“…Furthermore, the methodology to create a cavity after caries development and its removal, described in the present study, is closer to the clinical operative procedure than the cavity preparation made in sound dentin, as reported in several studies. 3,10,21,22 The area (10,000 mm 2 ) to evaluate the mineral distribution along the interface by m-EDX analysis was selected because the fluoride ions released from adhesive systems can diffuse into dentin up to 30 mm from the interface, 4 the IZ thickness created by fluoride adhesive systems ranges from 1 to 17 mm thickness 2,5,6 and the monomer MDPB does not leach out from the material, 13 thus its antibacterial effect can be restricted to the interface. The results of the present study showed that the IZ formation and its mineral distribution were influenced by artificial caries methods and adhesive systems.…”

“…The in vitro secondary caries tests and evaluation methods have been developed that assess demineralized lesions and inhibition zones of dentin due to acid challenge. These methods include polarized light microscopy 7,8,9) , a microhardness test 8,10,11) , microradiography 5,12) , confocal laser-scanning microscopy and the x-ray analytical microscope 13,14) . However, the magnification of such methods is limited if more detailed information at the interface between the cavity and restoration is required.…”

The purpose of this study was to evaluate dentin bond strengths and to observe the adhesive-dentin interface after acid-base challenge using fluoride-free and fluoride-releasing self-etching adhesive systems; Clearfil SE Bond (SE), FL-Bond (FL) and FL-Bond II(FL II). Fifteen dentin surfaces from human molars were ground and bonded with one of three adhesive systems. The microtensile bond strength (µTBS) test was performed at a crosshead speed of 1 mm/min. The interface of the bonded specimens after acid-base challenge were also examined by a SEM.The µTBS of SE were significantly higher than those of FL and FL II (p<0.05), however, there were no significant differences between FL and FL II (p>0.05). An acid-base resistant zone (ABRZ) was observed in all the groups, however, formation of the ABRZ was material dependent. Fluoride-release from the adhesive is a key factor to create thick ABRZ.

“…For in vitro assessment of caries inhibition around restorative materials, methods such as polarized light microscopy 4) , microradiography 5) , and confocal laser scanning microscopy 6,7) have been used. However, the extent of magnification to which these methods permit is limited if more detailed information at the restoration-cavity interface is required.…”

The purposes of this study were twofold, namely to evaluate: (1) the effect of hybridization on microtensile bond strength (μTBS) to dentin, and (2) the ultrastructure of the dentin-adhesive interface with 4-META/MMA-TBB resin after acid-base challenge. Dentin surfaces, which received no treatment (NT), 65% phosphoric acid (PA), or 10% citric acid-3% ferric chloride (10-3), were bonded with a 4-META/MMA-TBB resin. To evaluate dentin bond strength, μTBS test was performed at a crosshead speed of 1 mm/min. For ultrastructural evaluation of the adhesive interfaces, SEM was used to examine the interfaces of the bonded specimens after acid-base challenge. The μTBS of NT was not determined, while that of 10-3 was significantly higher than that of PA (p<0.05). With PA and 10-3, the hybrid layer was clearly observed, but no so for the acid-base resistant zone. Wall lesion was found in NT only.In conclusion, hybridization is vital to improving μTBS to dentin and enhancing resistance at the adhesive interface against acid-base challenge.
