Years ago, the restorative material options for the dental practitioner were limited. Direct placement materials available were either amalgam or silicate. Amalgam has long been recognized as a forgiving restorative material that works well in a variety of circumstances. Advantages of amalgam include cariostatic properties, the ability to work in varied moisture conditions, and quick bulk place...

Objective. This in vitro study uses measurements of fracture resistance to compare maxillary premolars restored with the bonded amalgam technique using a new resin luting cement, glass ionomer, and resin-modified glass ionomer as the bonding agents. Materials. Eighty-five sound maxillary premolars were selected and randomly assigned to one of five test groups of 17 teeth each. One group of inta...

Periodontal structures are vital tissues that could be affected by the surrounding environment. Dental materials and/or restorations may trigger negative response such as gingival inflammation and bone loss from periodontal tissues. The objective of this study was to report the prevalence of overhang interproximal amalgam restorations by undergraduate students at College of Dentistry, King Saud...

Background and aims. The majority of failures in Class II amalgam restorations occur in the first primary molar teeth; in addition, use of compomer instead of amalgam for primary molar teeth restorations is a matter of concern. The aim ofthe present study was to compare the success rate of Class II compomer and amalgam restorations in the first primary molars. Materials and methods. A total of ...

INTRODUCTION One of the biggest disadvantages of dental amalgam is that gaining its ultimate strength is a slow process. The use of a rapid-setting amalgam with high early compressive strength could be a better option in preventing early fractures in pediatric dentistry. The aim of this study was to determine the effect of diode laser irradiation on compressive strength of dental amalgam. MET...

There is widespread concern regarding the safety of silver-mercury amalgam dental restorations, yet little evidence to support their harm or safety. We examined whether mercury dental amalgams are adversely associated with cognitive functioning in a cross-sectional sample of healthy working adults. We studied 550 adults, 30-49 years of age, who were not occupationally exposed to mercury. Partic...

BACKGROUND Whether dental amalgam fillings (containing mercury) are hazardous is a long-standing issue, with few epidemiological investigations. Allegations have particularly involved nervous system disorders, such as multiple sclerosis, Alzheimer's disease, and chronic fatigue syndrome. This retrospective cohort study, the largest of its kind, contained people in the New Zealand Defence Force ...
