What cells from the pulp cavity continue to manufacture dentin throughout the life of a tooth?
Correct Answer
OdontoblastsExplanation
Odontoblasts are cells found in the pulp cavity of a tooth that continue to manufacture dentin throughout the life of the tooth. Dentin is a hard, mineralized tissue that makes up the majority of the tooth structure. Odontoblasts are responsible for the production of dentin, which helps to protect the underlying pulp and maintain the structural integrity of the tooth. As the tooth ages and undergoes wear and tear, odontoblasts continuously produce dentin to repair and strengthen the tooth. This ongoing dentin production by odontoblasts ensures the longevity and functionality of the tooth throughout a person's life.Rate this question:
