    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
