Results showed that mechanical active irrigation reduces post-operative pain .
It improved debridement , canal/isthmus cleanliness .
It also improved delivery of irrigant up to working length .
Bacterial count was more with active irrigation , though not significant .
There is no effect on long-term periapical healing .
Conclusion It may be concluded that mechanical active irrigation devices are beneficial in reducing post-operative pain and improving canal and isthmus cleanliness during Endodontics
Objective Irrigant activation has been cl aim ed to be beneficial in in vitro and clinical studies .
This systematic review aims to investigate the clinical efficiency of mechanically activated irrigants and conventional irrigation .
Clinical study of single-visit root canal treatment with a nickel-titanium (Ni-Ti) rotary instrument combined with different ultrasonic irrigation solutions for elderly patients with chronic apical periodontitis.
The study involved 300 elderly patients with chronic periapical periodontitis . The patients were r and omly assigned into three groups . The treatment for group A used a Mtwo Ni-Ti rotary instrument combined with ultrasonic irrigation of a 2.5 % NaOCl solution . The group B used the same instrument combined with ultrasonic irrigation of an active silver ion antibacterial solution . The group C used the same instrument combined with syringe irrigation of a 2.5 % NaOCl solution . The root canal fillings were performed immediately after canal preparation . Twenty-four hours after the procedure , patients self-assessed pain levels according to the VAS table . The three groups returned after seven days so their postoperative acute reactions could be evaluated clinical ly . After six and twelve months , efficacy was evaluated . The self-assessed pain levels for group A and B were significantly lower than group C. The incidence of postoperative acute reactions after seven days for group A and B were significantly lower than those of group C. The effective rates after six and twelve months did not differ among these groups . The single-visit root canal treatment with a nickel-titanium rotary instrument combined with ultrasonic irrigation for elderly patients with chronic periapical periodontitis achieved short and long term efficacy and stability
