Clinical Evaluation of Self-adhesive Bulk-fill Resin Composite vs Conventionally-bonded Bulk-fill Resin Composite in Restoration of Proximal Lesions: An 18 Months Follow-up

So, Surefil one was presented by the manufacturer as an innovative self-adhesive restorative substance with silver amalgam-like characteristics and composite-material esthetics. 8The initiator system, according to the manufacturer, combines the photoinitiator camphor quinone and a persulfate with two reducing agents utilized in both the self and light-curing procedures.This results in both surface light curing and bulk curing (in the dark). 9In addition, the novel self -adhesive Bulk-fill composite hybrid contains a radically polymerizable modified polyacid system (MOPOS), which increases strength through copolymerization IntroductIonComposite resins have already been used in dentistry for approximately 50 years, and the gaps in clinical practice they caused were a major factor in their development. 1The first 2 decades were devoted to the creation of composite resins with enhanced mechanical and polishing properties.Then, the emphasis switched to the creation of resins with less polymerization shrinkage in order to reduce postoperative sensitivity, cusp deflection, and the emergence of gaps and to increase the longevity of these materials. 2ulk-fill composite resins have been in use for >10 years.The manufacturers of Bulk-fill composite resins claim it to be a restorative material that may be used in increments of up to 4 mm without compromising its properties. 3Although high-viscosity bulk fill is simpler to handle than regular alternatives, they require a separate adhesive system before being employed.In this context, the further reduction of treatment phases with regard to selfadhesiveness is an interesting aspect. 4he creation of self-adhesive composites, which got away with the need for an adhesive and cut down on the amount of time that blood or saliva contamination may jeopardize the restoration, was still another step towards simplification 5 ; however, a number of lab studies have raised concerns about whether these materials are a viable substitute for composites that use a separate adhesive.
