OBJECTIVE The objective of this study is to evaluate the awareness of patients with dental fillings about the toxicity of mercury in dental amalgam. MATERIALS AND METHODS Adult patients having at least one amalgam filling in their mouth were recruited in the Oral Diagnosis Department of OAUTHC, Ile-Ife Dental Hospital. Participants were recruited consecutively as they report in the clinic. Da...

Abstract:In recent years, there have been many attempts to improve the properties of dental amalgam. The aim of the present investigation was fabrication and characterization of dental amalgams containing TiO2 nanoparticles and evaluation of their compressive strength, antibacterial and corrosion behavior. In this experimental research, TiO2 nanoparticles (TiO2 NPs) were added to reference amal...

When I graduated from dental school in 1987, dental amalgam was essentially the only material available for the direct restoration of carious posterior teeth. Dentin bonding was in its first generation of technological development in restorative dentistry, and composite resin restoration of posterior teeth was carried out with caution by some dentists, but avoided by most. Even at that time, th...

objective: the purpose of the present study was to assess the microleakage of composite restorations with and without a cervical amalgam base and to compare the results of dif-ferent composites and bonding agents. materials and methods: one hundred and twenty mesio-occlusal (mo) and disto-occlusal (do) class ii cavities were prepared on sixty extracted permanent premolar teeth. the teeth were r...

Rhodamine B, a fluorescent substance, was used as a tracer to investigate in vitro early microleakage from around amalgam restorations in machinable mica glass-ceramic after thermal stress. Five types of amalgam, i.e., low-copper spherical, low-copper lathe-cut, high-copper admixture, high-copper lathe-cut, and high-copper spherical, were examined in the present study. The results indicated tha...

We completely characterize the boundedness on Wiener amalgam spaces of the short-time Fourier transform (STFT), and on both L and Wiener amalgam spaces of a special class of pseudodifferential operators, called localization operators. Precisely, sufficient conditions for the STFT to be bounded on the Wiener amalgam spaces W (L, L) are given and their sharpness is shown. Localization operators a...

The placement of intermediary cement bases under deep preparations for amalgam restorations is a recommended procedure in restorative dentistry. The base is of low thermal conductivity and thus protects the pulp from thermal shock.1 Bases should also possess sufficient strength to withstand the forces of condensation and mastication transmitted through the amalgam restoration.2'3 The effect of ...
