The configuration factor (C-factors) is an important clinical parameter and is related to polymerization shrinkage, bond strength, and durability. High C-factors indicate situations in which the material polymerizes under greater external constraint.<\/jats:p>\n <\/jats:sec>\n \n Aim:<\/jats:title>\n To evaluate the effect of C-factor on the bond strength of universal dental adhesives to the dentin of the cavity floor and cavity wall in class-I composite restorations using nanohybrid composites.<\/jats:p>\n <\/jats:sec>\n \n Materials and Methods:<\/jats:title>\n \n Sixty noncarious human molars were randomly divided into four groups (\n n<\/jats:italic>\n = 15). Then, each group was subdivided into two subgroups according to the type of adhesive used: Prime and Bond Universal (Dentsply) or Adper Single Bond 2 (3M). After the bonding procedure, nanohybrid composite was applied in 2 mm increments to fill the cavities. The teeth were sectioned into 2 mm\n 2<\/jats:sup>\n sticks and micro-tensile bond strength (\u03bcTBS) was measured at two areas: cavity wall and cavity floor using a universal testing machine. Fracture pattern was analyzed using the stereomicroscope. Results were tabulated and statistical analysis was done using the Analysis of Variance with\n post hoc<\/jats:italic>\n Tukey\u2019s test.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Prime and Bond Universal had significantly better \u03bcTBS (mean = 8.53) as compared to Adper Single Bond 2 at the floor (mean = 6.64) of the cavity. At the wall of the cavity, Prime and Bond Universal was better, but the difference was not statistically significant (\n P<\/jats:italic>\n < 0.05). The cohesive mode of fracture was common in all the groups.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n To overcome high C-factor in Class I cavities, Prime and Bond universal had better bond strength when measured at the floor and wall of the cavity.<\/jats:p>\n <\/jats:sec>","DOI":"10.4103\/jcde.jcde_247_25","type":"journal-article","created":{"date-parts":[[2025,6,2]],"date-time":"2025-06-02T02:00:44Z","timestamp":1748829644000},"page":"559-564","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Role of configuration factor on bond strength of universal adhesives in occlusal cavities: An in vitro study"],"prefix":"10.4103","volume":"28","author":[{"given":"Pushpal","family":"Ingle","sequence":"first","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, Dr. D.
