What is radiation fibrosis syndrome?

Radiation fibrosis syndrome (RFS) is a progressive fibrotic tissue sclerosis with various clinical symptoms in the irradiation field. It is usually a late complication of radiation therapy and may occur weeks or even years after treatment.

What are the types of dental caries?

What are the three types of dental cavities?

Occlusal or Smooth-Surface Cavities. An occlusal cavity has only affected the enamel.
Pit and Fissure Cavity. Pit and fissure cavities affect the deep grooves on your molars.
Root Cavity.

What are the symptoms of radiation fibrosis?

Symptoms in patients with GI damage include pain, blood loss, diarrhea, fecal incontinence and changes to bowel movements. In addition, lung tissue in often damaged following radiation therapy.

How do you know if you have osteoradionecrosis?

A sore in the mouth or on the jaw. Trismus, or difficulty opening the mouth. Development of a fistula, or opening, between the jaw and the surface of the face or neck. Decreased or total loss of feeling in the mouth, jaw or lip.

What does osteoradionecrosis look like?

Patients develop an ulcer on the gum, with hard gray/white tissue seen in the depth of the ulcer. The ulcer is often associated with pain and swelling. Sometimes patients will notice that spicules of dead bone are shed from the ulcer.

Can you reverse radiation fibrosis?

Radiation fibrosis can be long-lasting, and though it may not be possible to completely cure it, there are many treatment options which can improve symptoms and reverse some of the changes. Newer radiation treatment strategies can minimize the risk that radiation-fibrosis develops at all.

What is rampant caries?

Rampant caries is a suddenly appearing, rapidly burrowing type of caries resulting in early pulp involvement, in which more than 10 new lesions appear every year on healthy teeth surfaces which are generally immune to caries.[1]

How common is radiation-induced fibrosis?

The commonly reported incidence of radiation-induced fibrosis (RIF) is 10–15% [10], although 23% has been reported [11]. Manifestations of RIF in the breast may result in pain and cosmetic deformities.

Which characteristic is most frequently associated with osteoradionecrosis?

However, it is most commonly characterized by the exposure of the affected bone, in addition to oral ulcers, drainage of purulent secretion and oral fistulas. Pain, foul odor, discomfort in masticatory, swallowing, and speech difficulties are the most common complications.

What happens if osteoradionecrosis is not treated?

This process may be spontaneous or result from trauma, leading to non-healing soft tissue and bone lesions, followed by bone necrosis. The non-healing bone may become secondarily infected.

Is radiation fibrosis permanent?

Radiation-induced fibrosis (RIF) is most often considered to be an irreversible process involving nonspecific changes in the connective tissue and has been associated with extracellular matrix deposition and hyperactive fibroblasts.

What are the long term side effects of radiation?

Radiation to the brain can also have side effects that show up later – usually from 6 months to many years after treatment ends. These delayed effects can include serious problems such as memory loss, stroke-like symptoms, and poor brain function.

What is the characteristic feature of rampant caries?

The distinguishing features of rampant caries are: (1) many teeth are involved; (2) lesion development is rapid; and (3) carious lesions occur on surfaces generally considered to be at low risk to decay, such as proximal surfaces of mandibular ante- rior teeth, facial surfaces of maxillary anterior teeth, and lingual …

Is rampant caries is acute?

Rampant caries has been described by Winter et al’ as a lesion of acute onset involving many or all of the erupted teeth, rapidly destroying corona! tissue, often on surfaees normally immune to decay, and leading to early involvement of the dental pulp.

What is the pathophysiology of caries?

Dental caries are an infectious, communicable disease resulting in destruction of tooth structure by acid-forming bacteria found in dental plaque, an intraoral biofilm, in the presence of sugar. The etiology of rampant disease is very complex.

What causes constant vertigo and loss of hearing?

A viral infection of the vestibular nerve, called vestibular neuritis, can cause intense, constant vertigo. If you also have sudden hearing loss, you may have labyrinthitis. Meniere’s disease. This disease involves the excessive buildup of fluid in your inner ear.

What is the difference between caries and rampant caries?

The bacteria in plaque on your teeth and gums produce acids that attack tooth enamel. “Rampant caries” is a condition characterized by wide-spread and rapidly growing cavities and is a term used to describe a mouth with dental caries present in more than ten teeth.
