OBJECTIVES: To compare the polarization colors of collagen fibers of odontogenic keratocyst (OKC), radicular cyst, dentigerous cyst, and adenomatoid odontogenic tumor (AOT) with reference to their biological behavior.
STUDY DESIGN: Twenty cases each of OKC, radicular cyst, dentigerous cyst, and AOT were stained with picrosirius red stain and studied under polarized light.
RESULTS: A predominance of green to greenish yellow thick fibers was noted in OKC and AOT as compared to dentigerous cyst and radicular cyst. There was no significant difference between the polarization colors of the thin fibers in all the three groups.
CONCLUSION: The stroma of OKC and AOT consists of poorly packed or pathologic collagen and plays a role in its neoplastic behavior.
