This in vitro study evaluated the presence of voids in powder-liquid and capsulated glass ionomer cement. 40 cavities were prepared on root surfaces of maxillary incisors and divided into four groups. Cavities were conditioned with glass ionomer cement liquid (GC Corporation, Tokyo, Japan) in Groups 1 and 3 and with dentin conditioner (GC Corporation, Tokyo, Japan) in Groups 2 and 4. Convention...

Background and Aim: To investigate the radiopacity of different luting, lining and filling dental cements used in prosthetic dentistry in comparison with human and bovine dental hard tissues. Material and methods: Eight cylindrical samples of each material (6 x 1 mm) were prepared from Aqualox (APC), Durelon (DE) and Adhesor Carbofine (ACF) zinc polycarboxylate cements, Cavex zinc oxide eugenol...

OBJECTIVES/HYPOTHESIS From an acoustic aspect, fixation of the medial end of an ossicular replacement prosthesis to the stapedial footplate would be desirable. Technically, ionomer cement seems an ideal material for this purpose. The objective was to determine the aluminum level of the perilymph after the application of ionomer cement on the stapedial footplate. STUDY DESIGN An experimental s...

PURPOSE The aim of this study was to compare the bonding strength, flexural strength, elastic modulus, water absorption and the expansion after water storage of new self-adhesive resin cements to commercially available dental cements. METHODS Two types (hand-mix and auto-mix) of new self-adhesive resin cements (SAC-H and SAC-A, Kuraray Medical), one conventional resin cement (Panavia F2.0), t...

Secondary caries are a worldwide public and socioeconomic problem. The placement of restorations can lead to the development of environmental conditions favorable to microbial colonization, especially on the tooth/restoration interface, which is a predisposing factor for secondary caries. The aim of this study was to evaluate microbial retention on conventional (Chelon-Fil and Vidrion R) and re...

Fluoride release into deionized water from two glass-ionomer cements (Aqua Ionofil and Ceramfil β) and two polyacid-modified composite resins or compomers (Hytac and Dyract AP) was examined over different time periods. Nine cylindrical specimens (2.5 x 8.5 mm) of each material were prepared and allowed to stand in deionized water. The resulting solutions were analyzed for fluoride by the Alizar...

This randomized clinical trial was carried out to compare post cementation sensitivity in vital abutments of metal-ceramic fixed partial dentures using glass ionomer luting cement and resin based luting cement. It analyzed the results of 182 patients whose records were completed during study duration of 09 months at Department of Prosthodontics, AFID, Rawalpindi. Cold sensitivity tests were use...

The retention of zirconia-based ceramic posts (CosmoPost system) luted with glass ionomer and resin cements was evaluated. Thirty-two extracted, caries-free, unrestored teeth were selected and stored in chlorhexidine and water solution. The teeth were endodontically treated and randomly assigned to two groups (n=16). Each tooth was decoronated and prepared to a depth of 10.0 mm from root surfac...

The aim of this study was to test the hypothesis that there is no difference in the fluoride release behavior of resin-reinforced glass ionomer cements before or after fluoride recharge. The materials were divided into 5 groups: 2 resin-reinforced glass ionomer cements used for attaching orthodontic bands, that is, group FOB (Fuji Ortho Band) and group MCB (Multi-Cure Glass Ionomer Orthodontic ...
