introduction: osteoblasts and periodontal ligament cells are major cells for wound healing after root end resection. the interaction of osteoblasts with filling materials could play a critical role in healing of surgical lesion. adhesion and spreading of cells on material surface are the initial phase for cellular function. the purpose of the present study was the evaluation of morphology and a...

introduction: biocompatibility is a desirable feature for root-end filling materials. in this study we aimed to compare a new material called cold ceramic (cc) with intermediate restorative material (irm) and mineral trioxide aggregate (mta) using methyl-tetrazolium bromide (mtt) assay. materials and methods: the materials were tested in fresh and set states: (n=108). the cytotoxicity was compa...

the aim of this study was to evaluate the marginal adaptation of biodentine in comparison with mineral trioxide aggregate (mta) and intermediate restorative material (irm), as a root end filling material, using scanning electron microscopy (sem).thirty permanent maxillary central incisors were chemo-mechanically prepared and obturated. three millimetres of the root end were resected and 3mm ret...

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...

The purpose of a root-end filling is to establish a seal between the root canal space and the periradicular tissues. As root-end filling materials come into contact with periradicular tissues, knowledge of the tissue response is crucial. Almost every available dental restorative material has been suggested as the root-end material of choice at a certain point in the past. This literature review...

this case report presents conservative management of unset mineral trioxide aggregate (mta) after being placed as a root-end filling material following periapical surgery. periapical surgery was indicated for a maxillary lateral incisor of a 15-year-old male due to persistent exudate and a large periapical lesion. during surgery angelus mta was placed as root-end filling. the next session it wa...

introduction: sealing ability is an important factor for a root-end filling material in endodontic surgeries. this in vitro study aimed to compare the sealing ability of mineral trioxide aggregate (mta) and a new endodontic cement named calcium enriched mixture (cem) cement as root-end filling materials. materials and methods: the experiments were carried out in dry, saliva or blood contaminate...

background and aim: the main goal of endodontic treatments is eliminating the etiologic factors of pulpal and periapical diseases as well as maintaining this condition via providing a hermetic seal between periodontium and root canal system. if these were not possible through orthograde approach, periradicular surgery and root-end filling are indicated. review of literature: different materials...

PURPOSE The aim of this study was to answer the question: For patients requiring apicoectomy (apicectomy/root-end resection) and retrograde (root-end) obturation (filling), which retrograde obturation (root-end filling) material(s) is/are the most effective, as determined by reduction in periapical radiolucency and elimination of signs and symptoms? MATERIALS AND METHODS A MEDLINE and a Cochr...
