What are the diseases of pulp and periapical tissues?

Endodontic disease is defined as disease affecting the pulp and periapical tissues of the tooth. Once within the pulpal tissues, bacteria cause infection and ultimately necrosis of pulp.

What are periapical diseases?

Periapical disease refers to pathology around the. apex of a tooth root or roots. This will be taken to. infer the disease to be inflammatory, usually as. a result of pulp necrosis.

WHO classification periapical lesions?

The World Health Organization (33) has classified apical periodontitis in five categories: Acute apical periodontitis of pulpal origin Chronic apical periodontitis of pulpal origin Periapical abscess with sinus Periapical abscess without sinus Radicular cysts.

What does periradicular periodontitis mean?

Periapical periodontitis (also termed apical periodontitis, AP, or periradicular periodontitis) is an acute or chronic inflammatory lesion around the apex of a tooth root which is usually caused by bacterial invasion of the pulp of the tooth.

What is periradicular tissue?

• Periradicular tissue consists of root cementum,periodontal ligament and the alveolar bone. The apical periodontium is. highly cellular structure enriched with blood and lymphatics as well as sensory and motor nerve fiber supplying both. pulp and periodontium.Periradicular pathology are mostly of pulpal orgin.

Is periapical and periradicular the same?

(C) A radiograph of mandibular right second molar that exhibits, based on location, a “periapical” lesion or radiolucency at the apex of the mesial and distal roots. Some clinicians may describe this as a “periradicular” lesion because of its extensive encompassing of the root structure.

What causes periapical disease?

Periapical periodontitis is a chronic inflammatory disease, caused by endodontic infection, and its development is regulated by the host immune/inflammatory response.

What means periapical lesion?

Periapical lesions (PLs) are among the most frequently occurring pathological lesions of the alveolar bone. 1-3. They occur in relation to the tissues around the apex of a tooth root, the periodontal membrane and the alveolar bone.

Where is the Periradicular area?

around a root, such as the root of a tooth.

What are the different types of periodontal disease?

Types of Periodontal Disease

• Types of Periodontal Disease.
• Gingivitis.
• Chronic Periodontal Disease.
• Aggressive Periodontal Disease.
• Periodontal Disease Relating to Systemic Conditions.
• Necrotizing Periodontal Disease.

What are the stages of periodontal disease?

Periodontitis is broken down into four stages:

• Periodontitis Stage 1: Initial.
• Periodontitis Stage 2: Moderate.
• Periodontitis Stage 3: Severe with potential for tooth loss.
• Periodontitis Stage 4: Severe with potential for loss of all the teeth.

What causes periapical granuloma?

It is a lesion or mass that typically starts out as an epithelial lined cyst, and undergoes an inward curvature that results in inflammation of granulation tissue at the root tips of a dead tooth. This is usually due to dental caries or a bacterial infection of the dental pulp.

What is periapical granuloma?

Periapical granuloma is one of the most common of all sequelae of pulpitis. It is essentially a localised mass of chronic granulation tissue formed in response to the infection. The involved tooth is sensitive to percussion, and the patient feels pain while chewing solid food.

Is periapical and Periradicular the same?

What are the different types of periradicular diseases?

1. PERIAPICAL DISEASES 2. CLASSIFICATION Symptomatic periradicular diseases a)symptomatic apical periodontitis i) vital tooth ii) non vital tooth b)Acute alveolar abscess c)Phoenix abscess External root resorption Persistent apical periodontitis 3.

What causes destruction of the periradicular tissue?

However, with an excessive amount of irritants or persistent exposure, the nonspecific and specific immunologic reactions can cause destruction of periradicular tissues.  In addition to bacterial irritation, the periradicular tissues can be mechanically irritated and inflamed.

Do pathologic changes in the pulp cause periradicular lesions?

Introduction  As a consequence of pathologic changes in the dental pulp,may or may not initiate formation and perpetuation of periradicular lesions. Depending on the nature and quantity of irritants,as well as the duration of exposure of the periradicular tissues, a variety of tissue changes can occur.

What causes periradicular inflammation?
