“…34 Ourcolor results came in agreement with those of Bak et al 25 and Yetkiner et al 35 who proved the ability of resin infiltrant to resist thermal and discoloration challenges. Regarding surface roughness, our results agreed with previous studies [36][37][38][39][40] which concluded that resin infiltration of enamel lesions can provide and maintain smoother surface. However, these results contrast those of other researches [41][42][43] which reported that surface roughness and color stability of resin-infiltrated enamel lesions were less than ideal and could further recede with aging in the oral environment.…”

Objective To investigate the ability of resin infiltration to protect demineralized enamel against acidic challenge. Materials and methods Forty‐five extracted healthy premolars were selected for the study, each of which was sectioned vertically into 2 halves, giving 90 specimens. Specimens were then divided into three groups, where specimens of group A were not decalcified (control), while those of groups B and C were either subjected to decalcification only, or decalcification followed by Icon resin infiltration, respectively. Each group was further divided into three subgroups, according to the type of storage medium (water, Coca‐Cola, or Redbull). Evaluation parameters included color difference and surface roughness. Scanning electron microscope was used to evaluate enamel surface topography. Statistical analysis was performed by ANOVA followed by least significant difference test. Results Although Coca‐Cola caused the highest color change and surface roughness among the studied specimens, yet, the resin‐infiltrated enamel was more resistant to surface changes than the nonresin infiltrated enamel, even under acid attack. Conclusion Resin infiltration has the ability to provide and maintain protection to the demineralized enamel against acidic attack. Clinical significance Resin infiltration may be considered as a promising solution to restore esthetic of demineralized enamel following orthodontic treatment and to protect it against acidic beverages.

“…The increased surface roughness observed on the resin-infiltrated lesions with aging in the present study, may be attributed to internal and thermal stresses generated by water sorption and thermal expansion and contraction. 19 The present results agreed with former studies [30][31][32] which reported the ability of resin infiltrants to provide and maintain smoother enamel surface. However, other studies 19,33,34 came in contrast, as they reported that surface roughness of resin-treated enamel lesions were not ideal and might further recede with aging.…”

Introduction:Resin infiltration technique is a promising option for treatment of incipient enamel lesions, especially for patients with history of fixed orthodontic appliances. However, its ability to resist aging under thermal influences in the oral cavity is still questionable. Aim of the study: The present research aimed to inspect the ability of resin-infiltrated initial enamel lesions, to resist aging under thermal challenge. Materials and methods:Fifty extracted non-carious premolars were included in the present study. Specimens were equally distributed into 5 groups, where group 1 included teeth with sound enamel (control), while group 2 included teeth with decalcified untreated lesions. Specimens of group 3 were subjected to Icon® resin infiltration after decalcification. For groups 4 and 5, decalcified resin-infiltrated specimens were subjected to thermocycling (TC) at 5,000 or 10,000 cycles respectively. Surface evaluation parameters included surface microhardness and roughness. Surface morphology was further evaluated using scanning electron microscope (SEM). For statistical analysis, ANOVA and LSD tests were used.Results: Resin-infiltrated enamel was more resistant to surface changes, under thermal stresses, than the non-resin-infiltrated enamel. The resin surface showed high resistance to surface degradation at thermal stress of 5000 cycles, while more deterioration started to appear at 10,000 cycles. Conclusion:Resin infiltration has the ability to provide adequate protection to the demineralized enamel against thermal attack of 5,000 thermal cycles. However, surface microcracks generated at 10,000 thermal cycles indicate that the material might further deteriorate on aging for more than one clinical service year.

“…Indeed, internal infiltration obviously should be the first step, and occlusion of the tiny pores might even be enhanced by applying active pressure with the aid of packable composite resins prior to polymerization [75]. The infiltrant resin used in the present investigation (Icon Caries Infiltrant; DMG) has been shown to be compatible to generally utilized adhesive restorations [32,76], and does not impair the shear bond strengths to dentin [77], while adhesion to sound [78][79][80] or demineralized [40,78,80,81] enamel even was increased (if compared to other adhesive systems); moreover, tensile bond strength testing was accompanied by a high portion of mixed (cohesive in enamel) failures [80], thus indicating a strong and reliable enamel hybrid layer composed of resin tags enveloping the enamel crystallites [82]. These aspects obviously indicate that final composite resin restorations can be bonded adhesively to the resin-infiltrated hard substances, and this should result in stable repairs, thus complying with the concepts of minimum intervention dentistry [1,2], and solving (or at least minimizing) some of the clinical problems discussed above.…”

“…Indeed, previous papers have clarified that both the tendency of surface breakdown [33,34] and the ICDAS codes [35,36] will increase with advanced radiographic lesion extensions. Due to the material's inherent mechanical properties [37], the infiltration approach using an unfilled and low-viscosity resin will not be able to completely fill up any (micro-)cavitations [2,3,38], nor will it be able to adequately smoothen the infiltrated surface of demineralized (and rough) enamel [39]; thus, several investigations have clearly elucidated that roughness of infiltrated lesions will remain increased if compared to sound enamel [18,20,21,25,40], and this will not be perfectible by various polishing procedures [41]. Rough surfaces (with R a values exceeding 0.2 μm as the critical threshold), however, are susceptible to facilitate biofilm accumulation, and this has been revealed for infiltrated surfaces as well, even if to a lesser extent if compared to non-infiltrated lesions [17,19,42].…”

This ex vivo proof-of-concept study aimed to investigate the effect of nanosilver particles (AgNP) added to a conventional infiltrant resin (Icon) on external penetration into natural proximal enamel caries exceeding into dentin after internal tunnel preparation and internal infiltration. Carious lesions (ICDAS codes 2/3) of extracted human (pre-)molars revealing proximal caries radiographically exceeding into dentin (E2/D1 lesions) were preselected. Then, 48 of those specimens showing demineralized areas transcending the enamel-dentin border as assessed by means of near-infrared light transillumination (DIAGNOcam) were deproteinized (NaOCl, 5%). Using an internal tunnel approach, occlusal cavities central to the marginal ridge were prepared. Excavation of carious dentin, total etch procedure (H 3 PO 4 , 40%), and internal resin infiltration (FITC-labeled) followed, along with final restorations (flowable composite resin). Outer lesion surfaces were etched (HCl, 15%) prior to external infiltration (RITC-labeled). Group 1 (control; n = 24) used non-modified infiltrant, while an infiltrant/ AgNP mixture (20 nm; 5.5 wt%) was used with experimental Group 2 (n = 24). Non-infiltrated pores of cut lesions were stained (Berberine), and specimens were analyzed using confocal laser scanning microscopy. Compared to the non-filled infiltrant, incorporation of AgNP had no effect on the resin's external penetration. Between the groups, no significant differences regarding internal or external infiltration could be detected, and non-infiltrated lesion areas did not differ significantly (p>0.109; t-test). The internal tunnel preparation in combination with both an internal resin infiltration and an additional external infiltration approach using a nanosilver-modified infiltrant resin leads to increased infiltrated lesion areas, thus occluding and adhesively stabilizing the porous volume of the demineralized enamel. While exerting antimicrobial effects by the nanosilver particles, this approach should have the potential as a viable treatment alternative for proximal lesions extending into dentin, thus avoiding the sacrifice of sound enamel, postponing the frequently inevitable restoration/re-restoration cycle of conventional proximal caries treatment, and improving dental health.
