The development of biomaterials capable of driving dental pulp stem cell differentiation into odontoblast-like cells able to secrete reparative dentin is the goal of current conservative dentistry. In the present investigation, a biomembrane (BM) composed of a chitosan/collagen matrix embedded with calcium-aluminate microparticles was tested. The BM was produced by mixing collagen gel with a ch...

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,...

Direct pulp capping is the most conservative restorative procedure for protecting the pulp from further insult, permitting healing and repair. Calcium hydroxide Ca(OH) 2 is the most commonly used materials for direct pulp capping . The aim of this study was to compare clinically and radio graphically Ca(OH) 2 with Resin modified glass ionomer (RM-GIC) as a direct pulp capping material. Forty si...

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...

AIM To compare mineral trioxide aggregate (MTA) with calcium hydroxide when used as pulp-capping materials in human teeth. METHODOLOGY Eleven pairs of maxillary third molars in subjects between 20 and 25 years of age were subjected to mechanical pulp exposure. The exposed pulps were capped with MTA or calcium hydroxide, covered with ZOE and restored with amalgam. A total of 14 teeth were extr...

Two hundred direct pulp capping procedures were conducted in the present study. One hundred of them were performed with the CO2 laser, and 100 were conducted conventionally as a control by using a calcium hydroxide preparation. Follow-up examinations were performed after 1 wk and monthly for 12 months after treatment. Thermal tests were used for vitality assessments and laser Doppler flowmetry ...

Coronal fractures of the anterior teeth are a common form of dental trauma that mainly affects children and adolescents. One of the options for managing coronal tooth fractures when the tooth fragment is available and there is no or minimal violation of the biological width is the reattachment of the fragment. This article presents a novel technique for reattachment of obliquely fractured fragm...

The objective of the present study was to determine the frequency of class II type carious lesions in first permanent molars and its possible association with the pulp when examined clinically and radiographically. Two hundred and forty two subjects were examined in the Dept. of Operative Dentistry, Khyber College of Dentistry, Peshawar for the presence of Class II type carious lesions in the p...

1. Adopt the lowest exposure level recommended by the independent NC Science Advisory Board, Option 1 under 2D .1104, which is 33 micrograms per cubic meter (g/m3) for the 24-hour acceptable ambient level, or AAL; 2. Reject the less stringent AALs proposed under Options 2, 3, 4, and 5 for 2D .1104; 3. Reject the exemptions for wastewater treatment systems at pulp and paper mills proposed under ...
