What does widening of PDL space mean?

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 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 you regenerate PDL?

Early observations indicated that the PDL has a regenerative capacity and that a population of multipotent progenitor cells may exist within this tissue [36]. Transplantation of PDL-derived cells has shown the potential to regenerate bone and periodontal attachment apparatus in vivo [37–39].

Can a widened PDL be a sign of malignancy?

A purely osteolytic lesion demonstrates a radiolucency with “moth-eaten” or irregular borders that seem to infiltrate into the surrounding bone. Early-stage osteosarcoma of the jaw can also appear as symmetric widening of the PDL space. Therefore, when there is suspicion, biopsy should be performed to rule out malignancy.

What causes a widening of the PDL space?

A purely osteolytic lesion demonstrates a radiolucency with “moth-eaten” or irregular borders that seem to infiltrate into the surrounding bone. Early-stage osteosarcoma of the jaw can also appear as symmetric widening of the PDL space.

What is the radiographic width of the PDL?

Radiographically, the PDL is seen as a radiolucent space between the lamina dura and the tooth root. The nor- mal width of the PDL ranges from 0.15 mm to 0.21 mm, which may decrease with age.1,4Widening of the PDL is one of the most important changes in the circumdental structures and may be related to different abnormalities.5

When do you need 12 weeks of PDL in California?

• In addition to PDL, the California Family Rights Act (CFRA) requires employers of five or more employees to provide 12 weeks of job-protected leave to employees to bond with a new child (by birth, adoption, or foster placement), to care for a family member with a serious health condition, or because the employee has a serious health condition.
