Calidad de adhesión en esmalte de dientes sometidos previamente a un aclaramiento dental.

Abstract

Introduction: Restorative dentistry in recent years has undergone constant evolution due to advances in adhesive technology, despite this it is a very delicate protocol and can be affected by different variables. The bleaching treatments generate oxygen free radicals, affecting the light curing processes affecting any adhesive protocol, without being definitive. They will have a period of about 14 days with a recovery of adhesive forces of 70% -80. Objectives: To determine if the quality of adhesion in enamel is compromised after a dental whitening. Materials and methods: A qualitative systematic review was carried out, which analyzed the effectiveness of adhesives after dental whitening. The works involved had inclusion criteria such as enamel adhesion, if they were with 4th generation, 5th generation and 6th generation adhesives, hydrogen peroxide, carbamide peroxide. Results and Discussion: A sample of 27 scientific articles was taken, of which a sample of 38 types of treatments was obtained which was subdivided into PC / PH, additionally it was subdivided into 4 control groups, immediate, 7 days,> 14 and adhesive values were compared. The quality of each generation of adhesive was compared, showing which group showed the greatest adherence. The loss of strength was observed when working immediately, changing significantly between the first to the second post-whitening. The PC and PH groups showed a difference in values within the same time since the treatment remained active longer in the PC group, this being the one that took the longest to reconstitute their adherence. Conclusion: There is a significant reduction in the bonding strength of enamel to restorative material after the application of carbamide peroxide or hydrogen peroxide, independent of the percentage of the reagent.
