The effect of a bioglass paste on enamel exposed to erosive challenge

Remineralizing effect of cold plasma and/or bioglass on demineralized enamel

“…Further, it was found that, close to the surface (30-μm deep), the VHN of the bioglass groups was higher than that of the F group after 24 h of remineralization, although only the bioglass group with prior plasma treatment (PB) had significantly higher VHN values. The micro-hardness results were in accord with Bakry et al 5) , who also found that eroded enamel specimens treated with bioglass were significantly higher in VHN than those treated with 24 h fluoride at 30-and 40-μm depths.…”

“…For example, Milly et al 29) showed that surface treatment with bioactive glass and polyacrylic acid enhanced the remineralization of artificial enamel white spot lesions, as demonstrated by the improved mechanical properties, higher phosphate content and morphological changes within the lesions. Also, by mixing bioglass with phosphoric acid and applying the resulting paste to eroded enamel surfaces, Bakry et al 5) were able to improve the micro-mechanical properties of the eroded enamel within a short time.…”

“…Inspired by the use of bioactive materials for bone repair and regeneration, the potential of bioglass materials for repairing dental tissues is attracting increased interest 4) . Recently, a 45S5 bioglass-containing paste that could release calcium and phosphate ions was shown to be capable of penetrating and remineralizing enamel that had been subjected to an erosive challenge 5) . The bioglass paste formed a calcium phosphaterich layer on enamel surfaces within 24 h. This layer showed resistance to abrasion and transformed into hydroxyapatite crystals after 14 days of storage in a remineralizing solution.…”

Three-dimensional profilometric assessment of early enamel erosion simulating gastric regurgitation

“…Future studies are needed to complement the data on profilometric changes from early erosion with changes in physical and chemical changes of the tooth structures using established and evolving techniques [51][52][53][54][55][56][57][58] in order to provide an holistic assessment of early erosion process. Such an approach will enable quantitative data to be gathered on enamel softening, together with qualitative observations of increased porosity in partially lost and demineralized hydroxyapatite crystals (as displayed in stages 2, 3 and 4 in Fig.…”

Novel evaluation and treatment techniques for white spot lesions. An in vitro study

“…The bioactive treatment of erosive and sub‐surface enamel lesions by 45S5 bioglass was previously suggested . 45S5 bioglass undergoes a series of interactions in an aqueous environment that leads to formation of a hydroxyapatite layer upon storage in saliva for 2 weeks . Moreover, a paste composed of bioglass and phosphoric acid was used to occlude the dentinal tubules by forming an interaction layer, which aids in treatment of dentin hypersensitivity .…”
