The structure of PDL
becomes more irregular with increasing age
26 – 28
. With advancing age, degenerating hyaline changes can be observed in PDL. Calcified bodies can also be observed in PDL and the epithelial rests show altered aggregation.
What causes widening of the PDL?
PDL widening occurs in
trauma from occlusion
, but in association with angular bone defects and mobility of teeth. However, in scleroderma, involved teeth are often not mobile and their gingival attachments are usually intact.
Can PDL be regenerated?
The regeneration of PDL is an important requirement for
periodontal regeneration
. The ideal outcome would be that the regenerated highly-organized collagen fibers could re-insert perpendicularly and firmly attached to the regenerated cementum and new bone [58].
What are the age changes in periodontium?
Research findings do suggest that the
degree of periodontal breakdown increases with age
, that with increasing age inflammation of the periodontium tends to develop more rapidly and that in the process of aging the periodontium shows a slower rate of wound healing.
Why does Keratinization of gingiva decrease with age?
Oral mucosa becomes thin, smooth and dry with advancing age. Gingiva is composed histologically by epithelium and connective tissue. Changes in epithelium caused by aging are atrophy (thinning of epithelium), diminished keratinization and modification of junction between epithelium and connective tissue [12].
Does periodontal ligament grow back?
The periodontal ligament does not regenerate easily in any areas where it was lost
and is prone to periodontal inflammation. Should a patient’s advanced gum disease have damaged the jawbone, placing a bone graft may be unsuccessful if the periodontal ligament is not also simultaneously restored.
Can periodontal ligaments regrow?
The periodontal ligament does not regenerate easily in any areas where it was lost
and is prone to periodontal inflammation. Should a patient’s advanced gum disease have damaged the jawbone, placing a bone graft may be unsuccessful if the periodontal ligament is not also simultaneously restored.
What are the stages of gingivitis?
Periodontal disease is broken up into four separate stages:
gingivitis, slight periodontal disease, moderate periodontal disease
, and advanced periodontal disease. Gingivitis is the only stage of periodontal disease that is reversible as it has not yet had time to attack the bones.
What does PDL stand for in dentistry?
The
periodontal ligament
, commonly known as the PDL, is a soft connective tissue between the inner wall of the alveolar socket and the roots of the teeth. It consists of collagen bands (mostly type I collagen) connecting the cementum of teeth to the gingivae and alveolar bone.
What structures make up the Periodontium?
The periodontium is a connective tissue consisting of four components:
cementum, the periodontal ligament (PDL), alveolar bone, and gingival tissue
.
Why stippling is present in gingiva?
Stippling occurs as
a result of the microscopic elevations and depressions of the surface of the gingival tissue due to the connective tissue projections within the tissue
. … It corresponds to the fusion of the valleys created by the connective tissue papillae.
What is junctional epithelium?
The junctional epithelium (JE) is
an epithelial component that is directly attached to the tooth surface
and has a protective function against periodontal diseases.
Does periodontal disease ever go away?
Periodontal disease (infection of the gum tissue and bones surrounding teeth) is an
increasing health risk which will not go away by itself
, but requires professional treatment.
Should the periodontal ligament be removed?
When you bite down and chew, the PDL protects the tooth from shattering by compressing a fraction of a millimeter like a spring. It is standard of care for a traditional oral surgeon to assume that the periodontal ligament adheres to the tooth and
is therefore always removed during an extraction
.
What does periodontal ligament pain feel like?
Dentists specifically look for
dull or achy pain
as indication of a ligament sprain
How do you get rid of periodontal ligaments?
Once the tooth is removed, the periodontal ligament and potentially up to one millimeter of spongy bone in the socket is removed via a
#8 or #10 long-shanked surgical round bur
.
