A efetividade de sistemas adesivos universais e convencionais em esmalte fluorótico: revisão de literatura

Abstract

Dental fluorosis is a defect that occurs in dental enamel after chronically ingesting fluoridated solutions. When severely affected, intervention through restorative treatment is necessary. Thus, the adhesion of the substrate to the remnant is an important step for the procedure to be successful. Therefore, the effectiveness of universal and conventional adhesive systems in fluorotic enamel was analyzed, in order to obtain better choices in the conduct and comparison of products, to enable an effective and long-lasting therapy for dental elements with fluorosis. This research aims to carry out an overview of dental fluorosis, focusing on the action and performance of universal and conventional adhesive systems on teeth affected by fluorosis, in order to demonstrate its effectiveness and positive / negative points when submitted to restorative treatment, with based on a literature review, qualitative and exploratory. The study revealed that regardless of the use of primer or acid etching, adhesion in all techniques was more effective at the resin-enamel interface of healthy teeth. However, when comparing the best adhesion between the total conditioning (ER) and self- etching (SE) techniques, they obtained similar results after increasing the time of application in self-etching mode.
