introduction : the aim of this quantitative systematic review/meta-analysis was to compare the treatment outcomes of mineral trioxide aggregate (mta) and calcium hydroxide (ch) in pulpotomy of human primary molars. the focused pico question was “in case of pulp exposure in vital primary molars, how does mta pulpotomy compare to ch in terms of clinical/radiographic success?” methods and material...

introduction : this in vitro study was designed to evaluate the effect of smear layer removal on push-out bond strength of white mineral trioxide aggregate (wmta) and calcium-enriched mixture cement (cem). materials and methods: dentin discs with 3 mm thicknesses were divided into 4 groups ( n =15): group 1: irrigation of the canal with normal saline and filling with wmta; group 2: irrigation w...

introduction : the aim of this in vitro study was to evaluate the effect of smear layer on the push-out bond strength of white mineral trioxide aggregate (wmta) with and without disodium hydrogen phosphate (na 2 hpo 4 ). materials and methods: dentin discs with standard cavities were obtained from extracted human single-rooted teeth and divided to 4 groups ( n =15) according to the irrigation r...

objective: one of the principle purposes of root canal obturation is to obtain hermetic sealing of the root canal system. according to the development of technology, many materials are now used in root canal filling. an in vitro dye leakage study was performed to evaluate the apical sealability of white-colored mineral trioxide aggregate (wmta) and gray-colored portland cement (gpc) when used a...

there is some concern that root resection may alter the seal of the previously set orthograde material. the aim of this study was to evaluate the apical sealing ability of orthograde mineral trioxide aggregate (mta) and calcium enriched mixture (cem) plugs after resection of the roots.the fluid filtration method was carried out on a total of 51 roots in three experimental (n=15) and two control...

BACKGROUND Regeneration of periodontal tissues is a major goal of periodontal therapy. Dental pulp stem cells (DPSCs) show mesenchymal cell properties with the potential for dental tissue engineering. Enamel matrix derivative (EMD) and platelet-derived growth factor (PDGF) are examples of materials that act as signaling molecules to enhance periodontal regeneration. Mineral trioxide aggregate (...

INTRODUCTION Pulp revascularization may be considered a promising alternative for necrotic immature teeth. Many studies have accomplished passive decontamination associated with an antibiotic paste. To date, there is no report evaluating calcium hydroxide associated with 2% chlorhexidine gel for revascularization therapy. The aim of this case report was to describe a new proposal for pulp revas...
