oral patho test 1 Flashcards
(Brittle bone disease) hereditary,osteoblast dysfunction. Clinical features: blue sclera & deafness, multiple bone fractures , porous bones, shortened roots, obliterated pulp chamber, & decreased radiopacity of the dentin.
Osteogenesis Imperfecta
Rock hard bone, eyes wide set, teeth poorly calcified, radiographically appears homogeneously opaque
Osteopetrosis
1 in 2000 births, causes lack of nutrients for babies.
Cleft palate
what is the least significant form of a cleft palate?
Bifid uvula
Family disease, large head, with bulding forehead, open frontals throughout life absence of clavicles. poorly developed maxilla delay in shedding of primary teeth and eruption of perm. Gemination or concrescence may appear.
cleidocranial dysostosis
unknow etiology. Bone is excessively vascular. manifests in middle life or later. thickening of bones. Maxilla and above are effected. NOT mandible. loss of well defined lamina dura.
Pagets Disease ( Osteitis Deformans)
Etiology: a result of an inflammatory process produced by an organism. INFECTION OF BONE cured with antibiotics. mandible more likely to get infection because it has less WBCs to fight infection
Osteomyelitis
Extra bone around the tooth. Associated with LARGE FILLINGS and CAVITITES. Reaction of bone near the apices of teeth due to a low grade infection. Radiopaque area ectending from the area of the tooth apex.
Condensing Osteitis
BONE DEATH DUE TO RADIATION.aftermath of therapeutic radiation treatment mature bone and connective tissue itself is not generally affected but blood vessel lining within the bone and soft tissue is destroyed,
Osteoradionecrosis, Osteochemonecrosis.
a benign tumor of bone arising from the periosteum bone or embryonic. Surgical removal. Always buccal usually unilateral more common on mandible, premolar or molar area
osteoma
benign outgrowth of normal bone often found on the maxilla. Tori are exostosis found in a characteristic location. Buccal side only.
Exostosis
Possible response to trauma, irregular occlusion, hereditary. Located chiefly in midline or the palate and on lingual of mandible in premolar area. May be single, unilateral. Difficult for denture marking. Surgical removal with high reoccurence rate
Torus
giant c ells in the periodontal membrane as a result of trauma. radiolucent area with well demarcated borders, loosening of teeth. Big cell with multi nuclei
Central Giant Cell Granuloma
Same as Central giant cell granuloma but is in the connective tissue, fluid filled
Peripheral Giant Cell Granuloma
unknown etiology. over expression due to allergic reaction. proliferation of large mononuclear cells of reticuloendothelial system. punched out areas of jaws seen on xray. mostly in boys and young men. Usually ends in death
Eosinophilic Granuloma
