Types of External Root Resorption of Replanted Teeth

Inflammatory Root Resorption after Braces. There is one type of root resorption that is unfortunately a bit more uncommon. This kind occurs after aggressive tooth movement, and it seems to have a partially genetic basis. This panoramic x-ray is from a long-time patient in our practice Idiopathic root resorption is a type of root resorption that is autoimmune in nature. It commonly occurs in people suffering from scleroderma and is often diagnosed in dental X-ray reports. However, this condition is quite rare. What is normal dental resorption Paul Abbott, B.D.Sc., M.D.S., FRACDS (Endo) | At one time, dentists were taught that there were only two types of root resorption - internal and external. As our knowledge and advances in the specialty improved, so too have the number of types of resorption You must log in to registe

Types of root resorption in permanent teeth may be broadly classified into internal and external resorption. Internal eruption has its origins in the dental pulp whereas external resorption begins in the periodontal ligament (PDL). Internal resorption is relatively rare and occurs as a result of trauma or caries-related inflammation of the pulp Tooth resorption is classified internally and externally, depending on where the loss of tooth occurs. External resorption is often easier to see than internal resorption because it commonly occurs.. 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 Root resorption in orthodontics is referred to as induced inflammatory resorption, and it is a form of pathological root resorption, in which orthodontic forces are transferred to the teeth and hyalinized areas are thus removed in the periodontal area. During the removal of hyalinized tissues, the cementum is also removed Root resorption is a challenging problem for dental practitioners. This paper presents a simple, organized classification of the types of root resorption and a discussion of the clinical and radiographic features of each. Treatment requirements or options are given, along with prognosis relative to the type of resorptive defects

EXTERNAL INFLAMMATORY RESORPTION:  External inflammatory resorption is the most common type of external resorption.It is characterized by deep, bowl-shaped depressions in the cementum and root dentine.  This type of resorption is self-limiting in nature and usually occurs following trauma In another study, root canal stenosis and external inflammatory resorption were managed by surgical root reconstruction using biodentine. 13 Biodentine can be used as an effective alternative to MTA in various types of applications in Endodontics. Management of the tooth #8 with an open apex using Biodentine required significantly less time. Abstract - Etiology of different types of root resorption requires two phases: mechanical or chemical injury to the protective tissues and stimulation by infection or pressure. Injury can be similar in various types of root resorption. The selection of proper treatment is related to the stimulation factors External inflammatory root resorption is a process that starts from minor lesions of the periodontal ligament and/or cementum, due to trauma or contamination with bacteria that induce small root resorption cavities, reaching the dentinal tubules and the root canal.1 Initially, it does not involve pulp tissue.2 It can also be caused by Pulp necrosis, trauma, periodontal treatment, orthodontics and tooth whitening are the most common stimulants of inflammatory resorption. Some other less common causes include pressure from ectopic teeth, cysts, and tumours. These cause damage to the periodontal ligament (PDL), cementum, or pre-dentine

Resorption is a widely misunderstood process; therefore, the purpose of this video was to simplify it in animation to help with patient comprehension. AAE me.. In humans, external root resorption is classified as surface, inflammatory, or replacement (noninflammatory) resorption. Internal root resorption occurs when the integrity of the outermost layer of pulp tissue is broached. It starts on the pulpal surface and extends toward the external aspect of the tooth The essence of his work was recently reviewed and reintroduced, as the original article was in Swedish.2 The etiology of root resorption has been studied over the past few decades, and the overall progress in this field of research was recently reviewed.3 The type of tooth movement performed (bodily versus tipping) was suggested to be a.

This effect is an immune response that causes osteoclastic-type destruction of the root surface. The pattern of resorption begins in the area of the cementoenamel junction, with the radiographic imaging of the affected tooth taking on the appearance of an apple core if both mesial and distal surfaces are involved Radiographic evaluation of apical root resorption with 2 different types of edgewise appliances. Results of a randomized clinical trial. [Article in English, German] Reukers EA(1), Sanderink GC, Kuijpers-Jagtman AM, van't Hof MA. Author information: (1)Department of Orthodontics and Oral Biology, University of Nijmegen, The Netherlands Type 1 lesions commonly begin resorption on the coronal third of the root, but can begin further apically. As resorption progresses, the coronal dentin often becomes involved. Eventually, dentinal loss undermines the enamel, causing it to fracture and resulting in a defect in the tooth Regardless of the type, tooth resorption has been reported in approximately 54% of dogs and 11% of teeth.33 The progression of tooth resorption is slow and compared to cats less commonly results in tooth loss. There is a significant positive association between external replacement resorption, age, and body weight in affected dogs (Tronstad) The location of this damage, and therefore the associated tissues, determines the type of resorption that occurs. Resorption cannot be simply defined as internal or external. Internal root resorption (IRR) is its own unique entity, whereas external resorption can take many forms

Root and Tooth Resorption Types, Symptoms & Treatment

Root resorption TREATMENT is challenging, as well. If you look at the tooth from the coronal view, you'll notice the location of the resorption is a little improved, making it easy to understand why we call it external cervical resorption. This resorption is at a relatively early stage of progression, but its location at the crest of bone and. Root resorption can be observed in the tooth root in cases with known and in cases with unknown etiology. Research on root resorption has focused on two aspects. First, the cellular and biological processes that occur on the root surface during the resorption. This aspect is mainly studied experimentally on animals Root resorption is a generally uncommon problem where your tooth's structure is actually eaten away. Although resorption is a natural process that happened to all of us when we were kids (think about shedding your primary teeth and getting permanent teeth), root resorption shouldn't occur in adult teeth This type of root resorption starts on an external root surface, usually around the cervical level, and progressively invades the root - going both in a coronal and apical direction (see Figure 1). Figure 1: Periapical radiograph of invasive cervical root resorption on a mandibular central incisor sorption and root resorption. Requirements for the presence of root resorption Due to the previously described inhibitory effects of organic pre-cementum and predentin, even in the presence of inflammation, an intact root is resistant to resorption. However, if an injury removes or alters the (protective) pre-dentin or pre-cementum, inflam

Root Resorption: Complications, Causes And Treatmen

External Root Resorption - Teeth & Chief

  1. External resorption is typically more severe that internal resorption. Once the trauma has occurred to the tooth, osteoclasts, a type of cell that destroys bone tissue, attach to the surface of the root and begin to dissolve the outer layer of the tooth root.This process continues to the inner root of the tooth, destroying the blood vessels and nerve tissue, and causing the crown of the tooth.

Dr. Demas will evaluate each individual tooth and any movement of the tooth through the use of X-rays. A tooth can function for a considerable number of years or a lifetime despite root resorption. It really depends on the condition of the tooth Root resorption has been described as the loss of dentin as a result of odontoclastic action. It may be a physiologic process, which can be seen in deciduous teeth or occurred due to pathologic factors such as trauma and pulpal in-flammation. Root resorption is categorized into internal or external resorption based on the location of the defec External Cervical Resorption - It is caused by trauma, periodontal treatment and teeth whitening. This forms a resorptive lesion in the cervical area of the tooth. Continuous damage to tissues leads to the growth of vertical and horizontal lesions. External Replacement Resorption - It occurs due to the fusion of root of alveolar bone to the.

Root resorption occurs in three stages: initiation, resorption, and repair. 6,7 The process may have a self-limiting characteristic and may not be clinically detected. 8 Once started, resorption depends on common factors that stimulate clastic cells, such as infection and/or pressure, to pro-gress the destruction of mineralized dental tissue When the inflammation is inside the teeth, we see internal root resorption, which is usually treated by root canal. When the inflammation is present outside of the tooth, there are several types of resorption that can occur, including inflammatory resorption, cervical resorption, replacement resorption and temporary resorption In a condition known as a tooth resorption -formerly referred to as feline odontoclastic resorptive lesion (FORL) or cervical line lesion—the dentin in a single tooth (or several simultaneously) erodes and eventually becomes irreparably destroyed. Over time, all areas of an affected tooth, from root to crown, may become involved Diagnosis given to the patient at the time lesion was first noticed: internal resorption. As you can see, a root canal was completed, but no changes noted to the lesion. Patient continued to have discomfort post root canal therapy (figure 6). Reassessment: external resorption confirmed by a 3-D scan Tooth resorption is loss of hard dental tissue, but not from decay.This means that the substance of a tooth is broken down by certain specialised body cells and then absorbed.Resorption thus causes some of a tooth, generally in the root area, to just disappear. In the developing child there is a natural physiological resorption of the roots to allow for the exfoliation, or shedding of the.

Repair-related resorption (surface resorption) is a frequent resorption type which presents itself as small cavities on the root surface that heal by new formation of cementum accommodating the reformed periodontal ligament fibers. These areas represent minor ischemic injuries to the periodontal ligament which cause resorption of soft tissue by macrophages and hard tissues by osteoclasts Microscopic areas of root resorption often repair uneventfully in cats. Tooth resorption from any cause occurs through the action of odontoclasts that remove tooth structure, creating a resorptive lacuna. In many but not all lesions, concomitant osteoblast and cementoblastic activity replaces the lost tooth with bone or cementum Root resorption is a variable to be considered in induced tooth movement (ITM). It is related to root morphology and alveolar bone crest, and also to the types of forces exerted by mechanotherapy. This histometric study evaluated the predominance of root resorption among roots of different dimensions, following ITM with different types of. 3. There are Two Main Types. Your dentist will identify which type of dental resorption you're suffering from: internal or external. Neither is particularly positive, but internal seems to be the worse of the two, as it can destroy the tooth's root without any warning Takeshita W M, Chicarelli M, Iwaki L C. Comparison of diagnostic accuracy of root perforation, external resorption and fractures using cone-beam computed tomography, panoramic radiography and.

Root resorption rate of alveolar-margin-type tumors was 37% (19/51), and that of the root-apex-type tumors was 57% (12/21). All alveolar-margin-type tumors showed spike-type root resorption, and all root-apex-type tumors were of the knife-edge type except 1 case Teeth may show elements of Type 1 or 2 resorption simultaneously (Type 3). Etiology of Types 1 and 2 in cats is not fully understood and may be specific or shared. Type 1 = inflammatory resorption (peripheral inflammatory root resorption 'PIRR'): Focal areas of resorption produce 'punched-out' and 'apple-core' type root lesions radiographically

Internal root resorption (IRR) is a particular category of pulp disease characterized by the loss of dentine as a result of the action of clastic cells stimulated by pulpal inflammation. This review article explains the etiology, the prevalence of IRR, and, in addition to the clinical data, the contribution of the three-dimensional imaging (CBCT) to the diagnosis, the clinical decision, and. Two morphologic types of external root resorption have been identified: TAB and PARR without ankylosis. TAB—Transient apical breakdown (TAB) is a temporary process in which the apex of a tooth displays radiographic evidence of resorption. However, the injured periapical root and bone returns to a normal state following repair, which may take. Internal resorption, a rare phenomenon, has been a quandary from the standpoints of both its diagnosis and treatment. It is usually asymptomatic and discovered by chance on routine radiographic examinations or by a classic clinical sign, pink spot in the crown. This paper emphasizes the etiology and pathophysiologic mechanisms involved in internal root resorption

Finding out you have a cavity isn't the best of news. But finding out it's a root cavity is even worse: if not treated, the decay can spread more rapidly than a cavity occurring in the tooth's crown surfaces.. Our teeth are basically composed of two parts: the crown, the visible tooth above the gum line, and the roots, the hidden portion beneath the gums Root resorption may occur as an unwanted side effect and may in some instances jeopardize an otherwise successful treatment. The general aim of this series of clinical investigations was to study the association between applied force, achieved tooth movement and related root resorptions The following types of tooth root resorption are distinguished: physiological at the roots of temporary teeth and pathological resorption. Depending on where resorption occurs, it is divided into internal and external. Due to the appearance, the external one is conditionally classified as substitution, superficial and inflammatory

Tooth Resorption: Is It Dangerous and Why Should You Care

  1. The last type of resorption that we'll discuss is that which occurs during orthodontic tooth movement. Root resorption or 'shortening of the roots' occurs in nearly all cases of orthodontics, but is so insignificant that it may not be possible to see it on an x ray
  2. Dear Stan, For adults, root resorption is an uncommon and troublesome dental condition in which the body's own cells eat away and dissolve tooth structure. It isn't a problem for growing kids, however; in children, resorption is the natural process that causes the roots of baby teeth to be removed, facilitating their replacement with permanent teeth
  3. What type of resorption is it (external or internal)? Where is the resorption located (buccal, lingual, mesial or distal)? Does the resorption perforate the tooth?

  6. Three types of external resorption are: Inflammatory Resorption. - Result of trauma, orthodontics, or pulpal necrosis. Replacement Resorption. - Ankylosis. Extra Canal Invasive Resorption. - Variable, may have inflammation and/or replacement. Extra Canal Invasive Resorption (ECIR) ECIR is a clinical term in use since 1998 to describe an.

Internal resorption is further divided into two types: those involving root canal shift, and those presenting with local resorption. Based on various clinical and histological features external resorption is divided into the following four categories: root surface resorption, local resorption on root surface, alternative resorption, and root. Tooth root resorption occurs when a part or parts of the tooth are destroyed. Any area of the tooth can be affected, from the dentin to the enamel. Odontoclasts are cells that are critical for resorbing tooth tissue. They are usually associated with breakdown of baby tooth roots, so that these teeth can fall out and make way for permanent teeth External Resorption. External resorption can affect the gum & outer layer or cementum of the tooth. This will cause a brittle, inflamed tooth. How to Tell If It's External Resorption. It can be difficult to distinguish between the two types of tooth breakdown as they might have similar symptoms Tooth resorption can often lead to a dentist performing a root canal. Tooth resorption is when the cells in a person's body destroy his tooth. Cells attack and wear away a person's tooth from either the inside or the outside of the tooth. These two types of tooth resorption are called internal and external

Dental Root Resorption: A Review of the Literature and a

Internal root resorption is the progressive destruction of intraradicular dentin and dentinal tubules along the middle and apical thirds of the canal walls as a result of clastic activities. It is seen as a radiolucent area around the pulpal cavity, usually of incisors and mandibular molars Type of resorption. Different types of resorption have different prognoses that range from favorable to hopeless. For example, internal resorption has a favorable prognosis, and it is relatively simple to halt. A root canal treatment will stop this resorptive process because the clastic cells involved in internal resorption reside in the pulp.

  1. Resorption is defined as a physiologic or pathologic process that results in the loss of hard tissue, such as dentin, cementum or bone. 1 Resorption is classified as either internal or external, which can be further divided into specific types. Internal resorption indicates the process is occurring within the root canal space, while external means the process is occurring at the root surface

  1. heithersay classification. The Pink Tooth. September 19, 2012. One of the reasons for a tooth appearing pink is the presence of External Cervical Resorption (ECR) or Invasive Cervical Resorption. This type of resorption has been described and classified by Heithersay. Some of the predisposing factors for ECR include: trauma, orthodontics.
  2. There are two primary types of dental resorption: Internal tooth resorption: Where the tooth is dissolving from inside the pulp towards the outside of the tooth. External (apical) tooth resorption: Where the tooth's root begins to dissolve from the outside. Resorption can often be successfully treated with root canal treatment
  3. Tooth resorption in cats is a painful condition with an unknown cause. The most commonly affected teeth are the premolars of the lower jaws. Tooth resorption is divided into specific types based on the radiographic appearance of the tooth root. With Type 1, there is destruction of the crown, but the root retains a normal appearance with a discernible periodontal ligament
  4. Frequency of Root Resorption Following Trauma. The prevalence of traumatic injuries to the teeth and their supporting structures is significant. Causes include sports injuries, falls and automobile accidents. Most injuries occur in children between the ages of 8 and 15 years; the anterior teeth are affected most frequently

Root Resorption in Orthodontic

External apical root resorption (EARR) is a permanent/irreversible loss of the apical part of a tooth root . It can be a physiologic or pathologic process. Root resorption is a common iatrogenic complication of orthodontic treatment, where the term of 'orthodontically induced inflammatory root resorption' (OIIRR) is used Pathological root resorption is related to several local and systemic factors. By definition, if an etiological factor cannot be identified for root resorption, the term idiopathic is applied. Two types of idiopathic root resorption have been observed; namely, apical and cervical If left untreated, resorption may continue to break down dentin and cementum until the tooth breaks or is no longer usable. Below is an example of how internal root resorption appears on on a diagnostic x-ray, taken from a recent case involving tooth #17 Internal root resorption (IRR) is the consequence of a chronic inflammation of the dental pulp stimulated by traumatic injury, beginning in the pulpal space and extending into the surrounding dentine. According to the resorption stage, the affected tooth can, initially, be asymptomatic, preserving pulp vitality 1

Root resorption: types and treatment

Introduction Root resorption is a complex dental application that can lead to dental loss. Different classifications are made according to the cause and location.1 Including the inflammatory root resorption, whether is predentin or on the precementum. Dental trauma, surgical procedures, excessive pressure and irritation from bleaching agents are also considered as one of the causes. of root resorption in females ( Newman, 1975 ; Kjær, 1995 ). The amount and type of tooth movement are other determinants of root resorption ( Beck and Harris, 1994 ; Janson et al., 2000 ). As for the type of tooth movement, intrusive force has been suggested as the most detrimental to the root in some studies ( Beck and Harris, 1994 ) If root fracture occurs, surgical root tip retrieval will be required.4,5. Figures 4A & 4B. The mandibular left molar (#309) has gross evidence of an FORL and a probable defect (4A). The dental radiograph (4B) shows a resorptive (external) lesion of the mesial root centered at the cementoenamel junction but minimal root resorption Causes of Cementum Resorption There may be local or systemic causes of cemental resorption. These are as follows: Local Causes Local conditions which give rise to cemental resorption are as follows: 1. Trauma from occlusion 2. Cysts and tumors 3. Periapical pathology 4. Excessive orthodontic force 5. Embedded teeth 6. Replanted and transplanted.

Management of internal root resorption in the maxillary

OBJECTIVE: This article reviews the dental literature pertaining to dental root resorption and proposes a classification system designed to facilitate communication of precise information for each type. DESIGN: A systematic review of the literature using PubMed was performed and supplemented with manual reviews of bibliographies from textbooks The purpose of this paper was to compare radiographically the prevalence and degree of apical root resorption after treatment with a fully programmed edgewise appliance (FPA) and a partly programmed edgewise appliance (PPA) in a randomized multipractice clinical trial. Two groups of patients with Class II malocclusions were treated orthodontically. The type of treatment was randomly assigned. Orthodontically induced inflammatory root resorption (OIIRR) is somewhat different from other types of TRR. The treatment protocol of teeth diagnosed with severe OIIRR or other forms of TRR always involves root canal treatment or extraction of these teeth in severe cases and prosthetic replacement Feline tooth resorption is a common & painful condition in domestic cats. Without treatment a cat is in extreme pain & may stop eating & become very ill. Over 50% of adult cats develop tooth resorption. Dr. Kressin will diagnose and treat.
