1. Macrodontia

2. General information These are the teeth which are larger than normal

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

6. Radiographic features The increased size will be demonstrated on the radiograph

7. Diagnosis By looking at the size of tooth clinical diagnosis can be made easily

8. Management If necessary orthodontic treatment is done If impacted extraction is indicated
