Periodontitis In Permanent Teeth Flashcards
The structure around the root apex is called
Periapical tissue
Periapical tissue made out of
🔸PDL
🔸Alveolar bone
Inflammatory changes around the apex of a tooth due to necrotic pulp
Periapical disease
Inflammatory changes in the periapical space
Apical periodontitis
Periodontitis can be
🔸Apical
🔸Gingival
In case of incomplete root development, the Periapical structure is composed only of
🔸Growth zone
🔸Periapical bone
In case of incomplete root development, the periodontium is missing due to
Lack of apex
In case of incomplete root development, the inflammatory process around the apex is called
Periapical osteitis
Features of permanent teeth with incomplete root development
🔸No periodontium around apex
🔸Wide open root to bone
🔸 only growth zone between pulp and bone
Characteristics of bone around the roots of a tooth with Incomplete development
🔸Bone under development
🔸 Thin bone ridges
🔸Wide interosseous spaces
🔸 Extensive blood supply
Aetiology of periapical diseases
🔸Bacterial infection
🔸Trauma
In periapical lesions, high content of …………. Is present
Aryl sulphatase A and B
Aryl sulphatase A and B play a role in
🔸Pathogenesis of endodontic lesions
🔸Bone degradation
🔸Degrade Chondroitin-4-sulphate
Gram negative microorganisms release ……….. during cell degradation
Endotoxin LPS
Bacterial LPS toxin
🔸Composed of polysaccharides
🔸Has lipid A region responsible for toxicity
