Abstract

Investigation of cyclooxygenase (COX)-2 in dentigerous cyst and ameloblastoma may help to improve understanding of the nature and behavior of odontogenic cysts and tumors, and in addition may eventually represent a definitive target for a pharmacological approach in the management of these lesions. The aim of this study was to evaluate COX‑2 expression and its correlation with the proliferation of odontogenic epithelium in these lesions. Dentigerous cysts (n=16) and ameloblastomas (n=17) were evaluated. Detection of Ki‑67 and COX‑2 protein expression was conducted by immunohistochemistry. Data were statistically analyzed using Mann‑Whitney U test and Spearman's rank correlation coefficient. No significant differences were found in the expression of Ki‑67 and COX‑2 between dentigerous cysts and ameloblastomas (P>0.05). A significant positive correlation (P=0.018) and highly significant positive correlation (P=0.004) were found between Ki‑67 and COX‑2 expression in the odontogenic epithelium of dentigerous cyst and ameloblastoma, respectively. COX‑2 was expressed in the odontogenic epithelium of dentigerous cyst and ameloblastoma. It may contribute to local extension of these lesions by increasing the proliferation of their odontogenic epithelial cells.
