DMG has announced that dental professionals across North America now have access to updated clinical protocols for micro-invasive Icon resin infiltration. The revised protocols incorporate enhanced diagnostic techniques, adjusted infiltration timing, and structured treatment guidance intended to improve predictability and clinical outcomes for early enamel lesions and opacities.
The updated approach integrates transillumination-based diagnosis, extended infiltration times, and new pre-treatment strategies. It also introduces a clinical decision tree designed to guide clinicians through case selection and treatment pathways. The decision tree is available at https://drilling-no-thanks.info/wp-content/uploads/2026/02/DMGA_Icon_Decision-Tree_2026.pdf.
Resin infiltration is used in minimally invasive dentistry to address early enamel caries and esthetic concerns while preserving tooth structure. According to DMG, the revised protocols aim to support more consistent and conservative treatment outcomes through improved diagnostics and structured clinical guidance.
One of the primary changes is the incorporation of transillumination as part of the diagnostic and monitoring process. This method supports more accurate case selection and helps reduce misdiagnosis or unnecessary invasive procedures. It can also be used during treatment to assess lesion dehydration and monitor infiltration progress. The approach assists clinicians in differentiating between white spot enamel lesions and opacities, early carious lesions, and developmental defects such as fluorosis.
The updated protocols also emphasize longer infiltration times. According to the company, extended application allows deeper penetration of low-viscosity resin into porous enamel, which may improve diffusion into hypomineralized structures and enhance both lesion stabilization and masking effects.
“Over the years, I’ve found that success with Icon resin infiltration isn’t just about the material—it’s about refining the protocol,” said Dr. David Rice, founder of igniteDDS. “By incorporating transillumination for better diagnosis and allowing more time for resin penetration, we’re seeing more predictable outcomes and significantly improved esthetic results. It’s a meaningful step forward in how we manage white spot lesions without drilling.”
Additional updates include expanded pre-treatment strategies, according to the company. These include microabrasion to remove resistant enamel layers and improve access to lesion bodies, as well as pre-whitening or bleaching in certain cases to reduce contrast between affected and healthy enamel before infiltration.
The clinical decision tree introduced with the protocols provides a structured framework to evaluate lesion etiology and severity, determine the suitability of infiltration, identify when pre-treatment is needed, and select appropriate treatment protocols based on lesion characteristics. The tool is intended to support clinical decision-making for white spot lesions, fluorosis, and early caries lesions.
Icon resin infiltration is designed to halt early enamel caries and improve the appearance of white spot lesions without drilling by infiltrating a low-viscosity resin into the lesion body. According to DMG, this process arrests lesion progression and restores the optical properties of enamel.
DMG manufactures and distributes dental materials and equipment, including products such as Luxatemp, LuxaCore Z Dual, LuxaCrown, Ecosite restorative composites, and the DentaMile 3D printing system. Its product portfolio is intended to support workflows for dental and laboratory professionals.
