Why is pulpectomy usually contraindicated in primary first molars?

They have a lot of accessory canals
They are too small
They lack sufficient root structure
They are typically non-vital

The correct answer is: They have a lot of accessory canals

Pulpectomy is a dental procedure that removes the pulp from the inside of a tooth in order to save it from infection or decay. It is usually not recommended for primary first molars, as they have a lot of accessory canals that can make it difficult to fully remove all infected or dead tissue. This increases the chance of an incomplete pulpectomy, which can lead to further infection or complications. Options B, C, and D are incorrect because they do not relate to the main reason for pulpectomy being contraindicated in primary first molars - the presence of accessory canals. These options do not address the technical aspect of the procedure, which is the main concern for avoiding pulpectomy in primary first molars.
