Gingival fenestration (GF) is a distinct clinical entity of uncertain etiology that is seldom documented in the literature. It has been associated mainly with submucosal mechanical irritants such as calculus that subsequently create an opening in the oral soft tissue, usually at facial anterior sites. Surgical correction may be indicated to address functional and/or esthetic concerns.
The patient, a 74-year-old male, presented to the clinic with a chief complaint of "something is poking through my gum." Clinical exam revealed a gingival fenestration on the facial of tooth #11, associated with what appeared to be a pronounced noncarious cervical lesion (NCCL). Surgical treatment consisted of a connective tissue graft and odontoplasty of the sharp protruding edge of the root surface. Healing was uneventful with excellent closure of the fenestration and no evidence of recurrence after 18 months of follow-up.
GF is a perforation of the mucosa typically associated with underlying sharp mechanical etiology. This report describes a fenestration that developed from a probable abfractive lesion, which later was successfully closed and exhibits long-term stability.
牙龈开窗（GF）是一种病因不明的独特临床病症，在文献中鲜有记载。它主要与诸如牙结石等黏膜下机械刺激物有关，这些刺激物随后会在口腔软组织中形成一个开口，通常位于面部前部位置。可能需要进行手术矫正以解决功能和/或美观问题。
患者为一名74岁男性，因“牙龈有东西穿出”为主诉前来就诊。临床检查发现11号牙面部有牙龈开窗，伴有一个明显的非龋性颈部病变（NCCL）。手术治疗包括结缔组织移植和对根面尖锐突出边缘进行牙体成形术。愈合过程顺利，开窗处完美闭合，随访18个月后无复发迹象。
牙龈开窗是一种通常与潜在尖锐机械病因相关的黏膜穿孔。本报告描述了一例由可能的磨损性病变发展而来的开窗病例，该病例后来成功闭合并具有长期稳定性。
