PURPOSE To assess periradicular lesions clinically and by computed tomography (CT) after endodontic surgery using either Portland cement or mineral trioxide aggregate (MTA) as a root-end filling material. METHODS Three patients diagnosed with periradicular lesions by cone-beam CT underwent endodontic surgery with root-end filling. Patient A was treated with MTA as the root-end filling materia...

AIM This was to carry out a review of the literature concerning mineral trioxide aggregate (MTA) and Portland cement with regards to clinical, biological and mechanical findings and a possible substitution of MTA through Portland cement for endodontic use. STUDY DESIGN Electronic literature search of scientific papers from January 1993 to January 2009 was carried out on the MEDLINE and Scopus...

This study aimed to assess the influence of the type of endodontic sealer (salicylate resin-based sealer vs. two endodontic sealers) and the time of fiber post cementation after root filling on the post adhesion to bovine root dentin. Sixty bovine roots were assigned to six groups (n=10), considering an experimental design with two factors (factorial 3x2): endodontic sealer factor in three leve...

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 pe...

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 aim of this study was to evaluate the influence of eugenol-containing endodontic sealers and luting strategy on the pull-out bond strength of glass fiber posts to dentin. Sixty-four bovine incisors were randomly assigned into two groups of 32 specimens each for obturation procedure with gutta-percha only, or with Pulp Canal Sealer EWT Subsequently, the roots were prepared for the fiber post...

background and aims. biocompatibility of root-end filling materials is a matter of debate. the aim of this study was to compare the biocompatibility of a variety of commercial proroot wmta cements and a resin-based cement (geristore®) with different ph values of setting reaction and different aluminum contents, implanted into the subcutaneous connective tissue of rats at various time intervals....

INTRODUCTION This in vitro study measured and compared pH and phosphate and calcium ions release of a new endodontic material (CEM cement), mineral trioxide aggregate (MTA), and Portland cement (PC) using UV-visible technique, atomic absorption spectrophotometry methods, and pH meter, respectively. MATERIALS AND METHODS Each material was placed in a plastic tube (n=10) and immersed in a glass...

background: introducing new endodontic cements should await comprehensive investigations and new formulations have to be tested in vivo before applying in human beings. so, the purpose of this study was to compare the biocompatibility of new endodontic cements, calcium aluminate α-aluminate cement (caac), calcium aluminate α-aluminate plus cement (caac plus), and a mixture of wollastonite and c...

statement of the problem: endodontic surgery if required is considered as an additive therapy after classic endodontic treatments. the most prevalent type of endodontic surgeries are apicoectomy and corrective surgeries. type of material applied in apicoectomies is of high importance. root end filling material should not only be biocompatible but also provide appropriate seal. considering these...
