OBJECTIVE: To compare the clinical outcome between mineral trioxide aggregate apical plug and mineral trioxide monoblock technique of endodontic apexification procedure of non vital permanent incisors with open apexes. STUDY DESIGN: Clinical in vivo Cross sectional comparative study PLACE AND DURATION: Endodontic department/College of Dentistry Ziauddin University, Karachi. Study duration was f...

introduction: the aim of the present investigation was to compare the efficacy of mineral trioxide aggregate (mta) and 0.2% chlorhexidine (chx) mixture to pure mta, as a pulp capping material. methods and materials: the pulp of 24 lateral incisors and canines from four dogs were exposed and capped either with mta or mta+0.2% chx. after 2 months the animals were sacrificed and the teeth were pre...

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: mineral trioxide aggregate (mta) has been suggested for root-end filling, vital pulp therapy, apical plug, perforations repair, and root canal filling. since the introduction of mta in 1993, many studies about this material have been published. the aim of this survey was to illustrate statistical information about published articles in pubmed-index journals vis-à-vis the various a...

external inflammatory root resorption (eir) represents a challenge in endodontic practice. eir commonly occurs after dental trauma that results in periodontal ligament injury, pulp necrosis and subsequent infection.  treatment of eir is based on disinfecting the root canal system through chemomechanical procedures and then filling it with calcium hydroxide or triple antibiotic paste. dental tra...

introduction: mineral trioxide aggregate (mta) as an alternative material to gutta-percha for obturation of root canal in special cases has several drawbacks. the purpose of this study was to compare the apical sealing ability of a new mta-based sealer versus mta. materials and methods: a total of 36 canals of extracted maxillary central incisors were instrumented and randomly divided into 3 ex...

Pulp capping and pulpotomy procedures were performed on 15 male mongrel dogs. Three materials were used: calcium hydroxide, acid-etched dentin bonding, and mineral trioxide aggregate. Six of the animals were killed at 50 days and nine were killed at 150 days. Samples from 11 dogs were used for histological evaluation, and the remaining dog samples were used for scanning electron microscopy eval...

AIM To analyse the physicochemical properties of a Nano white mineral trioxide aggregate (NWMTA) and compare it with white mineral trioxide aggregate (WMTA). METHODOLOGY White mineral trioxide aggregate and NWMTA were prepared and mixed according to the manufacturer's instructions. Surface area of powder before hydration, setting time, X-ray diffraction and microhardness at pH values of 4.4 a...

Aim: The aim of this study was to compare the effect of an acidic and alkaline environment on the compressive strength of Grey Pro Root Mineral Trioxide Aggregate and Biodentine. Methodology: A total of eightyhuman, mandibular molars were used. Perforations were made in the furcation of each molar and enlarged to #3 Pesso drills. The repair was performed, according to the materials used. Sample...
