Abstract
|
|
|
Composite resin restorations are widely used to restore decayed teeth or preventive restoration in children. Children often receive topical fluoride treatments on a semiannual basis. However there is concern that topical acidulated phosphate fluorides (APF) may cause deterioration of composite resins. The aim of this study was to evaluate the surface changes in composite resins due to topical fluoride application. Composite resins(Solitaire 2 {(R)}, Metafil CX {(R)}, Composan LCM {(R)}, Charmseal {(R)}) in topical fluoride agents were immersed and their surface roughness, weight loss and SEM findings were evaluated.
The results were as follows:
1. The 4 minutes-immersion group showed more roughened surface than 1 minute-immersion group and the control group showed the smoothest surface among all the materials, and there was statistically significant difference between the groups except the Composan LCM {(R)} (P<0.05).
2. There was no significant difference between the 1 minute-immersion group and 4 minutes-immersion group in weight loss (P>0.05).
3. The experimental group treated with topical fluoride gel showed generally more roughened surface than control group in the SEM findings.
