Feline odontoclastic resorption lesion (FORL) is a syndrome in cats characterized by resorption of the tooth by odontoclasts, cells similar to osteoclasts. FORL has also been called Feline tooth resorption ( TR ), neck lesion , cervical neck lesion , cervical line erosion , feline subgingival resorptive lesion , feline caries , or feline cavity .
Resorption of the root of the tooth, or root resorption, is the progressive loss of dentin and cementum by the action of odontoclasts. [4] Root resorption is a normal physiological process that occurs in the exfoliation of the primary dentition .

Physiological bone resorption is an integral part of bone functioning, while the bone is constantly growing thanks to two processes — breakdown and formation of bone tissue. [23] Locally, it could be manifested in tooth eruption when the movement of a tooth follicle is followed by an active resorption of jaw bone tissue.
During this process, the tooth root cells become necrotic (dead) and will activate the immunologic mechanism of the body to attempt to remove this necrotic layer and literally eats away the tooth root. This is called "root resorption". It is a slow, but non-painful, process that is sometimes not observed by x-rays for years. Once this process ...
Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.
Periapical is defined as "the tissues surrounding the apex of the root of a tooth" and a cyst is "a pathological cavity lined by epithelium, having fluid or gaseous content that is not created by the accumulation of pus."
This article follows the 1999 classification, although the ICD-10 (10th revision of the International Statistical Classification of Diseases and Related Health Problems) differs significantly. The latest World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions was held in 2017. this updated classification ...
