FORL
Feline Odontoclastic Resorptive Lesions
This report was written in an attempt to summarize old and new theories and scientific
results regarding FORL (Feline Odontoclastic Resorptive Lesions). Several different kinds
of treatment are presented in this study. Among them teeth extraction and crown
amputation seems to give the best long-term results. It seems clear that the domestic cat of today have no trouble digesting dry foods without their teeth. The most accurate way to diagnose FORL is by using intraoral dental radiology technique. Over one third of the cat population are affected by FORL. This disease most commonly affects middle-aged
females, and Asian breeds seem to be predisposed. FORL has been detected in both captive
and wild large cats (such as lions, leopards, cougar?) as well as in wild or domestic small cats. Most authors referred to in this report believe that the lesions are a result of odontoclastic activity. What triggers this activity still remains unknown.
