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,...

Odontoblasts produce most of the extracellular matrix (ECM) components found in dentin and implicated in dentin mineralization. Major differences in the pulp ECM explain why pulp is normally a non-mineralized tissue. In vitro or in vivo, some dentin ECM molecules act as crystal nucleators and contribute to crystal growth, whereas others are mineralization inhibitors. After treatment of caries l...

( o ( a p bstract his study evaluated the histomorphologic response of uman dental pulps capped with mineral trioxide agregate (MTA) and Ca(OH)2 cement (CH). Pulp expoures were performed on the occlusal floor of 40 human ermanent premolars. After that, the pulp was capped ither with CH or MTA and restored with composite esin. After 30 and 60 days, teeth were extracted and rocessed for histologi...

The literature is almost devoid of scientific studies of diagnosis of pulpal pathology in primary and permanent teeth with open apices. Most reports are empirical or retrospective studies without adequate prior knowledge of preexisting conditions or histologic findings leading to the necessity of pulpal procedures. Appropriate diagnostic tests and their effectiveness are documented for both gro...

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 (n=2...

INTRODUCTION The aim of this trial was to compare clinical and radiographic success rates of direct pulp capping (DPC) using a novel biomaterial called Calcium Enriched Mixture (CEM) cement versus Mineral Trioxide Aggregate (MTA) in primary molar teeth. MATERIALS AND METHODS In this randomized clinical trial 42 deciduous molars in 21 patients who had at least two teeth requiring DPC, were tre...

INTRODUCTION Direct pulp capping (DPC) is coverage of exposed pulp by a biocompatible material after traumatic or carious exposure. The purpose of this procedure is to seal against bacterial leakage, stimulate dentinal barrier formation, and maintain the vitality of pulp. Several factors contribute to the consequence of this treatment such as material and the procedural technique. The aim of th...
