This clinical investigation examined the effectiveness of a recently created resin composite for back teeth, which is universal supra-nano spherical filled, using revised United States Public Health Service (USPHS) standards.<\/jats:p>\n <\/jats:sec>\n \n Aims:<\/jats:title>\n In order to conduct a clinical evaluation and comparison of two resin composites \u2013 Omnichroma, a universal supra-nano spherical filled resin composite, and Harmonize, a universal nanohybrid composite resin in Class I posterior restorations over the course of 6 months.<\/jats:p>\n <\/jats:sec>\n \n Materials and Methods:<\/jats:title>\n \n A randomized, double-blind, split-mouth clinical trial was conducted in 50 patients, each requiring two Class I occlusal restorations. In each patient, one cavity was restored with a universal supra-nano spherical composite resin (Omnichroma,\n n<\/jats:italic>\n = 50) and the other with a universal nanohybrid composite resin (Harmonize,\n n<\/jats:italic>\n = 50). A self-etch, light-cured adhesive (Bond Force) was used for all restorations. Using modified USPHS criteria for retention, color match, marginal adaptation, surface texture, anatomic form (wear), postoperative sensitivity, and secondary caries, two calibrated evaluators, who were blinded to the materials, evaluated the restorations at 1 week (baseline), 1 month, 3 months, and 6 months. Use of Fisher\u2019s exact test (\u03b1 = 0.05) was used for the analysis of categorical data.\n <\/jats:p>\n <\/jats:sec>\n \n Statistical Analysis Used:<\/jats:title>\n Frequencies and percentages were calculated, and Fisher\u2019s exact test was used for intergroup comparisons at each recall interval.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n A 100% recall at 1 week, 1 month, 3 months, and 6 months was achieved since all 50 patients were present at every recall session. When it came to clinical performance, both Omnichroma and Harmonize were on par. values of Bravo (clinically acceptable) and Alpha (excellent) were given to the majority of restorations, while no Charlie (failure) values were recorded. For each memory metric, there were no statistically significant differences between the two materials (\n P<\/jats:italic>\n > 0.05).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n Within the 6-month follow-up period, Omnichroma and Harmonize composite resins demonstrated comparable and clinically acceptable performance in Class I posterior restorations.<\/jats:p>\n
