Concurrent central odontogenic fibroma (WHO Type) and traumatic bone cyst: report of a rare case

The central odontogenic fibroma (COF) was introduced into the World Health Organisation (WHO) classification of odontogenic tumors in 1971 (1). Thereafter, further attempts were contemplated to simplify and classify this tumor. Wesley et al. [1975] (2) and Gardner [1980] attempted to clarify the diagnostic criteria of COF. However, COF still remains somewhat controversial, causing confusion due to its nature and definition. Even the 2005 WHO definition cannot specifically distinguish COF from other similar lesions (1,2).
