Figure 2. Relationships between least-squares means of microtensile bond strengths and Hoys solubility parameters for polar forces (
p) of resins 15 (numbers in parentheses indicate the N upon which the mean value is based). (A) Least-squares means bond strengths of 50% ethanol-solvated resins 15 to acid-etched dentin saturated with water. (B) Least-squares means bond strengths of 50% ethanol-solvated resins 15 to acid-etched dentin saturated with ethanol. (C) Least-squares means bond strengths of 50% ethanol-solvated resins 15 to dry acid-etched dentin.
