The EndoActivator is designed to safely and vigorously energize the hydrodynamic phenomenon. Evidence-based endodontics has shown that cavitation and acoustic streaming significantly improve debridement and the disruption of the smear layer and biofilm. Activating fluids promote deep cleaning and disinfection into lateral canals, fins, webs, and anastomoses. A cleaned root canal system facilitates 3-D obturation and long-term success.

SmartLite Pro Platform

The SmartLite Pro (SLP) platform is a unique, modular design, and multi-functional system comprised of a cordless, pen-style handpiece, and 3 interchangeable, quick-connect attachments. Of the 3 attachments, one provides a curing light, a second is for transillumination, and the third is a sonically-powered SLP EndoActivator attachment. The SLP EndoActivator attachment is designed to drive new and improved snap-on polymer tips, which in turn, serve to activate and exchange an irrigant, while vigorously producing the hydrodynamic phenomenon. Note the SLP platform provides 2 latest generation lithium iron phosphate batteries to power the handpiece and any given attachment. The platform is designed to organize and simplify the clinical workflow, but the clinician has choice and can acquire any attachment, as desired.

SLP EndoActivator Handpiece

The original EndoActivator has been utilized widely in the marketplace since 2007, and has been featured in more than 50 scientific, peer-reviewed published papers. The new SLP EndoActivator builds on that cleaning and disinfection technology. SLP EndoActivator features include:

  • Contra-angled design for easy access to posterior teeth
  • Ergonomic, cordless, rechargeable and ULTRA quiet
  • Drives tips in a novel, random elliptical motion
  • 2-speed sonic motor for endodontic disinfection (18,000cpm) and adjunctive (3,000cpm) procedures

SLP EndoActivator Tips

The EndoActivator Tips are available in two sizes: Small (Yellow 15/02, 22mm length) and Red (Medium 25/04, 22 & 28 mm lengths). Specific features include:

  • New paddle-like, parallelogram-shaped cross-sectional design and elliptical motion for improved fluid exchange
  • Easy snap-on / snap-off design
  • Strong, flexible, medical-grade polymer composition
  • Clean guard component for the deflection of aerosols
  • Convenient depth gauge rings

SLP EndoActivator Protocol

  • Shape in the Presence of 6% NaOCl
  • Select EndoActivator Tip
  • Activate 17% EDTA for 1 Minute
  • Activate 6% NaOCl for 30 Seconds

NOTE: The vibrating Activator tip is synergistically used with a pumping motion in a crown-down manner to produce “active” irrigation. A cloud of debris is frequently observed within a fluid-filled pulp chamber. Repeat this process for each canal or until the fluid in the pulp chamber is clinically observed to be visually clear. Observe the powerful activation of fluid and appreciate the suborifice potential for 3D cleaning.

Clinical Applications

The EndoActivator System is designed to provide a safer, better, and faster way to achieve success in the following clinical applications:

  • Debridement and disruption of the smear layer and biofilm
  • Placement of calcium hydroxide and MTA around root curvatures
  • Removal of residual obturation materials during retreatment procedures

Overall, for 3D disinfection, hydrodynamic activation serves to improve the penetration, circulation, and exchange of an irrigant into both the instrumentable and uninstrumentable regions of the root canal as shown in the plastic block simulation. SEM images also provide evidence that the EndoActivator system can clean root canal systems. Note the deep lateral cleaning into the dentinal tubules. A stained axial cross-section demonstrates the depth of exchange of silver ions deep into the dentinal tubules after using the SLP EndoActivator.
