An important requirement for dental materials placed in direct contact with living tissues is biocompatibility. The purpose of this study was to evaluate the antiproliferative activity of three dental materials (mineral trioxide aggregate, zinc oxide-eugenol cement, and glass-ionomer cement) against a panel of established fibroblastic cell lines (L929, BHK21/C13, and RPC-C2A). The materials wer...

The purpose of this report was to present the case of a patient wherein revascularization of the necrotic infected pulp space of an immature permanent maxillary central incisor tooth was induced in vivo by stimulation of a blood clot from the periapical tissues into the canal space. This was achieved after disinfection of the canal space with a topical antibiotic paste followed by a blood clot ...

introduction: some studies in dental literature have proposed that short term and long term exposure of root dentin to calcium hydroxide predisposes it to fracture. mineral trioxide aggregate (mta) and a recently introduced endodontic material, calcium-enriched mixture (cem) cement may be used instead of calcium hydroxide and might have an effect on the strength of root dentin. therefore, the a...

background and aims: we aimed to assess the bond strength of composite resin to three pulp capping biomaterials; proroot mineral trioxide aggregate (pmta), root mta (rmta) and calcium enriched mixture (cem), using three bonding systems [a total etch (single bond) and two self-etch systems (protect bond and se bond)]. materials and methods: ninety acrylic moulds containing a 6×2 mm hole were div...

introduction: the aim of this randomized clinical trial split-mouth study was to compare the postoperative pain following use of mineral trioxide aggregate (mta) and calcium-enriched mixture (cem) cement as pulpotomy agents in carious primary molars. methods and materials: forty-seven children aged between 6-10 years old were enrolled in this study. each child had two cariously involved primary...

objective: furcal perforation is an undesirable complication that may occur during root canal therapy and seriously compromises the prognosis of endodontic treatment. the prognosis of furcal perforation repair depends on the prevention of bacterial infection of the perforation site. thus, use of a biocompatible material for complete sealing of the perforation site is critically important. this ...

Endodontic treatment options for immature, nonvital teeth conventionally include surgical endodontics, apexification with calcium hydroxide, or single visit mineral trioxide aggregate plug. A new treatment option of revascularization has recently been introduced. It involves disinfecting the root canal system, providing a matrix of blood clot into which cells could grow, and sealing of the coro...

AIM The study was undertaken to evaluate mineral trioxide aggregate (MTA) clinically and radiographically as a pulpotomy agent in immature permanent teeth whose pulps were exposed by a complicated crown fracture. MATERIALS AND METHODS Thirty incisors with exposed pulps in twenty-nine patients were examined for this retrospective study. According to exclusion criteria, only twenty-seven teeth ...

INTRODUCTION A radicular perforation caused by an inflammatory internal root resorption was present in a maxillary lateral incisor. METHODS The root canal preparation was completed with hand files and thorough irrigation. Calcium hydroxide was placed as a temporary dressing for 10 days. At the second visit, the root canal with resorption lacuna was filled with warm vertical compaction of gutt...
