OBJECTIVE To investigate and compare the amount of fluoride release of conventional, resin modified and nanofilled resin modified glass ionomer cements. MATERIALS AND METHODS Tablets of glass-ionomer cements were immersed in deionized water and incubated at 37°C. After 1, 2, 7, 15 and 30 days, fluoride ion was measured under normal atmospheric conditions by fluoride ion selective electrode. B...

AIM To test the null hypothesis that there are no significant differences in the reusability of debonded brackets with regard to debonding technique and adhesive used. METHOD Ninety-six osteotomed third molars were randomly assigned to two study groups (n = 48) for bonding of a 0.018-inch bracket (Ormesh, Ormco) with either a composite adhesive (Mono-Lok2; RMO) or a glass ionomer cement (GIC;...

OBJECTIVE Immediate restoration after vital pulp therapy is essential in order to create and maintain effective coronal seal. PURPOSE OF STUDY The aim of this study was to evaluate the shear bond strength of recently used pulp capping materials: white mineral trioxide aggregate (MTA), and calcium enriched mixture cement (CEM) to composite resin with the use of etch-and-rinse and self-etch adh...

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...

Complete debridement, thorough disinfection and optimal sealing of the root canal system are the major challenges associated with endodontic treatment of teeth with open apices. In such teeth, thin radicular dentinal walls are susceptible to fracture. To ensure a better prognosis in such fractured prone thin dentinal walls, internal radicular reinforcement with various adhesive materials like g...

Light cured glass ionomer cements offer improved handling characteristics. Photocuring within the cavity preparation may assist in decreasing the moisture contamination and dehydration difficulties associated with the early stage of setting reaction. The success of restoration depends on good adhesion between glass ionomer cement and the tooth structure. Various dentin conditioners have been ad...

Tooth coloured adhesive restorative materials are widely accepted and used for the restoration of carious and non-carious cervical lesions. The aim of this study was to evaluate and compare the solubility and sorption values of compomer (Dyract ®), conventional glass-ionomer(Fuji II ) and resin modified glassionomer (Fuji II LC improved) cements in various beverages such as tea, coffee, coca-co...

The number of publications reporting on the survival of ART sealants and ART restorations has increased considerably in recent years. A systematic investigation of their longevity is therefore warranted. Based on three exclusion criteria, a literature search in the electronic libraries Pubmed and Medline revealed 28 eligible publications for inclusion in a meta-analysis. High mean survival rate...

OBJECTIVE To determine the fracture resistance of endodontically treated anterior teeth restored with a novel nonmetallic post in combination with self-etching adhesives. MATERIALS AND METHODS Extracted maxillary anterior teeth were sterilized with gamma irradiation, and each crown was severed 2 mm above the cementoenamel junction. Endodontic treatment was performed, and the teeth were divide...

The aim of this study was to assess the influence of etching and light-curing time on the shear bond strength (SBS) and adhesive remnant index (ARI) of a resin-modified glass ionomer cement (RMGIC) upon debonding of orthodontic brackets. Sixty-eight bovine permanent incisors were obtained and embedded in acrylic resin. Edgewise metallic brackets were bonded to the teeth with Fuji Ortho LC RMGIC...
