Resumen
[Español] La presente investigación in vitro se basa en el efecto del hipoclorito de sodio al 5.25% Vs el adhesivo autocondicionante ortodóncico para aumentar la resistencia al desalojo de brackets metálicos nuevos y reacondicionados y recementados. Se tomaron 50 premolares humanos recién extraídos y luego fueron preparadas sus respectivas superficies para ser sometidas a tres técnicas adhesivas distintas. Se dividieron los grupos en: Grupo I (control): Brackets nuevos y recementado acondicionando el esmalte con grabado ácido fosfórico al 37% de Prime-Dent, adhesivo Ortho Solo (Ormco) y resina Transbondtm xt (3M). Grupo II: Brackets nuevos y recementados acondicionando el esmalte con hipoclorito de sodio al 5.25%, grabado ácido 37%, adhesivo Ortho Solo (Ormco) y resina Transbondtm xt (3M). Grupo III: Brackets nuevos, reacondicionados y recementados acondicionando el esmalte con adhesivo autocondicionante Transbond plus self etching primer (3M) y resina Transbondtm xt (3M). Posteriormente, se colocaron en la Universal Testing Machine MTI-2K, determinándose que el hipoclorito de sodio al 5.25% previo a la aplicación del grabado ácido al 37% con el uso de adhesivo autocondicionante aumenta la adhesión al esmalte.
[English] The present in vitro investigation is based on the effect of 5.25% sodium hypochlorite Vs orthodontic self-conditioning adhesive to increase the resistance to dislodgement of new and reconditioned and recemented metal brackets. 50 recently extracted human premolars were taken and then their respective dental surfaces were prepared and subjected to three different adhesive techniques. Groups were divided into: Group I (control): New and recemented brackets, conditioning the enamel with 37% acid etching, 37% Prime-Dent phosphoric acid, Ortho Solo adhesive (Ormco) and Transbond tmxt resin (3M). Group II: New and recemented brackets conditioning the enamel with 5.25% sodium hypochlorite, 37% acid etching, Ortho Solo (Ormco) adhesive and Transbond tmxt (3M) resin. Group III: New and recemented brackets conditioning the enamel only with Transbond self-conditioning adhesive plus self-etching primer (3M) and Transbond tmxt resin (3M). Subsequently, they were placed in the Universal Testing Machine MTI2K, determining that the 5.25% sodium hypochlorite prior to the application of the 37% acid etching with the use of self-conditioning adhesive increases adhesion to enamel.
