Effect of various intracanal medicaments on the bond strength of self-adhesive resin cement to root canal dentin

Figures & data

Figure 1. Representative images for the failures. (A) Adhesive failure (between the cement and root dentin), (B) cohesive fracture (within the dentin, cement layer or post) and (C) mixed (a combination of cohesive and adhesive).

Table 1. Mean bond strength ± SD and failure modes of the experimental groups.

		Failure modes (%)
Group	Bond strength ± SD	Adhesive	Cohesive	Mixed
Control	6.82 ± 3.00a	58.3	33.3	8.3
Calcium hydroxide	5.22 ± 2.78ab	62.5	16.7	28.8
DAP	5.73 ± 2.45ab	45.8	28.8	33.3
TAP	4.25 ± 2.09b	58.3	16.7	25
