Abstract
This study was conducted to assess the clinical performance of injection-molded bulk fill
composite and incrementally packed conventional composite, considering their respective cavity
designs and curing techniques, in moderate-sized proximal cavities of permanent molars.
Patients were randomly divided into two equal groups where each patient received
either a conventionally packed proximal restoration or an injected molded one. After pre-operative
assessment and operative field preparation, cavities of the injection-molding group were finished
to the recommended internal trumpet-shape outline and beveled circumferentially to infinity
keeping all margins in enamel. Cavities of the conventional group, on the other hand, were saucer
shaped with no circumferential beveling. Beveled cavities received injection molded restoration
of pre-heated bulk-fill composite; while non-beveled cavities were filled incrementally with a
conventional composite. Restorations were finished and polished, and patients were scheduled for
follow-up assessment appointments at 48 hours, one week (T0), 3 months (T1), 6 months (T2), 9
months (T3), and 12 months (T4).
