introduction: the aim of this randomized clinical trial was to compare the histologic pulp tissue response to one-step direct pulp capping (dpc) and miniature pulpotomy (mp) with mineral trioxide aggregate (mta) after application of dexamethasone in healthy human premolars. methods and materials: forty intact premolars from 10 orthodontic patients, were randomly chosen for dpc ( n =20) or mp ( ...

i ntroduction: the aim of this study was to evaluate the clinical and histological status of the pulp in sound human premolars after direct pulp capping (dpc) with four different dpc methods/materials. methods and materials: this study was conducted on eight volunteers who had to extract four first premolars due to orthodontic treatment. subsequent to tooth isolation, standardized class i occlu...

introduction: flow rate (fr) and compressive strength (cs) are important properties of endodontic biomaterials that may be affected by various mixing methods. the aim of this experimental study was to evaluate the effect of different mixing methods on these properties of mineral trioxide aggregate (mta) and calcium-enriched mixture (cem) cement. materials and methods: hand, amalgamator and ultr...

Mineral trioxide aggregate is the mainstay of treatment of large internal resorption defects. But its cost may be a deterrent to its use in some patients. The present case report describes the successful endodontic management of an extensive internal resorptive lesion in a mandibular molar with metal reinforced glass ionomer cement.

Apexification is a widely used technique to manage immature permanent teeth and can be performed either using calcium hydroxide (Ca(OH)2) or mineral trioxide aggregate (MTA). This paper illustrates a case report of a unsuccessful apexification with Ca (OH)2 of amaxillary incisor that was then treated by an apical barrier made of MTA.

We described a combined periodontal-endodontic lesion, which was caused by a palatogingival groove and an additional root. An interdisciplinary approach involving endodontic therapy, mineral trioxide aggregate (MTA) filling, root resection, guided tissue regeneration, and papillary reconstruction was used for the case. The tooth presents morphologically and functionally normal except tooth disc...

OBJECTIVES The purpose of this study was to evaluate the in vitro sealing ability of three repair materials. Mineral trioxide aggregate (MTA; Group A), calcium phosphate cement (CPC; Group B), and light cured glass ionomer cement (GIC; Group C) when used to repair the perforation created in the pulpal floor of fifty extracted human permanent molars. MATERIALS AND METHODS Preparation of access...
