Abstract: Objective: Gingival recession often results in root sensitivity, plaque retention, and esthetic issues, which have an impact on patients’oral health and facial appearance. In this case, root coverage was used to treat gingival recession and reduce root sensitivity. Diagnosis and treatment: The coronally advanced flap in combination with a connective tissue graft was used to treat the (recession type,RT) 1 recession. Results: Two weeks after the operation, the gingival margin of the recipient area was slightly swollen. After 12 months of follow-up, the gingival margin position tended to be stable, the root coverage rate reached 100%, and the width and clinical attachment of keratinized gingival increased. The patient had no uncomfortable symptoms such as root sensitivity, frenulum traction and scarring. The aesthetic effect of gingival is good. Conclusions: Coronally advanced flap combined with connective tissue graft is effective in treating the RT 1 recession, which not only obtains complete root coverage with good aesthetic effect, but also increases the width of the keratinized gingiva and clinical attachment in the operation area.
