Correct answer: E — Modified Widman flap (open flap debridement)

The modified Widman flap (Ramfjord and Nissle, 1974) is a mucoperiosteal flap elevated for the purpose of providing direct access for thorough root surface debridement (scaling and root planing) and removal of granulation tissue. It does not involve osseous recontouring (bone surgery). It aims to achieve a thin, closely adapted flap over the alveolar bone. Pocket reduction occurs primarily through long junctional epithelium formation rather than new attachment.
