3. Types
• True generalised – all the teeth are larger than
normal. It is commonly associated with
pituitary gigantism
• Related generalised – teeth are normal or
slightly larger than normal, but present in a
smaller jaw
• Localised – one or more large teeth exist in
relation to an otherwise normal dentition and
body size
4. Causes
• Facial hemihypertrophy – it is occasionally
seen in facial hemihypertrophy, in which half
of the teeth in unilateral distribution are
affected
• gigantism-in this generalised overgrowth of
the body occurs
• Genetic – genetic component also responsible
for macrodontia
5. Clinical features
• Teeth size – teeth are larger than normal
• Malocclusion – there is crowding, which may
result in malocclusion
• Impaction – as space is less, there is impaction
of teeth
