The effectiveness of opaquer and color-modifier materials: a laboratory study
Journal of the American Dental Association (1939)
|February 1, 1987
Summary
New dental composite resins offer improved masking for stained teeth in esthetic dentistry. This study evaluated 57 opaquers and color modifiers, finding a range of effectiveness from minimal to excellent stain coverage.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
- Esthetic Dentistry
Background:
- Direct bonding composite resins are increasingly utilized in esthetic and restorative dental procedures.
- The demand for materials with effective stain-masking properties is significant for achieving predictable esthetic outcomes.
Purpose of the Study:
- To evaluate the stain-masking effectiveness of various opaquers and color modifiers used with direct bonding composite resins.
- To provide data on the performance of different masking materials for restorative dental applications.
Main Methods:
- An in vitro study design was employed.
- A total of 57 different opaquers or color modifiers were tested.
- Effectiveness was assessed on 265 prepared specimens to evaluate stain concealment capabilities.
Main Results:
- The tested opaquers and color modifiers demonstrated a spectrum of stain-masking effectiveness.
- Results ranged from minimal to excellent concealment of underlying stains across the evaluated materials.
- Variability in performance suggests material-specific properties influence masking ability.
Conclusions:
- Direct bonding composite resins with opaquers/color modifiers offer viable solutions for masking dental stains.
- The effectiveness of stain masking varies significantly among available products.
- Clinicians should consider material-specific performance data when selecting products for esthetic and restorative procedures.
