“…On the other hand, its physicochemical bonding to dentin could have inhibited bacterial percolation through the tooth/restoration interface [Dionysopoulos et al, 1994;ten Cate and van Duinen, 1995;ten Cate et al, 1995;Mertz-Fairhurst et al, 1995;Francci et al, 1999].…”

With the purpose of checking, in vivo, the effect of atraumatic restorative treatment (ART) on the remaining demineralized dentin, 12 primary molars with deep occlusal lesions from children with ages ranging from 3 to 7 were evaluated. After lesion excavation, and before glass ionomer cement placement, dentin samples were collected from the pulpal wall of the cavity. After 3 months, the restorations were removed and new samples were collected. Six microareas of each sample were analyzed by X-ray energy dispersion spectrometer. Samples obtained before treatment were infected and intertubular dentin had a loosely organized collagen matrix, with well-defined collagen fibers. Following treatment, in addition to a drastic reduction of the amount of bacteria, the intertubular dentin was denser, with more compact and closely packed collagen fibers. An increased calcium concentration was observed in dentin collected after treatment (p < 0.001), suggesting tissue remineralization, but fluoride was not detected. We conclude that ART allows a one-session approach, with the purpose of creating more favorable conditions for the healing process.

“…10 The high-fluoride release and recharge properties of giomers minimize recurrent caries and demineralization. 11 Based on several studies, [12][13][14][15][16] giomers have a reported caries inhibiting effect of 14%-35% compared to nonfluoride-releasing restorative materials.…”

Giomer restoratives, like other direct and indirect composites, are softened by foodsimulating liquids, especially citric acid and ethanol. They are also roughened by citric acid. SUMMARYThis study examined the effects of food-simulating liquid (FSL) on the hardness and roughness of giomer restoratives based on prereacted glass ionomer (PRG) technology. The materials investigated included a regular (Beautifil II [BT]) and a recently introduced injectable (Beautifil Flow Plus F00 [BF]) hybrid PRG composite. A direct hybrid composite (Filtek Z250 [ZT]) and an indirect hybrid composite (Ceramage [CM]) were used for comparison. The materials were placed into customized square molds (5 mm 3 5 mm 3 2.5 mm), covered with Mylar strips, and cured according to manufacturers' instructions. The materials were then conditioned in air (control), distilled water, 50% ethanol solution, and 0.02 N citric acid at 378C for seven days. Specimens (n=6) were then subjected to hardness testing (Knoop) and surface profilometry. Data were analyzed using one-way analysis of variance and post hoc Scheffe test (p,0.05). Mean Knoop hardness values for the control group (air) ranged from 53.4 6 3.4 (BF) to 89.5 6 5.2 (ZT), while mean surface roughness values values ranged from 0.014 6 0.002 (ZT) to 0.032 6 0.001 (BT). All materials were significantly softened by FSL. The degree of soften-

“…[3][4][5] A number of studies have suggested that the fluoride released from glass ionomer cements can reduce the demineralization of the surrounding dentin or enamel and favor the remineralization of lesions close to the restoration wall. [6][7][8][9] Glass ionomer cements contain calcium fluoroaluminosilicate glass, which is attacked by polyacids to release cations and fluoride ions. These ions react with polyanions to form a salt gel matrix that presents small particles of silica gel containing fluoride crystallites.…”

TR Aguiar CF Pinto V Cavalli M Nobre-dos-Santos GMB Ambrosano P Mathias M Giannini Clinical RelevanceWithin the limited experimental conditions, the self-adhesive cements provided fluoride ion release capacity. The fluoride release for all resin cements was not uniform during pH cycling, decreasing throughout the duration of the study. SUMMARYThis study evaluated the effects of curing modes and storage conditions on fluoride release of resin cements. In phase 1, the cumulative fluoride release rate from samples of the resin cements (Panavia F 2.0, RelyX Unicem, MaxCem, and BisCem) was quantified after 15 days storage in water (n=4). In phase 2, the fluoride release profiles from the same materials were analyzed during pH cycling (n=4). In this second phase, fluoride was measured at specific times (one, two, three, five, eight, and 15 days). Disk-shaped specimens were prepared (10 mm 3 0.5 mm), and the materials were either light activated or allowed to autopolymerize. For both phases, the fluoride release was measured using a fluoride ion-specific electrode. The fluoride release in water was not affected by the curing mode of RelyX Unicem and Maxcem resin cements. Panavia F. 2.0 and BisCem resin cements, either light cured or autopolymerized modes, released higher amounts of fluoride in water than the other self-adhesive cements. In phase 2, the concentration of fluoride released decreased from the first day of pH cycling until the 15th day for all resin cements, for both curing modes, regardless of the storage solution used (demineralizing/remineralizing). The fluoride release rate during pH cycling by Panavia F 2.0 and MaxCem was not affected by the curing mode. The effect of the curing mode on fluoride ion release in water or during pH cycling was product dependent.
