OBJECTIVE To compare the retention and the caries preventive effect of a glass-ionomer developed for fissure sealing (Fuji III) and a chemically polymerized resin-based fissure sealant (Delton). DESIGN A split mouth randomized design using contralateral teeth. SETTING WHO Regional Demonstration, Training and Research Center for Oral Health, Damascus, Syrian Arab Republic. SAMPLE AND METHO...

Restoration of primary teeth continues to be an important facet of restorative dentistry. In comparison to restorations in permanent dentition, the longevity of those in primary teeth is significantly different for all materials. This makes the assessment of these fillings as a separate group meaningful. As there is lack of supporting clinical data with regard to the restoration of primary inci...

The aim of this work was to characterize the initial wear kinetics of two different types of glass ionomer cement used in dentistry (the conventional glass ionomer cement and the resin-modified glass ionomer cement) under sliding friction after 28-day storing in distilled water or Ringer's solution. Sliding friction was applied through a pin-on-disk tribometer, in sphere-on-plane contact condit...

Aim: The aim of the study was to evaluate the surface conditioned dentin and its effect on microleakage of metal copings luted with glass-ionomer cement. Objectives: (1) To evaluate the morphology of unconditioned and conditioned dentin, (2) to evaluate the elemental composition of unconditioned and conditioned dentin, (3) to evaluate and compare the microleakage of metal copings luted with gla...

PURPOSE The purpose of this study was to compare the dislodgement strengths and fracture types for reattached tooth fragments using a light-cured composite resin material, a hybrid light-cured glass ionomer base, and a hybrid light-cured glass ionomer liner. METHODS Seventy-five bovine incisor teeth were fractured, randomly divided into three groups of equal number, and then luted back togeth...

PURPOSE This study compared the influence of two luting cements on the clinical performance of single crowns. MATERIALS AND METHODS Twenty patients received 39 pairs of metal-ceramic and Procera crowns cemented with zinc phosphate and resin-modified glass-ionomer luting cement (Vitremer) in a split-mouth randomized pattern blinded to the recipient. The crowns were examined immediately after c...

Glass ionomer (GI) sealants can be utilised when a resin-based sealant is indicated but cannot placed due to poor moisture control, resulting from either inadequate tooth eruption or patient co-operation. GI hydrophilic, making it more compatible with the oral environment. Another significant advantage of their action as fluoride reservoir, aiding in remineralisation enamel.

AIMS The aim was to evaluate the incidence of root fracture of endodontically treated teeth reinforced with glass-fiber posts and metal posts luted with different luting cements. MATERIALS AND METHODS Forty maxillary central incisors were sectioned at 1 mm of the cementoenamel junction and endodontically treated. The teeth were divided into four groups (n = 10) and restored with prefabricated...
