DMG Introduces New Clinical Protocols for Icon Resin Infiltration

---

Dental professionals across North America now have access to updated clinical protocols for micro-invasive Icon resin infiltration. These new protocols from DMG incorporate enhanced diagnostic techniques, optimized infiltration timing, and structured treatment guidance designed to improve predictability and outcomes for patients with early enamel lesions and opacities.

The updated approach is the result of DMG’s commitment to clinical research and integrates transillumination-based diagnosis, extended infiltration times, and new pre-treatment strategies, alongside a newly-developed clinical decision tree that helps guide dental professionals through case selection and treatment pathways.

Resin infiltration represents a cornerstone of modern minimally invasive dentistry, enabling clinicians to intervene early and preserve healthy tooth structure while addressing patients’ esthetic concerns.

With the addition of improved diagnostics, refined protocols, and structured clinical guidance, the updated Icon approach aims to help dental professionals achieve more predictable, conservative, and esthetic treatment outcomes.

Enhanced Diagnostic Protocol: Transillumination

One of the most significant updates to the clinical workflow is the incorporation of transillumination as a diagnostic and monitoring tool that improves case selection and reduces the risk of misdiagnosis or unnecessary invasive treatment. It is also helpful during treatment to assess lesion dehydration and infiltration progress.

This diagnostic enhancement allows practitioners to better differentiate:

• White spot enamel lesions and opacities
• Early carious lesions
• Developmental defects such as fluorosis

Optimized Infiltration Protocols

The updated protocol also emphasizes longer infiltration times, allowing deeper penetration of the low-viscosity resin into porous enamel.

“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, a recognized dental industry key opinion leader and 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.”

Longer infiltration periods can improve diffusion of the resin intohypomineralizedenamel structures, increasing the masking effect and enhancing lesion stabilization.

Expanded Pre-Treatment Strategies

The new protocols also incorporate pre-treatment methods designed to produce predictable, esthetic outcomes, including:

• Microabrasion to remove resistant enamel layers and improve access to the lesion body
• Pre-whitening or bleaching protocols in certain cases to reduce contrast between affectedand healthy enamel prior to infiltration

Introducing the Icon Clinical Decision Tree

To support clinicians in implementing these updated protocols, a new Icon Clinical Decision Tree has been introduced.The decision tree provides a structured pathway to help dental professionals:

• Evaluate lesion etiology and severity
• Determine whether infiltration is appropriate
• Identify when additional pre-treatment steps may be necessary
• Select the correct treatment protocol based on lesion characteristics

The tool simplifies clinical decision-making and promotes predictable treatment planning for whitespot lesions, fluorosis, and early caries lesions.

About Icon Resin Infiltration

Icon is a micro-invasive treatment 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, the technique arrests lesion progression and restores the natural optical properties of enamel.
