What is Keratinization in gingiva?
The keratinized gingival is the part of the oral mucosa which covers the gingiva and hard palate. It extends from the free gingival margin to the mucogingival junction and consists of the free gingiva as well as the attached gingiva. Such a graft will assist with gum health as well as implant stability.
What are the characteristics of normal gingival tissue?
Healthy gingiva is described as ‘salmon’ or ‘coral pink’. It may be pigmented, which reflects the ethnic origin of the subject. The gingiva is firm in consistency and firmly attached to the underlying alveolar bone. The surface of gingiva is keratinised and may exhibit an orange peel appearance, called ‘stippling’.
How do you describe gingival margin?
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 are the 3 anatomical division of the gingiva?
The underlying alveolar bone provides support to the existing teeth, and its arbitrary inferior border is the root apices of the teeth. It relies on the presence of teeth for its development and the maintenance of bone mass. The gingiva has been traditionally subdivided into free, attached, and interdental gingiva.
What is the Keratinization?
Keratinization is defined as cytoplasmic events that take place in keratinocytes that move through the different layers of the epidermis to finally differentiate into corneocytes.
Why gingiva is firm and resilient?
39. Consistency: The gingiva is firm & resilient with exception of the movable free margin, tightly bound to underlying bone. The collagenous nature of lamina propria & its contiguity with mucoperiosteum of alveolar bone determines the firmness of attached gingiva. Resilient is due to gingival fibers.
What is gingival exudate?
Gingival crevicular fluid is an inflammatory exudate derived from the periodontal tissues. It is composed of serum and locally generated materials such as tissue breakdown products, inflammatory mediators, and antibodies directed against dental plaque bacteria.
Is gingival margin the same as recession?
Gingival recession, also known as receding gums, is the exposure in the roots of the teeth caused by a loss of gum tissue and/or retraction of the gingival margin from the crown of the teeth.
Is gingival margin recession?
Gingival recession occurs when the edge of the gingival tissue (called the gingival margin) moves away from the crown of the tooth. One of the main causes of gingival recession is an irregular or abnormal tooth position.
What Innervates the gingiva?
The innervation of the oral gingiva is unique because all the nerves supplying the gingival mucosa originate from the mandibular and maxillary branches of the trigeminal nerve (CN V).
What is the function of gingival crevicular fluid (GCF) and saliva?
The gingival crevicular fluid (GCF) and saliva play an important role in the defense mechanism of the oral cavity. Both GCF and saliva contain a variety of chemical mediators which serve various functions in the defense mechanism against infections. The composition of these fluids is different in inflammation as compared to periodontal health.
How do you collect cells from the gingival sulcus?
Using a peristaltic pump, the gingival sulcus is irrigated with saline solution for 15 minutes and diluted GCF is collected 28. The collected fluid contains both cells and soluble constituents such as plasma proteins. The main advantage of this technique is that it can be used to harvest cells from the gingival crevice 29.
How long does it take for ink to leave the gingival sulcus?
The ink particles were almost completely eliminated from the gingival sulcus within next 48 hours. The results of this study suggested that fluid is formed in the gingival sulcus, which has a flushing action on the bacteria and debris present in the gingival sulcus.
What are the defense mechanisms of the oral cavity?
Various defense mechanisms active in the oral cavity include saliva, gingival sulcular/crevicular fluid, intact epithelial barrier (junctional epithelium), the presence of beneficial flora, migrating polymorphonuclear cells and other leukocytes, and local antibody production.
