What is dental epithelial attachment?
Epithelial attachment refers to the mechanism of attachment of the junctional epithelium to a tooth or dental implant, i.e., hemidesmosomes. The cells of the epithelium at this attachment point are non-keratinized and form a collar around the tooth around the cemento-enamel junction.
Which type of epithelium is the gingiva composed of?
Microscopically, gingiva consists of stratified squamous epithelium supported by a thin layer of dense fibrous connective tissue (Box 2.4).
What is gingival epithelium?
The gingival epithelium plays an important role as a mechanical barrier against bacterial invasion and a part of the innate immune response to infectious inflammation in periodontal tissue. The disorganization of cell–cell interactions and subsequent inflammation contribute to the initiation of periodontal disease.
What is the attached gingiva attached to?
alveolar bone
What are the two types of gingiva?
There are two types of gingiva and several important anatomic regions.
- Alveolar mucosa – The area of tissue beyond the mucogingival junction.
- Attached gingiva – This tissue is adjacent to the free gingiva and is keratinized and firmly attached to the bone structure.
Why is attached gingiva important?
the gingival sulcus or the periodontal pocket. Functions Of Attached Gingival Gives support to marginal gingiva Help to withstand the functional stresses of mastication & tooth brushing. Provide attachment or a solid base for the movable alveolar mucosa for the action of the cheeks, lips, and tongue.
What is the function of gingiva?
Gingival Structure, Function, and the Latest Research The gingiva (or gums) is the tissue that surrounds and protects the teeth and underlying bone. The gingiva is attached to the tooth, forming a seal that protects the underlying bone and helps provide a barrier against infection.
How is attached gingiva calculated?
Sulcus depth was measured as the distance from the gingival margin to base of the sulcus. With these values, the width of attached gingiva was calculated as a difference of the sulcus depth from the width of the keratinized tissue.
Why does attached gingiva increase with age?
It was concluded that the mucogingival junction remains at a probably genetically predetermined location while the teeth move in an occlusal direction through adult life. In the absence of concurrent retraction of the gingival margin this results in an increase of the width of attached gingiva with advancing age.
Where is the widest area of the attached gingiva?
The attached gingiva is widest in the incisor region (3.5 to 4.5 mm in the maxilla and 3.3 to 3.9 mm in the mandible) and narrowest in the first premolar region (1.9 mm in the maxilla and 1.8 mm in the mandible).
Which tooth has the least amount of attached gingiva?
The percentage of gingival groove The highest percentage of gingival groove on the oral aspect was found in relation to the right upper premolars (31%), and the least was found in the right lower molars (4%).
What is gingival zenith?
The zenith is defined as the most apical point of the gingival marginal scallop. This important landmark was described as having a specific spatial orientation in the apico-coronal and mesiodistal directions.
What is a gummy smile?
A gummy smile is one that shows more of your gumline than you’d prefer. It’s also known as excessive gingival display. A gummy smile can be caused by: the way your teeth grow in. the length of your upper lip.
What is a smile arc?
The smile arc is defined as the relationship of the curvature of the incisal edges of the maxillary incisors and canines to the curvature of the lower lip in the posed smile. The ideal smile arc has the maxillary incisal edge curvature parallel to the curvature of the lower lip.
Should teeth touch when smiling?
When you look at teeth from the front – think of looking at yourself in the mirror – a perfect bite will feature upper front teeth that are lined up parallel to your lower lip when you smile. When you close your bite, about half to two-thirds of the length of your bottom teeth should be easily visible.
How can I improve my smile arc?
Braces or clear aligners in the hands of an experienced orthodontist can improve your smile arc. If you or a loved one needs work on your smile arc, find a credentialed orthodontic specialist * today.
Why are my brackets so low on my teeth?
Brackets may be placed higher or lower on the teeth depending on which direction they need to shift in order to leave you with the most perfect possible smile. Frequently, this means fixing teeth that are crowded or crooked. In some cases, your teeth may be straight, but your upper and lower jaws may not meet properly.
How do orthodontists know where to place brackets?
Braces move teeth into place through a treatment schedule devised by your orthodontist. Orthodontists will place the brackets in exactly the right place on the tooth, then thread an archwire through which will slowly move back to it’s original shape.
Will my teeth look good after braces?
How your teeth will look without braces depends a lot on how well you took care of them with the braces on! It is not uncommon for teeth to have yellow tartar or stains on them that become much more noticeable once the braces are off. A clean mouth also makes the process of getting braces off much easier.
