Aim: The current clinical investigation aimed to compare and contrast the clinical efficacy of self- adhesive bulk fill resin composite and traditionally bonded bulk fill resin composite in the restoration of proximal lesions during the course of 18 months.
Methodology: In a parallel study design, forty participants with carious proximal lesions were assigned at random to the intervention (Surefil-one) and comparison (bulk-fill) groups. All ingredients were used in accordance with the directions provided by the manufacturer. Two blinded assessors evaluated restorations at initial screening (one week), six months, twelve months, and 18 months using modified USPHS criteria measuring (marginal adaption, marginal discoloration, surface roughness, anatomic form, postoperative sensitivity, recurrent caries, and retention analysis).

Results: Intergroup comparisons of both materials revealed no differences of statistical significance in marginal adaptation (P = 0.0952), recurrent caries (P = 0.8728), postoperative sensitivity (P = 0.5936), or retention analysis (P = 0.3173). whereas there was a difference of statistical significance between both materials for marginal discoloration after 18 months (P = 0.0235), surface roughness after 12 and 18 months (P = 0.0013 and P = 0.0001 respectively), and anatomic form after 18 months (P = 0.0023).
Conclusions: Over an 18-month test time frame, self-adhesive bulk-fill resin composite hybrid (surefil-one) revealed clinically less satisfying performance when compared to traditionally bonded bulk-fill resin composite.
