Q

What differences were detected between this study and the UC davis data (reported biopsies for 1995-2001) with regards to the prevalence of odontogenic tumors in biopsy samples, and what is the likely origin of the discrepancy?

A

This study had more odontogenic tumors (34% versus 13%) In the UC Davis data they had a category for hyperplasias, which included POF’s separate from odontogenic tumors.

Note that this is the table from verstraete chapter 39, NOT the Fiani article Clinicopathologic characterization of odontogenic tumors and focal fibrous hyperplasia in dogs: 152 cases (1995–2005) (which is also important)
