“…25,26 ARI scores of 4 and 5 are clinically advantageous in the debonding process because this means less adhesive adhering to the tooth, resulting in easier and faster removal and minimum destruction. 27,28 This study can conclude that desensitizing agents were able to increase the SBS of the orthodontic metal bracket post-in-office bleaching, with fluoride-based desensitizing agents having better SBS than non-fluoridebased desensitizing agents. The ARI scores were similar for all groups, meaning that adhesive materials adhere more to the bracket than the enamel surface.…”

Background: Nowadays, many patients wanting to bleach and do orthodontic treatment simultaneously, in-office bleaching is more favorable because of the instant results. However, in-office bleaching procedures result in severe enamel surface demineralization and decreasing the attachment of the orthodontic bracket. Applying a desensitizing agent after in-office bleaching can remineralize the enamel surface. There are two types of desensitizing agents: Fluoride-based and non-fluoride-based. Purpose: This study aims to analyze the effect of applying fluoride-based and non-fluoride-based desensitizing agents after in-office bleaching on orthodontic brackets. Methods: Twenty-seven post-extraction upper premolars were divided into three groups (n=9): Control group, fluoride-based group, and non-fluoride-based group. The samples were subjected to an in-office bleaching procedure before a fluoride desensitizing agent was applied to the fluoride group and a non-fluoride desensitizing agent was applied to the non-fluoride group. Then, a brackets bonding procedure was performed on all samples. The samples were tested for shear bond strength (SBS), and the adhesive remnant index (ARI) was measured. The data was analyzed by a one-way analysis of variance on the SBS test, while the ARI scores were analyzed by the Kruskal–Wallis test. Results: The fluoride and non-fluoride groups showed a significantly increased SBS of the brackets after in-office bleaching (P < 0.05), with the fluoride-based desensitizing agent having the highest SBS score, while the ARI scores had an insignificant difference between all groups (P > 0.05). Conclusion: The application of desensitizing agents after in-office bleaching increased the metal brackets' SBS but could not change the ARI scores.

“…Results: The enamel microporosity showed significant difference between Group 1 and the other groups. There was no significant difference between Groups 2,3, and 4 (p<0.05). Although there was no significant difference between Group 3 and 4, the lowest one was in Group 4 (p>0.05).…”

“…When the pH falls below the threshold value, it can initiate the demineralization process, which is characterized by the formation of early stage of dental caries white spot lesion. 2,3 Demineralization is also a process involving the formation of enamel microporosity due to mineral loss and dissolution, for instance calcium, phosphate, and crystal apatite in particular and hydroxyapatite Ca 10 (PO 4 ) 6 (OH) 2 and collagen from the enamel prism. 4,5 Dynamic equilibrium happens within the process of demineralization and remineralization.…”

Background: White spot lesion is a demineralization process indicated by the increased of enamel microporosity. A tegillarca granosa shell contains 98.7% calcium and Vitis vinifera contains phytochemical compounds with fluoride, which has a potential to stimulate remineralization. Purpose: To analyze the Tegillarca granosa shell combination with Vitis vinifera and fluoride in decreasing enamel microporosity. Methods: The cream was prepared by combining 10% and 20% Tegillarca granosa shell with 10 grams of Vitis vinifera extract and 100 mg of fluoride. The cream was tested beforehand for viscocity and pH. Furthermore, 16 premolars were etched and divided into four groups. Group 1 was smeared with placebo (negative control) and Group 2 was smeared with casein phosphopeptide-amorphous calcium phosphate (positive control). The other groups were smeared with cream 10% (Group 3) and 20% (Group 4) Tegillarca granosa shell combination with Vitis vinifera and fluoride. Teeth were treated three times a day for 30 minutes and soaked in artificial saliva. After 14 days, the enamel microporosity was carried out using a scanning electron microscope. The data was analyzed with one-way analysis of variance (ANOVA) test followed by post-hoc least significant difference (LSD). Results: The enamel microporosity showed significant difference between Group 1 and the other groups. There was no significant difference between Groups 2, 3, and 4 (p<0.05). Although there was no significant difference between Group 3 and 4, the lowest one was in Group 4 (p>0.05). Conclusion: The cream, prepared by combining Tegillarca granosa shell with Vitis vinifera and fluoride, is effective in decreasing the enamel microporosity.

“…The traditional method for treating WSLs is to remineralize incipient lesions with the use of fluoride (9,11) . Recently different remineralizing agents have been developed to remineralize the incipient lesions, among of these are: -Casein phosphopeptide-amorphous calcium, phosphate (CPP-ACP) gels which is a recent remineralizing agent (12) Casein is a phospho protein derived from Cow milk and can stabilize amorphous Calcium phosphate (13) that can release high concentration of Calcium and phosphate ions, those ions can freely diffuse to enamel subsurface lesions to promote remineralization (14) Bioactive glass is another remineralizing agents which composed of Sio 2 , Na 2 O, CaO and P 2 O 5 developed by Professor Larry Hench which is commercially produced in the form of Novamin Tm (14)(15) .…”

Aim: to assess the effect of three different remineralizing agents on the shear bond strength (SBS) of orthodontic brackets bonded to remineralized enamel.Materials and Methods: 32 human premolars were allocated into four groups (n=8), covered with nail varnish except labial enamel left uncoated, demineralization protocol was performed for all groups, then remineralizing regime were applied as follow (group I) demineralization only, (group II) casein phosphopeptide amorphous calcium phosphate [CPP-ACP], (group III) Novamin, (group IV) Self-assembling peptide P11-4 (SAP-P11-4). After bracket bonding, shear bond strength was assessed. Adhesive remnant index (ARI) was detected using stereomicroscope. Kruskal-wallis test followed by Dunn's post hoc test (P<0.05) was carried out for SBS, Shapiro-Wilk 'test and Levene's test were used to test normality and homogeneity respectively and on-way ANOVA test (P<0.05) for ARI evaluation.Results: SAP P11-4 group showed significant low SBS results than the other groups while CPP-ACP and Novamin group showed significantly higher bond strength than the other two groups. Conclusion.Pretreatment of demineralized enamel surface with CPP-ACP and Novamin before bracket cementation significantly increase shear bond strength.
