First cordless ultrasonic handpiece for irrigant activation
Open the catalog to page 1Instrumental shaping: a perfectly clean root canal? ■■ At least 35% of the root canal walls remain non-instrumented during the prepa- ration due to the complex endodontic anatomy, regardless of the shaping technique (Peters et al. 1, 2001). ■■ Shaping produces smear layer which accumulates on the root canal walls and obstructs the tubules thus limiting their disinfection during irrigation. Instrumented surface during root canal preparation Non-instrumented surface during root canal preparation (a) 3D representations obtained through densitometry, Siqueira et al.2, 20
Open the catalog to page 2How to optimize your endodontic treatment? ■■ Opening the tubules and making the irrigating solutions circulate into all aspects of the root canal system are essential for optimal cleaning and efficient disinfection. ■■ The activation of the irrigant using ultrasonic techniques allows for a significantly cleaner root canal system (Nusstein et al. 3, 2005). Passive irrigation without activation: incomplete disinfection Cleaning at 27% (isthmus), 70% (mesiolingual canal), and 95% (mesiobuccal canal). Passive ultrasonic irrigation: optimized disinfection Cleaning at 99.8% (isthmus) and 100%...

Open the catalog to page 6Reduces the microbial load Improved activation Better root canal debridement with ultrasonic technology compared to conventional or sonic methods (Van der Luis et al.8, 2009). Other studies 9 also show the higher efficiency of ultrasonic systems for the opening of tubules obstructed by smear layer as well as their superior disinfection quality.

Postoperative x-ray after root canal shaping with One G and 2Shape systems. 5 successive irrigation cycles with NaOCl activated with EndoUltraTM during 30 seconds. Final rinse with EDTA, activation and distilled water before obturation. The efficiency of the NaOCl activation with EndoUltraTM allowed for the obturation of a secondary root canal in the apical third of this premolar.
