“…EDTA is water soluble; hence, it might be rinsed off the EDTA-treated dentin. This might not be able to sustain MMP inhibition for long durations such as the 6-month period implemented in this study [8].…”

“…Hence, long-term effectiveness of CHX would be explained by its high substantivity, regardless of its concentration. After oversaturating proteases' binding sites, it can remain bound to collagen fibrils for a later release if still available in higher concentrations [8].…”

“…CHX acts by cation chelation, sequestrating calcium and zinc ions essential for the activation of the MMPs and inhibiting collagenase and gelatinase activity of dentin matrix [8]. Recent in vivo and in vitro studies have demonstrated that application of chlorhexidine has broad-spectrum MMP-inhibitory effects and significantly improves the integrity of the hybrid layer created by a simplified etch-and-rinse adhesive [4].…”

Tell: +98-9171016736Effect of pretreatment with different MMP inhibitors on shear bond strength of composite to primary teeth dentin after six months of aging Abstract Background: loss of hybrid layer integrity compromises the resin-dentin bond stability. Subsequent release and activation of matrix metalloproteinase enzymes during dental restorative procedures or caries development are contributing factors to dentin-adhesive bond failure. Aim:To investigate the effect of pre-treatment with different MMP inhibitors on the shear bond strength (SBS) of an etch-and-rinse adhesive (Adper Single Bond 2) to primary teeth dentin after six months of aging.Methods: Sixty extracted anterior primary teeth ,due to orthodontic reasons ,were selected. A dentin block (6.0 mm × 6.0 mm × 2.0 mm) was obtained from each tooth. All the dentin blocks (n = 60) were pretreated for 60 s with either 0.01 M phosphate buffered saline (PBS, pH 7.2) in the control group, 2% : Chlorhexidine (CHX) solution, 2% Doxycycline (DO)solution and EDTA 17% after etching and before applying etch-and-rinse adhesive system (Adper Single Bond 2). Then composite was applied in clear teflon cylinders . The specimens were stored in artificial saliva for 6 months at 37ºC and then the SBS values were determined with a universal testing machine .Representative samples were selected for visualization of the failure mode under stereomicroscope and SEM.Results: No statistically significant difference observed between the SBS of the EDTA group, DO group and the control group (P value>0.05). CHX showed significantly higher SBS values compared to the other groups of the study after six months(P value=0.011). Conclusion:Chlorhexidine significantly preserved the SBS of composite resin to deciduous dentin using etch and rinse adhesive Adper Single Bond 2 after 6 months of aging in artificial saliva.

Objetivos: O condicionamento da superfície dos tecidos dentários duros com ácido fosfórico 35% é normalmente utilizado para fornecer retenção micromecânica para adesivos odontológicos. Quando lavado da superfície, o ácido pode gerar gosto amargo e desagradável ao paladar do paciente. O objetivo deste estudo foi analisar o efeito da adição de um agente aromatizante à composição do gel de ácido fosfórico 35% e investigar se existe alteração de características fundamentais deste material, como sua capacidade de desmineralizar a superfície dentária. Métodos: Além de um grupo controle (sem flavorizante), foram testados grupos de ácido fosfórico 35% com a adição de 0,5% ou 3% do aromatizante (Aroma Abacaxi Pó; Bio Green Ingredients). Foram realizadas análises de viscosidade, estabilidade do pH e de desmineralização da superfície de esmalte condicionada por microscopia eletrônica de varredura, além de teste de resistência de união ao esmalte por microcisalhamento. Resultados: Apesar dos grupos apresentarem pequenas diferenças entre si, nenhuma das alterações se mostrou significativa, exceto o aumento da viscosidade do gel contendo 3% do aromatizante. Conclusões: A adição de agente aromatizante ao gel condicionador de ácido fosfórico 35% parece ser alternativa viável para reduzir os problemas relacionados ao contato com o sabor desagradável do material, uma vez que não promoveu alteração negativa significativa nas características e comportamento do ácido.

“…4 Furthermore, composites are not cariostatic materials, and bonding to dentin can be unpredictable with a significant variation in the bonding efficiency. [5][6][7] Research is still ongoing to find an ideal material for restoration, which has physical and mechanical properties similar to tooth structure and resistant to masticatory forces, while having satisfactory esthetic properties. 8 Glass ionomer has been extensively explored due to several benefits they provide compared with other restorative materials.…”
