Study Notes
Dentin Structure
- Dentin is a calcified tissue that makes up most of the tooth structure
- It is composed of dentinal tubules, which are tiny tubes that transmit sensation to the pulp
Dental Pulp
- The pulp chamber is a hollow space within the center of the tooth that contains the dental pulp
- The main function of the dental pulp is to produce dentin and provide sensation to the tooth
- The apical foramen is a small opening at the apex of the tooth root that allows nerves and blood vessels to enter the pulp chamber
- The function of the apical foramen is to provide a pathway for nerves and blood vessels to enter the tooth
