Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.
Growth arrest lines, also known as Harris lines, are lines of increased bone density that represent the position of the growth plate at the time of insult to the organism and formed on long bones due to growth arrest. They are only visible by radiograph or in cross-section. The age at which the lines were formed can be estimated from a radiograph.
The epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length).
An enostosis is a small area of compact bone within the cancellous bone. [1] [2] They are commonly seen as an incidental finding on radiographs or CT scans. They are typically very small and do not cause any symptoms. [3] Their radiodensity is generally similar to cortical bone. [4] No treatment is necessary. Multiple enostoses are present in ...
Condensing osteitis, also known as focal sclerosing osteomyelitis, is a rare periapical inflammatory condition characterized by the formation of sclerotic bone near the roots of premolars and molars. This condition arises as a response to dental infections, such as periapical pulp inflammation or low-intensity trauma.
Osteopoikilosis is a benign, autosomal dominant, sclerosing (hardening) dysplasia of bone characterized by the presence of numerous bone islands in the skeleton. [ 1 ] Presentation
Periapical radiographs can locate radiopaque structures in proximity to the root which can appear as dense bone islands or periapical osseous dysplasia in cases of hypercementosis. [9] The majority of affected teeth appear club-shaped due to cemental hyperplasia diffusing in a variety of severities. Most appear in the apical third of the root. [10]
Fibrodysplasia ossificans progressiva (/ ˌ f aɪ b r oʊ d ɪ ˈ s p l eɪ ʒ (i) ə ɒ ˈ s ɪ f ɪ k æ n z p r ə ˈ ɡ r ɛ s ɪ v ə /; [1] abbr. FOP), also called Münchmeyer disease or formerly myositis ossificans progressiva, is an extremely rare connective tissue disease in which fibrous connective tissue such as muscle, tendons, and ligaments turn into bone tissue (ossification).
