What is the difference between free and attached gingiva?
Attached gingiva – This tissue is adjacent to the free gingiva and is keratinized and firmly attached to the bone structure. It can range from 3-12 mm in height. Free gingiva – This tissue is not attached and forms a collar around the tooth.
What is marginal gingiva?
The terminal edge of gingiva (gums) that surrounds the teeth is known as the gingival margin (marginal gingiva). The gingival margin lacks the presence of stippling and the tissue is mobile or not attached to the surface of the underlying tooth.
What is the purpose of free gingiva?
The free gingival margin is located in the oral cavity and is a term used to describe the interface between the sulcular epithelium and the epithelium. This specific interface is present at the most coronal point of the gingiva. This is also referred to as the crest of the marginal gingiva.
Is marginal gingiva attached?
It is lined with sulcular epithelium and attached to the tooth at its base by the epithelial attachment. Gingival margin – The border region of the gingiva that touches the tooth.
Why is attached gingiva important?
Historically, the presence of a wide zone of attached gingiva has been considered beneficial, as the gingiva plays an important role in maintaining the periodontium in health. It provides a physical barrier to oral biofilm, dissipates masticatory forces and protects the periodontium from injury.
Why attached gingiva is keratinized?
Anatomically gingiva is divided into: Free Attached and Interdental gingiva. 4. Attached gingiva is a part of keratinized gingiva which aids in Increase resistance to external injury and contribute in stabilization of gingival margin. Against frictional forces.
Is marginal gingiva free gingiva?
The free gingival margin is the area located between the sulcular epithelium and the epithelium of the oral cavity. This interface exists at the most coronal point of the gingiva, which is also known as the crest of the marginal gingiva. The gingival margin (F) is the most coronal point of the gingiva.
What is free gingival groove?
The free gingival groove is defined as a shallow V-shaped groove. which runs parallel to the margin of the gingiva at a distance of 0.5-1.5 mm. (Orban 1948). It is thought to develop at the level of, or somewhat apical to. the top of the epithelial attachment due to functional impacts on the free.
Is marginal and free gingiva the same?
Is free gingiva the same as marginal gingiva?
What demarcates the free gingiva from the attached gingiva?
A shallow linear depression, the gingival groove, can be observed in some areas, distinguishing the free gingival margin from the attached gingiva. Microscopically, gingiva consists of stratified squamous epithelium supported by a thin layer of dense fibrous connective tissue (Box 2.4).
Is free gingiva keratinized?
Dental anatomy Most of the gingiva is firmly attached to the supporting bone, with a slightly more mobile (usually non-keratinized) area, termed the free (marginal) gingiva, which is the prominent area close to the tooth.
