Popis: | This study compared the biocompatibility of two new calcium phosphate-based root canal sealers (CAPSEAL I, CAPSEAL II) with another type of commercially available calcium phosphate sealer (Apatite Root Sealer type I, Apatite Root Sealer type II) and a zinc oxide eugenol-based sealer (Pulp Canal Sealer EWT) after implanting them in the subcutaneous tissue of rats. After 1, 2, 4, and 12 weeks, the tubes were removed with the surrounding tissues. The tissue reactions were graded as being mild or 1, moderate or 2, and severe or 3 after a histopathological examination. The results were analyzed statistically with the Kruskal-Wallis test. The biocompatibility of the materials was interpreted according to the Federation Dentaire Internationale criteria (1980). The inflammatory reactions decreased with time. The new sealers showed a lower tissue response than any of the other sealers in all the experimental periods. All the tested sealers showed an acceptable biocompatibility. |
