Comparison of Antimicrobial Action of Sodium Hypochlorite and Polyhexamethylene Biguanide as Root Canal Irrigants

Altamash Institute of Dental Medicine60 enrolled

Overview

The aim of this randomized clinical trial is to compare the antibacterial effects of sodium hypochlorite (NaOCl) and Polyhexamethylene biguanide during root canal treatment .

This study will compare the antibacterial effectiveness of sodium hypochlorite and PHMB, to find out whether PHMB can be used as a substitute to NaOCL. Polyhexamethylene biguanide (PHMB), is a disinfectant solution having a broad spectrum of antimicrobial activity and is investigated as an endodontic irrigant. It is non-corrosive, non-toxic and acts by disrupting cell membrane integrity.

Polyhexamethylene biguanideDRUG

Polyhexamethylene biguanide (PHMB), is a disinfectant solution having a broad spectrum of antimicrobial activity and is investigated as an endodontic irrigant

Sodium HypochloriteDRUG

A number of irrigant solution has thus been proposed to serve the purpose, the most popular being sodium hypochlorite (NaOCl) because of its excellent antimicrobial activity but also the ability to dissolve organic matter

Outcomes

Primary Outcomes

Bacterial load assessed by culture

Effectiveness of irrigant will be evaluated with the existence or non-existence of bacteria: Positive Effect = no bacteria exist, Negative Effect = bacteria exist. Bacterial analysis will be performed by counting the number of colonies of bacteria in the specimen: No growth = no colonies seen, Few growths = less than 10 colonies of bacteria seen, Moderate growth = less than 100 colonies more than 10 colonies of bacteria seen, Heavy growth = more than 100 colonies of bacteria seen.
