first step in differential diagnosis of abnormality
anatomical, artifactual or pathological?
what is an odontoma
bengin tumour composed of dental tissues
subtypes of odontoma
compound (ordered dental structures)
complex (disorganised mass of dental tissues)
managment of odontoma
excision
what is idiopathic osteosclerosis
localised area of increased bone density of unknown cause
what is sclerosing osteitis
localised area of increased bone density in response to inflammation
what is hypercementosis
excessive deposition of cementum around root
what is cementoblastoma
benign odontogenic tumour of cementum
what are tori
bony tuberances of normal bone at characteristic sites:
torus mandibularis
torus palatinus
what is an osteoma
benign tumour of bone
what is gardner syndrome
characteristic by triad of clinical manifestations
1. colorectal polyposis
2. osteomas
3. soft tissue tumours
what is cleidocranial dysplasia
rare gentic conditions with various skeletal defects e.g., delayed eruption, mutliple supernumerary teeth, unerupted secondary teeth, hypoplastic maxilla with high arched palate
what is osteomyelitis
inflammation of bone and bone marrow due to bacterial infection
what is osteoradionecrosis
bone death resulting for irradiation
what is mronj
bone death associated with anti-resoprtive or anti-angiogenic drugs
what is central giant cell granuloma
slow growing lesions causing expansion of bone and displacement of teeth
what are fibro-osseous lesions
rare non inheritable conditions where normal bone is replaced by connective tissue and abnormal bone
main types:
cemento-osseous dysplasia
fibrous dysplasia
ossifiying fibroma
what is Paget’s disease of bone
chronic condition causing disordered remodelling of bone
what is osteoporosis
decreased bone mass
