What is PDL space widening?
Malignant lesions are known to quickly grow downward into the periodontal ligament (PDL) space, resulting in an irregular widening and destruction of the lamina dura. Often, root fractures can result in a similar radiographic appearance of the surrounding periodontium.
What causes the PDL to widen?
PDL Widening: Widening of the PDL results from incipient pulpal death and expression of the exudates from the canal space into the surrounding tissues. Long- term degeneration leads to pain, swelling and diffuse infection.
What is the width of PDL space?
The normal width of the PDL ranges from 0.15 mm to 0.21 mm, which may decrease with age. 1,4 Widening of the PDL is one of the most important changes in the circumdental structures and may be related to different abnormalities.
What is periodontal space?
Periodontal Ligament Space Because the PDL is composed primarily of collagen, it appears as a radiolucent space between the tooth root and the lamina dura.
What other conditions can present with a widened PDL space?
Conditions associated with widening are varied and can include:
- trauma. occlusal trauma.
- periodontal disease. periodontitis.
- pulpal / periapical lesions.
- regional osteomyelitis.
- regional tumors / tumor infiltration (rare)
- connective tissue disease.
- radiation-related injury.
- medication-related osteonecrosis of the jaw.
What is PDL dental?
The periodontal ligament, which is often abbreviated as the PDL, is a group of specialized connective tissue fibers that attach the tooth to the alveolar bone. The PDL inserts into root cementum on one side and onto alveolar bone on the other.
Can tooth ligaments heal?
Sprained teeth ligaments can take some time to heal. This is because it’s difficult to not use your teeth. You use and further strain your teeth by chewing, speaking, and swallowing. Further strain to bruised teeth can worsen pain symptoms.
What are the principal Fibres of PDL?
The PDL consists of principal fibers, loose connective tissue, blast and clast cells, oxytalan fibers and Cell Rest of Malassez. The primary principal fiber group is the alveolodental ligament, which consists of five different fiber subgroups.
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.
What is the most reliable indicator of periodontal disease?
While tooth loss is a reliable indicator of gum disease, patients can benefit from advanced periodontal services when they exhibit milder symptoms as well.
Which bony structure is initially destroyed by periodontitis?
The most characteristic feature of periodontitis is the activation of osteoclastogenesis and the destruction of alveolar bone as its consequence, which is irreversible and leads to loss of tooth support.
What is apical Rarefying osteitis?
Apical rarefying osteitis is a radiolucent lesion associated with a periapical inflammatory lesion. Although such lesions may present with non–well-defined borders and lack of cortication, the borders are not infiltrative, and adjacent bone destruction usually is absent.
What are the causes of widening of the PDL?
This review revealed that widening of the PDL might be due to 10 relatively common entities, which could be categorized into 4 groups: traumatic, infectious, neoplas- tic, or systemic causes. Traumatic causes of PDL widening are occlusal/ortho- dontic trauma and radiation-induced bone defect.
What is the radiographic appearance of the PDL?
PDL SPACE RADIOGRAPHIC APPEARANCE • Thin radiolucent line interposed between the root & laminadura. • Occlusal Trauma → widened PDL space or funneling of coronal aspect of PDL space. • It can also widened in case of vertical fractures & progressive systemic sclerosis (Scleroderma).
How to find studies on periodontal ligament widening?
Materials and Methods: An electronic search was performed using specialized databases such as Google Scholar, PubMed, PubMed Central, Science Direct, and Scopus to find relevant studies by using keywords such as “periodontium”, “periodontal ligament”, “periodontal ligament space”, “widened periodontal ligament”, and “periodontal ligament widening”.
Can a widened PDL be a sign of chondrosarcoma?
In tooth-bearing areas, a widened PDL (a Garrington sign) may be noticed as an early sign of chondrosarcoma.28 If the lesion occurs near the teeth, tooth displacement and root resorption may also be seen.4
