Guided tissue regeneration is regeneration of what three things?

  1. Bone, Cementum, PDL

  2. Bone, Enamel, Dentin

  3. Dentin, Gingiva, Cementum

  4. PDL, Gingiva, Enamel

The correct answer is: Bone, Cementum, PDL

Guided tissue regeneration involves regenerating bone, cementum, and the periodontal ligament (PDL). A is the correct answer because it includes all three components. B, C, and D are incorrect because they each only include two of the three components. Enamel is not a part of guided tissue regeneration, as it is the hard outer layer of the tooth. Gingiva is also not included as it is the soft tissue surrounding the tooth, not a part of the actual regeneration process.
