statement of the problem when root perforation occurs in the middle third of the root, considerable canal length that would normally be available for post placement must be filled by the repair material, which necessitates placement of a considerably shorter post, leading to poor retention. purpose the aim of this study was to compare retention of titanium parapost luted with mta and four diffe...

Mineral trioxide aggregate is the mainstay of treatment of large internal resorption defects. But its cost may be a deterrent to its use in some patients. The present case report describes the successful endodontic management of an extensive internal resorptive lesion in a mandibular molar with metal reinforced glass ionomer cement.

OBJECTIVES This study aimed to evaluate the chemical and biological properties of fast-set white mineral trioxide aggregate (FS WMTA), which was WMTA combined with calcium chloride dihydrate (CaCl2·2H2O), compared to that of WMTA. MATERIALS AND METHODS Surface morphology, elemental, and phase analysis were examined using scanning electron microscope (SEM), energy dispersive X-ray microanalysi...

INTRODUCTION One of the uses of white mineral trioxide aggregate (MTA) is as an apical barrier in immature teeth. Although this treatment has been reported to have high success rates, a number of cases of discoloration have been noted. The aim of this research was to investigate the color stability of white MTA in contact with various solutions used in endodontics. METHODS The change in color...

Mineral trioxide aggregate (MTA) and Portland cement are being used in dentistry as root end-filling materials. However, biocompatibility data concerning genotoxicity and cytotoxicity are needed for complete risk assessment of these compounds. In the present study, genotoxic and cytotoxic effects of MTA and Portland cements were evaluated in vitro using the alkaline single cell gel (comet) assa...

INTRODUCTION A number of vital pulp therapy techniques have been recommended to preserve pulp vitality in teeth with complicated crown fractures, especially in young patients. Calcium hydroxide has been the gold standard as a pulp capping material, but recently mineral trioxide aggregate (MTA) has been recommended. This case report describes the treatment of tooth discoloration caused by white ...

INTRODUCTION The aim of this study was to compare the effect of subcutaneously implanted white mineral trioxide aggregate (WMTA) on inflammatory reactions before and after expiry date. METHODS Fifty Wistar rats were used in this study. Polyethylene tubes were filled with WMTA with expiry dates of 2008, 2009, and 2011, and empty ones serving as the controls were implanted into the subcutaneous...
