Describe chronic hyperplastic pulpitis?
The infected pulp comes out the coronal portion because it’s easier to come out that way.
What is the most common periapical pathosis?
Periapical Granuloma
Describe a periapical granuloma?
mass of inflamed granulation tissue at the apex of a non-vital tooth
How does a periapical granuloma present clinically?
asymptomatic: no pain or sensation
What’s the radiographic presentation of a periapical granuloma?
Well defined radiolucency, root resorption, punched out border
Describe radiographic presentation of periapical cyst?
well defined radiolucensy, root resorption, punched out border
What causes a periapical cyst?
inflammation stimulation of epithelium in the area (Rests of Mallasez)
Describe a histologic presentation of a periapical granuloma.
Mixed pink collagen with neutrophils
Describe a histologic presentation of a periodontal cyst?
Spiderweb like-white empty space
Describe a histologic presentation of a periapical abscess.
Lots of neutrophils
What is the main thing noticable about a periapical abscess?
Lots of neutrophils
Describe a periapical scar
Lots of pink collagen tissue
When are periapical scars most commonly going to happen?
After endo treatment
What’s the difference between and intraoral sinus tract and Cutaneous sinus tract?
Intraoral is inside the mouth
Cutaneous sinus tract is outside the mouth
Which teeth do cutaneous sinus tracts most often occur from?
Mandibular
What are two other names for an intraoral sinus tract?
Parulis
Gum boil
What causes a sinus tract?
Pus from a Periapical abscess dissects through the bone, path of least resistance till it drains through the mucosa/skin
What are the two types of Cellulitis?
Ludwigs angina
Cavernous sinus thrombosis
What is Cellulitis?
It’s like a sinus tract, but the pus never finds a clear exit point and it spreads throughout a lot of soft tissue.
What does Ludwigs angina (cellulitis) look like? and what teeth is it from?
“Bull neck” and “woody tongue” swollen neck
Mandibular teeth
What are symptoms of Ludwigs angina?
Pain in the neck
Dysphagia, Dysphonia, Dysarthria
What does cavernous sinus thrombosis look like?
Edematous periorbital enlargement
Swelling along the lateral border of the nose
Which teeth abscesses cause Cavernous Sinus Thrombosis?
Maxillary Anterior/Premolar
What’s the difference in “Condensing Osteitis” and “idiopathic Osteosclerosis”?
Radiographically identical
Condensing Osteitis has inflammation
What is condensing osteitis?
Bone scar at apex
Localized bone sclerosis at the apex
What is it called when you get erosion from gastric acid?
