The Dentinoenamel Junction The dentinoenamel junction (DEJ) is a critical area in our teeth that connects dentin and enamel. Understanding this junction is key to appreciating how our teeth develop and maintain their health. This article breaks down what the DEJ is, its role in dental health, common problems that can arise, and the latest research on this important topic. … [Read more...] about Dentinoenamel Junction In Dental Health

Dentinal Sensitivity Theories of dentinal sensitivity: Direct nerve innervations theory "What is dentinal sensitivity? A detailed question and answers guide" Direct nerve innervations theory states that the dentin contains nerve endings that respond when it is stimulated.
