WebSummary – What is C-Factor? C-Factor (Configuration Factor) is the ratio of bonded to unbonded surfaces in a cavity. Higher C-Factors result in higher stresses. The … Webrandomly assigned into two main groups: a high c-factor group with Class I cavities, and a low c-factor group with flat tened dentin surfaces. For high c-factor groups, standardized Class I occlu sal preparations (length: 5 mm; width 4 mm; depth 3 mm; ± 0.01 mm) were made in each tooth using BR-41 and SF
