PURPOSE Manufacturers commonly provide information on the physical properties of dental materials, but information on their antibacterial properties is often missing. This study determined the antibacterial properties of four currently used orthodontic band cements against three different strains of Streptococcus mutans. METHODS The cements utilized were Durelon, Ketac, Mizzy Zinc Phosphate, ...

objective: the purpose of this study was to evaluate the solubility of three luting cements in artificial saliva. materials and methods: twenty disks (10×4 mm) of polycarboxylate, zinc phosphate and glass ionomer cements were prepared according to manufactures’ instructions. after setting, they were desiccated and each ten specimens were immersed in artificial saliva with special ph (3 or 5), c...

BACKGROUND Studies have been carried out on endodontically treated teeth restored with and without ferrule, and influence of the cementing medium, to evaluate their effect on fracture resistance. This study was conducted on 28 freshly extracted maxillary central incisors. Specimens were restored with two types of post designs, and cemented with two different luting agents, and tested for fractu...

Yttria partially stabilized zirconia (YPSZ) ceramics are suitable for dental and medical use because of their high fracture toughness and chemical durability. The purpose of this study was to examine the bonding behavior of a dental YPSZ ceramic, Denzir. After being subjected to various surface treatments, Denzir specimens were bonded to each other using an adhesive resin composite, glass ionom...

OBJECTIVE The aim of the present clinical longitudinal study was to observe, over 10 years, the prognosis of abutment teeth restored with fixed prostheses retained by glass ionomer luting cements and one conventional zinc phosphate cement. METHODS Three dentists prepared 135 abutment teeth in 61 patients to retain 81 fixed prostheses. The prostheses were retained by two glass ionomer luting c...

BACKGROUND This study was designed to evaluate the retentive strength of 7 different luting agents on cement-retained implant abutment/analog assemblies. METHODS Fifty-six Steri-Oss implant abutment/analog assemblies and cast superstructures were randomly divided into 7 groups: definitive cements included zinc phosphate cement, Advance, All-Bond 2, Panavia F, and Durelon, while provisional ce...

BACKGROUND: The clinical success rate with zinc phosphate cemented Procera crowns is high. The objective with this study was to determine whether CADCAM processed and zinc phosphate cemented Denzir copings would perform as well as zinc phosphate cemented Procera copings when tested in vitro in tension. METHODS: Twelve Procera copings and twenty-four Denzir copings were made. After the copings h...

The choice of luting agents contributes a significant role in retention of cement retained implant restorations and their precise tensile behaviour needs to be investigated further. The aim of present study is to estimate and compare the difference in tensile bond strength between implant abutments and all ceramic restorations luted with four luting agents. An experimental, single blinded, in-v...
