- Abstract
Though since it's appearance on market in 1993 hundreds of studies and experiments were made regarding on it's chemical and physical properties, sealing abilitiy, antibacterial activity, leakage, and biocompatibility of MTA, scanning electronmicroscope (SEM) studies made on MTA-pulp interface, are very rare. Multiple analyses discussed the use of MTA as direct capping material. These reports have shown that MTA is a promising material for the preservation of pulp tissue when used as a direct capping material. For the investigations there have been used 4 molars that had been extracted for orthodontic purposes 6, respectively 30 days after treatment with MTA. After extraction, the tooth has been cut at the cement-enamel junction. For scanning electron microscopy examination (SEM), after eviction of the pulp, the teeth has been cut, following a longitudinal, sagittal, mezio-distal section from the crown in apical direction, passing through the middle of the area treated with MTA. Then the samples were processed according to electron microscopy (SEM) techniques, and observed with the Jeol JEM 1010 type scanning electron microscope. The images were captured with Megaview III digital camera. The images taken 30 days after the treatment with MTA prove that odontoblasts and fibroblasts are in an intense synthesis activity. Predentine is disposed in a considerable layer, while odontoblasts' extensions are pierceing it through heading towards the capping agent.
