Minimally Invasive Pulpotomy in Symptomatic Teeth: Is It Possible?

Vital pulp therapy (VPT) has undergone a significant change in recent years. Historically, teeth with symptoms traditionally diagnosed as irreversible pulpitis were generally treated with root canal treatment or extraction.

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

Current evidence indicates that selected mature permanent teeth with symptomatic pulpitis may retain sufficient reparative potential to be managed with pulpotomy.

However, minimally invasive pulpotomy should not be regarded as a single standardized technique. The term is better understood as a tissue-preserving therapeutic approach in which the amount of pulp removed is limited to the tissue considered clinically compromised, while maintaining the vitality of the remaining pulp.
This distinction is important because Cvek partial pulpotomy represents a specific historical technique for partial removal of exposed coronal pulp, particularly in traumatic pulp exposures, whereas contemporary pulpotomy protocols have expanded into the management of cariously exposed mature permanent teeth with symptoms indicative of irreversible pulpitis.

✅ What Is Minimally Invasive Pulpotomy?
A minimally invasive approach to pulpotomy aims to preserve the maximum amount of viable pulp compatible with effective removal of inflamed tissue and achievement of hemostasis.
The amount of tissue removed is therefore not determined exclusively by a predefined depth. Instead, it may be adjusted according to the clinical condition of the pulp after exposure.
Three concepts should be distinguished:

Procedure	Main Characteristic	Typical Clinical Context
Cvek partial pulpotomy	Limited removal of superficial exposed pulp, historically involving approximately 1–2 mm of tissue.	Traumatic pulp exposure, particularly in permanent incisors.
Contemporary partial pulpotomy	Removal of a limited amount of coronal pulp according to tissue condition and the ability to achieve hemostasis.	Selected carious pulp exposures, including mature teeth with symptomatic pulpitis.
Full pulpotomy	Removal of the entire coronal pulp to the level of the canal orifices while preserving the radicular pulp.	Mature teeth in which more extensive coronal pulp removal is required.

The Cvek technique should therefore not be used synonymously with minimally invasive pulpotomy. Its historical evidence base is primarily associated with traumatic pulp exposures, whereas contemporary partial pulpotomy has been investigated in mature permanent teeth with carious exposure and symptomatic pulpitis.

✅ Can Symptomatic Teeth Be Treated With a Minimally Invasive Approach?
Yes, in selected cases.
The current evidence challenges the assumption that symptoms traditionally associated with irreversible pulpitis automatically indicate complete loss of pulpal healing potential. The AAE recognizes that VPT may be considered in appropriately selected mature teeth previously diagnosed with irreversible pulpitis and emphasizes direct assessment of the exposed pulp as an important component of case selection.
A 2024 systematic review and meta-analysis found favorable outcomes for pulpotomy in mature permanent teeth diagnosed with irreversible pulpitis, although the authors emphasized limitations in the available evidence and heterogeneity among studies.
Importantly, the evidence does not mean that every symptomatic tooth is a candidate for partial pulpotomy. Rather, pulpal status must be reassessed after exposure and tissue removal.

✅ Partial Pulpotomy in Symptomatic Mature Teeth
Contemporary randomized clinical trials provide increasing evidence supporting partial pulpotomy in selected mature permanent teeth with symptoms indicative of irreversible pulpitis.
In a randomized trial involving 50 mature molars, partial pulpotomy using Biodentine achieved an 88% success rate at 12 months, compared with 91.6% for full pulpotomy, with no statistically significant difference between groups.
Another randomized trial involving 106 mature mandibular molars reported 80.8% success for partial pulpotomy and 89.8% for complete pulpotomy at 12 months. Although the numerical difference favored complete pulpotomy, it was not statistically significant. The authors concluded that partial pulpotomy may be attempted because of its more conservative nature.
More recent research has also investigated how much pulp should be removed during partial pulpotomy. A 2025 randomized clinical trial compared restricted partial pulpotomy, in which approximately 2–3 mm of superficial pulp was removed only at the exposure site, with an extended approach involving removal of 2–3 mm of superficial pulp throughout the pulp chamber. This reflects the continuing shift toward determining the extent of tissue removal according to biological rather than purely mechanical criteria.

✅ Clinical Determinants of Success
The key issue is not simply how little pulp can be removed, but whether the remaining pulp is capable of healing.

Clinical Factor	Importance in Treatment Selection
Preoperative diagnosis	Establishes the initial pulpal and periapical diagnosis but cannot determine the exact histological extent of inflammation.
Direct pulp assessment	Provides additional information after pulp exposure and removal of clinically compromised tissue.
Hemostasis	Controlled bleeding after pulp amputation supports proceeding with vital pulp therapy; persistent bleeding requires reassessment.
Aseptic isolation	Reduces microbial contamination of the exposed pulp and treatment field.
Extent of inflammation	Helps determine whether a limited partial pulpotomy or more extensive coronal pulp removal is appropriate.
Biomaterial	Calcium silicate-based hydraulic cements are widely used in contemporary vital pulp therapy.
Coronal seal	An effective definitive restoration is essential to prevent bacterial leakage and protect the treated pulp.

In randomized clinical studies, inability to control bleeding within a predefined period has been used as a criterion for abandoning the planned pulpotomy protocol. For example, one trial required hemostasis within six minutes before proceeding with treatment.
However, hemostasis time should not be interpreted as an absolute biological threshold. It is a clinical decision aid rather than a direct histological measurement of pulpal inflammation.

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

✅ A Contemporary Minimally Invasive Protocol
A tissue-preserving approach should follow a biologically guided sequence:

1. Establish the pulpal and periapical diagnosis.
2. Obtain appropriate preoperative radiographs.
3. Achieve rubber dam isolation and aseptic control.
4. Remove infected dentin and expose the pulp when indicated.
5. Remove the clinically compromised coronal pulp.
6. Assess the remaining tissue and establish hemostasis.
7. Determine whether partial or full pulpotomy provides the most appropriate level of tissue removal.
8. Apply an appropriate calcium silicate-based biomaterial.
9. Provide a durable definitive coronal restoration.
10. Perform clinical and radiographic follow-up.
This approach is consistent with the contemporary VPT concept that direct visualization of pulp tissue after exposure can contribute to treatment selection, because conventional sensibility testing cannot establish the histological status of the pulp with sufficient precision.

✅ Is the Cvek Technique the Same Procedure?
No.
The Cvek partial pulpotomy is a specific form of partial pulpotomy historically associated with traumatic crown fractures and exposed vital pulp, particularly in permanent incisors. The classic procedure involved removal of a small superficial portion of exposed pulp followed by placement of a pulp-capping material.
Long-term clinical studies have demonstrated favorable outcomes for partial pulpotomy in traumatized permanent incisors.
Contemporary partial pulpotomy for symptomatic carious teeth is conceptually related because both procedures preserve vital pulp tissue. However, they should not be treated as identical techniques because their indications, clinical circumstances, and evidence bases differ.

Thus:
Cvek partial pulpotomy = a specific partial pulpotomy technique.
Minimally invasive pulpotomy = a broader tissue-preservation approach that may involve partial or, when clinically necessary, full pulpotomy.

It covers indirect and direct pulp treatment approaches, along with coronal pulpotomy, offering clinicians evidence-based options for managing deep carious lesions while preserving tooth vitality.

💬 Discussion
The most important change in contemporary VPT is not the introduction of a new pulpotomy technique, but the recognition that pulpal inflammation is biologically heterogeneous. Clinical symptoms alone cannot reliably determine whether all remaining pulp tissue has lost its capacity for healing.
Consequently, a diagnosis such as symptomatic irreversible pulpitis should not automatically be interpreted as evidence that every portion of the pulp is irreversibly damaged. The AAE and contemporary evidence support combining preoperative diagnosis with direct intraoperative assessment when VPT is being considered.
The evidence supporting partial pulpotomy is particularly relevant to the minimally invasive concept. Randomized trials have demonstrated favorable short-term outcomes and, in several studies, no statistically significant difference between partial and full pulpotomy.
Nevertheless, the current evidence does not justify assuming that partial pulpotomy is universally superior. Some studies report numerically higher success with full pulpotomy, while follow-up periods remain relatively short in much of the literature. A 2024 meta-analysis likewise concluded that the evidence is promising but affected by heterogeneity and methodological limitations.
Therefore, the objective of minimally invasive pulpotomy should not be “remove as little pulp as possible”. The biologically appropriate objective is to remove compromised tissue while preserving the greatest amount of healthy, functional pulp that can predictably remain viable.

✍️ Conclusion
Minimally invasive pulpotomy is a valid contemporary concept within vital pulp therapy, but it is not synonymous with the Cvek technique.
The Cvek procedure is a specific form of partial pulpotomy historically used for traumatic pulp exposures. Contemporary minimally invasive pulpotomy encompasses a broader tissue-preserving philosophy that may involve partial or full pulpotomy according to the clinical condition of the pulp.
In selected mature permanent teeth with symptoms indicative of irreversible pulpitis, current evidence supports pulpotomy as a potential alternative to root canal treatment. However, successful treatment depends on appropriate case selection, asepsis, direct pulp assessment, effective hemostasis, suitable biomaterials, and a reliable coronal seal.

🎯 Clinical Recommendations
▪️ Do not use Cvek partial pulpotomy and minimally invasive pulpotomy as interchangeable terms.
▪️ Consider contemporary partial pulpotomy in selected symptomatic mature teeth when the remaining pulp demonstrates favorable clinical characteristics after tissue removal.
▪️ Do not impose a predetermined depth of tissue removal when the clinical condition of the pulp indicates that additional removal is necessary.
▪️ Use hemostasis and direct pulp assessment as important intraoperative decision points rather than relying exclusively on the preoperative diagnosis.
▪️ If a limited partial pulpotomy does not provide a suitable pulpal wound or controlled hemostasis, progress to a more extensive pulpotomy or reconsider VPT, according to the clinical circumstances.
▪️ Consider long-term follow-up essential because short-term symptom resolution does not by itself demonstrate sustained pulp vitality.

Current recommendations distinguish treatment according to pulpal diagnosis, tooth restorability, root development, and the expected lifespan of the tooth.
For primary teeth, evidence increasingly supports indirect pulp treatment and calcium-silicate cement pulpotomy for appropriately selected vital teeth. In immature permanent teeth, maintaining pulp vitality is particularly important because it permits continued root maturation and apexogenesis.

✅ Pulpal Diagnosis in Children
Accurate diagnosis is the foundation of pediatric endodontic treatment. Clinical history, symptoms, clinical examination, radiographic findings, and, when appropriate, pulp sensibility testing should be interpreted collectively.
In primary teeth, symptoms may be less predictable than in permanent teeth; therefore, clinical and radiographic findings should not be interpreted in isolation. Important findings include spontaneous or lingering pain, abnormal mobility, swelling, sinus tract formation, furcation radiolucency, pathological root resorption, and changes in the supporting tissues.

The principal diagnostic categories include:
▪️ Normal pulp
▪️ Reversible pulpitis
▪️ Symptomatic or asymptomatic irreversible pulpitis
▪️ Pulp necrosis
▪️ Previously treated or previously initiated therapy, when applicable
The treatment objective is not simply to eliminate pain but to control infection and preserve the tooth and surrounding tissues for as long as clinically appropriate.

✅ Vital Pulp Therapy in Primary Teeth
For primary teeth with normal pulp or reversible pulpitis, contemporary management favors conservative approaches that preserve radicular pulp vitality.

Indirect Pulp Treatment
Indirect pulp treatment (IPT) is particularly useful for deep carious lesions when the pulp is considered vital and there are no clinical or radiographic findings indicating irreversible disease.
Selective caries removal reduces the probability of pulp exposure while allowing the remaining dentin and pulp-dentin complex to maintain biological activity. The 2024 AAPD guideline provides strong evidence supporting IPT for deeply carious primary teeth.

Pulpotomy
A pulpotomy removes the coronal pulp while preserving the radicular pulp. It remains an important treatment for vital primary teeth when caries removal results in exposure and the remaining radicular pulp is considered capable of healing.
Current evidence favors calcium-silicate materials, particularly mineral trioxide aggregate (MTA) and Biodentine, over several traditional pulpotomy medicaments. The AAPD 2024 guideline found higher 24-month success with IPT or calcium-silicate cement pulpotomy compared with several alternative approaches.
Consequently, calcium-silicate cement pulpotomy has become a major contemporary approach in primary-tooth vital pulp therapy.

✅ Non-Vital Pulp Therapy in Primary Teeth
When a primary tooth presents with irreversible pulpitis or pulp necrosis, treatment generally requires removal of infected or necrotic tissue.

Pulpectomy
Pulpectomy involves removal of the pulp from the entire root canal system, followed by canal debridement, disinfection, and filling with a resorbable material.
Hand and rotary instrumentation can both be used. Evidence reviewed by the AAPD indicates that rotary instrumentation can substantially reduce instrumentation time without demonstrating a significant difference in filling quality or overall treatment success compared with manual instrumentation.
Irrigation is an essential component of canal disinfection. Sodium hypochlorite may be used at appropriate concentrations, but because of its tissue toxicity, extrusion beyond the root apex must be avoided. The final obturation material should be compatible with the physiologic resorption of primary roots.

Lesion Sterilization and Tissue Repair
Lesion sterilization and tissue repair (LSTR) is a non-instrumentation or minimally instrumented approach involving antimicrobial agents. It may have a role in selected primary teeth, particularly when conventional pulpectomy is unfavorable.
However, the evidence indicates that its application should be selective. LSTR may be advantageous in teeth with preoperative root resorption, whereas conventional pulpectomy performs better when roots remain intact. Close clinical and radiographic follow-up is therefore essential.

✅ Vital Pulp Therapy in Immature Permanent Teeth
The management of immature permanent teeth differs fundamentally from that of primary teeth because preservation of vital pulp tissue can allow continued physiologic root development.

For permanent teeth with normal pulp or reversible pulpitis, contemporary options include:
▪️ Indirect pulp treatment
▪️ Direct pulp capping
▪️ Partial pulpotomy
▪️ Complete pulpotomy
The 2025 AAPD guideline indicates that selective caries removal is strongly recommended for deep caries in permanent teeth with normal pulp or reversible pulpitis. When pulp exposure occurs, calcium-silicate materials may be used for direct pulp capping, partial pulpotomy, or complete pulpotomy.

Partial Pulpotomy
Partial pulpotomy removes a limited portion of inflamed coronal pulp while preserving deeper healthy tissue. It is particularly relevant for traumatic exposures and selected carious exposures.
For traumatic exposures, the Cvek technique removes approximately 1–3 mm of superficial inflamed pulp, or more when necessary to reach healthy tissue. Hemostasis and a biologically compatible pulp-capping material are then required.

Complete Pulpotomy
Contemporary evidence has expanded the potential indications for complete pulpotomy in permanent teeth. In selected teeth with symptoms traditionally associated with irreversible pulpitis, complete pulpotomy may be considered when the pulp remains vital and adequate hemostasis can be achieved.
The 2025 AAPD guideline recommends calcium-silicate materials for vital pulp therapy and emphasizes appropriate hemostasis, with sodium hypochlorite recommended for pulp-hemostasis procedures.

✅ Apexogenesis, Apexification, and Regenerative Endodontics
The primary biological objective in an immature permanent tooth with vital pulp is apexogenesis, allowing continued root development and thickening of the dentinal walls.
When the pulp is necrotic, conventional treatment may compromise further physiologic root development. Depending on the clinical situation, regenerative endodontic procedures or apexification may therefore be considered.
Regenerative approaches aim to promote continued root maturation and development of the apical region. Treatment selection should consider the stage of root development, infection control, restorability, and the long-term prognosis of the tooth. The current AAPD framework includes apexification and regenerative endodontics among the principal options for non-vital immature permanent teeth.

✅ Contemporary Materials and Techniques

Clinical Situation	Preferred Contemporary Approach	Key Consideration
Deep caries, vital primary tooth	Indirect pulp treatment	Selective caries removal and an effective coronal seal
Pulp exposure in a vital primary tooth	Calcium-silicate pulpotomy	MTA or another appropriate calcium-silicate cement
Necrotic primary tooth	Pulpectomy	Effective disinfection and resorbable obturation
Immature permanent tooth, vital pulp	Vital pulp therapy	Preserve vitality and promote apexogenesis
Traumatic pulp exposure	Partial pulpotomy	Remove inflamed superficial pulp and obtain hemostasis
Necrotic immature permanent tooth	Regenerative endodontics or apexification	Root maturity, infection control, and long-term prognosis

Table based on current AAPD recommendations and contemporary evidence.

✅ Technical Principles for Pediatric Endodontic Procedures
Successful pediatric endodontics depends not only on treatment selection but also on infection control, isolation, tissue preservation, and coronal sealing.

Isolation
Rubber dam isolation should be considered fundamental whenever endodontic treatment is performed. It improves moisture control, reduces microbial contamination, and protects the child from aspiration or ingestion of instruments and materials.

Magnification
Magnification can improve visualization of pulp tissue and facilitate assessment during vital pulp procedures. Its value is particularly relevant when determining the quality of the remaining pulp and controlling hemorrhage.

Hemostasis
In vital pulp therapy, controlled hemorrhage is an important clinical indicator. Persistent bleeding may indicate more extensive inflammation and influence the decision to remove additional pulp tissue or change the treatment approach.

Coronal Seal
A durable coronal restoration is essential because bacterial leakage can compromise otherwise successful pulp therapy. The definitive restoration should provide an effective seal and sufficient structural protection for the expected life of the tooth.

💬 Discussion
The contemporary concept of pediatric endodontics is increasingly centered on biological preservation rather than routine removal of the entire pulp. This is particularly evident in the growing evidence supporting IPT and calcium-silicate pulpotomy in primary teeth and vital pulp therapy in immature permanent teeth.
The 2024 AAPD guideline found high-certainty evidence favoring IPT and calcium-silicate cement pulpotomy for deeply carious vital primary teeth. It also moved clinical practice further away from several traditional medicaments, including calcium hydroxide as a primary pulpotomy medicament and toward calcium-silicate materials.
At the same time, the 2025 AAPD guideline for permanent teeth reflects an important conceptual change: irreversible pulpitis does not automatically require complete pulpectomy or conventional root canal treatment when the pulp remains clinically viable and the tooth can be appropriately managed. Selected cases may benefit from partial or complete pulpotomy using calcium-silicate materials.
Nevertheless, evidence quality is not uniform across all pediatric endodontic interventions. Treatment decisions should therefore integrate the best available evidence with clinical diagnosis, tooth restorability, root development, infection status, patient cooperation, and long-term prognosis.

🎯 Clinical Recommendations
1. Prioritize biological diagnosis over symptoms alone. Combine history, clinical examination, radiographic findings, and pulp testing when appropriate.
2. Preserve vital pulp tissue whenever predictable healing is possible, particularly in immature permanent teeth where vitality supports continued root development.
3. Consider IPT as a first-line approach for appropriately selected deeply carious vital primary teeth, avoiding unnecessary pulp exposure.
4. When pulpotomy is indicated in a primary tooth, calcium-silicate cements such as MTA or Biodentine should be strongly considered based on current evidence.
5. For necrotic primary teeth, select pulpectomy or carefully indicated LSTR according to root resorption, infection, restorability, and prognosis.
6. In immature permanent teeth, consider partial or complete pulpotomy before conventional root canal treatment when the pulp remains potentially reparable and adequate hemostasis can be achieved.
7. Do not compromise apical development unnecessarily. Preservation of pulp vitality in immature permanent teeth should remain a major treatment objective.
8. Establish an effective coronal seal and schedule clinical and radiographic follow-up, because treatment success depends on both biological management and restoration quality.

✍️ Conclusion
Pediatric endodontics has evolved toward conservative, biologically oriented treatment. Current evidence supports indirect pulp treatment and calcium-silicate pulpotomy as important approaches for selected primary teeth, while vital pulp therapy has an increasingly important role in immature permanent teeth.
The fundamental principle is to match the intervention to the biological condition of the pulp rather than relying exclusively on historical treatment protocols. Accurate diagnosis, strict isolation, effective disinfection, appropriate biomaterials, durable coronal sealing, and systematic follow-up remain essential to achieving predictable outcomes.

Current pediatric guidelines emphasize preserving vital pulp tissue whenever predictable healing is possible. However, pulp exposure should not automatically lead to pulpotomy or extraction. A structured diagnosis is essential to select the least invasive treatment with a reasonable prognosis.

✅ Initial Assessment of Pulp Exposure
The emergency assessment should include:
▪️ History: spontaneous pain, provoked pain, duration, nocturnal pain, trauma, and previous symptoms.
▪️ Clinical examination: caries extent, pulp exposure characteristics, swelling, sinus tract, mobility, tenderness, and restorability.
▪️ Radiographic assessment: periapical or bitewing imaging when indicated to evaluate the depth of the lesion, furcation/periapical changes, root resorption, and the developing permanent successor.
▪️ Pulp assessment: determine whether the pulp appears clinically vital and whether bleeding can be controlled after exposure or tissue removal.
In primary teeth, pulpal diagnosis is particularly challenging because conventional sensibility testing has limited reliability. Therefore, clinical and radiographic findings must be interpreted together rather than relying on a single diagnostic test.

📌 Recommended Article :

Dental Article 🔽 Bioactive Materials in Pulpotomies: MTA, Biodentine and Emerging Alternatives ... Bioactive materials have transformed vital pulp therapy in pediatric dentistry. Mineral Trioxide Aggregate (MTA) and Biodentine remain the most reliable options due to their biocompatibility, sealing ability, and predictable dentin bridge formation.

✅ Emergency Treatment Options

1. Direct Pulp Cap
A direct pulp cap (DPC) may be considered when a small pulp exposure occurs in a tooth with a favorable pulpal diagnosis and adequate conditions for maintaining pulp vitality.
The exposed pulp should be protected with a biocompatible pulp-capping material, followed by an effective coronal seal. Calcium-silicate materials are increasingly used because of their biological properties.
However, the indication for DPC differs between primary and permanent teeth. Contemporary evidence supports DPC more strongly in appropriately selected permanent teeth, whereas its routine use for carious exposures in primary teeth is less predictable.

2. Partial Pulpotomy
A partial pulpotomy removes a limited portion of inflamed coronal pulp while preserving the remaining vital tissue.
This approach is particularly valuable for traumatic pulp exposures in immature permanent teeth, where maintaining vitality allows continued root development and apical maturation. IADT guidelines recommend partial pulpotomy for complicated crown fractures with pulp exposure in primary teeth when preservation of the pulp is appropriate, while treatment should be adapted to the child's age, cooperation, and clinical circumstances.

3. Full Pulpotomy
Pulpotomy is one of the principal emergency treatments for a vital primary tooth with pulp exposure when the coronal pulp is inflamed but the radicular pulp remains suitable for treatment.
The contemporary AAPD guideline supports pulpotomy as a vital pulp therapy for primary teeth with appropriate pulpal status. Calcium-silicate-based materials, including mineral trioxide aggregate (MTA), are important contemporary options. The 2024 AAPD guideline specifically recommends against calcium hydroxide as the pulpotomy medicament for primary teeth with deep caries lesions.
A key clinical determinant is hemostasis. Failure to obtain adequate control of pulpal bleeding after appropriate tissue removal should prompt reassessment of the diagnosis and treatment plan rather than simply proceeding with definitive coverage.

4. Pulpectomy or Root Canal Treatment
When the pulp is necrotic or irreversibly diseased, vital pulp therapy is no longer the appropriate treatment.
For a restorable primary tooth, pulpectomy may be indicated when there are clinical or radiographic findings consistent with irreversible pulpitis or necrosis. For permanent teeth, conventional root canal treatment may be required depending on root development and the biological status of the pulp.
In immature permanent teeth, preservation of vitality should remain a priority whenever feasible because it supports continued root maturation and dentinal wall development.

5. Extraction
Extraction should be considered when the tooth is non-restorable, has an unfavorable prognosis, presents extensive pathological root resorption, or cannot be predictably treated because of its clinical condition.
In primary teeth, treatment planning must also consider the stage of exfoliation, space requirements, occlusion, and the developing permanent successor.

✅ Emergency Decision-Making

Clinical Situation	Preferred Approach
Small exposure, favorable vital pulp, permanent tooth	Direct pulp cap or partial pulpotomy
Traumatic exposure in immature permanent tooth	Partial/full pulpotomy to preserve vitality
Vital primary tooth with suitable coronal pulp	Pulpotomy
Primary tooth with necrotic or irreversibly diseased pulp	Pulpectomy

✅ Material Selection and Hemostasis
Modern vital pulp therapy increasingly favors calcium-silicate-based biomaterials because of their biocompatibility and bioactive properties. MTA and other hydraulic calcium-silicate cements have demonstrated favorable clinical outcomes, particularly in permanent teeth.
Hemostasis is not merely a technical step; it is an important diagnostic indicator. After appropriate pulp tissue removal, persistent uncontrolled bleeding may indicate more extensive inflammation and should influence treatment selection.
A well-sealed definitive restoration is equally important. Even an appropriately performed pulp therapy can fail if the restoration permits microleakage or bacterial recontamination.

💬 Discussion
The management of pulp exposure in children has shifted toward biologically based treatment rather than automatically removing all exposed pulp tissue. The current evidence supports a conservative approach when the remaining pulp has the capacity to heal.
For primary teeth, however, clinicians should avoid directly extrapolating evidence from permanent teeth. The 2024 AAPD guideline emphasizes that treatment selection should integrate the pulpal diagnosis, clinical findings, radiographic findings, tooth restorability, and the child's circumstances.
In permanent teeth, particularly immature teeth, preservation of pulp vitality has an additional biological objective: continued root development. Contemporary AAPD recommendations indicate that direct pulp capping, partial pulpotomy, or full pulpotomy using calcium-silicate cement may be considered for selected exposed permanent teeth, including teeth at different stages of root maturation.
Therefore, the emergency objective should not simply be to "cover the nerve." The clinician should determine which pulp tissue remains biologically salvageable and which treatment provides the best opportunity for long-term tooth survival.

🎯 Clinical Recommendations
1. Do not treat pulp exposure as a diagnosis. Establish the pulpal and periapical diagnosis before selecting therapy.
2. Prioritize vital pulp preservation in appropriately selected primary and immature permanent teeth.
3. After pulp exposure, evaluate bleeding control carefully; persistent bleeding should trigger reassessment of the treatment plan.
4. Use calcium-silicate-based materials when indicated for contemporary vital pulp therapy.
5. Ensure an immediate, well-sealed definitive restoration whenever clinically appropriate.
6. In primary teeth, always consider the permanent successor, exfoliation timing, restorability, and space implications.
7. For traumatic exposures, follow established IADT trauma protocols and arrange appropriate follow-up.
8. When diagnosis, cooperation, restorability, or prognosis is uncertain, early referral to a pediatric dentist or endodontist may provide the safest approach.

✍️ Conclusion
Pulp exposure in children requires rapid but biologically guided decision-making. Direct pulp capping, partial pulpotomy, full pulpotomy, pulpectomy, and extraction each have specific indications. Current evidence increasingly supports vital pulp therapy and minimally invasive treatment when the remaining pulp has healing potential. Accurate diagnosis, effective hemostasis, appropriate biomaterials, and a durable coronal seal remain the principal determinants of successful emergency management.
