PDF: Necrotizing Ulcerative Gingivitis (NUG): Clinical Case, Risk Factors and Step-by-Step Treatment



This clinical case report presents the diagnosis and management of Necrotizing Ulcerative Gingivitis (NUG) in a 21-year-old female with no systemic conditions but exposed to significant emotional stress—an important predisposing factor in the development of NUG.

The patient showed classic signs of the disease: intense gingival pain, spontaneous bleeding, halitosis, and "punched-out" interdental papillae.


Clinical and radiographic evaluations ruled out systemic pathology and bone loss.

The treatment was carried out in three phases:

1. Initial debridement and infection control with ultrasonic cleaning, chlorhexidine rinses, and metronidazole.

2. Subgingival instrumentation once acute symptoms subsided.

3. Oral hygiene reinforcement to prevent recurrence.


The patient showed complete resolution of lesions and restoration of periodontal health within weeks.

The report highlights the importance of early intervention, psychological factors in disease onset, and structured clinical protocols to prevent progression to necrotizing periodontitis.
