In mandible than maxilla
premolar and molar areas
27
Idiopathic osteosclerosis or DBI

What is a complex odontoma?
Nondescript and heterogeneous mass of dental hard tissue
44

50
What is fibrous dysplasia?
Altered bone metabolism
Cancellous bone is replaced by fibrous CT containing varying amounts of immature, abnormal bone
51
Is fibrous dysplasia uni/multilateral?
Unilateral
52
When does fibrous dysplasia become static?
When skeletal growth ceases
53
When do fibrous dysplasia lesions become active?
During pregnancy or with use of oral contraceptives
May have unilateral face swellings

62
Can Fibrous dysplasia displace teeth?
Yes and can interfere with normal eruption
- can also superiorly displace inferior alveolar nerve
