RESUMEN

The fracture of an endodontic instrument is an obstacle in completion of a routine successful pulp space therapy. Ni-Ti instruments corrode when in contact with sodium hypochlorite which leads to their deterioration and ultimately fracture during use. Removal of separated instrument from root canal is often a very difficult procedure. This procedure is more complicated when the instrument separated is closer to the mandibular canal. A case is presented in which a separated hand instrument was retrieved from the mesio buccal of a second molar approximating the mandibular canal root by replantation.

RESUMEN

Introduction: Irrigants play an essential role in the successful debridement and disinfection of pulp space. Various combination of irrigants used during root canal treatment enhance their efficacy, but some form precipitates which affects the diffusion of intracanal medicaments and the seal of the obturated root canal. Aim: To evaluate the combination of various irrigants whether it forms the precipitate and also to quantify the amount of precipitate formed. Materials and Methods: Five different irrigants were taken in ten test tubes each having the combination of two irrigants and observed for 2 min for precipitate formation. Results: One-way-ANOVA test revealed more amounts of precipitate with 2% Chlorhexidine (CHX) 5% Tulsi followed by 2% CHX, 5% Neem and 3% Sodium hypochlorite 2% CHX. Conclusion: Precipitate formation is seen more with the 2% CHX-5% Neem followed by 2% CHX-5% Tulsi when compared with the control group. When these combinations of irrigants were used, intermediate flushes of saline or distilled water reduced the amount of precipitate.
