Pulpal response of four calcium hydroxide liners, MPC 10, MPC 12, Dycal and Pulpdent were tested on primary and permanent teeth with zinc oxide and eugenol (ZOE) and silicate as controls. Responses of the pulps were evaluatedi in Rhesus monkeys, utilizing Class V cavity preparations at 3 days, 5 and 8 weeks. An equivalent number of anterior and posterior teeth were studied for all compounds. Th...

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 Computed tomography (CT) and cone-beam CT (CBCT) are valuable diagnostic aids for many clinical applications. This study was designed to compare the gray scale value (GSV) and Hounsfield unit (HU) of selected dental materials and various hard tissues using CT or CBCT. METHODS AND MATERIALS Three samples of all test materials including amalgam (AM), composite resin (CR), glass ion...

Statement of Problem: Despite the wide range of new dental materials, there is still a need for biomaterials demonstrating high biocompatibility, antimicrobial effects and ideal mechanical properties. Purpose: The aim of this study was to histologically evaluate the pulpal response to a conventional glass ionomer, a resin modified glass ionomer and a calcium hydroxide in human teeth. Materials ...

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...

STATEMENT OF PROBLEM Cementation of implant prostheses is a common practice. Excess cement in the gingival sulcus may harm the periodontal tissues. Identification of the excess cement may be possible with the use of radiographs if the cement has sufficient radiopacity. PURPOSE The purpose of this study was to compare the radiographic density of different cements used for implant prostheses. ...

Twenty-six patients, 5-13 years of age, demonstrated 67 pairs of contralateral occlusal fissure and buccal, or lingual pit carious lesions which were restored with a spherical high-copper amalgam. One restoration of each pah" was allowed to remain as carved, while the other was finished and polished 24 hours after insertion. Each restoration was evaluated clinically by three independent examine...

Neurocutaneous syndrome (NCS), a newly discovered toxicity disorder, is described in light of our new understanding of its relationships with the causative agents included in the dental liners used in afflicted patients. NCS is characterized by neurological sensations, pain, depleted energy and memory loss as well as itchy cutaneous lesions that may invite various opportunistic infections. Comp...
