Introduction: Glass ionomer and polycarboxylate cement have different effects on the marginal seal, microleakage, pulp tissue stimulation, and gingival health. The purpose of this study was to assess the effect of these cement on the gingival health of primary molars restored with stainless steel crowns (SSC). Methods: A total number of 34 children were selecte...

1. The following dental cements are listed in order of decreasing mean bonding strenghts on varnish-free dentin: polycarboxylate, zinc phosphate, EBA, Fynal, and CBA. 2. The application of either Copalite or Varnal decreased the dentinal bonding strength of polycarboxylate and zinc phosphate cements. There was no change for CBA cement. 3. The application of Copalite and Varnal increased the den...

BACKGROUND AND AIMS This in vitro study was designed to compare enamel demineralization depths adjacent to bands cemented with zinc polycarboxylate, glass ionomer (GI) and resin-modified glass ionomer (RMGI), in order to achieve minimal enamel demineralization during orthodontic treatment. MATERIALS AND METHODS Sixty fully developed extracted third molars were randomly divided into three test...

Incorporating Graphene Oxide (GO) in concrete composite has been a good alternative to Pristine due its hydrophilic nature and ability readily disperse water the consequent cementitious mix. The addition of GO mix found enhance mechanical properties. This paper aims assess abrasion resistance incorporated for application road pavement design. Experiments strength terms compression, workability ...

Due to their remarkable mechanical properties, multiwall carbon nanotubes (MWCNTs) are considered by many researchers to be a highly promising filler and reinforcement agent for enhanced performance cementitious materials. Currently, however, achieving an effective dispersion of MWCNTs remains a major challenge in developing high performance nano-cementitious composites, since carbon nanotubes ...

OBJECTIVE To evaluate the clinical efficacy of polycarboxylate cement as retrograde filling material. DESIGN A prospective clinical study was made of 25 patients subjected to periapical surgery with ultrasound and magnifying loupes, in which polycarboxylate cement was used as retrograde filling material. Measurements were made of the area and diameter of the lesions pre- and postoperatively, ...

Synopsis: In terms of workability of cement based materials, ettringite formation is of major importance. Thus, the interaction between polycarboxylate-ether based superplasticizers (PCE) and various pure cement clinker and hydrate phases is investigated by means of rheological, adsorption and zeta potential measurements. Microstructural analysis of fresh pastes is carried out using cryo-micros...
