“…As mentioned above 4,10) , slight demineralization was noted after a long-term exposure to acid in the ICON coated group. This might be due to incomplete embedding of enamel minerals in the lesion body, or due to the resin shrinkage during light curing 20) . However, the limited acid penetration was considered sufficient for arresting the incipient enamel lesion in vivo.…”

“…Earlier studies found that the resin with high penetration coefficients could penetrate deeper inside the lesion 20,21) . The ICON resin monomer (TEGDMA) contains no functional group in the molecule to exert strong chemical bonding performance to the apatite surface such as esterized phosphate, e.g., methacryloyloxydecyl dihydrogen phosphate (MDP) 22) and carboxy groups e.g., 4-methacryloxyethyl trimellitate anhydride (4-META) 23) .…”

Effect of thermal cyclic stress on acid resistance of resin-infiltrated incipient enamel lesions in vitro

et al. 2016

This study aimed to examine the effect of thermal cycling on gap formation at the interface between infiltrated resin (ICON ® ) and enamel lesion and on the durability of anti-demineralization efficacy to predict the future performance. SS-OCT technique was examined to determine whether it has the potential to detect the gap. Bovine enamel lesions were prepared, and the infiltrated resin was applied to the lesion. Resin-infiltrated lesion specimens were thermal cycled 10,000 cycles and further demineralized in pH 4.5 buffer for 7 days. Released Ca (mg/cm 2 ) was quantified by Ca electrode. The SS-OCT technique was applied to detect the gap, and SEM observation was performed to determine the presence of the gap. There was no significant difference in the amount of Ca release before and after the thermal cycling, suggesting long-lasting anti-demineralization efficacy of the resin. SS-OCT and SEM observations indicated no apparent gap formation after the thermal cycling.

“…12 High TEGDMA content and ethanol in adhesives were shown to increase the capillary penetration and wetting ability of the resins, facilitating better micromechanical unity with the enamel, whereas Bis-GMA content decreases this property, which might result in weakened plugging of the porosities. 13,16,17 On the other hand, the high TEGDMA content in the resin matrix increases polymerization shrinkage and stress, resulting in lower physical properties. Similarly, more oxygen inhibition and polymerization shrinkage of the lowviscosity caries infiltrant were reported to create heterogeneous areas within the penetrated material, resulting in insufficiently filled porosities of the surface.…”

Objective: To test the null hypothesis that combining low-viscosity caries infiltrant with conventional adhesive resins would not improve sealing of sound enamel against demineralization in vitro. Materials and Methods: Bovine enamel discs (N 5 60) with diameter of 3 mm were randomly assigned to six groups (n 5 10). The discs were etched with 37% phosphoric acid for 30 seconds and treated with resins of different monomer content forming the following groups: (1) Icon (DMG), (2) Transbond XT Primer (3M ESPE), (3) Heliobond (Ivoclar Vivadent), (4) Icon + Transbond XT Primer, and (5) Icon + Heliobond. Untreated etched samples served as the negative control. Specimens were subjected to demineralization by immersion in hydrochloric acid (pH 2.6) for 80 hours. Calcium dissolution into the acid was assessed by colorimetric analysis using Arsenazo III method at 16-hour intervals. Groups presenting high protection against demineralization were subjected to further acidic challenge for 15 days with calcium measurements repeated at 24-hour intervals. Data were analyzed by Kruskal-Wallis test and Mann-Whitney U-test. Results: Untreated specimens showed the highest amount of demineralization. Icon and Transbond XT primer decreased the mineral loss significantly compared to the control. Heliobond performed significantly better than both Icon and Transbond XT primer. Combination of Icon both with Transbond XT primer or Heliobond served as the best protective measures and maintained the protective effect for the additional 15-day acidic challenge. Conclusions: Within the limitations of this in vitro study, it could be concluded that the use of lowviscosity caries infiltrant prior to application of the tested conventional adhesives increases their protective effect against demineralization.

“…It has also been proven to significantly increase micro-hardness and reduce mineral loss after a demineralization challenge compared with untreated lesions 12) . The mechanism is that resin-infiltrant exploits capillary forces to transport resins with high penetration coefficients into enamel porosities, and after polymerization the infiltrant occludes diffusion pathways for cariogenic acids and dissolved minerals 13) . Resin-infiltrant has a significantly deeper penetration in the lesion body than conventional dental adhesives 14,15) and the diffusion barrier of caries infiltration is not formed at the lesion surface as caries sealing and coating but created inside the lesion body 16) .…”

Evaluation of resin infiltration on demineralized root surface: An in vitro study

et al. 2017

View full text Add to dashboard Cite

The aim of this study was to evaluate the effect of resin infiltration on root caries induced by Streptococcus mutans biofilms. Human premolar specimens were divided to 5 groups: negative control (NC), Clearfil SE Bond (SEB), Icon-etch120s+Icon-infiltrant (HA120), Icon-etch10s+Icon-infiltrant (HA10) and K-etchant10s+Icon-infiltrant (PA10). The resin penetration was observed by fluorescent microscope. Biofilm-induced demineralization was conducted again and observed by swept-source optical coherence tomography and confocal laser scanning microscope. The maximum resin penetration depth (PDmax), lesion depth increase (∆LD), frequency of cervical enamel loss and dentinoenamel junction separation length were measured and statistically analyzed. HA120 showed 138.00±49.25 µm PDmax that was significantly larger than PA10 and SEB (p<0.05). SEB created 136.58±64.73 µm coating layers. HA120 and SEB showed significantly lower ∆LD than NC (p<0.05). Resin infiltration with 120s-HCl pretreatment has got a good penetration ability and preventive effect on root caries, however, an additional risk factor of cervical enamel loss was identified.
