【单选题】From the abstract, what is the result of this article?
A.
Overall 10 publications with clinical trials could be identified. Their clinical outcome was compared with that laboratory bond strength studies.
B.
Clinical data provide strong evidence that air-abrasion at a moderate pressure in combination with using phosphate monomer containing primers and/or luting resins provide long-term durable bonding to glass-infiltrated alumina and zirconia ceramic under the humid and stressful oral conditions.
C.
As simple and clinically reliable bonding methods to oxide ceramics exist, the rationale for development of alternative bonding methods might be reconsidered especially when these methods are more time consuming or require rather complicated and/or technique sensitive procedures.
D.
Conducting a PubMed database search in May 2014 for articles dealing with the resin bond to dental zirconia ceramic reveals an astonishing increase of research being published in the last two decades years.
