This blog explores how curing light positioning can affect polymerisation, and how Kerr’s Demi Pro can improve access and control – even in harder-to-reach areas – with its flexible design that moves with the user.

Key Takeaways:

  • Increasing the distance between the curing light tip and the restoration can reduce the irradiance reaching the target.
  • Posterior teeth, deep preparations, and difficult angles can make it harder to maintain effective curing light positioning.
  • Good manoeuvrability can help clinicians position the curing light more effectively in harder-to-access areas.
  • The Kerr Demi Pro features a 360° rotating, low-profile tip designed to improve access and freedom of movement.
  • Its lightweight, balanced design supports comfortable handling, while collimated light output helps to maintain consistent performance at clinical distances.
  • A built-in radiometer, Periodic Level Shift Technology, and optional transillumination tip provide additional support throughout the restorative workflow.

The Real-World Challenge Of Inadequate Movement While Curing

In an ideal setting, your curing light should always be positioned close to the restoration, and perpendicular to its surface. But posterior teeth, deep preparations, and difficult angles can make it harder to maintain the right position throughout treatment – meaning real-world conditions are often far less straightforward.

Reaching hard-to-access areas may require significant adjustments to your hand, wrist, or body positioning, which can affect more than just your comfort.

If restricted access forces your light further away or off-angle, less energy may reach the restorative material, resulting in inadequate polymerisation. In turn, this can adversely affect the physical and mechanical properties of resin-based composites, potentially resulting in problems such as reduced hardness, weaker material properties, and increased microleakage.

For these reasons, good curing technique requires good manoeuvrability. But could your current curing light be making that harder than it needs to be?

Kerr Demi Pro: The Dental Curing Light That Moves With You

Designed to give you greater freedom of movement while curing, the Kerr Demi Pro combines a lightweight, ergonomic design with a unique 360° rotating, low-profile tip to help you reach harder-to-access areas with greater ease.

And with consistent curing performance at clinical distances, it gives you the flexibility to work around the treatment, without compromising on control.

Rather than having to continually adjust your position to accommodate your curing light, the Demi Pro is designed to give you more flexibility to move around the treatment area, with a tip that can be repositioned to suit your needs, helping you maintain access and control even when space is limited.

FAQs

As the distance between the curing light tip and the restoration increases, the amount of light reaching the restorative material can decrease. This can make effective polymerisation more difficult, particularly where access is restricted.
Where possible, the curing light tip should be positioned close to the restoration, and perpendicular to its surface to support effective light delivery.
Posterior teeth can be more difficult to access because of limited space, deeper preparations, and challenging angles, which can make it harder to maintain the desired curing light position throughout treatment.
A low-profile, manoeuvrable curing tip can make it easier to position the light in harder-to-reach areas. Kerr Demi Pro uses a 360° rotating, low-profile tip to support greater freedom of movement and access.
Alongside curing performance, features such as manoeuvrability, tip design, weight, ergonomics, and the ability to check light output can all support day-to-day use. The Kerr Demi Pro combines a rotating low-profile tip, 115g balanced design, collimated light output, and a built-in radiometer for ease of use and optimal manoeuvrability.
