Fenestration gingival defect in erupting permanent mandibular incisors: A case report

Bilateral fenestration of the labial gingival tissue of the permanent mandibular central incisors is described. The situation was followed over a 2-year period with no treatment other than prophylaxis and oral hygiene instruction. The final outcome was an apical positioning of the gingival margin, which was lower than that of the adjacent uninvolved teeth.
