Gingival Recession in Primary Maxillary Incisors due to Fingernail Scratching: A Rare Case Report.

Self-inflicted gingival injuries typically occur in patients with psychological disorders and rarely in normal individuals. This article is aimed at reporting an unusual case of gingival recession caused by a fingernail-scratching habit. A 5-year-old female patient presented to the Pediatric Dentistry Department at the Ibn Sina Center for Consultation and Dental Treatment in Rabat, Morocco, with complaints of gingival recession localized in her four maxillary primary incisors. After a detailed medical and personal history and clinical examination, the diagnosis of self-inflicted gingival injury was established. The treatment plan included oral hygiene instructions, the application of analgesic and antiseptic gel, and behavioral management. Regular follow-ups over a period of 16 months were crucial for monitoring the patient's progress, which eventually led to the cessation of the habit with no recurrence. Self-inflicted oral injuries in pediatric patients pose diagnostic challenges. The development of such habits in psychologically normal children is difficult to explain, suggesting the need for a comprehensive approach. Managing self-inflicted injuries is complex and requires a personalized strategy that may include psychotherapy, family support, and regular monitoring. This case highlights the importance of taking a comprehensive history and adopting a multidisciplinary approach to diagnose and manage self-inflicted gingival injury, achieving positive outcomes.
