in permanent mandibular molars diagnosed with symptomatic apical periodontitis.
A total of 28 patients will be included in this study and randomly allocated into two equal groups (n=14 each). Group I will receive calcium hydroxide (Ca(OH)₂) as an intracanal medicament, while Group II will receive a bioceramic intracanal medicament.
Standardized endodontic procedures will be performed for all participants. Postoperative pain will be assessed using a visual analog scale (VAS) at different time intervals following treatment.
In addition, samples will be collected to evaluate Substance P levels as a biochemical marker associated with pain and inflammation.
The comparison between the two groups will help determine the effectiveness of each intracanal medicament in reducing postoperative pain and inflammatory response. The results of this study may contribute to improving clinical decision-making in endodontic therapy.
