background and aims. biocompatibility of root-end filling materials is a matter of debate. the aim of this study was to compare the biocompatibility of a variety of commercial proroot wmta cements and a resin-based cement (geristore®) with different ph values of setting reaction and different aluminum contents, implanted into the subcutaneous connective tissue of rats at various time intervals....

Introduction: Cervical root resorption is one of the most important complications of intra coronal bleaching. A way of preventing this type of resorption is using a coronal barrier under the bleaching materials. The aim of this study was to compare the sealing ability of glass ionomer cement and Pro Root Mineral Trioxide Aggregate (MTA) as a coronal barrier in intra coronal bleaching. Materi...

INTRODUCTION Various materials are used in direct dental pulp capping method. Their biocompatibility and alkalizing abilities are of primary importance affecting therapeutic effects. The aim of this study was to evaluate and compare the cytotoxicity of various pulp-capping materials on human gingival fibroblasts and investigate the pH changes induced by these materials. MATERIAL AND METHODS H...

introduction: solubility of mineral trioxide aggregate (mta) is an important characteristic that affects other properties such as microleakage and biocompatibility. distilled water (dw) has previously been used for solubility tests. this experimental study compared the solubility of mta in dw, synthetic tissue fluid (stf) and new simulated plasma (sp). methods and materials: in this study, 36 s...

introduction: this in vitro study compared the cytotoxic effects of three commercially available mta formulations naming proroot mta (pmta), angelus mta (amta), and root mta (rmta), with calcium-enriched mixture (cem) cement and a new nanohybrid mta (nmta) on human dental pulp stem cells (dpsc). methods and materials: four disc-shaped specimens of each material were prepared. after completion o...

i ntroduction: the aim of this study was to evaluate the clinical and histological status of the pulp in sound human premolars after direct pulp capping (dpc) with four different dpc methods/materials. methods and materials: this study was conducted on eight volunteers who had to extract four first premolars due to orthodontic treatment. subsequent to tooth isolation, standardized class i occlu...

INTRODUCTION Endodontic surgery is a valuable option for maintaining patient's natural dentition when previous orthograde endodontic treatments fail to succeed. Proper root-end preparation and placement of a retro-filling material are recommended for successful endodontic surgery. The objective of this experimental study was to compare sealing ability of Resilon/Epiphany system, as a potential ...

INTRODUCTION It has been documented that total removal of carious dentin, assessed according to clinical criteria, does not mean complete eradication of bacteria. For that reason in prevention of caries and pulp inflammations, application of the materials having high antibacterial properties seems to be indispensable. AIM Determination of antibacterial activities of two white Mineral Trioxide...

INTRODUCTION The provision of an effective apical seal is an essential factor when choosing an appropriate material for success of root-end surgeries. Root-end resection, preparation and obturation should provide an adequate apical seal. The aim of this in vitro study was to investigate bacterial and dye microleakage of four different root-end filling materials and compare the efficacy of these...
