ABSTRACT Aim The aim of this in vitro study was to evaluate the surface roughness of enamel after the application of different bleaching agents and to determine the effect of fluoride and bonding agent application on the roughness of bleached enamel. Materials and methods Forty-two dental slice polished enamel surfaces were randomly assigned to six groups. The surfaces of the slices were treated with 30% carbamide peroxide (CP) (groups I to III), or 38% hydrogen peroxide (HP) (groups IV to VI). Groups I and IV were only bleached. Topical fluoride was applied to the bleached surface of groups II and V. Groups III and VI were covered with a bonding agent. The surface roughness was analyzed with a profilometer. Data were subjected to analysis of one-way analysis of variance, Kruskal-Wallis, and Mann-Whitney U tests (p > 0.05). Results There were no statistically significant differences between the surface roughness of the untreated control specimens and the specimens treated with the bleaching materials, fluoride gel, and dental bonding agent (p > 0.05). Conclusion Bleaching treatment with 38% HP and 30% CP does not alter enamel surface roughness. Clinical significance The application of topical neutral sodium fluoride agents and dental bonding agents does not have any influence on enamel surface roughness.

Introduction: Tooth discolouration is the most common esthetic problems in dentistry. Direct composite veneer is an adjunctive therapy for severe teeth discolouration by attaching to the tooth surface using an acid etching and dental bonding agent. In several cases of severe discolouration, it is required to have certain preliminary treatments such as bleaching prior to the placement of the composite veneer. However, bleaching agents are able to lead the enamels morphology and microstructure alteration by inhibiting the polymerisation bonding thus affecting the veneer adhesion. This study was aimed to determine the tensile bond strength of direct composite veneers between the V and VII generation dentin bonding agent after extracoronal bleaching. Methods: This study was an experimental laboratory of as much as 32 human permanent maxillary central incisors were divided into 4 groups. Group 1 was treated with extracoronal bleaching and bonded with the V generation bonding nanohybrid composite. Group 2 was treated with extracoronal bleaching and bonded with the VIII generation bonding nanohybrid composite. Group 3 was only bonded with the V generation bonding nanohybrid composite. Group 4 was only bonded with the VIII generation bonding nanohybrid composite. All samples were immersed in artificial saliva then incubated at the room temperature for 24 hours. Results: The tensile strength value was determined using the Universal Testing Machine. The ANOVA test results showed significant differences in all four groups (p < 0.05). Conclusion: The VIII generation bonding agent had a higher tensile strength than the V generation.

ABSTRACT Aim To assess the influence of dentin substrate and chlorhexidine on the marginal seal of composite resin restorations. Materials and methods The sample comprised 20 third molars. Four cavities were drilled in the dentin surface, followed by sealing and restoration of sound dentin (n = 10) or carious dentin (n = 10). In the control group, cavities were immediately restored as follows: G1: one-bottle bonding agent (OB) + composite resin (CR); G2: chlorhexidine 2.0% (CLX) + OB + CR; G3: self-etch bonding agent (SE) + CR; G4: CLX + SE + CR. In the experimental group (carious dentin), carious lesions were induced with S. mutans and cavities were restored as in the control group. Five specimens from each group (sound and carious) were stored in brain–heart infusion (BHI) medium for 6 months. All specimens were submerged in methylene blue 0.5% to test for microleakage. The Kruskal-Wallis and Student- Newman-Keuls tests were used to assess results. Results On immediate assessment, there were no significant between-group differences in the sound dentin group, whereas in carious dentin, there was less leakage when OB and CLX were used. At 6 months, there was less leakage in the sound dentin group when OB and CLX were used; there were no between-group differences in carious dentin. Comparison of immediate and 6-month assessments showed a significant increase in leakage at 6 months when sound dentin was treated with SE and CLX and when carious dentin was treated with OB and CLX. Conclusion To ensure better dentin hybridization and preservation of the organic constituents of the dentin matrix, the properties of chlorhexidine digluconate and the components of the resin matrix must be taken into account. Clinical significance Metalloproteinases influence degradation of the hybrid layer in composite resin restorations, regardless of whether the bonding system used is one-bottle or self-etching.
