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?
