Factors influencing the colour stability of ceramic veneers: A systematic review
| Summary: | Introduction: Maintaining long-term aesthetic success of ceramic veneers is depending on understanding the factors contributing to color stability. Objectives: To investigate the factors that may influence the long term colour stability of ceramic veneers. Materials and method: This systematic review was conducted in the PubMed database. It was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA),2020 . Results: Of the 70 studies found in this search, only 18 met the inclusion criteria. 60% of the studies included in this systematic review received a strong rating for quality assessment. Colour changes in ceramic veneers can be caused by intrinsic and/or extrinsic factors that compromise aesthetic results. Discussion: There is a consensus that intrinsic factors such as the thickness of the ceramic, the composition of the resin cement, the mode of polymerization and extrinsic factors such as colouring due to staining by absorption of colorants from exogenous sources can influence the colour variation of ceramic veneers. Conclusion: For long term colour stability of ceramic veneers, the degree of conversion and polymerization efficiency are more significant than the choice between the dual and light modes of polymerization. The included photo-initiator system is a factor a clinician needs to be aware of while using light mode. It is also advised to photoactivate dental adhesive beforehand. In addition, resin cements combining Ivocerin and TPO demonstrated increased colour stability. |
