iVac PeekSonic Ultrasonic Irrigation Activation Tips
  • FAQs
Product Details

    Traditional metal ultrasonic irrigation tips are inflexible and brittle, prone to breaking during use. Pac-Dent's Peeksonic is made of a durable, flexible PEEK polymer that can navigate canal curves without damaging them. PeekSonic is also unaffected by ultrasonic power and has a low risk of breaking. It is compatible with various piezo ultrasonic devices, whether S or E types.

    PeekSonic activation tip uses a vibration resonance pattern to clean canal areas unreachable by mechanical instruments. The 29KHz frequency creates sheer forces that remove debris, smear layer, and biofilm from dentin walls, improving canal cleaning and opening dentin tubules.

    Advantages

    ● Small tip diameter (.25 mm) with a .02 taper allows navigating the canals even after minimally invasive preparations.
    ● PEEK polymer tip vibrates at a similar resonance as metal with higher resistance compared to stainless steel and NiTi tips
    ● Flexible, following the canal curvatures without compromising the vibration amplitude
    ● Easy and intuitive setup and operation
    ● Can be pre-bent for easier insertion in posterior teeth
    ● Low cost per procedure
    ● Adaptable to the majority of piezo ultrasonic devices (S and E) and final irrigation protocols

    PeekSonic ultrasonic activation significantly accelerates the dissolution of pulp tissue during chemo-mechanical preparation. PeekSonic+PUI accelerates pulp tissue dissolution by four times, while PeekSonic+CUI accelerates it by eight times compared to non-activated sodium hypochlorite with the same concentration.

    Product details

    ● Can be sterilized by autoclave
    ● 28mm length
    ● Tip diameter is 25, taper 0.2
    ● Package with four blisters with five tips each (20 per package)
    ● Reference # 952201
    ● This product requires the use of an iVac™ (S or E) connector

    The PeekSonic activation tip uses the same connector as the iVac™. For piezoelectric devices type S, use the Pac-Dent's iVac S-type connector (REF#9542SC). For piezoelectric devices type E, use the Pac-Dent's iVac E-type connector (REF#9542EC).

    Literature Summary

    Various techniques have been developed to enhance the cleaning of the apical part of the root canal. These techniques usually involve activating the irrigant using acoustic and hydrodynamic methods. Syringe irrigation alone may not be sufficient, but combining solutions and utilizing ultrasonic agitation can significantly improve the effectiveness of the irrigant.

Frequently Asked Questions

    Which type of activation, sonic or ultrasonic, is more effective for irrigants?

    Studies have shown that ultrasonic activation is more effective in removing dentin debris than sonic activation. This is due to the higher driving frequency of ultrasonics (29 kHz) compared to sonic devices (160-190 Hz), resulting in a higher flow velocity1,2. Moreover, the oscillation amplitude of the ultrasonic tip also increases with the flow velocity for a specific frequency. However, the diameter of the apical root

    canal is smaller than 0.5 mm, while the oscillation amplitude of the sonically activated tip in water is approximately 1 mm. This extensive wall contact between the tip and the root canal wall reduces the efficient streaming of the irrigant, inhibiting free oscillation of the sonic tip and consequently reducing the activation of the irrigant. Furthermore, cavitation was shown to occur in ultrasonic activation at clinically relevant ultrasonic power settings in both straight and curved canals but not around sonically oscillating tips3.

    Can a curved canal obstruct ultrasonic activation of the fluid?

    Cleaning the apical root canal can be challenging due to its complex anatomy. The canal's small dimensions and intricate structure can obstruct the flow of irrigants, making it challenging to clean1. Additionally, root canals often have curvatures that can reduce various irrigation techniques' effectiveness2, 3.

    In syringe irrigation, severe root canal curvatures mainly affect the cleaning effectiveness4. On the other hand, in ultrasonically activated irrigation, the penetration of the irrigant is influenced by the intensity of the ultrasonic waves5 and the distance between the file tip apex and the curved root canal. Interestingly, the curvature does not affect the flow depth, indicating that microstreaming occurs on a much smaller scale than the curvature itself. This suggests that the extent of cleaning in curved canals is comparable to that in straight canals.

    According to research studies, an ultrasonically oscillating tip effectively removes dentin debris from the root canal wall up to 3 mm in front of the file tip. The flow is observed to be correlated with this finding. Additionally, irrigant flow is unaffected by the root canal's curvature6.

    Has ultrasonic power influenced the cleaning capacity?

    The apical third of the root canal system is challenging to clean because of the complexity of the root canal morphology, making irrigant delivery and activation less effective1. The intensity of ultrasonic activation, adjusted by the power setting on the ultrasonic device, influences the energy transmission from the oscillating tip to the irrigant. It has been suggested that the velocity of the acoustic streaming occurring around oscillating tips is directly influenced by factors such as the intensity of the generator and its location on the tip2. A study showed that the cleaning efficacy was enhanced when the ultrasonic intensity rose, especially at the highest intensity3.
