Periodontal ligament
Periodontal Ligament
The Periodontal Ligament (pronunciation: /ˌpɛriəˈdɒntəl ˈlɪgəmənt/) is a specialized connective tissue that attaches the cementum of a tooth to the alveolar bone. This tissue helps in the functioning and stability of teeth.
Etymology
The term "Periodontal" is derived from the Greek words "peri," meaning around, and "odont," meaning tooth. "Ligament" comes from the Latin word "ligamentum," which means band or tie. Thus, the term "Periodontal Ligament" refers to the band or tie around the tooth.
Function
The primary function of the Periodontal Ligament is to attach the tooth to the bone and hold it in place. It also serves as a shock absorber during chewing and biting, protecting the tooth from excessive forces.
