ABSTRACT

The elimination of dentinal debris deposited on the surface of endodontic instruments is a pre-sterilization objective to avoid the risk of cross-infection. Objective: To evaluate the cleaning caused by an innovative Nd: Yag laser method to remove surface accumulated dentin debris from Protaper Next Nickel-Titanium X2 endodontic instruments. Materials and Methods: In vitro (n = 12 sides) experiment of 6 Protaper Next X2 and 6 Primary Wave One Gold instruments in which endodontic instruments with Van Gieson solution were stained under stereoscopic microscopy on used instruments and subsequently treated with 2 different methods of cleaning: Group A: Nd: Yag laser (250 mJ, 3Hz) or Group B: Ultrasound (15 minutes). The remaining stained debris was categorized for analysis. Images were obtained under stereoscopic microscopy (35X) evaluated by 2 calibrated endodontists. Data were analyzed with the Kruskal Wallis test in the SPSS 21 program at alpha .05. Results: The Nd: Yag laser significantly eliminates dentin debris adhering to the surface of nickel titanium instruments than the ultrasonic cleaning method (p ‹0.05). Conclusions: The Nd: Yag laser is an effective method for cleaning the surface of nickel-titanium rotary instruments prior to sterilization.
