OBJECTIVE This article estimates the financial impact of a ban on amalgam restorations for selected population groups: the entire population, children, and children and women of childbearing age. METHODS Using claim and enrollment data from Delta Dental of Michigan, Ohio, and Indiana and the American Dental Association Survey of Dental Services Rendered, we estimated the per capita use and an...

Endodontic procedure helps in preservation of a pulpally involved primary tooth by eliminating bacteria and their products and ensures hermetic seal of the root canals with different root canal filling materials so that the primary tooth can complete its function until normal exfoliation can occur without harming the successor or affecting the health of the patient.1 An ideal root canal filling...

Zinc oxide-eugenol (ZOE) is usually applied clinically as dental filling material for thermal insulation and temporary restoration. The objective of this study was to use ZOE as a composite matrix and low melting-point polyester fibers or fabrics as reinforcement. The added fibers or fabrics increased the composite materials’ compressive load by 250 N and 290 N, respectively. Fiber length and t...

context this study aimed to provide an overview of the literature on the radiopacity of dental materials in order to emphasize its importance. evidence acquisition english-language literature was investigated using manual and electronic searches for the terms “radiopacity,” “dental material,” “cement,” “composite,” “ceramic,” “endodontic root canal sealer,” “bone graft,” and “acrylic resin” in ...

The histologic response to intentional perforation in the furcations of 28 mandibular premolars in seven dogs was investigated. In half the teeth, the perforations were repaired immediately with either amalgam or mineral trioxide aggregate; in the rest the perforations were left open to salivary contamination before repair. All repaired perforations were left for 4 months before histologic exam...

Although the corrosion characteristics of dental amalgam have been of considerable interest to dental researchers, it has been difficult to identify the products which form in vivo. This report demonstrates that Sn4(OH)6Cl2 and SnO are formed in vivo and in vitro. The Sn-Cl product is the predominant phase formed by corrosion-induced changes of the Sn8Hg phase of amalgam. It is present in conve...

The purposes of this in vivo study were to determine if placing a sealant over a glass ionomer restoration modifies its fluoride release, and to examine the effect on glass ionomer of a 4-min application of topical fluoride. Fluoride release from glass ionomer preventive resin restorations placed in 21 bovine teeth was measured before and after removing their sealants. Fuji II, Ketac Silver, an...

Background and Aim: To investigate the radiopacity of different luting, lining and filling dental cements used in prosthetic dentistry in comparison with human and bovine dental hard tissues. Material and methods: Eight cylindrical samples of each material (6 x 1 mm) were prepared from Aqualox (APC), Durelon (DE) and Adhesor Carbofine (ACF) zinc polycarboxylate cements, Cavex zinc oxide eugenol...

Dental diseases are among the most common ailments, and dentists in the United States spend over 50% of their time in dental practice rebuilding carious, malformed, and traumatically injured teeth. It is logical, therefore, that the majority of the dental school curriculum is devoted to the diagnosis, prevention, and treatment of teeth with anomalies. Dentists have several choices of materials ...

BACKGROUND Contrary to the situation for amalgam restorations, obtaining acceptable proximal contacts with posterior composite restorations can be difficult. Proximal contacts that are less than ideal may permit food impaction and subsequent caries formation and periodontal problems. PURPOSE The aim of this study was to assess the quality of proximal contacts of posterior composite restoratio...
