introduction: biocompatibility is a desirable feature for root-end filling materials. in this study we aimed to compare a new material called cold ceramic (cc) with intermediate restorative material (irm) and mineral trioxide aggregate (mta) using methyl-tetrazolium bromide (mtt) assay. materials and methods: the materials were tested in fresh and set states: (n=108). the cytotoxicity was compa...

Background: The quality of the coronal seal of root canal filling material is important for periapical health. Absorption of water or saliva by the temporary restorative materials leads to dimensional changes, loss of retention, staining and breaking in margin contours. Hence this study was carried out to evaluate and compare the sealing properties, water absorption and solubility of IRM (inter...

the aim of this study was to evaluate the marginal adaptation of biodentine in comparison with mineral trioxide aggregate (mta) and intermediate restorative material (irm), as a root end filling material, using scanning electron microscopy (sem).thirty permanent maxillary central incisors were chemo-mechanically prepared and obturated. three millimetres of the root end were resected and 3mm ret...

introduction:  this  in vitro  study compared the apical sealing ability of three common root end filling materials namely mineral trioxide aggregate (mta), intermediate restorative material (irm) and calcium-enriched mixture (cem) cement using a bacterial leakage model.  methods and materials: the study was conducted on 83 single-rooted human teeth. tooth crowns were cut and root canals were p...

There are various restorative materials have been used in dentistry. Among all these restorative materials each and every material will have their own beneficial effects and harmful effects. The primary objective of this review is to evaluate the pulpal responses and the cytotoxic effects of various restorative materials used in operative and restorative dentistry. Understanding the biocompatib...
