“…Comprehensively, our results highlight 65,35% of overall enamel lesions were filled with resin, and the longer the application time, the greater the average penetration depth. Our results are in fully agreement with the literature [43,50,77].…”

“…Resin infiltration technique is a minimally invasive therapy to WSLs [78] with a preetching phase onto the lesion to improve penetration ability [28,77]. In addition, this penetrative role is enhanced by its methacrylate-based resin matrix containing BisGMA (bisphenol A diglycidil dimethacrylate) and TEGDMA (triethylene glycol dimethacrylate) [43,49], which confer low viscosity to the resin [35].…”

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.

“…Remineralization was used to evaluate the effects of the different treatment modalities as it offers the opportunity to effectively monitor caries-prevention on dental hard tissues on a short-time basis, thus simulating a best treatment option this is in consistence with study conducted by Tschoppe etal (24) .While the second demineralization simulated the acidic challenge was performed by using the same demineralizing protocol used for inducing caries-like lesions to evaluate the stability of the treated lesions this is in agreement with Torres et al4, Elkasass et al (19) The results of the present study revealed that the mean surface microhardness and surface microhardness recovery of Resin infiltrant agents was the highest significant values compared to other groups. This result is in agreement with previous studies conducted by Arslan et al (20) , Liuet al (25) , Attia (26) , Ahmed (27) and AbdEllahy et al (28) they concluded that Icon resin infiltration is significantly superior to fluoride varnish treatment. Resin infiltration is dependent on the occlusion and impregnation of the pores within the body of the caries lesion by replacing lost minerals with low light curing resin as reported in study by Paris, (29) so the infiltrant is soaked into the lesion body and occludes diffusion pathways for acids and dissolved minerals.…”

Aim : The present study was carried out to compare between non-invasive treatment modalities using (fluoride varnish (FV) and Nano-HAP based reminerlizing agents) and minimal-invasive treatment modalities using (resin infiltrant materials) on surface micro-hardness, surface topography and colour stability of WSLs. Methods A total 80 sound human permanent premolars were used in this study. The specimens were divided into four equal groups 20 teeth for each group. According to treatment modality group A 0 : resin infiltration material, group A 1 nano hydroxyapatite based remineralizing agent, group A 2 fluoride varnish and group (A 3 ) artificial saliva as control group. The surface microhardness (SMH) of each specimen was assessed using Vickers microhardness tester. Scanning electron microscope were used to assess surface morphological characters of enamel surface at different stage. Color stability of enamel surface at different stage were assessed by spectrophotometer. Results. Both resin infiltration material and Nano hydroxyapatite based remineralizing agents showed the highest statistically significant mean surface microhardness values and highest statistically significant mean of color stability Conclusion: Nano hydroxyapatite based remineralizing agent and resin infiltration system are the most effective treatment modalities for incipient carious enamel lesions.
