Overview

oSIST prEN ISO 7260:2026:2026 – Dentistry - Protective filtering devices intended for use with powered polymerization activators – is a comprehensive standard developed by CEN and ISO for the dental sector. This international standard specifies the requirements, test methods, and labeling for protective filtering devices designed to reduce retinal blue light exposure when using powered polymerization activators such as quartz-tungsten halogen lamps and LEDs, as described in ISO 10650:2018. It provides guidance on performance, construction, and instructions for both eyewear and filters used in dental procedures involving light-curing technologies. The standard does not address protective devices for lasers or plasma arc sources.

Key Topics

• Blue-Light Hazard Mitigation: Defines limits for blue-light weighted transmittance (380 nm to 550 nm) to help prevent photochemically induced retinal injuries for both patients and dental staff.
• Types of Protective Devices: Covers requirements for protective filtering eyewear, handheld protective filters, and filters attached to polymerization devices.
• Construction and Quality: Sets specifications for area protected, material and surface quality, field of view, and resistance to cleaning and disinfection protocols.
• Testing Methods: Outlines standardized laboratory procedures for measuring spectral transmittance using spectrophotometric equipment, verification of apparatus accuracy, and protocols for validating filter performance.
• Labeling and Documentation: Lists mandatory markings such as model number, manufacturer identification, and compliance with relevant standards, ensuring traceability and proper usage.
• Packaging and Instructions: Details necessary packaging practices and the essential information to be included with instructions for use, such as cleaning procedures and warnings regarding improper use.

Applications

The oSIST prEN ISO 7260:2026:2026 standard is crucial for:

• Dental Clinics: Ensuring the safety of both practitioners and patients during procedures that utilize powered polymerization activators for curing resin-based materials (fillings, cements, sealants, etc.).
• Dental Equipment Manufacturers: Guiding the design, production, and quality assurance of filtering eyewear and shields to comply with blue light safety requirements.
• Regulatory Compliance: Offering a harmonized reference for authorities requiring conformity of personal protective equipment (PPE) in dental environments.
• Healthcare Providers: Supporting oral healthcare professionals in selecting and maintaining appropriate protective filtering devices to minimize occupational hazard from blue light exposure.
• Procurement and Safety Officers: Assisting in the specification, evaluation, and approval of compliant safety products for dental practices.

• ICNIRP Guidelines – Limits of exposure to incoherent visible and infrared radiation

Practical Value

By implementing oSIST prEN ISO 7260:2026:2026, dental practices and manufacturers ensure essential protection from the well-documented risks of blue light exposure during polymerization processes. This standard delivers robust, evidence-based guidance for the evaluation and selection of PPE, helps lower the incidence of eye injuries, enhances workplace safety, and ensures compliance with international dental equipment safety regulations.

Introduction
Light emitted from powered polymerization activators may exceed limit values for photochemical retinal
exposure to visible (blue) light under certain circumstances. Exposure limit values are specified in ICNIRP
[1]
Guidelines on limits of exposure to incoherent visible and infrared radiation and applied in IEC 62471 .
The spectral emission of powered polymerization activators typically overlaps substantially with the blue-
light hazard function for induction of retinal damage (peak interval between 435 nm and 440 nm). Most
powered polymerization activators have emission spectra that match the absorbance spectrum of the
photoinitiator camphorquinone, characterized by an absorption maximum of 468 nm. Some curing lights
have more than one emission peak to match the absorption of other photoinitiators in the wavelength range
approximately from 380 nm to 420 nm.
Powered polymerization activators have relatively small emission surfaces, typically 5 mm to 12 mm
diameter, and high radiance values, up to 3000 times higher than that of LED sources for indoor lighting. The
combination of the spectral emission, high power and small size of powered polymerization activators poses
a risk of exceeding the limits specified for retinal blue light exposure.
Both patients and oral healthcare providers may be exposed to visible light from powered polymerization
activators. Exposure may be either direct or indirect (i.e. reflected or scattered).
Protective filtering devices intended for use with powered polymerization activators can mitigate the retinal
blue-light hazard exposure by attenuating the light in the wavelength range of concern. Such protective
filtering devices can be in the form of protective filtering eyewear, handheld protective filters or protective
filters attached to powered polymerization activators.
