Things worth knowing about "Pulpotomy"

A pulpotomy is a dental procedure in which inflamed coronal pulp tissue is removed to preserve the tooth and prevent further infection.

What is a Pulpotomy?

A pulpotomy is a dental procedure in which the inflamed or infected tissue located in the crown portion of the dental pulp -- known as the pulp chamber -- is surgically removed. The dental pulp is the living inner part of the tooth, containing nerves, blood vessels, and connective tissue. The goal of the procedure is to preserve the tooth while eliminating pain and preventing the spread of infection. The healthy pulp tissue remaining in the root canals is left intact.

A pulpotomy is considered a conservative approach compared to a full root canal treatment (pulpectomy), in which the entire pulp is removed. It falls within the field of endodontics and is used in both pediatric and adult dentistry.

Indications

A pulpotomy is recommended in the following situations:

Deep cavities (caries) that have reached or compromised the pulp
Reversible pulpitis in primary or permanent teeth
Dental trauma involving pulp exposure, such as crown fractures
Primary (baby) teeth with carious pulp involvement, when the tooth should remain in the mouth until natural shedding
Permanent teeth with immature roots (apexogenesis), to allow continued root development

Procedure

The procedure typically involves the following steps:

Local anesthesia: The tooth and surrounding tissue are numbed so the patient does not feel pain during the procedure.
Rubber dam placement: A rubber dam is placed around the tooth to create a sterile environment and keep saliva away.
Caries removal: All decayed tooth material is removed completely.
Opening the pulp chamber: The dentist opens the pulp chamber and removes the inflamed coronal pulp tissue using a sterile instrument.
Hemostasis and disinfection: The wound surface is cleaned and bleeding is controlled, often using sodium hypochlorite or saline solution.
Medicament placement: The remaining pulp tissue is covered with an appropriate medicament, most commonly Mineral Trioxide Aggregate (MTA), calcium hydroxide, or bioceramics.
Sealing and restoration: The pulp chamber is sealed and the tooth is restored with a permanent filling or crown.

Pulpotomy in Children (Primary Teeth)

In pediatric dentistry, the pulpotomy is one of the most frequently performed endodontic procedures. It is used when a primary tooth has been affected by deep decay, but the root pulp remains vital and free of inflammation. The goal is to preserve the primary tooth until it is naturally shed, thereby preventing loss of space in the jaw and misalignment of permanent teeth. After a pulpotomy on a primary tooth, the tooth is usually restored with a stainless steel crown to ensure long-term stability.

Pulpotomy in Adults (Permanent Teeth)

In permanent teeth with immature roots -- for example in adolescents -- the pulpotomy is performed as part of an apexogenesis procedure, allowing continued root development by preserving the living pulp in the root canals. More recent studies indicate that in adults with mature roots, a partial or complete pulpotomy may also serve as a viable alternative to conventional root canal treatment in selected cases.

Materials Used

The choice of capping material is critical to the success of the treatment. Commonly used materials include:

Mineral Trioxide Aggregate (MTA): Currently considered the gold standard. It is biocompatible, promotes hard tissue formation, and provides a reliable seal.
Calcium hydroxide: A traditional material with good antibacterial properties, but higher long-term failure rates compared to MTA.
Bioceramics (e.g., Biodentine): Modern alternatives with good biocompatibility and ease of use.
Formocresol: Once widely used, but now less common due to concerns about potential toxic effects.

Risks and Possible Complications

A pulpotomy is generally a safe procedure, but complications may occasionally occur:

Progression of infection if the remaining pulp tissue was already too severely damaged
Internal or external root resorption
Failure of the medicament seal, requiring a full root canal treatment
Post-operative pain or swelling

Prognosis and Success Rates

The success rate of a pulpotomy depends on several factors: the material used, the extent of pulp inflammation, the quality of the seal, and the final restoration. For primary teeth, success rates above 90% have been reported when MTA is used. For permanent teeth, recent studies also show promising long-term outcomes.
