Odontogenic infections are a common reason for dental and emergency visits across all age groups. However, there are critical differences in how these infections manifest, spread, and are managed in children versus adults.

In comparison, the metabolism of a drug in a child is different from that of an adult, so the administration of an antibiotic should be taking into account the diagnosis, age and weight of the pediatric patient.This article outlines the major anatomical, clinical, and therapeutic distinctions between pediatric and adult odontogenic infections, highlighting the need for age-specific diagnosis and treatment approaches.

✅ Anatomical and Physiological Differences
The anatomical structure of the maxillofacial region changes significantly from childhood to adulthood:
° In children, the jawbones are more porous and less mineralized, allowing for faster spread of infections into adjacent soft tissues (Borkar et al., 2020).
° In adults, denser bone structure typically leads to more localized infections, often presenting as periapical abscesses.
Additionally, primary teeth in children are closely associated with the developing permanent tooth buds, making untreated infections a potential threat to future dental development (Andreadis et al., 2021).

The root causes of odontogenic infections vary by age group:
° In children, the most common causes include deep caries in primary teeth, dental trauma, and issues related to tooth eruption.
° In adults, infections are often linked to chronic periapical disease, periodontal conditions, or post-extraction complications (Flynn, 2011).
° Systemic risk factors such as diabetes, cancer therapy, or immunosuppression increase susceptibility to severe odontogenic infections, especially in adults (Kuriyama et al., 2019).

The way odontogenic infections present and evolve differs significantly between children and adults:
° Pediatric patients often show rapid infection spread, leading to facial cellulitis, periorbital involvement, or submandibular swelling, frequently accompanied by fever and irritability (Auluck et al., 2020).
° Adults are more likely to present with localized abscesses, although delayed treatment can result in deep neck space infections or even mediastinitis.
Airway compromise is rare but poses a greater threat in adults due to fully developed fascial planes and deeper anatomical spaces.

➤ Diagnosis
Diagnostic evaluation includes detailed history, clinical examination, and imaging such as periapical or panoramic X-rays. CT scans are warranted in advanced or deep space infections.
° In children, clinicians must assess tooth eruption stage and the proximity of infection to permanent tooth buds.
° In adults, factors such as past root canal treatments or the presence of periodontal disease are important in diagnosis.
➤ Treatment Approach
Treatment focuses on eliminating the source of infection (via extraction, root canal, or incision and drainage), systemic support, and appropriate antibiotic therapy.
° For pediatric patients, first-line antibiotics include amoxicillin or amoxicillin-clavulanate. Tetracyclines are contraindicated due to their adverse effects on tooth development (AAPD, 2022).
° In adults, a wider range of antibiotics can be used, including clindamycin for penicillin-allergic patients or metronidazole for anaerobic coverage.
Timely intervention in both groups is crucial to avoid systemic complications and long-term morbidity.

Anatomical, immunological, and developmental factors necessitate different clinical strategies when managing odontogenic infections in children and adults. In children, protecting the integrity of developing permanent teeth and facial structures is critical, requiring more conservative and preventive approaches. In adults, the presence of comorbidities and a higher likelihood of chronic infections demand comprehensive evaluation and individualized care.
Additionally, odontogenic infections continue to be a significant public health concern, especially when early dental care is neglected. Preventive dentistry, public education, and timely treatment are key to reducing the prevalence and severity of these infections across all age groups.
💡 Conclusion
While pediatric and adult odontogenic infections share a bacterial origin, they differ markedly in presentation, progression, and treatment needs. Dental professionals must understand these distinctions to provide safe, effective, and age-appropriate care. A tailored treatment approach not only improves clinical outcomes but also minimizes complications, especially in growing children and medically compromised adults.
