Which material is most commonly used for primary tooth pulpotomy?

Formocresol has been widely used as the material of choice for primary tooth pulpotomy due to its effectiveness in preserving pulp vitality and promoting favorable outcomes in the treatment of carious pulp exposures. It is a phenolic compound that acts as a bactericide and has the ability to fix pulp tissue, thus helping to prevent further bacterial contamination and facilitating healing. Its properties allow for a relatively straightforward procedure, making it suitable for pediatric dentistry where managing anxiety and ensuring cooperation from young patients are pivotal.

The other materials listed, while they have their own benefits and applications in dentistry, do not have the same historical level of widespread use for pulpotomies in primary teeth. For instance, calcium hydroxide serves primarily as a pulp capping agent and is not always as effective as formocresol in pulp therapy for primary teeth due to its tendency to cause more inflammatory responses. Mineral trioxide aggregate is a suitable material for more complex cases and permanent teeth due to its biocompatibility and sealing abilities, but it is not as commonly used in primary tooth pulpotomies. Blood plasma concentrate is an innovative approach in regenerative therapies but has not been established as a standard method for pulpotomy in primary teeth.

Thus, formocresol
