93 Abstract The findings presented here suggest that mercury poisoning from dental amalgams may play a role in the etiology of oral health disorders in multiple sclerosis (MS) patients. Comparisons between MS subjects with dental amalgams and a control group of MS subjects without amalgams found significantly fewer oral cavity symptoms per subject in the amalgam-removal group during twelve mont...

This in vitro study aimed to investigate the effects of glass-ionomer and flowable composite liners on the fracture resistance of Class II amalgam and composite restorations. Group 1 cavities were restored with amalgam and Group 4 cavities with nanofill composite after the application of a dentin-bonding agent. For the remaining groups, light-cured-glass-ionomer liner was used in a gingival flo...

CONTEXT No randomized trials have been published that address the concern that inhalation of mercury vapor released by amalgam dental restorations causes adverse health effects. OBJECTIVE To compare the neuropsychological and renal function of children whose dental caries were restored using amalgam or mercury-free materials. DESIGN AND SETTING The New England Children's Amalgam Trial was a...

Amalgam has been used in the restoration of structurally compromised posterior teeth for many years. When placing large amalgam restorations, replacement of weak cusps with restorative material is recommended to prevent tooth fracture. This recommendation can be modified with new guidelines using modern adhesive techniques. Semidirect and indirect inlay/onlay composite restorations have progres...

The restoration of broken down puIpless molar teeth generally implies the provision of a cast post and core with a crown. In this research the failure resistance of some restoration methods utilizing amalgam was investigated under an oblique load. The results suggest that intracoronal reinforcement with a prefabricated dowel did not significantly increase the in vitro resistance. It is expected...
