Setting of mineral trioxide aggregate (MTA) is affected by various factors. The purpose this in vitro study was to evaluate the influence root canal wall thickness on mechanical properties MTA along whole apical plug. Bovine bone mold tubes with internal diameter 2 mm, height 5 and 0.8 1.2 1.6 mm were filled 3 ProRoot kept 37 °C relative humidity 100% for 7 days. indentation hardness reduced mo...

The histologic response to intentional perforation in the furcations of 28 mandibular premolars in seven dogs was investigated. In half the teeth, the perforations were repaired immediately with either amalgam or mineral trioxide aggregate; in the rest the perforations were left open to salivary contamination before repair. All repaired perforations were left for 4 months before histologic exam...

This study characterized the interactions of mineral trioxide aggregate with a synthetic tissue fluid composed of a neutral phosphate buffer saline solution and root canal dentin in extracted human teeth using inductively coupled plasma-atomic emission spectroscopy, scanning electron microscopy, energy dispersive X-ray analysis, and X-ray diffraction. Mineral trioxide aggregate exposed to synth...

This study evaluated tristrontium aluminate (S3A) and its viability as a component for tricalcium silicate (C3S) cements. The properties of S3A, C3S, S3A/C3S mixtures were in terms setting time, compressive strength, flowability, radiopacity. X-ray diffraction (XRD) pattern verified the powder synthesized laboratory consequently, confirming preparation method. S3A exhibited lowest followed by C...

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...

Objectives: The aim of the study was to evaluate clinical success mineral trioxide aggregate (MTA) partial pulpotomy as a definitive procedure in deeply carious permanent posterior teeth using 0.12% chlorhexidine (CHX) gluconate or normal saline hemostatic agents. Materials and Methods: A pilot randomized control trial conducted on subjects with deep lesion 20 immature (10.8 ± 2.62 years). Cari...

The purpose of treating furcal perforation is to seal the artificial communication between canal space and periradicular tissue prevent periodontal breakdown. duration, size location were identified as primary prognostic factors for determining successful treatment. Mineral trioxide aggregate (MTA) has been regarded an ideal material repair owing its excellent sealability biocompatibility. pres...
