Assessment of Precipitate Formation on Interaction of Chlorhexidine with Sodium Hypochlorite, Neem, Aloevera and Garlic: An in vitro Study

Introduction: Irrigants play an important role in debridement and disinfection of root canal space. Precipitate formed from combination of irrigants during root canal treatment may affect the properties of intracanal medicaments and adaptation of obturated materials to the root 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).
