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...

Background The aim of this study was to evaluate the discoloration induced by CEM cement, Portland cement (PC) and MTA mixed with propylene glycol (MTA-PG) in comparison to White MTA. Material and Methods Ninety extracted premolar and canine teeth were resected 2 mm below the CEJ. The coronal part of crown was prepared with peeso reamer and Gates-Glidden drills, and the specimens were randoml...

In modern endodontics, vital pulp therapy (VPT) has been considered an ultra-conservative treatment modality. Based on the level of pulp preservation, VPT includes stepwise excavation, indirect pulp capping (IDPC), direct pulp capping (DPC), miniature pulpotomy (MP), partial/Cvek pulpotomy and coronal/complete pulpotomy (CP). The present article reviews the treatment outcomes of 94 permanent te...

BACKGROUND Providing an apical stop in open apex roots is one of the endodontic challenges. The aim of present study was to compare the surface hardness of both mineral trioxide aggregate (MTA) and calcium-enriched mixture (CEM) cement at different setting situations. MATERIALS AND METHODS A total of 40 freshly extracted human teeth with a single root and normal apex and no obvious caries or ...

AIM The aim of this study was to compare the bacterial leakage of mineral trioxide aggregate (MTA), calciem enriched cement (CEM), and bone cement (BC) as repair materials in furcal perforations. METHODS The pulp chambers of 57 human mandibular molar teeth were accessed and the root canal orifices were located. The roots were horizontally sectioned in the middle third. Composite resin was use...

introduction: this in vitro study compared the cytotoxic effects of three commercially available mta formulations naming proroot mta (pmta), angelus mta (amta), and root mta (rmta), with calcium-enriched mixture (cem) cement and a new nanohybrid mta (nmta) on human dental pulp stem cells (dpsc). methods and materials: four disc-shaped specimens of each material were prepared. after completion o...

INTRODUCTION The aim of this study was to compare the discoloration potential of calcium-enriched mixture (CEM) cement, white mineral trioxide aggregate (WMTA) and calcium hydroxide (CH), after placement in pulp chamber. METHODS AND MATERIALS Access cavities were prepared in 40 intact maxillary central incisors. Then, a 2×2 mm box was prepared on the middle third of the inner surface on the b...

OBJECTIVE Immediate restoration after vital pulp therapy is essential in order to create and maintain effective coronal seal. PURPOSE OF STUDY The aim of this study was to evaluate the shear bond strength of recently used pulp capping materials: white mineral trioxide aggregate (MTA), and calcium enriched mixture cement (CEM) to composite resin with the use of etch-and-rinse and self-etch adh...

Introduction: The aim of this study was to assess the fracture strength of immature single-rooted teeth restored with fiber post and apical plug. Materials &Methods: In this experimental study, fifty mandibular premolars were divided into five groups. The coronal and apical portions were cut to obtain15±1 mm root lengths and cleaning &shaping were performed. Peeso reamer #4 was passed t...

INTRODUCTION Nano-hydroxyapatite (NHA) has been used for regeneration of osseous defects. Calcium-enriched mixture (CEM) cement is also used for various dental treatments. This trial compared the efficacy of NHA and CEM cement for direct pulp capping (DPC) of sound primary teeth. METHODS AND MATERIALS In this randomized clinical trial with split-mouth design, after attaining informed consent,...
