This case series aims to comprehensively introduce intentional replantation with a focus on its indications and case selection in endodontics. In all represented cases, calcium enriched mixture (CEM) cement is used for root-end filling. This case series demonstrates twenty cases of IR and extraoral root-end resection and filling with CEM cement. All the selected teeth had a failed endodontic tr...

The purpose of this study was to compare the sealing ability of gray mineral trioxide aggregate (GMTA), white MTA (WMTA), and both white and gray Portland cement as furcation perforation repair materials. A total of 120 human mandibular first molars were used. After root canal obturation and preparation of furcal perforations the specimens were randomly divided into four groups of 25 teeth each...

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...

Tricalcium-silicate and Tetracalcium-phosphate were prepared from ultra-pure chemical compounds via solid-state reaction at 1450 o C and 1500 o C respectively in an attempt to formulate a root end filling cement. Materials were investigated by X-ray diffraction and Transmission-electron microscope. The formulated cement comprises 60 wt% Tricalcium-silicate, 20 wt% Tetracalcium-phosphate and 20 ...

The application of mineral trioxide aggregates (MTA) cement during the root canal obturation is gaining concern due to its bioactive characteristic to form an apatite in dentinal tubules. In this regard, this study was to assess the biomineralization of dentinal tubules following root canal obturation by using pozzolan-based (Pz-) MTA sealer cement (EndoSeal MTA, Maruchi). Sixty curved roots (m...

This study investigated the solubility of mineral trioxide aggregate (MTA) and Portland cement since its mixture until 672 hours, by means of two complimentary methods. Metal ring molds filled with the cements were covered with distilled water and, at each experimental time (3, 24, 72, 168, 336 and 672 hours), were weighed as soon as the plates in which the samples have been placed. Empty rings...

The present study aimed at evaluating the cytotoxic effects of a novel cement called CER on periodontal fibroblast-like cells of mice (MDPL-20), in comparison with different formulations of Mineral Trioxide Aggregate (MTA), by means of the cell viability test (MTT) and cell morphology analysis. Thirty-two round-shaped samples were fabricated with the following cements: white MTA, white and gray...

introduction : root-end preparation and restoration with an endodontic material are required when nonsurgical endodontic retreatment has failed or is impossible. the present clinical study reports the treatment outcomes of periradicular surgery using calcium-enriched mixture (cem) cement. materials and methods: a prospective outcome study of periradicular surgery using cem was conducted on 14 p...

Objective. The aim of this study was to evaluate the radiopacity of two conventional cements (Zinc Cement and Ketac Cem Easymix), one resin-modified glass ionomer cement (RelyX Luting 2) and six resin cements (Multilink, Bistite II DC, RelyX ARC, Fill Magic Dual Cement, Enforce and Panavia F) by digitization of images. Methods. Five disc-shaped specimens (10 × 1.0 mm) were made for each materia...
