“…In this systematic review, twenty-three articles reported information about microhardness , ten evaluated surface roughness, [27,31,37,47,[49][50][51][52][53][54], sixteen assessed the penetration depth [40,46,50,[55][56][57][58][59][60][61][62][63][64][65][66][67] and eight explored shear bond strength after resin infiltration [32,52,[68][69][70][71][72][73].…”

“…Overall, twelve studies included bovine teeth (n per group = 803) while twenty-five studies included human teeth (n per group = 865). Nine studies reported data without specimen demineralization previously to resin infiltration [47,54,55,57,59,[61][62][63][64]74] and thirty-nine articles included the demineralization process before the infiltrative resin [21,[27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][48][49][50][51][52][53]56,58,60,[65][66][67][69][70][71][72][73]. The demineralization process consists of emerging the teeth in a demineralization solution, with pH between 4 and 5 for a period of time that ranges from 1 min to 1200 h, to simulate the formation of WSLs (Table…”

Subsurface enamel demineralization beneath an intact surface layer or white spots lesions (WSL) can and should be treated with non-invasive procedures to impede the development of a cavitated lesion. We aim to analyze if infiltrative resin improves enamel roughness, microhardness, shear bond strength, and penetration depth. MEDLINE [via Pubmed], Cochrane Central Register of Controlled Trials, Embase, Web of Science, Scholar, and LILACS were searched until May 2021. Methodological quality was assessed using the Joanna Briggs Institute Clinical Appraisal Checklist for Experimental Studies. Pairwise ratio of means (ROM) meta-analyses were carried out to compare the enamel properties after treatment with infiltrative resin on sound enamel and WSLs. From a total of 1604 articles, 48 studies were included. Enamel surface roughness decreased 35% in sound enamel (95%CI: 0.49–0.85, I2 = 98.2%) and 54% in WSLs (95%CI: 0.29–0.74, I2 = 98.5%). Microhardness reduced 24% in sound enamel (95%CI: 0.73–0.80, I2 = 99.1%) and increased by 68% in WSLs (95%CI: 1.51; 1.86, I2 = 99.8%). Shear bond strength reduced of 25% in sound enamel (95%CI: 0.60; 0.95, I2 = 96.9%) and increased by 89% in WSLs (95%CI: 1.28–2.79, I2 = 99.8%). Penetration depth was 65.39% of the WSLs (95%CI: 56.11–74.66, I2 = 100%). Infiltrative resins effectively promote evident changes in enamel properties in sound and WSLs. Future studies with long-term follow-ups are necessary to corroborate these results from experimental studies.

“…In this study, higher SBS values were obtained in the intact enamel group than in the demineralized enamel group, in accordance with previous studies, but the difference was not statistically significant. However, Gulec and Goymen also found no statistically significant difference between the SBS values of brackets placed on the intact enamel surface and the demineralized enamel surface (32). One reason for these different results may be that different demineralization protocols were applied.…”

“…Consistent with previous studies (28,31,35), our study found that the use of ICON and CPP-ACP on the demineralized enamel surface increased the SBS strength of the brackets, but there was no statistically significant difference when these two groups were compared with the intact enamel surface and demineralized enamel surface groups. Gulec and Goymen found that ICON and CPP-ACP applied to the demineralized enamel surface had brackets with SBS values lower than those on the intact enamel surface and those directly adhered to the demineralized enamel surface (32). Some reasons for this difference may include the application time of the pretreatment agents, the different waiting times in the artificial saliva solution, the use of thermal cycles and the development of bonding agents or bracket retention properties.…”

Aim: The aim of this in vitro study was to measure the effects of white spot lesions treatment agents on the shear bond strengths (SBSs) and adhesive residual indexes (ARIs) of orthodontic brackets. Methodology: This study used 100 human premolar teeth randomly divided into five groups. Group 1 comprised those with intact enamel, Group 2 comprised those with demineralized enamel and Groups 3–5 comprised those demineralized enamel that was treated with casein phosphopeptide amorphous calcium phosphate fluoride (CPP-ACPF), fluoride varnish and a resin infiltrant, respectively. Brackets were bonded to the teeth using the conventional method, then the samples were thermocycled and tested for SBS using a universal testing machine. The adhesive remnant indexes (ARI) of the brackets were also evaluated. One-way ANOVA and post-hoc Tukey tests were used to compare the groups’ SBSs and the Kruskal–Wallis test was used to evaluate the groups’ ARI scores. Results were considered statistically significant if p was less than 0.05. Results: Statistically significant differences were found between the groups (F was 6.895 and p was less than 0.001). The SBSs of the brackets in Group 4 were significantly lower than those of the other groups (the mean was 13.44 ± 6.37 MPa). Group 5 had the highest mean SBS value (22.11 ± 6.56 MPa). Additionally, the ARI scores of the four groups were significantly different (p was less than 0.001). Conclusion: Resin infiltration and CPP-ACPF applications can improve bonds to demineralized enamel, while fluoride varnish applications are not recommended for such enamel.

“…The protective effect of resin infiltrant on sound tooth enamel provides a new attempt on prevention of dental caries, which may be used in preventing dental caries in people at high caries risk, such as patients who will undergo orthodontic treatment. According to reports, the incidence of white spot lesions in patients who have not undergone orthodontic treatment is between 11–24% ( Gulec & Goymen, 2019 ). The prevalence of white spot lesions after treatment fixed orthodontic appliances is 23%, 50% or even 97% ( Kobbe et al, 2019 ).…”

Objective To investigate the effect of resin infiltrant on resistance of sound permanent enamel surfaces to demineralization. Method Eighty healthy premolars were sectioned to obtain enamel blocks from the buccal surface. Specimens with baseline surface microhardness values of 320–370 were selected. The experimental group were treated with resin infiltrant, while the control group was not. Specimens from each group were artificially demineralized and the surface microhardness values were measured again. Confocal laser scanning microscopy was used to measure the depth of demineralization and detect the penetration ability of the resin infiltrant. The specimens were subjected to a simulated toothbrushing abrasion test. Scanning electron microscopy was used to observe changes in the surface morphology of specimens after each of these procedures. Results No significant differences between the experimental and control groups were observed in the baseline microhardness values or in the experimental group after resin infiltration compared with the baseline conditions. After artificial demineralization, the microhardness value in the control group was significantly lower than that in the experimental group (266.0 (±34.5) compared with 304.0 (±13.0), P = 0.017). Confocal laser scanning microscopy results showed that the demineralization depth in the control group was significantly deeper than that in the experimental group (97.9 (±22.8) µm vs. 50.4 (±14.3) µm, P < 0.001), and that resin infiltrant completely penetrated the acid-etched demineralized area of the tooth enamel with a mean penetration depth of 31.6 (±9.0) µm. Scanning electron microscopy showed that the surface morphology was more uniform and smoother after simulated toothbrushing. The enamel surface structure was more severely destroyed in the control group after artificial demineralization compared with that of the experimental group. Conclusion Resin infiltrant can completely penetrate an acid-etched demineralized enamel area and improve resistance of sound enamel surfaces to demineralization. Our findings provide an experimental basis for preventive application of resin infiltrant to sound enamel surfaces to protect tooth enamel against demineralization.
