Oral Surgery Flashcards
inflammation of tissues surrounding the teeth
gingivitis
inflammation surrounding teeth causing loss of bone
periodontitis
what is a cavity/how is it formed?
bacteria colonize tooth → metabolize sugars → acid left erodes tooth
what is dry socket?
After tooth extraction, a blood clot forms and will eventually be replaced by granulation tissue and bone.
aggressive and rapidly spreading cellulitis that involves the bilateral sublingual, submandibular, and submental spaces
ludwig’s angina
**this is a surgical emergency
exostosis that occurs on the posterior aspect of lingual aspect of mandible
torus mandibularis
exostosis that occurs in the palate.
torus palatinus
what is hairy tongue due to?
poor hygiene and smoking leads to accumulation of keratin on filiform papillae on dorsal of tongue
Hairy leukoplakia is assc with ____ and is found typically on what part of the tongue
HIV and EBV
lateral
Areas of erythema surrounded by elevated yellow scalloped borders
erythema migrans or geographic tongue
pathophys of aphthous ulcers
T cell mediated destruction of the mucosa of the tongue
white patch or plaque that cannot be characterized clinically or pathologically as any other disease
leukoplakia
lesion on the tongue that can be dysplastic and proceed carcinoma
leukoplakia
what are the inflammatory cysts and the developmental cysts
inflamm: periapical and residual
developmental: dentigenerous and odontogenic
what are odontogenic cysts?
epithelium lined cyst derived from odontogenic
cyst that originates by the separation of the follicle from around the crown of an unerupted tooth
dentigenerous cysts
most aggressive and recurrent of all odontogenic cysts and resemble both cyst and tumor
Odtongenic keratocyst (OKC)
Slow growing locally invasive tumors that run a benign course in most cases. Tumor of odontongic epithelium
odontogenic tumors
cyst assc with wisdom teeth (i.e. one of the reasons they are taken out)
dentigerous cysts
ADE with bisphosponate therapy
necrosis of the jaw
MOA BRONJ
Decrease bone turnover by inhibiting bone resorption by osteoclasts.
• Inhibit osteoclast recruitment
• Diminish osteoclast life span
• Inhibit osteoclast activity at the bone surface
assc with basal cell nevus syndrome
Odtongenic keratocyst (OKC)
It is a low grade variant of oral squamous cell carcinoma–Commonly arise in people who chronically use chewing tobacco or snuff
Verrucous carcinoma
carcinoma of lower lip is more likely to be …
carcinoma of upper lip is more likely to be …
Lower = SCC Upper = basal
cyst lined by stratified parakeratinized squamous epithelium that lacks rete ridges. Basal cells are hyperchromatic and cuboidal to columnar in shape with palisaded nuclei
Odtongenic keratocyst (OKC)
SUMMARY:
The most common significant odontogenic tumor is the…
ameloblastoma
SUMMARY:
The most common significant odontogenic cyst is the…
OKC
SUMMARY:
aggressive dental infection
Ludwig’s angina
SUMMARY:
what spaces are swollen in Ludwig’s angina. significance?
BL submental/submandibular/sublin gual swelling)
airway protection
SUMMARY:
can cause large mandibular/maxillary expansion and are treated with resection
amelobastoma and OKC
SUMMARY:
synergistic in causing HNSCC
tobacco and alcohol use
SUMMARY:
causing an increase in HNSCC in a young males
HPV
SUMMARY:
major predictor in long term survival in HNSCC
LN mets
SUMMARY:
IV or oral bisphosponates have a greater risk for BRONJ
IV
SUMMARY:
Upper lip cancer frequently
BCC
SUMMARY:
Lower lip cancer frequently
SCC
