1. Objective:To investigate the expression differences of ADAM28 in odontogenic epithelial and mesenchymal cells and definitude the sub-cell orientation of ADAM28.

2. BACKGROUND:Odontogenic infection factor has been given much importance in the study of the etiology of secondary trigeminal neuralgia, and the theory of jaw bone cavities is proposed.

3. Dentigerous cyst (DC) is a common odontogenic cyst developed abnormally around unerupted maxillary or mandibular teeth.

4. Objective To investigate the early diagnosis and therapy for asynchronous symmetrical multiple primary keratocystic odontogenic tumor (ASMPKCOT).

5. CONCLUSION: These data show for the first time the formation of dentin and bone from dissociated odontogenic cells in the canine jaw.

6. Methods:The steps and procedures for making the clasp retained cyst plug was introduced, and it was used in 5 cases of odontogenic mandibular cysts following marsupialization .

6. try its best to gather and build good sentences.

7. The most common symptoms at the time of presentation were painful swelling of neck (95%) and fever (80%). Typical etiologies were upper respiratory tract and odontogenic infections.

8. Objective:To improve the understanding of X-ray features of the odontogenic keratocyst of mandibula .

9. When encountered in the jaws, the lesions exhibit clinical and radiographic features suggestive of several odontogenic and non-odontogenic neoplasms .

10. Conclusion Basing on the theory of "Asynchronous Symmetrical Multiple Primary", the minor primary lesions of odontogenic keratotic cystoma in other region...

11. Conclusion:ADAM28, as a plasmosin, might regulate proliferation and differentiation of odontogenic cells and play a crucial role in tooth germ development.

12. Objective It is to discuss the treatment methods of giant odontogenic keratocyst.

13. Histologically, the tumor was composed of a myxoid connective tissue with strands of odontogenic epithelium and differentiated tissue such as enamel and dentin.

14. Objectives Ameloblastoma is believed to be originated from the odontogenic epithelium, thus the ameloblastoma cells might characterize the ameloblasts and the tumor cells as well.

15. Objective:To discuss the clinical presentations, diagnosis and management guidelines of calcifying epithelioma (CE) and calcifying epithelial odontogenic tumor(CEOT).

16. Conclusion Decompression combined with curettage in local area is an effective method for giant odontogenic keratocyst.

17. Methods: The X-ray findings of 60 pathologically proven cases with odontogenic keratocyst of mandibula were retrospectively analyzed.

18. Objective:To explore the clinical value of a cyst plug in marsupialized odontogenic cysts.

19. Objective : To investigate the expression of the fibroblast growth factor receptor 3 ( FGFR 3 ) in odontogenic tumors.

20. Objective: To establish a method of in vitro cultivation of epithelial cells of keratocystic odontogenic tumors.

21. Objective : To study the characteristics of clinicopathology of peripheral odontogenic fibroma.
