After resin infiltration in ICON treatment, what finishing step is essential?

• A. Polishing and ongoing monitoring
• B. Immediate extraction
• C. Full composite crown
• D. No further steps needed

Answer: (A)

Polishing the infiltrated enamel surface and ongoing monitoring are essential after ICON resin infiltration. Finishing with polishing removes any residual resin and smooths the treated area, which improves aesthetics, reduces surface roughness that can attract plaque, and helps the tooth wear naturally without rough spots. Ongoing monitoring is needed because resin infiltration aims to arrest caries progression, but the patient remains at risk for new lesions or reactivation if oral hygiene or caries risk factors aren’t controlled. Regular follow-up allows clinicians to assess lesion stability, check for marginal integrity or discoloration, and reinforce conservation of tooth structure. Immediate extraction, a full crown, or no further steps aren’t appropriate here because they don’t provide the finishing touch or the essential surveillance that supports long-term success.
