We provide a new exact solution of the Einstein equations which generalizes the noncommutative geometry inspired Schwarzschild metric, we previously obtained. We consider here more general relations between the energy density and the radial pressure and find new a geometry describing a regular ``dirty black hole''. We discuss strong and weak energy condition violations and various aspects of the regular dirty black hole thermodynamics.

Using the Nakas-Kanti top-down approach, the author embeds the Morris-Thorne and Molina-Neves wormholes in a regular five-dimensional anti-de Sitter bulk, so the wormhole on the brane is supported entirely by bulk fields.
