- Abstract
- Two carrier-based materials were compared to assess their resistance to coronal microleakage in a dog model when no coronal seal was present. Histologic evidence of inflammation and infection were the outcome parameters used. Experimental teeth were filled with carrier-based Resilon® (Epiphany®, n=25) or with carrier-based gutta-percha (Thermafil®, n=25) and were left exposed for four months. One control group received a coronal seal over Epiphany® or Thermafil® root fillings. A second control group was instrumented and left empty. There was a higher frequency of inflamed teeth in the Thermafil® group (29%) than in the Epiphany® group (9%). 2 of 22 Epiphany® filled teeth (9%) showed evidence of tubular infection, whereas 16 of 23 Thermafil® filled teeth (70%) were infected. The difference in infection rates between Epiphany® and Thermafil® was statistically significant (p< 0.001).
