Antimicrobial Effect of Calcium Silicate and Pectin as Intracanal Medications in Necrotic Teeth With Periapical Lesions

Antimicrobial Effect of Calcium Silicate and Pectin as Intracanal Medications in Necrotic Teeth With Periapical Lesions :A Randomized Controlled Clinical Trial

It is tackling antimicrobial resistance in endodontics, specifically comparing different intracanal medications used in root canal treatment. Given the growing concern over resistant bacterial strains, our study aims to evaluate the effectiveness of various medicaments in eliminating endodontic pathogens while minimising the risk of resistance development. By integrating microbiological analysis and clinical relevance, our research seeks to provide evidence-based recommendations for optimising intracanal disinfection protocols and improving treatment outcomes in endodontic infections.

Inclusion Criteria

• Patients presenting with a single rooted mandibular premolar tooth with a closed apex and a single patent canal type I in Vertucci's classification (Vertucci et al., 1974).
