This study investigated fluoride release, acid resistance and shear bond strength (SBS) of new 4-META/MMA-TBB-based fluoridecontaining resin adhesive (Super-Bond/F3). Super-Bond, Transbond Plus and Fuji Ortho LC were selected for comparison. Fluoride release into distilled water during 6-month period was measured using disk-shaped specimens. Brackets were bonded to human premolars with each material and then the specimens for the nanoindentation test were subjected to alternating immersion (demineralizing and remineralizing solutions); the hardness and elastic modulus of the enamel around bracket were determined. Rest of the specimens was subjected to examine the SBS. Super-Bond/F3 and Fuji Ortho LC showed significantly greater fluoride release compared with the other materials. The reductions in hardness and the elastic modulus for Super-Bond/F3 and Fuji Ortho LC were lower than those for the other materilas. Super-Bond and Super-Bond/F3 showed significantly greater SBS than Fuji Ortho FC. In conclusion, Super-Bond/F3 showed high fluoride-release, cariostatic potential and equivalent SBS.

“…[7][8][9][10] Fluoride-releasing bonding agents are effective, but the amount of fluoride released from bonding agents decreases dramatically over very short periods. [11][12][13] Antimicrobial agents have been suggested as preventive agents for white spot lesions, 14 but they rely on the patient to comply with rinsing instructions. Because unfilled resin sealants do not remain on the teeth, they cannot be expected to protect the enamel surface throughout orthodontic treatment.…”

Objective: To determine how filler content and an acidic environment affect the retention of sealants placed on smooth enamel surfaces. Materials and Methods: A sample of 120 teeth was randomly divided into six subsamples. Three experimental sealants with identical formulas, with the exception of the amount of filler content (18%, 30%, 50%), were applied according to manufacturers' recommendations. Half of the subsamples were exposed to an acid environment (pH of 2.5) for 96 hours. With the use of a toothbrushing simulator, each tooth was exposed to 15,000 brushing strokes, while a slurry of 1:3 toothpaste/neutral sodium bicarbonate cycled through the machine. Initial and final photographs were analyzed subjectively and objectively. Scanning electron microscope photomicrographs were used to evaluate the tooth surface. Results: Subjective analyses showed significant (P , .05) filler effects, with the 18% filled sealant showing the least change, followed by the 30% sealant, then the 50% filled sealant, which showed the greatest loss. Objective analyses showed the same pattern of loss, but the differences between sealants were not statistically significant. Exposure to an acidic environment had no significant effect on sealant retention. SEMS showed a layer of sealant remaining on all of the sealed teeth evaluated. Conclusions: Filler content of resin sealant material affects the retention of sealants on smooth enamel surfaces; exposure to an acid environment has no effect on sealant retention. Within the limits of this study, highly filled resin sealants once saturated have the ability to endure the oral environment and remain on a smooth enamel surface, regardless of the amount of filler content.

“…1 While glass ionomer cements have high levels of fluoride-releasing ability, which plays an important role in preventing the demineralization of enamel, they show poor bracket bond strength. 2 Over the past decade, resin-modified glass ionomer cements (RMGIC) with improved bracket bond strength have been developed. 3,4 The cariostatic potential of adhesives adjacent to brackets has been investigated both in vitro 1,5,6 and in vivo 7,8 by quantifying the depth of demineralization and mineral loss by various evaluation methods.…”

Objective: To determine if a new experimental resin-based material containing Portland cement (PC) can help prevent enamel caries while providing adequate shear bond strength (SBS). Materials and Methods: Brackets were bonded to human premolars with experimental resinbased adhesive pastes composed of three weight rations of resin and PC powder (PC 30, 7:3; PC 50,5:5; PC 70, 3:7; n 5 7). Self-etching primer (SEP) adhesive (Transbond Plus) and resinmodified glass ionomer cement (RMGIC) adhesive (Fuji Ortho FC Automix) were used for comparison. All of the bonded teeth were subjected to alternating immersion in demineralizing (pH 4.55) and remineralizing (pH 6.8) solutions for 14 days. The SBS for each sample was examined, and the Adhesive Remnant Index (ARI) score was calculated. The hardness and elastic modulus of the enamel were determined by a nanoindenter at 20 equidistant depths from the external surface at 100 mm from the bracket edge. Data were compared by one-way analysis of variance and a chi-square test. Results: PC 50 and PC 70 showed significantly greater SBS than Fuji Ortho FC Automix, although Transbond Plus showed significantly greater SBS than other bonding systems. No significant difference in the ARI category was observed among the five groups. For specimens bonded with PC 50 and PC 70, the hardness and elastic modulus values in most locations were equivalent to those of Fuji Ortho FC Automix. Conclusions: Experimental resin-based bonding material containing PC provides adequate SBS and a caries-preventive effect equivalent to that of the RMGIC adhesive system.
