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 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...

The purpose of this study was to evaluate the disintegration of luting agents. An intraoral sample holder was made having four holes of 1.4 mm diameter and 2 mm depth. The holder was soldered onto the buccal surface of an orthodontic band, which was cemented to the first upper molar in 12 patients, average age 26 years. The holes were filled with a zinc phosphate (Phosphate Kulzer), a glass ion...

The effects of oral environment stabilization procedures on counts of Candida spp. have rarely been discussed, and no conclusive results are found in the literature. The aim of this study was thus to ascertain the effects of oral environment stabilization procedures with glass ionomer and zinc oxide-eugenol cements on counts of Candida spp. in the oral cavity of children. For this purpose, oral...

Direct pulp capping is the most conservative restorative procedure for protecting the pulp from further insult, permitting healing and repair. Calcium hydroxide Ca(OH) 2 is the most commonly used materials for direct pulp capping . The aim of this study was to compare clinically and radio graphically Ca(OH) 2 with Resin modified glass ionomer (RM-GIC) as a direct pulp capping material. Forty si...

AIM This study includes a comparative evaluation of the various surface treatments of the intaglio surface of crowns in combination with various luting agents for maximal retention. MATERIALS AND METHODS Totally, 150 dies of a standard complete crown preparation were fabricated. Wax pattern with a loop on the occlusal surface was prepared on each die using standard procedures, and then crowns...
