Effect of Snow-plow Technique on the Postoperative Pain Following Direct Composite Restoration

The snow-plow technique involves placing a thin layer of uncured flowable bulk-fill resin on the gingival floor of a Class II cavity, immediately followed by placement of a packable bulk-fill composite. Both materials are light-cured simultaneously, allowing the flowable resin to fill voids and improve marginal adaptation.

The resin coating technique involves applying and light-curing a thin layer of flowable bulk-fill resin after adhesive application to create a stress-absorbing layer on dentin (resin coating), followed by restoration with packable bulk-fill composite. This approach aims to protect the dentin, enhance bond stability, and reduce postoperative sensitivity
