Understanding Necrotizing Gingivitis in Children
Necrotizing gingivitis, often referred to as NG or sometimes overlapping with acute necrotizing ulcerative gingivitis, represents a rare but aggressive form of periodontal disease. It involves the sudden onset of ulceration and necrosis primarily affecting the interdental gingival papillae, leading to intense pain, bleeding, and the formation of removable pseudomembranes. In paediatric patients, this condition demands prompt attention because untreated cases can progress to more severe necrotizing periodontitis or even stomatitis, involving bone loss and deeper tissue destruction.
The estimated global prevalence remains below 1%, yet it disproportionately affects vulnerable children in both developing and developed regions. Risk factors include poor oral hygiene, severe malnutrition, psychological stress, immunosuppression such as HIV, and in some cases, tobacco exposure or disrupted sleep patterns. Young adults and adolescents show higher incidence, but when it strikes younger children, the impact on growth, nutrition, and quality of life can be significant.
Why Paediatric Cases Pose Unique Challenges
Managing NG in children differs from adult protocols due to anatomical differences, developmental considerations, and the frequent presence of systemic factors. Children may present with fever, lymphadenopathy, malaise, and excessive salivation, complicating diagnosis and compliance with treatment. Standard approaches like mechanical debridement under local anaesthesia require adaptation for younger patients, while antibiotic selection must account for age-appropriate dosing and potential side effects.
Traditional literature often extrapolates adult guidelines to paediatric settings, creating gaps in evidence-based care. This scarcity of dedicated paediatric research underscores the need for specialized protocols that balance efficacy with safety and long-term oral health outcomes.
Key Findings from the Scoping Review
A comprehensive scoping review of available literature on NG in paediatric patients examined seven key sources, including case reports, guidelines, and prior reviews. The analysis revealed a striking paucity of high-quality, paediatric-specific studies. Most existing evidence derives from adult populations or anecdotal reports, highlighting an urgent gap in research tailored to children's unique physiological and psychological needs.
Despite these limitations, the review synthesizes current understanding of aetiology—predominantly opportunistic bacteria including spirochetes and Gram-negative species like Prevotella intermedia and Fusobacterium—and emphasizes the importance of early intervention to prevent progression. It also evaluates treatment modalities ranging from local debridement and chlorhexidine rinses to systemic antibiotics.
The Innovative Decision Tree Protocol
Building on the review findings, researchers developed a practical decision tree protocol for NG management in paediatric patients. The algorithm branches based on the presence or absence of systemic compromise, such as fever or lymphadenopathy.
- In cases without systemic involvement, emphasis falls on local therapies including gentle ultrasonic debridement, antiseptic mouth rinses, and rigorous oral hygiene instruction.
- When systemic symptoms are present, systemic antibiotics—typically metronidazole as the first-line choice due to its efficacy against anaerobes, sometimes combined with amoxicillin—become integral alongside local measures.
This structured approach promotes individualized care, reducing recurrence risk and supporting faster resolution of acute symptoms.

Real-World Evidence: Two Illustrative Case Reports
The review incorporates two detailed case reports demonstrating the protocol's effectiveness. Both paediatric patients presented with classic NG signs and received tailored interventions guided by the decision tree. Treatment incorporated antibiotics when indicated, combined with periodontal ozone therapy as an adjunct to promote tissue healing and reduce bacterial load.
Outcomes included rapid symptom relief, resolution of necrotic lesions, and successful transition to maintenance phases. Follow-up showed sustained gingival health, validating the protocol's utility in real clinical scenarios. Ozone's role as an adjunct stands out, leveraging its antimicrobial and immunomodulatory properties to enhance conventional care without additional systemic burden.
Integrating Ozone Therapy into Paediatric Care
Ozone therapy emerges as a promising supportive tool. This triatomic oxygen molecule disrupts bacterial cell walls, stimulates tissue oxygenation, and modulates immune responses when applied at appropriate concentrations. In dental contexts, it serves as an adjuvant for periodontal conditions, offering benefits in healing and reducing reliance on prolonged antibiotic courses.
Its application in NG cases aligns with growing interest in minimally invasive adjuncts that support paediatric patients' comfort and compliance.
Broader Implications for Research and Clinical Practice
This work fills a critical void by spotlighting the evidence gap and proposing actionable solutions. For clinicians, the decision tree offers a clear, evidence-informed framework adaptable across settings. For researchers, it signals opportunities for randomized controlled trials, longitudinal studies on recurrence, and exploration of ozone dosing specific to children.
In educational contexts, integrating such protocols into dental curricula can better prepare future practitioners for rare but high-impact conditions like paediatric NG.
Future Outlook and Recommendations
Advancing care for NG in children requires sustained investment in paediatric-focused research. Priorities include developing age-specific diagnostic criteria, evaluating long-term outcomes of the decision tree, and exploring adjuncts like ozone in larger cohorts. Multidisciplinary collaboration involving paediatric dentists, immunologists, and public health experts could further refine prevention strategies targeting malnutrition and stress in at-risk populations.
Ultimately, standardized yet flexible protocols promise to improve prognosis, reduce complications, and enhance quality of life for affected children worldwide.

Conclusion
The scoping review and accompanying case reports on necrotizing gingivitis in paediatric patients mark a meaningful step forward. By addressing research scarcity and introducing a practical decision tree with supportive ozone therapy, this contribution equips the dental community with tools for more effective, compassionate management. Continued innovation and evidence-building will be essential to protect young smiles and support optimal oral health development.
