An Ultrastructural Study of Tooth Resorption in the Kitten

Journal of Dental Research, 1986
Eleven kittens of various ages were used to obtain teeth in situ at differing stages of exfoliation. The teeth were processed by routine techniques for examination by light and transmission electron microscopy. The dental hard tissues were eroded by odontoclasts supported by numerous blood vessels, fibroblasts, and macrophages.

Dental Pathology of the Iberian Lynx (Lynx pardinus), Part II: Periodontal Disease, Tooth Resorption, and Oral Neoplasia

Journal of Veterinary Dentistry, 2018
The Iberian lynx is an endangered felid that has been subject to an intensive, ongoing conservation program to save it from extinction. Identification of dental pathologies could play an important role in the survival of this endangered species.

Does medication administration affect the rate of orthodontic tooth movement and root resorption development in humans? A systematic review.

European Journal of Orthodontics, 2020
BACKGROUND Recently, the potential impact of different medications on the rate of orthodontic tooth movement and the associated root resorption has been systematically reviewed in animal studies and various effects have been shown.

Equine odontoclastic tooth resorption and hypercementosis

The Veterinary Journal, 2008
A poorly described, painful disorder of incisor and canine teeth, variably causing periodontitis, with resorptive or proliferative changes of the calcified dental tissues, has recently been documented in aged horses. No plausible aetiopathogenesis for this syndrome has been recorded.

Internal inflammatory root resorption: the unknown resorption of the tooth

Endodontic Topics, 2006
Internal inflammatory root resorption is a relatively rare resorption that begins in the root canal and destroys surrounding dental hard tissues. Odontoclastic multinuclear cells are responsible for the resorption, which can grow to perforate the root if untreated.

Idiopathic tooth resorption in association with metaplasia

Oral Surgery, Oral Medicine, Oral Pathology, 1954
Abstract 1. 1. The pathogenesis of idiopathic tooth resorption accompanied by metaplasia is reviewed, a summary of the present-day viewpoint is given, and a case is fully presented and discussed. 2. 2. The protective function of the periodontal membrane and the enamel cuticle is stressed. 3. 3. Attention is drawn to the strong possibility

External resorption associated with tooth eruption

Journal of Clinical Pediatric Dentistry, 2001
A case is presented with severe resorption on the mesial root of the mandibular first permanent molar in a patient with Juvenile Periodontitis. The follicle of the bicuspid is seen in contact with mesial root of the molar.

Cracked tooth: An etiology for “idiopathic” internal resorption?

Journal of Endodontics, 1986
A case is presented, with accompanying clinical and histological findings. It is likely that the crack, which communicated with the pulp, was the inciting cause of the irreversible pulpitis and resorption. Without careful clinical examination, this crack might have been undetected and could easily have been classified as “idiopathic” internal ...

Dental trauma on primary teeth at different root resorption stages—A dynamic finite element impact analysis of the effect on the permanent tooth germ

Dental Traumatology, 2019
BACKGROUND/AIM Dental trauma is a common emergency in children with primary teeth. The aim of this study was to determine stress propagation to the permanent tooth germ and surrounding bone and soft tissues during dental trauma to primary central ...

Internal Resorption Complicating Orthodontic Tooth Movement

British Journal of Orthodontics, 1984
A case report is presented of an orthodontic patient who suffered internal resorption and a consequent ‘pink spot’ affecting a maxillary central incisor. Its management is outlined. The aetiology and possible cellular events responsible are discussed.
