Feline odontoclastic resorptive lesions

An unsolved enigma in veterinary dentistry
      Feline odontoclastic resorptive lesions (FORLs) are a common and frustrating finding in small animal practice and represent the most common dental disease in cats. Sophisticated dental treatments promise neither cure nor permanent improvement of affected teeth. Research on the etiology of FORLs has not been rewarding in recent years, and the causative factors contributing to the development of FORLs are still unknown. Despite the clear evidence of a resorptive process, this condition in cats was often termed caries or erosion. Furthermore, the anatomic connotation of the term neck lesion and the use of various other terms often led to confusion and misdiagnosis of FORLs. These lesions initially start in the periodontal ligament and cementum below the gingival margin and not at the cervical portion of the tooth crown. The authors of this article favor the term feline odontoclastic resorptive lesions because it most accurately reflects the disease process.
