This study evaluated the impact of different surface treatments – cold atmospheric plasma (CAP), airborne particle abrasion (APA), hydrofluoric acid (HF), and their combinations – on the bond strength of two zirconia types (3Y-TZP, 5YSZ) to dentin using self-adhesive resin cement, with or without primer. Two hundred zirconia and dentin specimens underwent surface treatment, cementation, thermocyclic aging, and shear bond strength (SBS) testing. Results showed APA and CAP significantly enhanced SBS (P < 0.001), while HF had no effect. Combined treatments (APA+CAP, CAP+HF) slightly reduced SBS. Primer application improved SBS across all groups. APA or CAP with a 10-MDP primer achieved the highest SBS values. CAP is a viable alternative to APA, though APA remains cost effective. HF is not recommended for surface treatment of zirconia. CAP exhibited a slightly higher, yet statistically comparable, SBS between zirconia and dentin when compared with APA. Nonetheless, APA may still represent the simplest and most cost-effective technique available to date. The combination of APA and CAP might not be recommended, as it showed a slight reduction in SBS of the tested specimens and inefficiency in terms of time and energy. Hydrofluoric acid showed no impact on SBS when combined with CAP. Both 3Y-TZP and 5YSZ can provide adequate clinical bond strength with the proper surface treatment and adhesive protocol.
