Lares Research has released an innovative new handpiece technology called Fluoresce™ HD, according to a September 19, 2025, press release from the company. The technology aids in the visualization of decay and old composites by adding a second 405 nm (near UV) light output to dentists’ existing highspeed handpieces and electric contra angles. When the Fluoresce HD near UV light is activated, it turns the mouth into a color-coded map with healthy tooth structure, decay, and composite materials all appearing in different colors.
Fluoresce HD causes healthy tooth material to appear light green, but due to the presence of porphyrins in live caries-causing bacteria, it causes decay to appear bright red. This improves caries visualization, which may help clinicians be more conservative in their preparations, increase their confidence in complete caries removal, and save chair time by reducing the need for probing, dyes, and imaging. The benefits are similar for composite removal. Because Fluoresce HD causes most old composites to appear bright white against light green background of healthy tooth structure, it improves visualization, helping clinicians to achieve complete composite removal while remaining minimally invasive.
The patented Fluoresce HD dual wavelength LED swivel coupler, which does not require the purchase of new fiber optic handpieces and is Kavo MULTIflex* compatible, allows clinicians to switch between white or near UV light output with the push of a button. And with the patent pending Smoothdrive™ Dual Wavelength Electric Motor System, which is compatible with all leading brand and model fiber optic contra angles and does not require the purchase of new contra angles, clinicians can switch between the white and near UV light output by depressing a button on a smartphone application.
To purchase Fluoresce HD products, or any of the company’s exceptional handpieces, call Lares Research factory direct at 888-333-8440 (Ext. 1) or visit the company’s website.
