“…[4][5][6]15 Although this may bring a slight optical abatement of WSL within the first 12 months following debracketing, it rarely provides for an esthetically acceptable improvement in dentofacial appearance. 8,9,16 Resin infiltration of postorthodontic WSL has been shown to be more effective in achieving a clinically relevant camouflage effect with adjacent enamel, based on short-and mid-term studies, case reports and in vitro research. 8,[10][11][12]17,18 However, a common question raised by both patients and clinicians concerns the long-term durability of the results achieved.…”

“…Remineralization by local fluoride application may arrest lesion progression 3 and, in combination with tooth brushing abrasion, bring about some improvement in the appearance of WSL within the first few months following debonding, [4][5][6] however, rarely to an extent that provides for an esthetically acceptable dentofacial appearance. [7][8][9] In contrast, the technique of resin infiltration (Icon, DMG) of postorthodontic enamel decalcifications yields esthetically more satisfying results. A recent split-mouth randomized controlled trial (RCT) revealed that there was a significant and clinically relevant abatement of color-and lightness differences between infiltrated WSL and sound adjacent enamel, whereas there were no significant changes in untreated control-WSL in the same time.…”

Objectives: To reassess the long-term camouflage effects of resin infiltration (Icon, DMG, Hamburg, Germany) of white spot lesions (WSL) and sound adjacent enamel (SAE) achieved in a previous trial. The null hypothesis was tested that there were no significantly different CIE-L*a*b*-ΔE-values between WSL and SAE areas of assessment after at least 24 months (T24) compared to those at baseline (T0). Materials and Methods: Of twenty subjects who received previous resin infiltration treatment of nteeth = 111 nonrestored, noncavitated postorthodontic WSL after multibracket treatment during a randomized controlled trial and were contacted 20 months after baseline, eight subjects (trial teeth nteeth = 40; m/f ratio 1/7; age range (mean; SD) 12–17 [15.25; 2.12] years); response rate: 40%) were available for follow-up after at least 24 months (T24). CIE-L*a*b* differences between summarized color and lightness values (ΔEWSL/SAE) of WSL and SAE were assessed using a spectrophotometer and compared to baseline data assessed prior to infiltration (T0), and those after 6 (T6), and 12 (T12) months using paired t tests at a significance level of α = 5%. Results: T24 assessments were performed after a mean 33.86 (SD: 8.64; Min: 24; Max: 45) months following T0. Mean (SD) ΔEWSL/SAE units of available teeth were 8.76 (5.33) at baseline; 5.5 (2.75) at T6; 5.2 (2.41) at T12; and 5.57 (2.6) at T24. Comparisons of T6, T12, and T24 with T0 yielded highly significant differences, whereas T6–T24 and T12–T24 differences were found to be not significant. Conclusions: Assimilation of infiltrated WSL to the color of adjacent enamel by resin infiltration is considered to be suitable for the long-term improvement in the esthetic appearance of postorthodontic WSL.

“…On the other hand, Ogaard et al [ 27 ] concluded that high-concentration fluoride solutions are far more effective than low-concentration ones. Bock et al [ 28 ] studied WSL changes in response to weekly 1.25% fluoride gel application after fixed orthodontic treatment. Their results did not show any significant positive effects for high-dose fluoride on post-orthodontic WSL development.…”

An In Vitro Study on the Effect of Amorphous Calcium Phosphate and Fluoride Solutions on Color Improvement of White Spot Lesions

The ability of remineralizing agents to improve the color of white spot lesions (WSL) is an important aspect that should be investigated. The aim of this study was to evaluate the effects of 0.05% amorphous calcium phosphate (ACP), 0.5% ACP, and 0.05% fluoride solutions, as well as artificial saliva on the color improvement of white spot lesions (WSLs). In this in vitro study, 50 human premolar teeth were randomly classified into five groups. At baseline, all the samples were assessed by using a colorimeter (E0). Then, white spot lesions were induced on the surface of the teeth by means of a pH-cycling model, and the colorimeter was used again (E1). Afterwards, samples of the 1st and 2nd groups were kept in 0.05% ACP and 0.5% ACP solutions for 1 min/day, respectively. The 3rd group specimens were placed in 0.05% fluoride solution for 1 min/day. The other two groups were kept in artificial saliva and distilled in water separately. All the samples were assessed by the colorimeter for a third time (E2). We found no significant difference between the groups in ∆E1. There was also no significant difference among 0.05% ACP solution, 0.5% ACP solution, 0.05% fluoride solution, and artificial saliva considering ∆E2. However, a significant difference was noted between the above-mentioned solutions and distilled water in ∆E2. With respect to ∆E3, there were considerable differences between ACP solution and artificial saliva. The same results were obtained for the difference between fluoride solution and artificial saliva. However, no significant difference was found among 0.05% ACP, 0.5% ACP, and 0.05% fluoride solutions in terms of ∆E3. In Conclusion, ACP is as effective as fluoride in the color improvement of WSLs and the recommended treatment for this purpose is daily use of 0.05% ACP, 0.5% ACP or 0.05% fluoride solutions.

“…Although oral hygiene instructions were provided, controlling for individual behavior has been shown to be very difficult. 24 Another limitation was that only right-handed patients were accepted for the study because handedness may influence brushing efficiency. In addition, the absence of analyses of patients' plaque and gingivitis scores was another limitation of the study.…”

Objective: To determine whether total or partial etching procedures influence the appearance of white spot lesions (WSLs). Materials and Methods: This split-mouth, double-blind, controlled, randomized study included 20 patients (mean age 16.75 years), who had class I malocclusion, mild crowding, and satisfactory oral hygiene. A total of 40 maxillary quadrants were randomly allocated to be treated using a total etching (TE) or partial etching (PE) protocol. Quantitative light fluorescence images were captured at the beginning and at 3 (T1) and 6 (T2) months after beginning orthodontic treatmen, as well as when the debonding phase of orthodontic treatment was complete (T3). The presence of pre- and posttreatment WSLs was assessed with quantitative light fluorescence software and analyzed with Student's t-test. Results: The analyses showed that, at T2, the total etching group had significantly higher ΔQ and A scores than the partial etching group (P < .05). The ΔF scores increased significantly at all timepoints in the TE group, but only at T1 and T3 in the PE group. However, no differences were noted at T3 between the TE and PE groups (P > .05). The inclusion of only right-handed people may have limited the generalizability of the findings. The absence of analyses of the plaque and gingivitis scores of patients was another limitation of this study. Conclusions: WSL formation was observed mostly in maxillary lateral incisor teeth irrespective of the etching technique. Although PE seems to be more successful in the first 6 months, no difference was observed between PE and TE in the long term for WSL formation.
