Beyond the Norm: A Unique Case Report of Traumatic Fibroma Excision and Management of Mucosal Fenestration

Mucosal fenestration is a clinical condition in which the surrounding mucosa (or gingiva) is compromised, exposing the root of the tooth to the surrounding oral cavity. This condition is most commonly observed in the anterior region of the dentition due to a thin labial cortex. “Traumatic fibroma” is a common benign exophytic lesion that develops in the oral cavity as a result of tissue injury, often referred to as an irritation fibroma. The lower labial mucosa, buccal mucosa, and tongue are the most frequently affected areas. A 52-year-old female presented with a traumatic fibroma and a mucosal fenestration defect in the lower front tooth region. The lesion had progressively enlarged over the course of one year, necessitating a multidisciplinary therapeutic approach. The root apex was exposed through the defect and exhibited a distinctly darker colouration, resembling that of a non-vital tooth. A comprehensive treatment strategy was designed, consisting of endodontic therapy, fibroma excision, root resection, regenerative periodontal surgery with bone grafts, and Guided Tissue Regeneration (GTR) to correct the mucosal fenestration. A three-month follow-up revealed satisfactory healing and closure of the defect.
