Stainless Steel Crowns for Kids: When and Why They’re the Best Option

Stainless Steel Crowns

Stainless steel crowns (SSCs) are one of the most reliable restorations used in pediatric dentistry, especially for baby molars that have severe decay or have undergone pulp therapy.

📌 Recommended Article :
PDF 🔽 Hall technique: Complete information for the treatment of carious primary molars ... Steel crowns are used in pediatric dentistry when primary teeth are severely damaged by dental caries. They are usually placed after pulp treatment and in hypoplastic teeth
First introduced in the 1950s, they are still widely used because they are strong, affordable, and long-lasting—often outperforming white fillings in baby teeth.

When Are Stainless Steel Crowns Used in Children?
Pediatric dentists commonly use SSCs when:

° A baby tooth has large cavities that can’t be fixed with a regular filling
° The tooth has been treated with a pulpotomy or pulpectomy
° The enamel is weak due to conditions like enamel hypoplasia or molar-incisor hypomineralization (MIH)
° The tooth has fractured due to trauma
° The child is at high risk of cavities or has special healthcare needs

Benefits of Stainless Steel Crowns for Baby Teeth

° Long-lasting protection (often until the tooth naturally falls out)
° Full coverage and excellent seal against bacteria
° Quick and easy placement in a single visit
° Ideal for young children or those who have trouble cooperating
° Lower cost than most other restorative options

How Pediatric Dentists Place a Stainless Steel Crown

1. Examine and diagnose the tooth
2. Choose the correct crown size
3. Reduce the biting surface and sides of the tooth
4. Try in the crown to ensure a proper fit
5. Cement it using glass ionomer cement
6. Check the bite and remove any excess cement

The entire process can often be done in one appointment, which is especially helpful for children with limited patience or dental anxiety.

Why Not Just Do a Filling?

White fillings (composite) or silver fillings (amalgam) may work for small cavities, but they often fail in baby teeth with major decay. Stainless steel crowns are stronger, more protective, and have a much lower failure rate—especially when the child is at high risk for future cavities.
While some parents may prefer tooth-colored crowns, research shows that SSCs have a success rate of over 90%, even after several years. Esthetic crowns like zirconia are more expensive, and not always ideal for very young or uncooperative children.

💡 Conclusion

Stainless steel crowns remain the gold standard for restoring primary molars with major damage. They offer reliable, long-term protection, are cost-effective, and reduce the need for future dental work.
If your child needs treatment for a decayed or weakened baby tooth, talk to your pediatric dentist about whether a stainless steel crown is the right option. In many cases, it’s the best way to keep their smile healthy and pain-free until the adult teeth come in.

Updated Guidelines for Antibiotic Use in Pediatric Dentistry: Evidence-Based Recommendations

Pulpotec

The judicious use of antibiotics in pediatric dentistry is crucial to combat antimicrobial resistance and ensure optimal patient outcomes. Overprescription and inappropriate antibiotic use in children contribute to the global health threat of antibiotic resistance, adverse drug reactions, and disruption of normal microbiota.

📌 Recommended Article :
PDF 🔽 Antimicrobial therapies for odontogenic infections in children and adolescents ... The use of antibiotics must be rational to avoid drug resistance of microorganisms (microbial resistance). Odontogenic infections can arise from caries or a periodontal problem, sometimes they can be due to dental trauma or iatrogenesis
This article discusses updated, evidence-based guidelines for antibiotic use in pediatric dental care, focusing on clinical indications, dosage, and the importance of antimicrobial stewardship.

Advertisement

Indications for Antibiotic Use in Pediatric Dentistry
According to the American Academy of Pediatric Dentistry (AAPD) and other professional bodies, antibiotics should be prescribed in pediatric patients only when there is clear evidence of systemic involvement or the risk of spread of odontogenic infections. The primary indications include:

° Acute facial swelling or cellulitis with systemic symptoms (fever, malaise)
° Rapidly progressing infections such as Ludwig’s angina or deep space infections
° Persistent infections not resolved by local measures alone
° Prophylaxis in patients at risk of infective endocarditis or with immunocompromising conditions

Local dental infections like localized abscesses or pulpitis do not typically require systemic antibiotics and are best managed by definitive dental treatment such as extraction or pulpectomy.

📌 Recommended Article :
PDF 🔽 Dental pain in pediatric dentistry - Assessment tools ... We share an article that reviews the important aspects of pain in pediatric dentistry, and the tools for a correct evaluation today
Commonly Recommended Antibiotics and Dosage
For pediatric patients, the most frequently recommended antibiotics are:

° Amoxicillin: 20–40 mg/kg/day divided every 8 hours, or 25–45 mg/kg/day if given twice daily
° Amoxicillin with Clavulanic Acid: Used when beta-lactamase resistance is suspected
° Clindamycin: 8–20 mg/kg/day in three divided doses (for penicillin-allergic patients)
° Azithromycin: 5–12 mg/kg on the first day followed by lower doses over 4 days

Prescribers must adjust dosages based on weight and age and consider the patient’s medical history, including allergies and hepatic or renal function.

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
Antibiotic Prophylaxis
The AAPD, following the American Heart Association (AHA) guidelines, recommends antibiotic prophylaxis for pediatric patients at high risk of infective endocarditis, especially before procedures likely to cause bleeding (e.g., tooth extractions, periodontal surgery). This includes:

° Children with prosthetic heart valves
° Previous infective endocarditis
° Certain congenital heart conditions
° Cardiac transplant recipients with valvulopathy

The standard prophylactic regimen is amoxicillin 50 mg/kg orally one hour before the procedure.

Dental Article 🔽 Severe Dental Infections: Symptoms, Treatment & Antibiotics ... Always consider patient-specific factors, such as age, weight, and allergy history, when selecting an antibiotic
💬 Discussion
Despite clear guidelines, studies reveal frequent antibiotic overprescription in pediatric dentistry. A cross-sectional study by Al-Jundi et al. (2022) indicated that many dentists prescribe antibiotics for non-indicated conditions such as reversible pulpitis, primarily due to parental expectations or time constraints. This inappropriate practice fosters resistance and increases adverse drug reactions, including gastrointestinal issues, allergic reactions, and alterations in the child’s developing microbiome.
Moreover, the COVID-19 pandemic initially led to increased remote consultations and a spike in empirical antibiotic prescriptions, further underscoring the need for robust antimicrobial stewardship programs in dental settings.
Educational interventions, integration of prescribing guidelines into electronic health systems, and continuing professional development can help reduce inappropriate prescribing practices. Collaborative efforts between pediatricians, pharmacists, and pediatric dentists are also essential.

💡 Conclusion
Antibiotic use in pediatric dentistry should be reserved for cases with systemic involvement or significant risk of progression. Adherence to updated, evidence-based guidelines is critical to minimizing resistance and ensuring patient safety. Dental professionals must prioritize definitive treatment over pharmacologic management when possible and engage in continuous education to refine prescribing practices.

➤ Limited histological regeneration: It promotes sclerosis rather than dentin bridge formation.
➤ Need for coronal seal: Success depends on proper restoration to prevent microleakage.

5. Step-by-Step Clinical Use Protocol

Step 1. Diagnose pulpitis suitable for vital pulp therapy.
Step 2. Anesthetize and isolate the tooth (rubber dam recommended).
Step 3. Access and remove coronal pulp to canal orifice level.
Step 4. Irrigate with 5% NaOCl; dry chamber.
Step 5. Prepare a salin-damped sterile cotton pellet; confirm bleeding control.
Step 6. Insert Pulpotec® paste into chamber (or canal up to ~5 mm from apex in root-filled cases) using a file.
Step 7. Place a dry cotton pellet and temporary restorative material (e.g., IRM/Cavit).
Step 8. Schedule recall after 7 days; proceed to definitive restoration—ideally stainless steel crown or adhesive restoration.
Step 9. Evaluate post-op pain at intervals (8 h, 24 h, 48 h, 3 d, 1 wk).

6. Clinical Evidence

➤ Prospective RCT (860 teeth): Pulpotec® intracanal dressing reduced incidence of inter-appointment flare-up to 1.16% at 24 h and 0.69% at 48 h, with complete pain relief by 7 days.
➤ Comparative pediatric studies:
° Pulpotec® and MTA showed 100% clinical success at 3–9 months; radiographic success favored Pulpotec® (100%) over MTA (92.9%) and formocresol (78.6%).
° At 24 months, radiographic success was 94.3% for Pulpotec®, 91.2% for MTA, 83.3% for formocresolile cotton pellet; confirm bleeding control.

💡 Conclusion
Pulpotec® is an effective and efficient pulpotomy and intracanal medicament providing high clinical and radiographic success, rapid pain relief, and broad indications. However, formaldehyde content and non-resorbability in primary teeth demand careful case selection and precise restoration. Clinicians should weigh its benefits and limitations against alternatives such as MTA or Biodentine.

Dental management
A thoughtful and professional approach is essential when treating patients with oral manifestations of STDs. Management includes:

1. Thorough clinical examination:
° Detailed intraoral inspection to identify ulcers, warts, vesicles, leukoplakia, or other lesions.
° Clinical photography (with consent) for documentation and follow-up.
2. Detailed medical history:
° Focus on systemic conditions, sexual history, and risk behaviors (e.g., smoking, drug use, multiple partners).
3. Symptomatic management:
° Topical anesthetics or systemic analgesics for pain.
° Antiviral therapy (e.g., Acyclovir, Valacyclovir) for herpes infections.
° Systemic antibiotics for bacterial STDs (e.g., syphilis or gonorrhea)—in coordination with medical treatment.
° Antifungal therapy for HIV-related oral candidiasis (e.g., Nystatin, Fluconazole).
4. Patient education and counseling:
° Clarify the link between STDs and oral health.
° Promote safer sex practices and regular testing.
° Encourage communication with physicians and follow-up care.
5. Referral and interdisciplinary care:
° Timely referral to infectious disease specialists or physicians.
° Collaboration with medical teams for systemic management.
