Objectives: To achieve in vitro remineralization of enamel white spot lesions (WSLs) via a mesoporous delivery system of amorphous calcium phosphate (ACP) precursors.Materials and methods：Amine-functionalized expanded pore mesoporous silica (aMSN) was loaded with polyacrylic acid-stabilized amorphous calcium phosphate (PAA-ACP) to develop a carrier-based delivery system (PAA-ACP@aMSN). Thirty-six artificial WSLs samples were created and randomly assigned to three treatments: artificial saliva solution (negative control, n = 12), casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) slurry (n = 12), and PAA-ACP@aMSN slurry (n = 12). Surface microhardness, Raman intensity, and color were measured before/after artificial demineralization and after remineralization treatments to evaluate the remineralization level of each sample. SEM images were taken on the surface and cross-section of samples to observe microstructure changes.Results：The surface microhardness recovery ratio (%SMHRR), Raman intensity change ratio (%ICR), and color recovery ratio (%CRR) were not significantly different between CPP-ACP and PAA-ACP@aMSN groups (P > 0.05), but both of them had significantly higher %SMHRR, %ICR, and %CRR values than negative control (P < 0.01). SEM images showed that apparent enamel prism imprints and inter-prism gaps in negative control were masked by mineral deposition in the PAA-ACP@aMSN and CPP-ACP groups.Conclusions: PAA-ACP@aMSN has an ability to remineralize enamel WSLs.Clinical relevance: The carrier-based amorphous calcium phosphate delivery system has great potential to serve as a remineralizing agent for the treatment of WSLs.

“…The L parameter represents the color's lightness [40]. Many studies have shown that creating the wsl raises the whiteness of the tooth by affecting the absorbing light in that region, implying the treatments' influence on the teeth's brightness [41]. In comparison to the peptide group, our findings show that the groups F-LLLT and BAG had a significant reduction in tooth color.…”

Novel Technology for Enamel Remineralization in Artificially Induced White Spot Lesions: In Vitro Study

The enamel white spot lesion is a common complication of orthodontic treatment with a high prevalence. This research aims to create an artificially induced white spot lesion, evaluate three different commercial products in terms of visual appeal, mineral reestablishment, and roughness, and determine which material can recover the initial structure. We created an artificially induced white spot lesion in extracted teeth. The materials used in the study were peptide p11-4 (CurodontTM Repair, Credentis AG), bioactive glass toothpaste (Biomin F, BioMin Technologies Limited), and local fluoridation (Tiefenfluorid, Humanchemie) in conjunction with low-level laser therapy (LLLT). To objectively assess the surface, the roughness, mineral content, and esthetic were measured. The roughness increased with a median difference of −0.233 µm in the bioactive glass group; the color parameter delta L decreased dramatically with a median difference of 5.9–6.7; and the cervical third increased the Ca-P mineral content above the starting stage. Each material contributed significantly to enamel consolidation, with peptide therapy providing the most encouraging results.

“…On the tooth treated with the abrasive erosion technique, the surface underwent heterogeneous abrasion on which a surface layer persisted without any type of etching pattern that would allow the infiltration by any type of resin (Figure 18). As in other studies [41,46,47,49], both teeth were analyzed under an electronic microscope in order to examine the surface characteristics produced by the chemical erosion and abrasive erosion processes. We observed that the tooth treated with chemical erosion presented an etching pattern with complete erosion at the centers of the enamel prisms.…”

Dental Treatment of White Spots and a Description of the Technique and Digital Quantification of the Loss of Enamel Volume

et al. 2020

The prevalence of white spots on teeth has increased in recent years. Regardless of their etiology, these lesions are characterized by a reduction in the enamel’s mineral phase, which is replaced by organic fluids. This causes an alteration of its chemical composition that affects its optical characteristics. Subsurface demineralization increases the pore volume of enamel, which in turn changes its optical refraction and results in the opaque color of white spot lesions. Here, we examined a non-invasive clinical technique used for eliminating these white spot lesions from enamel via two HCl-based products at different concentrations (6.6% and 15%). We used a digital method for evaluating the volumetric changes produced in dental enamel by the application of both products, one of which involved chemical erosion and the other, abrasive erosion. The mean volume of the enamel eliminated was −0.042 mm in 15% HCl, and −0.12 mm in 6.6% HCl. Thus, both 15% HCl and 6.6% HCl are capable of eroding the surface of the tooth enamel without reaching dentin. Moreover, 6.6% HCl produced a greater erosion of the dental enamel and left the surface a texture typical of an abrasive chemical-erosive product. The 15% HCl, however, produced an etching pattern typical of an erosive chemical with open enamel prisms prepared for subsequent adhesive procedures and restorers.
