Variations of Normal:
–Genetic and ethnic predisposition for development. –Masticatory stresses contribute to their growth as well as injuries and blunt force trauma. –No treatment unless interference with appliances. |
Torus palatinus, mandibular torus |
|
|
Variations of Normal: –Asymptomatic,exuberant growth of compact bone occurring along the facial surfaces of themaxilla and mandible. –Fromirritation and occlusal forces. |
Exostosis Plural is Exostoses |
|
|
Infections: An inflammatory process of the bone and bonemarrow caused by infection. Initial infection is normally from abacterial sources such as staph, strep, actinomyces and other organisms. Abscesses, periodontal infections, jawfractures, and cysts are often involved in the initiation. |
Osteomyelitisis |
|
|
Infections:
aka. Gerre Osteomyelitis. Proliferative inflammatory response of the periosteum to infection or irritants. Can originate from abscesses or periodontal infection, bacteremia or jaw fracture. Bony, hard protuberance. Antibiotics to treat and removal of teeth involved or area affected. Bone will resolve over time. |
Chronic Osteomyelitis with Proliferative Periostitis. |
|
|
Neoplasms:
Most commonly occurring odontogenic tumor. Classified as an odontogenic tumor which arises from epithelial or mesenchymal remnants of tooth-forming tissues. Occur more in 40’s to 50’s. 80% in mandibular molar region. Multilocular or unilocular soap-bubble appearance. Malignancy is rare. Excision to treat. |
Ameloblastoma
|
|
|
Neoplasms:
Probably originates from the remnants of the enamel organ. Associated with unerupted teeth. 20 to 50 year olds. More often in the mandible. Benign but invasive. Slow-growing, painless jaw expansion. May see calcifications within the tumor islands. Surgical removal to treat. |
Calcifying Epithelial Odontogenic tumor or Pindborg tumor. |
|
|
Neoplasms:
Benign neoplasm composed of cementum-like calcifications and bony components. Cause is not known. Occurs most often in 30’s to 40’s. Generally occurs in the premolar and molar regions of the mandible. Slow-growing, painless and expansile. Surgical removal to treat. |
Ossifying Fibroma |
|
|
Neoplasms:
Believed to be a reactive lesion or reparative response to trauma or other local factors. Usually found in the mandible. Often found under age 20. Radiolucent with expanding margins but may penetrate through bone into soft tissue. Painless. Excision by curettage to treat. |
Central giant cell granuloma |
|
|
Neoplasms: Most common primary malignant tumor found inbone-malignant neoplasm of osteoblasts. Associated with Paget’s disease in olderpeople or past radiation exposure. Mandible most common area affected. May have “sunburst” pattern. Pain, swelling, loose teeth or numbness anddysesthesia. Surgicalremoval and chemotherapy to treat. |
Osteosarcoma or Osteogenic sarcoma |
|
|
Neoplasms: Malignant tumor of cartilage. Less common than osteosarcoma. Less than 1% are found in the maxilla ormandible. May or may not be painful or cause swelling. Surgical excisionto treat. |
Chondrosarcoma. |
|
|
Neoplasms: Malignant bonetumor. 2nd most common tumor in children. Pain, swelling, numbness and tooth mobility. Ramus of the mandible most common areaaffected. Has moth-eaten appearance radiographically. Surgical removal, chemotherapy and radiationto treat. |
Ewing’s sarcoma. |
