Representative debonding surface of each group. CI: Representative debonding surface of group CI, in which there is less adhesive left on the dentin surface and some resin tags have broken away from the dentinal tubule; S8I: Representative debonding surface of group S8I, almost all the dentinal tubule is still filled with resin; S6I: Representative debonding surface of group S6I; not only the resin tags but also resin can be obtained on the debonding dentin surface. S4I: Representative debonding surface of group S4I, which shows a similar result as S6I.
