| Multilocular lesions often appear/are described as _______________ | soap bubble appearance |
| Malignant or aggressive conditions often have what kind of margin in radiographic lesions ? | i'll defined margins |
| Radiographically lesions that have clearly defined or well-demarcated margins are associated with what type of lesions. | Benign and less aggressive lesions |
| Define resorption | destruction of the root |
| What term is used when there is "movement toward each other" | convergence |
| What term is used when there is "movement away form each other" | divergence |
| What lesion am I? Etiology: Is an inflammatory lesion that occurs because of a reaction to a low-grade inflammatory stimulus such as trauma, pulpitis, or necrosis. Normally involves the apex of the root | Focal sclerosing osteomyelitis |
| Focal sclerosing osteomyelitis radiographic appearance | radiograph sometimes exhibits a varying radiopaque area at the apex of the tooth and surrounding area |
| Focal sclerosing osteomyelitis often affects what age group and usually affects what teeth? | young adults and first molars |
| Break down and define the words in focal sclerosing osteomyelitis | focal=one area sclerosing= dense/thick bone/scarring (radiodense) osteomyelitis=inflammation of the bone localized dense inflammed bone |
| What treatment options are there for focal sclerosing osteomyelitis | endodontics, extraction, restoration of the tooth/teeth, or no treatment |

| True or False: Cementoblastoma, Odontoma, Osteoma,Gardner Syndrome are traumatic or inflammatory lesions. | False: they are neoplasms |
| “True tumor of cementum” or neoplasm of cementoblasts Symptoms: possible pain; asymptomatic Location: Posterior Md or Mx- Tumor is attached to the tooth root; appears as a radiopaque calcified mass with a radiolucent halo (periodontal ligament space) | Cementoblastoma |
| What are the tissue components of a hamartoma? | mixture of enamel, dentin, cementum, and pulp |
| What are the two forms of odontomas? | complex and compound |
| Complex odontomas consist of ? | consists of a collection (mixture) of hard tissues that include deposits of enamel, dentin, cementum, and pulp all together in a masslike calcified form. |
| Compound odontomas resemble? | resembles small teeth and appears in a collection of calcified material. |
| Describe the radiographic appearance of a cementoblastoma | radiopaque calcified mass with a radiolucent halo; bowling ball |
| Who am I: Mixed odontogenic tumors are comprised of both epithelial and *mesenchymal tissues. Treatment: Excision (surgical removal) is the treatment of choice Prognosis: excellent Two forms: complex and compound | Odontoma |
