Influence of white mineral trioxide aggregate on inflammatory cells before and after expiry date.
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...

Objective: The aim of this study is to measure the effect of different condensation pressure on the microleakage of Mineral Trioxide Aggregate (MTA). Methods: This study was an invitro study. A total of 55 single rooted straight-canal human extracted sound teeth free of cracks or calcification were selected. Teeth were sectioned from CEJ region at 3 mm above the root apex. Remaining specimens ...
متن کاملOsteoblastic Cytokine Response to Gray and White Mineral Trioxide Aggregate
INTRODUCTION The materials used for root-end filling and perforation repair are in direct contact with live tissues e.g. bone and connective tissue; their effects however, are uncertain. The aim of this ex vivostudy was to evaluate the osteoblastic secretory activity adjacent to gray and white mineral trioxide aggregate (MTA) and Intermediate Restorative Material (IRM). MATERIALS AND METHODS ...
متن کاملRemoval of White Mineral Trioxide Aggregate Cement: A Promising Approach
Removal of MTA from dentin by applying 37% hydrochloric acid (HCl) to reduce microhardness and push-out bond strength. Forty dentin slices were filled with WMTA and divided into two groups (n = 20). Ten slices remained untreated while others were exposed to either HCl or phosphate buffer saline (PBS) and all samples were subjected to pushout test. The mode of bond failures was determined by SEM...
