Assessment of Precipitate Formation on Interaction of Chlorhexidine with Sodium Hypochlorite, Neem, Aloevera and Garlic: An in vitro Study
Subscribe/Renew Journal
Introduction: Irrigants play an important role in debridement and disinfection of ischolar_main canal space. Precipitate formed from combination of irrigants during ischolar_main canal treatment may affect the properties of intracanal medicaments and adaptation of obturated materials to the ischolar_main canal walls.
Aim: To check for precipitate formation from various irrigant combinations and to weigh the amount of precipitate formed.
Methods and Material: Five different irrigants namely 2% CHX gluconate, 3% NaOCl, 5% Neem, 5% Aloevera, and 5% Garlic were taken in different test tubes. 1mL each of two different irrigants were mixed in 10 test tubes and observed for 2 min for formation of any precipitate and the formed precipitate was weighed.
Results: 1mL 2% CHX + 1mL 3% NaOCl and 1mL 2% CHX + 1mL 5% Neem showed precipitate formation immediately. Through statistical analysis it was observed that more amount of precipitate was seen in 1mL 2% CHX + 1mL 5% Neem followed by 1mL 2% CHX + 1mL 3% NaOCl.
Conclusion: Precipitate formation is seen more with the 2% CHX‐5% Neem when compared with the control group (2% CHX-3% NaOCl).
