Effect of Root Dentin Pretreatment on Micro-Push-Out Bond Strength of Fiber Posts to Root Canal Dentin: Cold Atmospheric Argon Plasma (CAAP) and Ethylenediaminetetraacetic Acid (EDTA)

Table 1

Frequency distribution of the modes of failure in different parts of the root.

Failure mode	AD^1	AP^2	CD^3	CP^4	M1^5	M2^6
Apical third	6	13	11	2	4	4
Middle third	1	8	11	8	8	4
Coronal third	0	6	12	12	6	4

¹Adhesive failure between dentin and cement (no cement remaining on the post). ²Adhesive failure between cement and post (post is entirely covered with resin cement). ³Cohesive failure in dentin. ⁴Cohesive failure in the post. ⁵Mixed failure such that 0% to 50% of the post surface was covered with cement. ⁶Mixed failure such that 50% to 100% of the post surface was covered with cement.
