CEMENTOENAMEL JUNCTIONS Meaning and
Definition
-
Cementoenamel junctions (CEJs), also known as the cementoenamel junction or the cervicoenamel junction, refers to the anatomical connection between the cementum and enamel of a tooth. It is the area where the root cementum meets the enamel that covers the crown of the tooth.
The cementoenamel junction is located at the neck of the tooth, near the gum line. It acts as a protective barrier, sealing the vulnerable dentin layer of the tooth root from bacterial invasion and external stimuli. The cementum is a thin layer of hard connective tissue that covers the root surface, providing attachment for the tooth to the surrounding bone through the periodontal ligament. On the other hand, the enamel is the hard, outermost layer of a tooth that forms the crown and protects the dentin.
The cementoenamel junctions can vary in shape, depth, and location. They can be straight or slightly curved, depending on the tooth type and individual variations. They are commonly used as reference points in dental examinations, periodontal measurements, and dental treatments such as restoration placement or gum surgery.
The cementoenamel junctions play a crucial role in maintaining the stability and integrity of the tooth structure. Any abnormalities or irregularities in this junction can affect the health of the tooth, leading to various dental issues such as tooth sensitivity, gum recession, or root caries. Thus, understanding and evaluating the cementoenamel junctions are important for dental professionals to provide proper diagnoses, treatments, and preventive care.

Etymology of CEMENTOENAMEL JUNCTIONS
The term "Cementoenamel Junctions" is a combination of three words: cementum, enamel, and junctions.
1. Cementum: The word "cementum" derives from the Latin word "cementum", which means "stone, cement". In dental anatomy, cementum refers to the calcified connective tissue that covers the root of the tooth, providing support and attachment for the periodontal ligament.
2. Enamel: The word "enamel" comes from the Old French word "esmail", which originated from the Greek word "smegma" meaning "to smear" or "to polish". Enamel is the hard, outermost layer of the tooth characterized by its high mineral content, which protects the underlying dentin.
3. Junctions: The term "junctions" is derived from the Latin word "junctio", meaning "joining" or "connection".
