In order to evaluate the biocompatibility and mineral repair capacity, mineral trioxide aggregate (MTA), portland cement normal setting (PCn) and fast setting (PCf) and calcium hydroxide-based paste (Calen) filled silicone tube were implanted into the dorsal subcutaneous connective tissues of 25 Wistar rats. Animals were euthanized at 24, 72 hours, 7, 15 and 30 days. Implants with surrounding tissues were fixed with 10% buffer formaldehyde and processed for histological routine techniques. Slides (5 µm serial cuts) were stained with H&E and Von Kossa stains for morphological, qualitative and quantitative analysis by light microscopy. Calen showed severe and moderate inflammatory response and granuloma-tous reaction with psammoma body-like formation. PCn and MTA have similar behavior, with mild inflammatory reaction from 8% and 4%, respectively. Even though, PCn and MTA demonstrated analogous biological reaction, MTA developing thick artificial mineral precipitation (p = 0,007). All sealers demonstrated a similar inflammatory response at all time periods studied (p = 0.678).
