av E Nyström · 2018 · Citerat av 2 — Aim: The overall aim of the study was to register external apical root resorption in maxillary incisors before and after retention phase with removable appliance.

This paper aims at exposing the foundations or reasons why, in cases of external tooth resorption, including those of orthodontic origin, one should not perform a root canal to treat it. That should be done only to teeth with contamination or pulp necrosis, to remove the periapical inflammation indu …

Sometimes external resorption is not easy to diagnose from the radiograph when the canal outline is indistinct. Three types of external resorption are: External inflammatory root resorptions are pathologies that are difficult to treat. The treatment aims to eliminate the cause or stimulating factors of clastic cells such as infection and/or pressure. The size and location of the lesions are limiting factors for the treatment and maintenance of the affected tooth. 2012-01-03 2020-09-05 2019-05-29 External resorption can be classified into four categories by its clinical and histologic manifestations: external surface resorption, external inflammatory root resorption, replacement resorption, and ankylosis.

As time goes by and the degree of resorption increases, the tooth may become symptomatic…this may present in the form of a periradicular abscess (an abscess around the root of the tooth) and increased tooth mobility. The effects of external (cervical) resorption (ECR), which you seem to be describing, occur near the gum line at the cervical (“neck-like”) region of a tooth. In its early stages, this condition may produce pink spots where the enamel is undermined and filled with the pinkish cells that do the damage. External inflammatory resorption is a potential consequence of trauma to teeth that may occur when the external root surface has been damaged and the root canal system has become infected. External inflammatory resorption can lead to loss of the tooth if it is not managed in a timely manner.

One of these is external resorption after trauma. In such cases, resorption is caused by inflammation in the pulp and/or in the periodontal tissue. Permanent tooth roots can also be affected by resorption caused by pressure in the periodontal ligament, seen for example, in connection with tooth eruption, orthodontic tooth movement or tumors.

Ökat Bp -> minskat angiotensin 2 -> minskad resorption i tubuli. Definition av inhibition av internal sphincter -> viljemässig kontraktion av external sphincter. Osteonecrosis of the external auditory canal has been reported with Alendronate is a bisphosphonate that inhibits osteoclastic bone resorption with no direct  RESEARCH FUNDING / Total sum of acquired external funding 1.3 million EUR Leaf N resorption efficiency and litter N mineralization rate have a genotypic  Class U2: internal indentation > 50% of wall thickness and external contour straight. /indentation <50% anomaly. Resorption anomalies.

This form of resorption occurs in the cervical region of a tooth. There have been many different causes for this resorption suggested such as trauma, orthodontic movement, intracoronal bleaching, periodontal root scaling, etc. […] External resorption - Treatment Since the source of the lesion is not in the pulp, endodontic treatment by itself is of no assistance in dealing with the source of the problem. Idiopathic external resorption differs from classic "replantation" or "traumatic" external resorption because of the localized nature of the lesion. External Root Resorption is caused by Periodontal Ligament Cells. As I mentioned, root resorption is pretty uncommon. In my 20+ years of practicing dentistry, I’ve only come across a few cases.

2019-02-13 External cervical root resorption arises at the cervical margin as a result of various insults to the periodontium (periodontal disease, trauma, tooth bleaching, orthodontic treatment, surgery). The pattern of resorption may vary according to the aetiology, type and severity.

The study of root resorption and its immunopathogenesis is extremely important for preserving teeth within the oral cavity. Resorption may be inflammatory or by  10 Sep 2016 Clinical radiographs demonstrating (a, b) external inflammatory root resorption associated with apical pathosis, (c) external replacement  4 Sep 2019 Learn more about how to address invasive cervical root resorption, which is also known as 'extra-canal invasive root resorption,' and why  Root resorption is the process in which the body breaks down and absorbs tissue surrounding a tooth.

27 Jun 2018 Orthodontic treatment can result in root resorption (RR). Traditional two- dimensional (2D) data exhibit magnification, deformation and 

Three types of external resorption are: Internal vs External Resorption Resorption is considered to be internal if the original site of the resorption starts in the pulp and external if the original site is the periodontal ligament. Internal Characteristics External b Asymptomatic b b Pink discoloration b b Pulp test usually normal b Defect moves with X-ray angulations b External inflammatory root resorptions are pathologies that are difficult to treat. The treatment aims to eliminate the cause or stimulating factors of clastic cells such as infection and/or pressure. The size and location of the lesions are limiting factors for the treatment and maintenance of the affected tooth. External Root Resorption is similar to internal root resorption but the resorption occurs from the outside and goes inwards. Similar causes have been related to external root resorption but no theoretically proven cause has been determined.
