Which flap is specifically designed to provide access to subgingival areas for debridement?
Coronally positioned flap
Apically positioned flap
Modified Widman flap
Free gingival graft
The correct answer is: Modified Widman flap
The correct answer is the Modified Widman flap (Choice C). This flap is specifically designed to provide access to subgingival areas for debridement. The Modified Widman flap involves reflection of a full-thickness flap, debridement of the root surfaces, and reattachment of the flap at a level more apical than its original position to eliminate the pocket and establish a new biological width. This technique allows for thorough cleaning of subgingival areas and promotes better healing outcomes for the patient. Choices A, B, and D are incorrect: - The Coronally positioned flap (Choice A) involves moving the gingival margin coronally to correct shallow pockets and is not specifically designed to provide access to subgingival areas for debridement. - The Apically positioned flap (Choice B) involves moving the gingival margin apically to cover exposed root surfaces and is not specifically designed to provide access to subgingival areas for debridement. - The Free gingival graft (Choice D) is a procedure where tissue is taken from the palate or another donor site and placed in an area where there is inadequate attached gingiva, but it is not specifically designed to provide access to subgingival areas for debridement.
