AIM OF THE WORK Aim of the work was to execute a review of the international literature about the cementation of zirconia restorations, analyzing the properties of the cements most commonly used in clinical activities. MATERIALS AND METHODS It was performed, through PubMed, a bibliographic search on the international literature of the last 10 years using the following limits: studies in Engli...

UNLABELLED The need to develop new dental luting agents in order to improve the success of treatments has greatly motivated research. OBJECTIVE The aim of this study was to evaluate the diametral tensile strength (DTS) and film thickness (FT) of an experimental dental luting agent derived from castor oil (COP) with or without addition of different quantities of filler (calcium carbonate - CaC...

0 NE of the prime considerations in the selection of a temporary filling material is the material’s ability to seal the margins of the cavity within which it is placed. Temporary filling materials are used in many phases of dentistry. During restorative dental procedures, temporary filling materials are used to protect the prepared tooth surface until the final restoration is placed. During end...

The potential mutagenicity of a zinc phosphate (Poscal), a polycarboxylate (Aqualox) and glass ionomer cements with (Argion) and without (Meron) silver reinforcement were characterized by employing the Ames Salmonella/microsome test. The materials were eluted in dimethyl sulphoxide or physiologic saline and the aliquots were used either immediately or after an incubation period of 24h at 37 deg...

The objective of this study was to investigate the effect of various luting cement systems on bond strength of fibre-reinforced posts to root canal dentine. 40 extracted single rooted sound premolar teeth were root filled, decoronated and randomly divided into four groups. Fibre posts, AesthetiPlusTM (Bisco,Inc. Schaumburg, IL, USA) were cemented using four luting cements: Group A (control): El...

Glass-ionomer cements were developed by Wilson and McLean at the Laboratory of the Government Chemist in England in 1965. They were a logical addition to the family of water-based dental cements, comprising silicate cement, zinc phosphate cement and zinc polycarboxylate cement. Since their commercial introduction, they are now available in essentially two types. ‘Conventional’ glass-ionomers co...

Microleakage is related to recurrent decay, inflammation of vital pulps, and reinfection of previously treated root canals. The purpose of this investigation was to compare the abilities of new adhesive cements and conventional nonadhesive controls to prevent microleakage under stainless steel crowns on primary anterior teeth. Standardized preparations were made, and stainless steel crowns were...

The Phenolate Cement Zinc oxide-eugenol cements have always been regarded as the blandest in terms of their effect on the dental pulp. For this reason, these materials were commonly used as the control in biocompatibility pulp research studies on cements and restorative materials. Zinc oxide-eugenol cements have traditionally been used as temporary restoratives because of the sedative effect on...

Calcium phosphate cements (CPCs) are successfully used as bone substitutes in dentistry and orthopaedic applications. This study investigated the physico-chemical-mechanical properties of and in vitro biological properties (cell response) of CPCs prepared with amorphous calcium carbonate phosphate (ACCP) doped with magnesium (ACCP-Mg), zinc (ACCp-Zn) or fluoride (ACCP-F) ions. The experimental ...
