GARCIA DELGADO, A. et al. Ultrasonic devices for root canal system irrigation. Av Odontoestomatol [online]. 2014, vol.30, n.2, pp.79-94. ISSN 2340-3152.

Removal of vital and necrotic remnants of pulp tissues and microorganisms from the root canal system is essential for endodontic success. Disinfection of the root canal by irrigation and instrumentation are the most important factors in the prevention and treatment of apical periodontitis. As it is impossible for the instruments to reach all the areas of the root canal system, the irrigation has gained special importance. Due to this fact, technological advances during the last decade have brought new delivery and agitation devices, such as ultrasonic devices. Particularly, this review article assesses the available information from the last ten years about the effectiveness of ultrasonic devices to remove bacteria, pulp tissue, dentin debris and smear layer, and the ability of these devices to make the irrigant solution penetrate into the root canal system and the safety of its use. Nowadays scientific literature reveals that ultrasonic devices are more effective on chemical, biological and physical debridement of the root canal system than conventional technique and being safety devices at the same time.
