This case report demonstrated a challenging clinical case addressed within a multidisciplinary approach to achieve its maintenance, even though had a poor prognosis. It was associated with the endodontic treatment with mucogingival techniques, including periodontal microsurgery and connective tissue graft.
A patient presented a deep gingival recession with the apex-exposed non-vital tooth with interproximal bone loss (RT2) and without mobility. The treatment involved an initial endodontic approach and periodontal therapy (scaling and root planing), microsurgical techniques with coronally advanced flap (CAF), root preparation with PrefGel® (24% EDTA), enamel matrix derivatives (Emdogain®), and connective tissue graft. As a clinical result, it was verified an increase of keratinized tissue width and gingival thickness, and root coverage, reaching good esthetics and a stable result after 17 months.
The correct diagnosis and technique selection may affect directly the outcome, especially in challenging cases. Even though there was a poor prognosis, an adequate treatment plan, patient cooperation, and technique mastery help to achieve a high level of root coverage, esthetic recovering, and successful outcome.
