What kind of graft aims to cover root surfaces?

  1. Free gingival graft

  2. Connective tissue graft

  3. Pedicle graft

  4. Guided tissue regeneration

The correct answer is: Connective tissue graft

A connective tissue graft aims to cover root surfaces by utilizing tissue from the patient's palate or another donor source to augment the gum tissue around the teeth. This type of graft is specifically designed to increase the amount of gum tissue, ultimately covering exposed roots and helping to prevent further recession. The other options are incorrect: A. Free gingival grafts are used to increase the amount of attached gingiva and are not specifically focused on covering root surfaces. C. Pedicle grafts involve using nearby tissue to cover specific areas of recession but are different from connective tissue grafts. D. Guided tissue regeneration is a technique used to regenerate bone and periodontal ligament attachment and is not directly related to covering root surfaces.
