“…However, reportedly, bonding strength higher than 10 MPa is considered clinically sufficient. 45,46 Therefore, the tensile bonding strength under the DFG laser irradiation, satisfied the clinical demand, is not thought to be a severe problem.…”

Selective removal of carious human dentin using a nanosecond pulsed laser operating at a wavelength of 5.85 µm Abstract. Less invasive methods for treating dental caries are strongly desired. However, conventional dental lasers do not always selectively remove caries or ensure good bonding to the composite resin. According to our previous study, demineralized dentin might be removed by a nanosecond pulsed laser operating at wavelengths of around 5.8 μm. The present study investigated the irradiation effect of the light on carious human dentin classified into "remove," "not remove," and "unclear" categories. Under 5.85-μm laser pulses, at average power densities of 30 W∕cm 2 and irradiation time of 2 s, the ablation depth of "remove" and "not remove," and also the ablation depth of "unclear" and "not remove," were significantly different (p < 0.01). The ablation depth was correlated with both Vickers hardness and Ca content. Thus, a nanosecond pulsed laser operating at 5.85 μm proved an effective less-invasive caries treatment.

“…Specimens without surface treatment became loose in storage in water after 90 days; however, silica coating after immersion in water increased its bond strength [23]. In tensile testing, it is also reported that tribochemical treatments provide durable bond strength [15], however, adhesive systems cannot provide clinically acceptable bond strength [24].…”

Objective: To evaluate the shear bond strength of a recent adhesive system used in the cementation of zirconia. Material and Methods: Overall, 72 zirconia specimens (Zirconzhan) were divided and randomized into 3 groups according to the type of surface treatment: G1 no treatment + adhesive system; G2 blasted with aluminum oxide + adhesive system and G3 tribochemical treatment (Rocatec Plus) + adhesive system. Half of each group (n = 12) had bond strength evaluated on two occasions: 24 hours after cementation, kept stored in distilled water at 37 ° C without thermal cycling, and after thermal cycling (5000 cycles, 5°C-55°C). Data were analyzed by ANOVA with Tukey's post-test (α≤0.05). Results: At first moment, G1 and G3 showed higher bond strength (8.64 ± 3.43 MPa and 6.55 ± 2.27 MPa) compared to G2, with no statistically significant difference between them. After thermal cycling, G3 showed higher bond strength (7.70 ± 1.82 MPa). Conclusion: Initially, only the adhesive system promoted higher bond strength, but after thermal cycling,bond strength decreased. The best treatment to promote high bond strength to zirconia is to associate tribochemical treatment with the adhesive system; most failures observed after thermal cycling were mixed and cohesive, showing a mechanical imbrication of the adhesive system, suggesting that there is no chemical bond; and the surface of the group with greater bond strength after thermal cycling showed more surface irregularities compared to the other groups.

“…Phosphate ester monomercontaining adhesion promoters with polar functional groups such as 10-methacryloyloxydecyl dihydrogenphosphate (10-MDP) [12,43,44] could make covalent bonds with the hydroxyl groups on the zirconia surface. Currently, alumina or silica coating followed by the application of MDP containing silane coupling agent and MDP-based resin cement appears to be more resistant to aging [12,45] compared to methacrylate based conventional resin luting cements [12,25,33,46].…”

Yttrium-stabilized zirconium dioxide, a commonly used material in conjunction with CAD/CAM technologies in dentistry, is an oxide ceramic that does not comprise silicon dioxide (SiO 2 ) phase in its microstructure. Since it is challenging to create durable adhesion between resin cements and this kind of nonetchable ceramic, efforts have been made to develop innovative surface conditioning methods over the years.While some chemical methods based on using adhesion promoters only did not perform stable adhesion, others utilizing physico-chemical conditioning methods provided better adhesion where the latter is also being questioned on impairing mechanical stability of zirconium dioxide (ZrO 2 ) due to t→m phase transformation.This review will highlight current surface conditioning concepts to achieve best adhesion to zirconium dioxide, challenges related to conditioning methods or resin-based luting cements, and contemplate on future prospects.
