Pulp Necrosis in Primary Teeth: Diagnosis and Evidence-Based Management

Pulp necrosis in primary teeth is a common consequence of untreated caries, trauma, or chronic inflammation.

📌 Recommended Article :

Dental Article 🔽 Understanding Pulpal Diseases: Reversible Pulpitis, Irreversible Pulpitis, and Pulp Necrosis in Adults and Children ... Pulpal diseases represent a continuum of inflammatory conditions that range from reversible pulpitis to irreversible pulpitis and finally to pulp necrosis.

Early detection is crucial to prevent infection, pathological root resorption, and damage to the developing permanent successor. Understanding accurate diagnostic criteria and selecting the appropriate evidence-based treatment is essential for successful outcomes in pediatric patients.

Advertisement

✅ Etiology of Pulp Necrosis in Primary Teeth
Primary teeth are particularly vulnerable to necrosis due to:

▪️ Extensive caries progression
▪️ Anatomically thinner enamel and dentin
▪️ Traumatic dental injuries
▪️ Bacterial invasion of the pulp chamber
▪️ Chronic pulpal inflammation progressing to necrosis

📌 Recommended Article :

Video 🔽 What is Pulpitis? - Causes, symptoms, diagnosis, treatment, pathology ... It explains the main causes such as deep caries, trauma, and bacterial invasion, and details clinical symptoms like spontaneous pain, thermal sensitivity, and referred discomfort.

✅ Clinical and Radiographic Diagnosis
Accurate diagnosis relies on a combination of:

➤ Patient history (spontaneous pain, swelling, trauma)

➤ Clinical signs
▪️ Tooth discoloration (grayish)
▪️ Sinus tract
▪️ Tenderness to percussion
▪️ Gingival swelling

➤ Radiographic findings
▪️ Furcation radiolucency
▪️ Pathological root resorption
▪️ Periodontal space widening
▪️ Loss of lamina dura

In primary teeth, pulp testing methods like thermal or electric tests are unreliable, making radiographic and clinical findings essential.

📌 Recommended Article :

Dental Article 🔽 Pulpotomy vs. Pulpectomy in Primary Teeth: A Contemporary Clinical Guide ... Vital pulp therapy in primary teeth is a cornerstone of pediatric dental treatment. Among the most common procedures are pulpotomy, which conserves some of the radicular pulp, and pulpectomy, which removes all pulp tissue.

✅ Management of Pulp Necrosis in Primary Teeth
Once necrosis is confirmed, vital pulp therapies are contraindicated. Treatment options include:

➤ Pulpectomy
The preferred treatment when the tooth is restorable and the infection can be adequately controlled.
Key principles:
▪️ Thorough canal debridement
▪️ Irrigation with 2.5% sodium hypochlorite or chlorhexidine
▪️ Obturating canals with resorbable materials such as iodoform-based pastes (Vitapex/Metapex)
▪️ Final restoration, ideally with a stainless steel crown

➤ Extraction
Indicated when:
▪️ The tooth is non-restorable
▪️ There is excessive root resorption
▪️ Infection compromises the permanent successor
▪️ Patient cooperation is insufficient

➤ Antibiotics
Not routinely recommended unless:
▪️ Facial cellulitis
▪️ Systemic involvement (fever, malaise)
▪️ Spread of infection

📌 Recommended Article :

Dental Article 🔽 Clinical Pulpectomy Protocol: Updated Step-by-Step Guide ... Pulpectomy is a fundamental procedure in pediatric dentistry for treating primary teeth with pulp inflammation or necrosis. Its main goal is to eliminate infection, maintain tooth functionality until natural exfoliation, and preserve dental space.

✅ Prognosis
Successful pulpectomy has a 70–85% success rate, depending on canal anatomy, irrigation protocol, and obturation material. Failure occurs when infection persists, when restoration is inadequate, or when premature root resorption affects sealing.

📊 Comparative Table: Pulpectomy vs Extraction in Necrotic Primary Teeth

Aspect	Advantages	Limitations
Pulpectomy	Preserves arch space; maintains function; prevents premature tooth loss; avoids malocclusions	Technique sensitive; lower success in multirooted teeth; requires patient cooperation
Extraction	Quick relief of infection; avoids complex instrumentation; suitable for non-restorable teeth	Loss of arch space; risk of mesial drift; possible need for space maintainers

💬 Discussion
Managing necrotic primary teeth requires careful consideration of the child's age, behavior, the strategic value of the tooth, and the proximity to the permanent successor. Resorbable obturation materials remain essential, as non-resorbable materials can interfere with exfoliation. Current research supports the use of iodoform-based pastes due to superior antibacterial activity and predictable resorption.

📌 Recommended Article :

PDF 🔽 Manual of diagnosis and pulp treatment in non-vital primary teeth ... A correct history, clinical and radiographic evaluation is necessary in these cases to determine the appropriate treatment for these cases (dental extraction, pulpectomy, lesion sterilization tissue repair).

🔎 Recommendations

✅ Pulp Therapy Techniques

➤ Indirect Pulp Treatment (IPT)
IPT is indicated when deep caries is present but the tooth remains vital and asymptomatic. Selective caries removal minimizes pulp exposure and promotes remineralization. High-fluoride glass ionomer and resin-modified glass ionomer (RMGI) are widely used as liners.

➤ Direct Pulp Cap (DPC)
Used when a small mechanical pulp exposure occurs. Bioceramics like MTA and Biodentine create a durable dentin bridge and exhibit excellent biocompatibility.

➤ Pulpotomy
Indicated in cases of carious pulp exposure with preserved radicular pulp vitality. Popular medicaments include MTA, Biodentine, and historically formocresol, although the latter is no longer recommended due to toxicity concerns.

➤ Pulpectomy

Why Hydrogen Peroxide Should Not Be Used in Modern Endodontic Treatment: Evidence-Based Clinical Justification

This article explains why hydrogen peroxide is no longer recommended in endodontic treatments, supported by contemporary scientific evidence. The discussion includes biochemical limitations, risks, and the superiority of modern irrigants such as sodium hypochlorite and EDTA.

📌 Recommended Article :

Dental Article 🔽 Irrigants in Pediatric Pulpectomies: Key Benefits, Properties, and U.S. Commercial Brands ... This article explores the properties, benefits, and most commonly used irrigants in pediatric pulpectomies, including top commercial products used in the United States.

✅ Introduction
Hydrogen peroxide (H₂O₂) was widely used for decades in root canal therapy due to its effervescence and perceived cleaning capability. However, current endodontic literature strongly discourages its use.

Advertisement

Modern research demonstrates that H₂O₂ lacks essential chemical properties needed for root canal disinfection and introduces several clinical risks. Today, evidence-based endodontics prioritizes irrigants that dissolve tissue, eradicate biofilms, and maintain biocompatibility, criteria that hydrogen peroxide fails to meet.

Video 🔽 Pulpectomy, everything you need to know: Diagnosis, indications, and filling materials ... The video that we share details everything related to pulpectomy: diagnosis, indications and contraindications, procedure, recommended filling materials, and the importance of post-treatment follow-up.

💬 Discussion

➤ Lack of Organic Tissue Dissolution
A primary goal of irrigation is the dissolution of necrotic and vital pulp tissue. Unlike sodium hypochlorite, hydrogen peroxide cannot break down organic matter, significantly limiting its cleaning and disinfecting effects. Haapasalo et al. (2010) emphasize that irrigants must chemically degrade tissue to support mechanical instrumentation, a function H₂O₂ does not provide.

➤ Insufficient Antimicrobial Effect
Modern studies confirm that hydrogen peroxide has weak antibacterial action and is ineffective against biofilms, particularly Enterococcus faecalis, a key pathogen in persistent endodontic infections (Zehnder, 2006). This makes it inadequate as a primary or adjunctive irrigant.

➤ Risk of Oxygen Release and Subcutaneous Emphysema
Hydrogen peroxide decomposes into water and oxygen gas upon contact with catalase in tissues. This reaction may cause:
▪️ Apical extrusion of gas
▪️ Pain and pressure
▪️ Subcutaneous emphysema, a documented complication (McDonnell et al., 1982)
Because of these risks, contemporary guidelines reject its intracanal use.

➤ No Effect on Smear Layer Removal
EDTA is the gold standard for eliminating smear layer. Hydrogen peroxide cannot chelate or remove inorganic debris, leaving dentinal tubules obstructed and preventing adequate seal and penetration of medicaments or sealers (Torabinejad & Walton, 2015).

➤ Incompatibility with Sodium Hypochlorite
Studies show that mixing or alternating H₂O₂ and NaOCl results in foam production and reduced hypochlorite efficacy, compromising the cleaning process (Zehnder, 2006). This makes hydrogen peroxide incompatible with the irrigant that forms the foundation of modern endodontics.

🔎 Recommendations
Based on current evidence, clinicians should adhere to the following irrigant sequence for predictable outcomes:

1. Sodium hypochlorite (NaOCl) as the primary irrigant
2. EDTA for smear layer removal
3. Final NaOCl rinse or CHX (never mixed with NaOCl)
4. Optional activation (ultrasonic or sonic)
Hydrogen peroxide should not be included under any circumstance.

📌 Recommended Article :

Video 🔽 Apexogenesis: Step by step procedure ... Apexogenesis is a dental treatment that is performed on immature and vital permanent teeth. The objective of this treatment is to allow root growth and apical closure of the tooth.

✍️ Conclusion
Hydrogen peroxide was historically used for its effervescence, but modern endodontics no longer supports its use. Scientific literature consistently demonstrates that it lacks the biochemical properties required for effective canal disinfection, poses clinical risks due to oxygen release, and is inferior to contemporary irrigants. For safe, predictable, and evidence-based treatment, clinicians should rely on NaOCl, EDTA, and irrigant activation protocols, fully abandoning H₂O₂.

Best Materials for Pulpotomy in Primary Teeth: MTA vs. Biodentine vs. Ferric Sulfate

Pulpotomy remains the most widely used vital pulp therapy for primary teeth with reversible pulp inflammation. Selecting the best materials for pulpotomy in primary teeth is critical for long-term success and maintaining arch integrity.

📌 Recommended Article :

Dental Article 🔽 Pulpotomy vs. Pulpectomy in Primary Teeth: A Contemporary Clinical Guide ... Vital pulp therapy in primary teeth is a cornerstone of pediatric dental treatment. Among the most common procedures are pulpotomy, which conserves some of the radicular pulp, and pulpectomy, which removes all pulp tissue.

Modern evidence supports the use of bioceramic materials due to their biocompatibility and predictable healing, while traditional agents such as ferric sulfate remain in use for their cost-effectiveness. This guide compares MTA, Biodentine, and ferric sulfate, highlighting indications, advantages, limitations, and evidence-based clinical performance.

1. Overview of Pulpotomy Materials

1.1 Mineral Trioxide Aggregate (MTA)
MTA is considered the reference standard due to its biocompatibility, sealing ability, and high clinical success. It promotes dentin bridge formation and demonstrates long-term stability.

1.2 Biodentine
Biodentine is a calcium silicate–based bioceramic with faster setting time than MTA. It has strong mechanical properties and induces predictable odontogenic activity.

1.3 Ferric Sulfate (FS)
Ferric sulfate is a hemostatic agent traditionally used for primary tooth pulpotomy. It functions by forming a coagulation plug that seals blood vessels without directly affecting dentinogenesis.

This article compares partial pulpotomy and conventional (full/coronal) pulpotomy in primary teeth, focusing on definitions, technique differences, materials, clinical outcomes, and benefits.

2. Clinical Performance and Evidence

2.1 Success Rates
▪️ MTA: Studies consistently report success rates above 90% after 24–36 months.
▪️ Biodentine: Demonstrates equivalent or slightly higher success than MTA in some trials.
▪️ Ferric Sulfate: Generally achieves 70–85% success but shows higher incidence of internal resorption.

2.2 Biocompatibility and Safety
Bioceramics (MTA and Biodentine) show superior tissue response with minimal inflammatory infiltrate. Ferric sulfate may cause tissue irritation if improperly applied and lacks regenerative capabilities.

2.3 Handling and Practical Considerations
▪️ MTA has a long setting time and may discolor teeth, especially gray formulations.
▪️ Biodentine sets quickly and exhibits better color stability.
▪️ Ferric sulfate is inexpensive and requires minimal handling time.

📊 Comparative Table: MTA vs. Biodentine vs. Ferric Sulfate

Aspect	Advantages	Limitations
MTA	High biocompatibility, excellent sealing, long-term success	Long setting time, potential discoloration, higher cost
Biodentine	Fast setting, good mechanical properties, color stability	Higher cost than FS, requires strict handling protocol
Ferric Sulfate	Low cost, easy handling, effective hemostasis	Higher internal resorption risk, no regenerative effect

💬 Discussion
Current evidence clearly favors bioceramic materials (MTA and Biodentine) due to their biological compatibility, regenerative capacity, and consistently high success rates. While ferric sulfate remains a viable option in resource-limited settings, its higher association with internal resorption and lack of true tissue healing mechanisms make it less ideal compared with bioceramic alternatives.
From a clinical standpoint, the choice of material should consider cost, setting time, operator experience, patient behavior, and long-term prognosis.

📌 Recommended Article :

Dental Article 🔽 Mineral Trioxide Aggregate (MTA) in Pediatric Dentistry: Uses, Benefits, and Clinical Evidence ... Preserving primary teeth until their natural exfoliation is a key goal in pediatric dentistry. Advances in bioactive materials have made this more predictable.

✍️ Conclusion
MTA and Biodentine are the most effective and biologically favorable materials for pulpotomy in primary teeth. Biodentine offers practical advantages such as faster setting and better color stability, while MTA remains a robust gold standard with extensive evidence. Ferric sulfate may be used when bioceramics are unavailable, but it shows lower long-term predictability.
For optimal patient outcomes, clinicians should prioritize bioceramic-based pulpotomy protocols aligned with current scientific evidence.

🔎 Recommendations
▪️ Prefer Biodentine or MTA for routine pulpotomies in primary molars.
▪️ Use ferric sulfate only when bioceramic materials are unavailable or cost-prohibitive.
▪️ Avoid gray MTA formulations in esthetic zones due to discoloration risks.
▪️ Ensure effective hemostasis before applying any pulpotomy agent.
▪️ Perform periodic radiographic follow-up at 6 and 12 months, then annually.
