Color Stability of Different Restorative Approaches for the Masking of Silver Diamine Fluoride after Thermal Aging.

Aim: The present study aims to evaluate the color stability of different masking modalities of silver diamine fluoride (SDF) on extracted carious teeth after thermal aging.

Methods and results: One hundred and eight recently extracted carious permanent teeth were used. All sample teeth had SDF applied over the carious lesion. The teeth were then divided into six groups: group A (SDF, potassium iodide (KI), and packable composite resin), group B (SDF, flowable, and packable composite resin), group C (SDF, KI, resin-modified glass ionomer (RMGI), and packable composite resin), group D (SDF, KI, and RMGI), group E (SDF, hybrid glass ionomer (HGI), packable composite resin), and group F (SDF and RMGI). VITA Easyshade was used to evaluate color stability. Initial masking of the dark staining was improved in groups in curing light groups (groups D and F). Groups restored with RMGI demonstrated the greatest color changes after aging. The groups that showed the greatest color stability of the materials after 5 years of aging were groups A, B, and E. Highest color change was observed during the first clinical year for all groups.

Conclusion: KI is effective at reducing SDF staining. Composite (CMP) provides a long-term color-stable restoration. Thermocycling had the greatest effect on HGI restorations.

Clinical relevance: One of restorative dentistry's most important clinical parameters is the color stability of tooth-colored dental restorations. Choosing a suitable restorative material is essential to overcome SDF's staining effects. Applying KI and composite resin restoration was the most effective, long-term color-stable restorative material for masking the SDF staining.
