How it works

Most modern dental composites and resin adhesives are fluorescent due to its content of fluorophores. Under certain wavelengths of illumination (UV-A 395 to 400nm), these materials can be distinguished from tooth tissue. Therefore, significantly reducing risk of iatrogenic tooth damage when they need to be removed. The K-Lite is a groundbreaking dental device that allows in any dental discipline its appropriate indication

"It may seem easy to give good review of my own product but the truth is that K-lite was created due to the necessity of seeing beyond the limits of my eyes"

Katherine Losada

"The K-Lite is this clever lightweight instrument you can use with such great ease, that is why I love it. Its small tip makes it very agile and easy to use in all areas of the mouth.The Violet Mode helps me to diagnose active caries. The White-Light Mode is extremely useful to visualize cracks and inter-proximal caries"

"Dentists tend to buy a large number of things that we rarely use, however, this is a tool that far from being trendy, is really useful (...) I used to think during my practices that I was removing all excess residual material, nowadays I have realized I wasn't! I was unable to fully see it, K-lite has made it visible"

Alejandro Pineda

Frequently Asked Questions

General / Order & Delivery


Why should I have K-lite in my dental clinic? 

You may need K-lite in your dental clinic if you care about dental tissue preservation, if you look for a  minimally invasive practice saving time with a contactless minimal invasive diagnostic method and want to add value to your daily practice through technology

Why is K-lite an Eco-Friendly Device? 

The technology inside uses premium semiconductor integrated circuits, achieving high accuracy (<1%) of both intensity and wavelength (color) of the two LEDs independently. In addition, it offers an embedded microprocessor for controlling the soft-start feature, increasing dramatically the lifetime of the two AAA batteries and achieving a power efficiency (of above 95%) when operated in normal conditions. Moreover, K-Lite features a smart timing auto-stop (after 10 s and 30 s respectively) which further increases its energy efficiency. Hence, the K-Lite product is practical, easy to use, and green for the environment. These features confer more flexibility and sustainability in the dentistry industry

Why does the purple light flash every 10 seconds and after 30 seconds it goes off?

The violet light is of the UVA type in an intensity controlled by a mini software to imitate the human eye blink and protect us from the reflection of residual UV light on the dental surface. Each 10-second blink is used to: a) Indicate visual use time. b) Prevent heating of the LED that could cause damage due to its proximity to the pulp. and c) Save battery consumption
