Evaluation of antibacterial effect of two different intracanal medicaments on bacterial load in infected mature permanent teeth and their effect on post-operative pain level.
free medical history,
mature infected permanent single rooted teeth diagnosed clinically and radiographically with adequate coronal structure for proper isolation, temporization and restoration.
Patients who are not included in the age range of the study or having a systemic condition.
Teeth with severe fractures or resorption or periodontally compromised.
Parallel
Calcium Hydroxide (Ca(OH)2)
DrugNon setting calcium hydroxide intracanal medicament is injected through the root canal for two weeks
chitosan nanoparticles gel
DrugNano chitosan gel is injected through the root canal as an intracanal medicament for two weeks
Bacterial load.
Samples will be collected from the infected root canal before and after injection of intracanal medicaments then bacterial colonies will be counted for colony forming units per milliliter (CFU/ml) to assess the effect of the intracanal medicaments used.
Visual Analogue Scale (VAS) to measure post operative pain level.
the patient is given a 10 cm sheet to mark their pain level where (0) represents no pain and (10) the worst pain.
