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 .
Smilodon started developing its adult saber-teeth when the animal reached between 12 and 19 months of age, shortly after the completion of the eruption of the cat's baby teeth. Both baby and adult canines would be present side by side in the mouth for an approximately 11-month period, and the muscles used in making the powerful bite were ...
Cats are carnivores that have highly specialized teeth. There are four types of permanent teeth that structure the mouth: twelve incisors , four canines , ten premolars and four molars . [ 1 ] The premolar and first molar are located on each side of the mouth that together are called the carnassial pair.
While resorption of bone is a normal physiological response to stimuli throughout the body, root resorption in permanent dentition and sometimes in the primary dentition is pathological. The root is protected internally (endodontium) by pre-dentin and externally on the root surface by cementum and the periodontal ligament.
An animal's dentition for either deciduous or permanent teeth can thus be expressed as a dental formula, written in the form of a fraction, which can be written as I.C.P.M I.C.P.M, or I.C.P.M / I.C.P.M. [10] [11] For example, the following formulae show the deciduous and usual permanent dentition of all catarrhine primates, including humans:
Non-eruption of non-ankylosed teeth occurs due to an eruption mechanism that has failed leading to a posterior unilateral/bilateral open bite. [28] Infra occlusion is the primary hallmark of PFE. Primary teeth are most commonly affected and normally all teeth distal to the most mesially affected tooth will show characteristics of this disease.
DJ Unk, the Atlanta MC known for his early 2000s hits including “Walk It Out” and “2 Step," died after suffering a cardiac arrest this week, according to his wife.
The variations usually lie in the morphology, number, development timeline, and types of teeth. [8] However, some mammals' teeth do develop differently than humans'. In mice, WNT signals are required for the initiation of tooth development. [9] [10] Rodents' teeth continually grow, forcing them to wear down their teeth by gnawing on various ...
