Typical SEM images showing adhesive coating layers on tooth root dentine. TPH is a composite (Dentsply), used to facilitate the cutting of cross-sections and avoid adhesive coating layer chipping/fracture during the cutting process. The mean value of adhesive coating thickness for each adhesive is plotted in (E) (mean ± sd; n = 6). Dissimilar letters indicate values that are significantly different from each other (p < 0.05).
