CE Corner Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology Continuing Education Evaluation Form Introduction to the CE Corner Program Dentists and physicians may participate in the CE Corner program by reading three of the selected Continuing Education (CE) articles in this issue of Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology to be eligible for 2 hours of continuing education credit. To earn credit, read any three of the articles listed below which are designated for CE credit and answer the accompanying questions. The processing fee for the CE Corner Evaluation Form is $20. A certificate awarding 2 hours of continuing education credit will be mailed to you within 6-8 weeks. It is then your responsibility to maintain a record of credit received. ACOMS Continuing Education Sponsor Approval The American College of Oral and Maxillofacial Surgeons (ACOMS) is an ADA CERP and AGD Recognized Provider. Please note: State, regional, and national licensing board requirements for CE vary. Check with your licensing board for further information. Author Disclosure It is the policy of ACOMS to ensure balance, independence, objectivity, and scientific rigor in scientific/educational activities. All faculty participating in an ACOMS activity are required to disclose all commitments to or relationships with industry. This requirement includes relationships with pharmaceutical companies, biomedical device manufacturers or distributors, or others whose products or services may be considered to be related to the subject matter of the scientific/educational activity. The principal intent of requiring disclosure is not to prevent an author with dual commitments from publishing an article. Disclosure is requested so that participants in the activity may formulate their own judgments regarding the article in the light of full disclosure of related information. Authors have also been required to disclose to the reader whether they will discuss unlabeled or investigational product usages within their article. Disclosure of this information is listed within the author information section at the beginning of each article. Statement of Educational Purpose Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology is a journal dealing specifically with oral and maxillofacial surgery, oral medicine, oral and maxillofacial pathology, oral and maxillofacial radiology and endodontology. Its mission and educational purpose are to promote the science and the art of oral and maxillofacial surgery, these related fields and the betterment of the public health. A flexible curriculum of articles is developed annually by the Journal’s editorial board to accommodate the diversity of practice types within OOOOE’S readership. The CE Corner CE activity allows readers to determine their own educational needs and to assist the editors in addressing their needs in future issues. The CE Corner program allows participants to: (1) select and read three articles per issue to gain new information on OMS topics of particular interest, (2) answer the related questions and (3) think carefully about how this new information may influence their own practices.

Oral and Maxillofacial Pathology Primary intraosseous odontogenic carcinoma arising in an odontoenic cyst or de novo: A clinicopathologic study of six new cases 1. The majority of cases of primary intraosseous odontogenic carcinoma occur in the: A. anterior mandible. B. posterior mandible. C. anterior maxilla. D. posterior maxilla. E. The premise is false. There is no anatomic site of predilection in the jaws. 2. The most common microscopic appearance of primary intraosseous odontogenic carcinoma arising from an odontogenic cyst is: A. mucoepidermoid carcinoma. B. squamous cell carcinoma. C. ameloblastoma with cytologic atypia. D. undifferentiated carcinoma. E. verrucous carcinoma. 3. The prognosis of primary intraosseous odontogenic carcinoma is best considered: A. relatively good, with little risk of metastatic disease. B. relatively good, although there is significant risk of local recurrence. C. Fair, with an 80% five year survival. D. Poor, with a 40-50% five year survival. E. Dismal, with less than a 30% two year survival. 4. The cyst most commonly found to be the origin of primary intraosseous odontogenic carcinoma is: A. odontogenic keratocyst.

Oral and Maxillofacial Radiology Effects of scintillator on the detective quantum efficiency (DQE) of a digital imaging system 1. An ideal imaging system would have a detective quantum efficiency (DQE) of: A. 100% B. 0% C. 1 D. a + c E. b + c 2. Detective quantum efficiency (DQE) has been found to be a good indicator of observer performance in reading radiographs for endodontic measurement purposes. True/False 3. As a scintillator combined with a charge-coupled device, cesium iodide (CsI) was found to outperform both gadolinium oxysulfide and lutetium transparent optical ceramic in terms of the obtained detective quantum efficiency. True/False 4. Using a 70 kVp X-ray generator, gadolinium oxysulfide absorbs about 2.5 times more X-ray photons from the resulting beam than does cesium iodide (CsI). True/False 5. Detective quantum efficiency measurements with production sensors are likely to outperform those obtained with the tested prototypes due to better CCD/ scintillator coupling. True/False

In this study 50 human periapical lesions were examined immediately after extraction. What number of cases contained vital tissue in the apical portion of the root canal? A. 18 B. 23 C. 32 D. 41 E. 50 4. In this study 50 human periapical lesions were examined immediately after extraction. What percentage of cysts found were true cysts? A. 14% B. 19% C. 35% D. 50% E. 62%
