Oral Manifestations Of Systemic Disease Flashcards
What are the two ways of making a diagnosis?
What we see and hear
Medical history and examination
Extra oral examination
Extra oral examination inside mouth
How do teeth indicate systemic disease ? Abnormal colour
Tetracycline = yellow to brown or grey
Fluorosis = opaque white or brown patches
Severe / childhood jaundice = yellow or green
Porphyria = (rare hereditary disease of haemoglobin metabolism) purplish red
Dentinogenesis Imperfecta / Osteogenesis Imperfecta = purplish or brownish but INCREASED TRANSLUCENCY
What can cause Dental Hypoplasia?
(Underdevelopment)
(5)
- Congenital syphilis
- Severe childhood fevers
- Severe fluorosis
- Severe rickets
- Hypoparathyroidism
Congenital syphilis - dental hypoplasia?
– Notched and peg-shaped permanent incisors
– Molars may also be deformed (Moon’s molars)
Severe childhood fevers - dental hypoplasia?
– Horizontal grooves or pits
– particularly of the incisors
Severe fluorosis - dental hypoplasia?
– Rough pitting, white / brown
– opacities (very high fluoride areas
– eg Yemen / Sudan etc)
Severe rickets - dental hypoplasia?
– Grooving or pitting of the enamel
Hypoparathyroidism - dental hypoplasia?
– Ectodermal defects
– (grooving / pitting of enamel)
What causes abnormal loss of tooth surfaces?
1) Erosion - Extrinsic acids – (diet)?
Intrinsic acid – (gastric)?
– risk of oesophageal metaplasia and malignant conversion
– Typical in reflux disease
– heartburn
– Bulimia nervosa… (look for calloses on dorsum of digits)
2) Attrition - bruxism / TMJD / general emotional wellbeing?
3) Abrasion - components of diet / other device intra orally eg mouthpiece of wind instrument etc?
Look at reflective qs from PowerPoint 1
How does colour of mucous membranes indicate systemic disease?
Anaemia
Anaemia = pallor of mucus membrane + red beefy sore tongue
How does colour of mucous membranes indicate systemic disease?
Pigmentation
Ethnicity
Addisons disease
How does colour of mucous membranes indicate systemic disease?
Blue due to cyanosis
Cardiovascular disease
Respiratory disease
How does colour of mucous membranes indicate systemic disease?
Yellow tint due to jaundice?
haemolytic
obstructive hepatic
infectious
How does colour of mucous membranes indicate systemic disease?
White due to keratosis
trauma
mucosal disease
candida
cancer
How does colour of mucous membranes indicate systemic disease?
Blue / brown gingival margins
Heavy metal poisoning - lead and bismuth
How does colour of mucous membranes indicate systemic disease?
Blue / Brown patch
– melanoma
– Amalgam tatoo
– Silver sulphide – old silver point RCT
How does gingival / mucosal bleeding indicate systemic disease?
PURPURA (bleeding under skin)
- HIV/AIDS + acute leukaemias
- iatrogenic - steroids
- Myelodysplasias
- excessive gingival bleeding
DISORDERS OF CLOTTING
- anticoagulant excess
- purpura not present
- HAEMOPHILIA A is the most important cause
- von willebrand disease
- excessive gingival bleeding
EXCESSIVE GINGIVAL BLEEDING
Main causes of acute gingivitis
– Acute leukaemia,
– immunodeficiencies,
– AIDS
– Agranulocytosis
– Uncontrolled diabetes
- vitamin deficiencies - vit C - scurvy, vit B3 - pellagra
What causes gingival hyperplasia?
– Nifedipine
– Cyclosporin
– Phenytoin
Consider leukaemia
Link between stomatitis - ulceration and systemic disease
What might cause the ulcers?
Apthous Ulceration because of :
- Recurrent aphthous stomatitis
- low levels of iron, folate and B12 (haematological associations)
- diet
- GI malabsorption / metabolic issues
Beçhet’s Disease
More than three episodes of oral ulcers per year
Reactive arthritis
Drug therapies
• Cardiovascular – Beta-blockers, niocorandil
• Oral hypoglycaemics (DM2)
• Chemotherapy cytotoxics
• Sulphonamides
• Barbiturates,
• Gold
• Urea
Examples of systemic infections that affect mucous membranes - cause stomatitis
Stomatitis (inflammation of mucous membrane in the mouth)
Measles
Chicken pox
Syphilis
Herpes zoster
Herpes simplex
Tuberculosis - hiding painful ulcer
Actinomycoses – Occasionally following removal of wisdom teeth,
– fistula forms, yellow sulphur granules
