- Abstract
- The purpose of this study was to investigate biological tissue reactions to various restorative dental materials.
An experimental pellects was implanted into subdermal tissue in dog subjects observing 1 week, 3 weeks, and 8 weeks respectively. The obtained histo-pathological findings were as follows:
1. Experimental pellets such as gold, ticonium and amalgam alloy are considered biologically acceptable.
2. Experimental results in 1 week dog showed acute inflammatory changes.
3. Experimental results in 8 week dog showed fibrotic and chronic inflammatory changes.
4. Active irritans such as silicate cements revealed acute inflammatory changes in all observed period.
5. Biological tissue to irritants observed.
