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 .
External cervical resorption is a localised resorptive lesion in the cervical area of the tooth, below the epithelial attachment. It is distinguished from external inflammatory root resorption in that it rarely involves the pulp. When at least 3 teeth are affected, it is referred to as multiple idiopathic cervical root resorption.
They address various conditions such as jaw fractures, malocclusions of the teeth, oral cancer, periodontal disease, and unique veterinary conditions like feline odontoclastic resorptive lesions. Additionally, some animals have specialized dental workers like equine dental technicians, who perform routine dental work on horses.
In cats, abnormal odontoclast activity can cause feline odontoclastic resorptive lesions, necessitating extraction of the affected teeth. Osteoclasts play a major role in orthodontic tooth movement and pathologic migration of periodontally compromised teeth.
These lesions can grow large because they apply pressure over the bone, causing resorption. The toxins released by the breakdown of granulation tissue are one of the common causes of bone resorption. There are two schools of thought regarding cyst expansion. [5] Complementary response to inflammation; Chemical reaction with Interleukin and ...
Human Tooth Diagram. Cementoma is an odontogenic tumor of cementum.It is usually observed as a benign spherical mass of hard tissue fused to the root of a tooth. [1] It is found most commonly in the mandible in the region of the lower molar teeth, occurring between the ages of 8 and 30 in both sexes with equal frequency . [1]
The dentigerous cyst commonly involves a single tooth and rarely affects multiple teeth. The most frequently involved tooth is the mandibular third molar followed by the maxillary canine, but they may be associated with supernumerary or ectopic tooth. Any permanent tooth can be involved.
Tooth ankylosis refers to a fusion between a tooth and underlying bony support tissues. In some species, this is a normal process that occurs during the formation or maintenance of the dentition. [1] By contrast, in humans tooth ankylosis is pathological, whereby a fusion between alveolar bone and the cementum of a tooth occurs.
