Indirect restoration in composite resin: a clinical report of self-adhesive cementation in deproteinized dentin

Abstract

A 17-year-old female patient, melanoderma, sought the Center for Reception and Emergency Care at the Dental School of the Federal University of Pernambuco (Recife, Brazil). The main complaint was restricted to the need for rehabilitation of a posterior tooth submitted to recent endodontic treatment. The anamnesis indicated absence of painful symptomatology associated to the tooth in question. After physical and radiographic examinations, there was a coronary structural loss of more than 50%, with healthy or adequately restored teeth, as well as absence of radiolucent images suggestive of periapical lesion (Figure 1). The treatment plan indicated an indirect restoration in composite resin using self-adhesive cement for fixation, associated with the technique of dentin deproteinization. The need to use an intracanal fiber glass post was also observed.Initially, under relative isolation, the temporary restorative material and remaining carious tissue were removed with spherical diamond tips (KG Sorensen) (Figure 2A).
