It is a wonder that no one has mentioned prajnaparamita yet. Also truth could be understood as satya, thus we have catvari arya satyani (4NT) and satyadvaya (two truths). But I'd say, unlike in the European tradition, Buddhism works with the personal, rather than the objective aspect, so wisdom instead of truth. ("And ye shall know the truth, and the truth shall make you free.", "I am the way, the truth, and the life")
The Buddhist concept of truth is not an objective, independent thing or knowledge but something to be realised and has relevance only as far as its realisation happens. On the other hand, the truth in the European view is something outside of us, therefore knowable by all and doesn't require any inner achievement. Or, from a Christian perspective, truth is by grace and something people has to believe in.
Another perspective is truth as correct view. It is the beginning of the path in Buddhism to obtain a correct understanding of the teaching and then eventually realise it. In the European tradition truth is something one attains in the end and completes one's journey (holy grail, scientific truth). Also note that Socrates was a philosopher and not a sage.
A similar phenomenon in Buddhism like the European understanding of truth is the teaching of buddha-nature. Because the full knowledge of buddha-nature is buddhahood, also everyone has it and can realise it. But again, buddha-nature is a personal thing and not an independent one.
"While teachers of the middle way, mind only, transcendent wisdom, mantra, and other schools may have their own assertions, the fulfillment of those intentions is the same. There is not a single thing that is not contained within mind."
(Gampopa to Düsum Khyenpa, in "The First Karmapa", KTD Pub, p254)
“If you recognize the world of appearance and existence as the mind, realize the mind itself as empty, and have no grasping at the superiority of your realizations — this is the ultimate view."
(Chegom Dzongpa, in "The Book of Kadam", Wisdom Pub, p609)
