Summary
At-home bleaching can alter tooth enamel and restorative materials. This review examines how whitening systems impact bond strength, color, and integrity of dental restorations.
Area of Science:
- Dentistry
- Dental Materials Science
Background:
- At-home bleaching is a popular cosmetic dental procedure.
- Understanding its effects on dental restorations is crucial for clinical practice.
Purpose of the Study:
- To review the effects of at-home bleaching agents on dental restorative materials.
- To analyze the impact on enamel surfaces, bond strength, marginal integrity, and color.
Main Methods:
- Literature review of studies investigating at-home bleaching effects.
- Analysis of research on various dental restorative materials (e.g., composites, adhesives).
Main Results:
- Bleaching agents can negatively affect the surface and mechanical properties of some restorative materials.
- Potential for reduced bond strength and compromised marginal integrity of restorations.
- Changes in the color of restorative materials may occur.
Conclusions:
- Clinicians should be aware of the potential adverse effects of at-home bleaching on dental restorations.
- Further research is needed to develop bleaching-resistant restorative materials and protocols.
