Caries in primary teeth spreads rapidly and often reaches the pulp of the tooth. The pulp must be treated by removing caries and covering the pulp to preserve its vitality, and then to preserve the health of the tooth and its supporting tissues.[9]
Treatment options include:
Indirect endodontic coverage.
Direct endodontic coverage.
pulpotomy.
Endodontic treatment by excision.
Indirect endodontic coverage: It is a technique used to preserve the vitality of the dental pulp by covering the thin dentin layer that coats the pulp with restorative dental materials such as calcium hydroxide.[10]
Direct pulp coverage: This technique is used when perforating the dentin layer with a distance of one mm, and accidentally exposing the tooth pulp during the caries removal process, but it is not used to treat pulp caries in milk teeth due to its weak effectiveness, and the exposed pulp is covered with calcium hydroxide or total metal trioxide ( MTA).[10]
Pulpotomy: It is the process of removing the coronal part of the pulp of the milk tooth without including the root part, then treating the remaining part with dental materials such as formocresol or total metal trioxide (MTA) and ferric sulfate, in addition to sodium hypochlorite, calcium hydroxide and calcium silicate, but to a lesser extent. [10] ]
Endodontic treatment by excision: It is the process of treating pulpitis after tooth decay reaching the pulp by removing the pulp, including the root part. The pulp is removed with its coronal and root parts, the pulp canals are filled with dental material, and finally the dental filling is placed. The dental materials used must be soluble with the root of the tooth to prevent any problems associated with the process of replacing milk teeth with permanent teeth.[9]
