Therapeutic Pulpotomy

Dental procedures are critical in maintaining oral health, and one such essential procedure is the therapeutic pulpotomy. This procedure is often confused with other dental treatments but serves a distinct purpose, especially in pediatric dentistry. Understanding what a therapeutic pulpotomy entails, its indications, benefits, and aftercare can help patients and caregivers make informed decisions about their dental health. This comprehensive guide delves into the details of therapeutic pulpotomy, providing a thorough understanding of its role and importance.

What is a Therapeutic Pulpotomy?

A therapeutic pulpotomy is a dental procedure performed to treat a tooth with an infected or inflamed pulp. The goal is to remove the affected portion of the pulp within the crown of the tooth while preserving the healthy pulp tissue in the roots. This procedure is commonly performed on primary (baby) teeth but can also be indicated for young permanent teeth under certain conditions.

Unlike a complete pulpectomy or a root canal, which involves the removal of all the pulp tissue, a therapeutic pulpotomy focuses on maintaining the vitality of the tooth by keeping the healthy pulp in the roots intact. This helps in preserving the tooth’s functionality and structure while eliminating pain and infection.

Indications for Therapeutic Pulpotomy

Therapeutic pulpotomy is indicated in various situations where the pulp is affected but not entirely compromised. Some common indications include:

• Extensive Tooth Decay: When decay has penetrated the enamel and dentin, reaching the pulp chamber.
• Trauma: Teeth that have suffered trauma, leading to pulp exposure or inflammation.
• Severe Pain and Sensitivity: Persistent tooth pain or sensitivity to hot and cold that suggests pulp involvement.
• Preservation of Primary Teeth: Maintaining primary teeth to ensure proper spacing and alignment for permanent teeth.
• Inflammation Confined to the Crown: When the inflammation is limited to the crown portion of the tooth, with healthy pulp tissue remaining in the roots.

The Therapeutic Pulpotomy Procedure

The therapeutic pulpotomy procedure is relatively straightforward and can usually be completed in a single visit. Here are the steps involved:

1. Diagnosis and Evaluation:
   • Clinical Examination: The dentist examines the tooth, assesses symptoms, and checks for signs of pulp exposure or infection.
   • X-Rays: Dental X-rays are taken to evaluate the extent of decay or damage and to ensure that the roots are healthy.
2. Anesthesia:
   • Local anesthesia is administered to numb the affected tooth and surrounding tissue, ensuring a pain-free procedure.
3. Isolation:
   • The tooth is isolated using a rubber dam to keep it dry and free from saliva during the procedure.
4. Access Opening:
   • A small opening is made in the tooth’s crown to access the pulp chamber.
5. Pulp Removal:
   • The infected or inflamed pulp tissue is carefully removed from the crown portion of the tooth, leaving the healthy pulp in the roots intact.
6. Disinfection:
   • The pulp chamber is disinfected to eliminate any remaining bacteria and reduce the risk of reinfection.
7. Placement of Medicament:
   • A medicament, such as formocresol, ferric sulfate, or mineral trioxide aggregate (MTA), is placed in the pulp chamber to promote healing and protect the remaining pulp tissue.
8. Restoration:
   • The tooth is then restored with a suitable filling material, such as composite resin, and in some cases, a stainless steel crown is placed to provide additional protection and strength.

Materials Used in Therapeutic Pulpotomy

Several materials can be used in therapeutic pulpotomy to promote healing and protect the pulp tissue. The choice of material depends on various factors, including the dentist’s preference, the specific case, and the patient’s overall health. Common materials include:

What are the two types of pulpotomy?

There are two main types of pulpotomy procedures commonly performed in dentistry, each tailored to specific clinical scenarios and tooth conditions:

1. Vital Pulpotomy:
   • Indications: Vital pulpotomy is indicated when the coronal pulp is inflamed or infected but the root pulp remains healthy and vital. It is typically performed in primary teeth (baby teeth) and young permanent teeth with reversible pulpitis or minimal pulp exposure.
   • Procedure:
     • The infected or inflamed coronal pulp tissue is carefully removed using a sterile spoon excavator or similar instrument.
     • The remaining healthy root pulp tissue is left intact to maintain the tooth’s vitality.
     • A biocompatible medicament such as calcium hydroxide or mineral trioxide aggregate (MTA) is applied to the remaining pulp tissue to promote healing and preserve vitality.
     • The pulp chamber is sealed with a suitable base material, and the tooth is restored with a filling or crown to protect it from further decay or damage.
   • Goals: The primary goal of vital pulpotomy is to preserve the vitality of the remaining root pulp tissue, promote healing, and maintain the function of the tooth until natural exfoliation in primary teeth or until the tooth matures in young permanent teeth.
2. Non-Vital Pulpotomy:
   • Indications: Non-vital pulpotomy is performed when the coronal pulp is necrotic or severely infected, but the root pulp remains unaffected and vital. It is typically indicated in primary teeth with extensive decay or infection.
   • Procedure:
     • The necrotic or infected coronal pulp tissue is completely removed to eliminate the source of infection.
     • A strong antibacterial medicament such as formocresol or ferric sulfate is applied to the remaining root pulp to disinfect the pulp chamber.
     • The pulp chamber is sealed with a suitable base material, and the tooth is restored with a filling or crown to maintain its function and prevent reinfection.
   • Goals: Non-vital pulpotomy aims to manage the infection, prevent its spread to surrounding tissues, and maintain the tooth’s function until natural exfoliation.

In summary, vital pulpotomy aims to preserve the vitality of the remaining healthy root pulp tissue, while non-vital pulpotomy focuses on managing infection in the coronal pulp while maintaining the health of the root pulp.

What is the difference between pulpotomy and IPT?

Pulpotomy:

• Definition: Pulpotomy involves the partial removal of the diseased or inflamed pulp tissue from the coronal part of the tooth, leaving the healthy root pulp intact.
• Indications: Typically performed in primary teeth and young permanent teeth with reversible pulpitis or minimal pulp exposure.
• Procedure: Removal of the coronal pulp, application of a medicament to the remaining root pulp, and sealing of the pulp chamber to promote healing and preserve vitality.
• Goal: To maintain the vitality of the remaining root pulp tissue and avoid premature tooth loss.

Indirect Pulp Treatment (IPT):

• Definition: Indirect Pulp Treatment (IPT) is a conservative approach used when decay or caries has approached the pulp but has not yet reached it. It involves removing the outer layer of decayed dentin and placing a protective material (such as calcium hydroxide or glass ionomer cement) over the affected dentin to encourage remineralization and create a barrier between the tooth’s pulp and the bacteria.
• Indications: IPT is typically performed in primary teeth and occasionally in young permanent teeth with deep carious lesions where the pulp is not yet exposed but is at risk of exposure during cavity preparation.
• Procedure: Removal of decayed dentin, application of a protective liner or base over the affected dentin, and restoration of the tooth with a filling material.
• Goal: To maintain the vitality of the pulp and promote dentin remineralization, avoiding the need for more invasive procedures like pulpotomy or pulpectomy.

In summary, pulpotomy involves the removal of infected or inflamed pulp tissue, while IPT is a conservative treatment aimed at preserving the vitality of the pulp and promoting healing without directly exposing or removing pulp tissue.

What is the medicament for pulpotomy?

The choice of medicament for pulpotomy depends on several factors, including the clinical situation, patient age, and dentist’s preference. Commonly used medicaments for pulpotomy include:

1. Mineral Trioxide Aggregate (MTA):
