AbstractIntroductionGingival fenestration (GF) is scarcely reported in the literature. We present a unique case of GF defect combined with gingivitis and altered passive eruption (APE).Case PresentationAn 18‐year‐old female patient with gingivitis, APE, and GF in the mandibular left central incisor presented for periodontal treatment. The gingival lesion was successfully treated with basic periodontal therapy gingivectomy, and gingivoplasty and resulted in an excellent aesthetic long‐term outcome. This case report shows its 8‐year clinical follow‐up.ConclusionThere are no earlier reports dealing with the use of gingivoplasty for the treatment of GF, as it is not the usual therapeutic intervention for these defects. Gingivoplasty proved to be effective in treating GF.Why is this case new information? Available literature on gingival fenestration defects does not describe gingivectomy and gingivoplasty as a treatment of choice. Gingivectomy and gingivoplasty proved to be effective in treating gingival fenestration defects. What are the keys to successful management of this case? Proper diagnosis. What are the primary limitations to success in this case? Gingival fenestration has been defined when the overlying gingiva is denuded, exposing the root to the oral cavity. However, in this case report, only the crown was exposed because the patient had altered passive eruption.
