Dependent Origination in terms of conventional truth or teaching (Vohara Desana) and Ultimate truth or teaching (Paramattha Desana)?
The Buddha did not teach Dependent Origination has a "conventional truth". Dependent Origination, as taught by the Buddha, only explains the arising of the ideas of "beings" ("satta") which cause the arising of suffering. 


  In the course of the future there will be monks who
  won't listen when discourses that are words of the Tathagata — deep,
  deep in their meaning, transcendent, connected with emptiness — are
  being recited. They won't lend ear, won't set their hearts on knowing
  them, won't regard these teachings as worth grasping or mastering. But
  they will listen when discourses that are literary works — the works
  of poets, elegant in sound, elegant in rhetoric, the work of
  outsiders, words of disciples — are recited. They will lend ear and
  set their hearts on knowing them. They will regard these teachings as
  worth grasping &amp; mastering. In this way the disappearance of the
  discourses that are words of the Tathagata — deep, deep in their
  meaning, transcendent, connected with emptiness — will come about.
