Introduction: Amalgam, which can be applied with or without dowel, is one of the commonly used restorative materials for core restoration in pulpless teeth. The current study aimed to compare the shear strength of amalgam cores with and without dowel. Methods: A total number of 20 recently extracted mandibular premolars were assigned to two groups of 10 equal s...

BACKGROUND Many patients have complex health complaints they attribute to dental amalgam. There is some evidence of symptom relief after removal of amalgam. OBJECTIVE The aims of this study were to assess the total symptom load in patients with all their amalgam fillings removed, and to investigate the self-reported improvement of health with regard to precautions taken under amalgam removal ...

The wear of cental amalgam was studied by single- and double-pass sliding and by a silicon carbide abrasion test. A dispersed amalgam showed significantly better resistance to two-body abrasion than the spherical amalgams tested. The wear amalgam was determined by resistance to penetration and by a ductile mode of surface failure over the load range studied. Differences in the wear of amalgam a...

This is a rare case of amalgam allocation in an alveolar wound of an extracted third molar. During the extraction of a mandibular third molar to a 36-year-old woman, the adjacent mandibular second molar was broken. The dentist decided to put an amalgam filling to the mandibular second molar directly after the extraction and during the same appointment. The patient soon experienced an acute cont...

Dental composites have almost entirely replaced amalgam restorations in the recent times. Amalgam were highly un-aesthetic and toxic to human body. prove be an aesthetic biocompatible alternative dental amalgam. But however, composite resins present with certain limitations such as inadequate mechanical properties wear resistance contact areas, primarily posterior teeth, contrast Therefore, not...

Aim: To compare marginal seal at tooth-material and material-material interfaces in the proximal box in combined amalgam/composite resin restorations. Methods: Mesio-occlusal-distal (MOD) cavities were prepared in 35 premolars and permanent molars with carbide bur. The distal proximal box was restored with amalgam (Permite, SDI) until reaching the height of pulpal floor. Dental tissues were etc...

OBJECTIVE To determine the amount of amalgam entering the waste stream during removal of dental amalgam restorations. METHODS Dental amalgam restorations were removed from anatomic replica teeth and natural teeth by means of a tungsten carbide bur, a high-speed handpiece and a conventional suction system. The weight of amalgam particles trapped in the primary and secondary solids separators w...

BACKGROUND Mercury vapor poses a known health risk with no clearly established safe level of exposure. Consequently there is debate over whether the level of prolonged exposure to mercury vapor from dental amalgam fillings, combining approximately 50% mercury with other metals, is sufficiently high to represent a risk to health. The objective of our study is to determine if mercury exposure fro...
