Description: Tooth resorption is a process where the structure of a tooth is broken down and absorbed by the body.
Type: Tooth resorption is generally not classified as a single disease with a specific type of genetic transmission. The condition involves the breakdown and absorption of the tooth structure by cells called odontoclasts. It can be associated with various factors, including trauma, inflammation, and certain systemic conditions. Some studies suggest a potential genetic component in susceptibility, but there is no clear pattern of inheritance identified. Therefore, it is not accurately described by a specific genetic transmission type.
Signs And Symptoms: Tooth resorption, also known as root resorption, is a condition where the body begins to break down and absorb the structures that support the teeth. This can affect different parts of the tooth, including the root and sometimes the crown.

**Signs and Symptoms:**
1. **Pain and Discomfort:** Some people may experience tooth pain or sensitivity, particularly when chewing.
2. **Inflammation and Swelling:** There might be noticeable swelling or inflammation in the gums around the affected tooth.
3. **Tooth Mobility:** Affected teeth may become loose or feel different when biting down.
4. **Color Changes:** Discoloration, such as a pinkish hue, may be visible if the resorption affects the internal structures.
5. **Gum Irritation:** The gums around the affected area might become red and irritated.
6. **Asymptomatic Cases:** In some instances, patients might not experience any symptoms, and tooth resorption is only detected through dental X-rays.
Prognosis: The prognosis for tooth resorption varies depending on the extent and type of resorption. Early detection can lead to more successful management and outcomes. In some cases, treatment can halt the progression, but in advanced stages, affected teeth may need to be extracted. Regular dental check-ups are essential for managing and monitoring the condition.
Onset: Tooth resorption, also known as dental resorption, is the process in which the body breaks down and absorbs the structures of a tooth. The onset of tooth resorption can vary widely and can be influenced by several factors, including trauma, infection, or underlying health conditions. The condition can occur at any age but is often noticed in adults undergoing orthodontic treatment or after dental trauma. It may present initially without noticeable symptoms until it progresses to more advanced stages, where pain, swelling, or noticeable changes in the tooth structure may occur. Regular dental check-ups are essential for early detection.
Prevalence: Tooth resorption is relatively common, particularly in cats, where it affects between 20% to 75% of adult cats, depending on the population studied. In humans, it is less common but can occur due to various factors such as trauma, orthodontic treatment, or underlying systemic conditions.
Epidemiology: Tooth resorption is a process where the structure of a tooth breaks down and is absorbed into the surrounding tissue. It is more common in certain populations and under particular conditions:

- **Epidemiology**: Tooth resorption can affect both primary (baby) and permanent teeth. It is relatively common in children as part of the normal shedding process of primary teeth. In adults, it can occur due to trauma, orthodontic treatment, or inflammatory conditions such as chronic pulpitis or periodontitis. The incidence in adults is less common compared to children. External resorption is found more frequently in individuals who have undergone orthodontic procedures. Additionally, internal resorption, though rarer, may be triggered by trauma, infection, or other underlying health issues. In domestic cats, particularly, idiopathic tooth resorption is quite prevalent.

- **Nan**: Not applicable (nan).
Intractability: Tooth resorption is not necessarily intractable, but it can be challenging to manage, depending on its stage and severity. Early detection and treatment can sometimes halt or slow the process, but advanced cases may require tooth extraction.
Disease Severity: Tooth resorption can vary significantly in severity:

1. **Mild:** Small lesions that may not cause noticeable symptoms; often detected incidentally during dental examinations.
2. **Moderate:** More extensive lesions that can cause discomfort or sensitivity, potentially affecting the structural integrity of the tooth.
3. **Severe:** Significant destruction of the tooth structure, leading to pain, substantial tooth damage, and possible tooth loss; urgent dental intervention is usually required.

Prompt diagnosis and management are essential to prevent progression and alleviate symptoms.

Pathophysiology: The pathophysiology of root resorption is not completely understood. It is postulated that osteoclasts are the cells responsible for the resorption of the root surface. Osteoclasts can break down bone, cartilage and dentin.Receptive activator of nuclear factor kappa-B ligand (RANKL), also called osteoclast differentiation factor (ODF) and osteoprotegerin ligand (OPGL), is a regulator of osteoclast function. In physiological bone turn over, osteoblasts and stromal cells release RANKL, this acts on macrophages and monocytes which fuse and become osteoclasts. Osteoprotegerin (OPG) is also secreted by osteoclasts and stromal cells; this inhibits RANKL and therefore osteoclast activity.
One thought is that the presence of bacteria plays a role. Bacterial presence leads to pulpal or peri-periapical inflammation. These bacteria are not mediators of osteoclast activity but do cause leukocyte chemotaxis. Leukocytes differentiate into osteoclasts in the presence of lipopolysaccharide antigens found in Porphyromonas, Prevotella and Treponema species (these are all bacterial species associated with pulpal or periapical inflammation).Osteoclasts are active during bone regulation, there is constant equilibrium between bone resorption and deposition. Damage to the periodontal ligament can lead to RANKL release activating osteoclasts. Osteoclasts in close proximity to the root surface will resorb the root surface cementum and underlying root dentin. This can vary in severity from evidence of microscopic pits in the root surface to complete devastation of the root surface.
When there is insult leading to inflammation (trauma, bacteria, tooth whitening, orthodontic movement, periodontal treatment) in the root canal/s or beside the external surface of the root, cytokines are produced, the RANKL system is activated and osteoclasts are activated and resorb the root surface.
If the insult is transient, resorption will stop and healing will occur, this is known as transient inflammatory resorption. If the insult is persistent, then resorption continues, and if the tooth tissue is irretrievably damaged, complete resorption may occur.
Carrier Status: Tooth resorption is a dental condition where the body starts to break down and absorb the structures of a tooth. Unlike some genetic disorders, it does not have a defined carrier status. The exact cause of tooth resorption is not fully understood but is thought to be associated with trauma, inflammation, or genetic predispositions.
Mechanism: Tooth resorption, also known as dental resorption, involves the loss of dental hard tissue, primarily dentin and cementum, and sometimes enamel. The mechanisms and molecular mechanisms driving this process are as follows:

### Mechanism
1. **Initiation**: Tooth resorption is often initiated by trauma, infection, orthodontic treatment, or idiopathic factors.
2. **Inflammation**: The affected area may experience an inflammatory response, recruiting osteoclast-like cells.
3. **Resorption**: Specialized cells called odontoclasts (similar to osteoclasts) break down and absorb the tooth's mineralized tissue.
4. **Repair**: Depending on the severity, the body might deposit reparative dentin to counteract the resorptive process, though such repair is often incomplete.

### Molecular Mechanisms
1. **Cytokines and Chemokines**: Pro-inflammatory cytokines such as TNF-α, IL-1, and IL-6 play a role in recruiting and activating odontoclasts.
2. **RANK/RANKL/OPG Pathway**:
- **RANK (Receptor Activator of Nuclear Factor-kappa B)** on odontoclast precursors binds to RANKL (RANK Ligand) expressed by osteoblasts and periodontal ligament cells.
- This binding promotes the differentiation, activation, and survival of odontoclasts.
- OPG (Osteoprotegerin) acts as a decoy receptor for RANKL, inhibiting its interaction with RANK and thus the resorption process.
3. **Matrix Metalloproteinases (MMPs)**: These enzymes degrade the collagen matrix and other non-mineralized components of tooth structure, facilitating resorption.
4. **Cathepsin K**: An enzyme produced by odontoclasts that helps break down the mineral matrix of the tooth.

Understanding these mechanisms can aid in developing targeted therapies to prevent or mitigate tooth resorption.
Treatment: Tooth resorption, also known as root resorption, is a process where the structure of a tooth is broken down and absorbed by the body.

**Treatment:**
The treatment for tooth resorption depends on the extent and location of the resorption:

1. **Observation:** In minor cases where resorption is detected early and is not progressing, a dentist may recommend periodic monitoring.
2. **Restorative Treatment:** Filling cavities or applying crowns can help restore the tooth structure if the resorption is not extensive.
3. **Endodontic Treatment:** If the resorption has affected the pulp of the tooth, a root canal may be necessary to remove the damaged tissue and save the tooth.
4. **Extraction:** In severe cases where the structural integrity of the tooth is compromised and cannot be restored, the tooth may need to be extracted.
5. **Surgery:** In some cases, surgical intervention might be needed to remove the resorptive tissue and repair the damage.

It’s important to diagnose and address tooth resorption early to prevent extensive damage and more complicated treatments. Regular dental check-ups are key to catching it in its early stages.
Compassionate Use Treatment: Tooth resorption, also known as root resorption, occurs when the body breaks down and absorbs the structure of a tooth. There is limited information on compassionate use treatments specifically for tooth resorption, but some off-label or experimental treatments have been explored. These include:

1. **Bisphosphonates**: Typically used in treating osteoporosis, these drugs may help slow the resorption process by inhibiting osteoclast activity.

2. **Denosumab**: An antibody that inhibits bone resorption, it has been investigated in some experimental contexts for its potential to curb tooth resorption.

3. **Steroids**: Sometimes used off-label to reduce inflammation and slow the resorption process, though their effectiveness varies.

4. **Laser therapy**: Emerging research suggests that certain types of lasers might help in stopping or slowing the resorption process by affecting cellular activity.

These treatments are considered experimental and should be discussed with a dental professional to evaluate their potential benefits and risks.
Lifestyle Recommendations: To manage and potentially prevent tooth resorption, consider the following lifestyle recommendations:

1. **Maintain Good Oral Hygiene**: Brush your teeth at least twice a day with fluoride toothpaste and floss daily. This helps to remove plaque and bacteria that could contribute to dental issues.

2. **Regular Dental Checkups**: Visit your dentist regularly for checkups and cleanings. Early detection of tooth resorption can lead to better outcomes.

3. **Balanced Diet**: Eat a well-balanced diet rich in vitamins and minerals. Calcium and vitamin D are particularly important for maintaining strong teeth and bones.

4. **Avoid Trauma to Teeth**: Wear mouthguards during sports or activities that could lead to dental injuries. Avoid habits like clenching or grinding teeth, which can contribute to wear and damage.

5. **Limit Sugary and Acidic Foods**: Reduce consumption of foods and drinks high in sugar and acidity, as they can contribute to dental decay and erosion.

6. **Quit Smoking**: Smoking can exacerbate dental problems, including gum disease and tooth loss, which can compound the effects of tooth resorption.

7. **Stay Hydrated**: Drink plenty of water to help maintain saliva production, which is important for neutralizing acids and keeping your mouth clean.

If you notice any symptoms of tooth resorption, such as pain, sensitivity, or visible changes in your teeth, consult your dentist promptly for evaluation and appropriate treatment.
Medication: Tooth resorption is a process where the structure of a tooth begins to break down and is absorbed by the body. Treatment options primarily depend on the extent and location of the resorption. Medications are not typically used to treat tooth resorption directly. Instead, treatments may include:

1. **Monitoring**: In cases of mild external resorption, the tooth may simply be monitored over time.
2. **Restorative treatment**: Fillings, crowns, or other dental restorations may be employed to repair the damaged area.
3. **Root canal therapy**: If resorption affects the pulp of the tooth, a root canal may be necessary to remove the diseased tissue.
4. **Extraction**: In severe cases where the tooth structure is significantly compromised, extraction followed by replacement options like dental implants or bridges may be necessary.

Prompt consultation with a dental professional is crucial for an accurate diagnosis and appropriate treatment plan.
Repurposable Drugs: Tooth resorption, also known as root resorption, involves the breakdown or destruction of the tooth structure, including the root, by the body's own cells. There is limited specific information on repurposable drugs directly targeting tooth resorption. Treatments typically focus on addressing the underlying cause, monitoring progression, or performing surgical intervention if necessary. Commonly used approaches include:

- **Anti-inflammatory Medications:** Nonsteroidal anti-inflammatory drugs (NSAIDs) may help manage pain and inflammation associated with the condition.
- **Bisphosphonates:** These drugs, primarily used to treat osteoporosis, have been studied for their potential to inhibit resorptive processes.
- **Antibiotics:** If an infection is present, appropriate antibiotics may be prescribed.

Further research is needed to identify and validate more specific repurposable drugs for tooth resorption.
Metabolites: For tooth resorption, there currently isn't enough detailed information about specific metabolites that might be involved. Tooth resorption is a condition where the body breaks down and absorbs the mineralized tissue of the tooth, and it's often detected incidentally through dental X-rays or during routine examinations. Further research is needed to identify the metabolic pathways and specific metabolites associated with this condition.
Nutraceuticals: Nutraceuticals are not typically used as a primary treatment for tooth resorption. Treatment usually involves addressing the underlying causes, such as dental trauma or inflammation, and may include procedures like root canal therapy or tooth extraction. Nutraceuticals can potentially be used as supportive therapy to enhance overall dental health and reduce inflammation. Always consult with a dental professional for appropriate diagnosis and treatment options.
Peptides: Tooth resorption is the process by which the structure of a tooth is broken down and absorbed by the body. This condition can affect any part of the tooth, including the root or the crown.

Peptides: Peptides are short chains of amino acids that can play various roles in the body, including signaling and regulatory functions. In the context of tooth resorption, specific peptides could potentially be involved in the signaling pathways that regulate the activity of cells responsible for resorbing dental tissue.

Nan: "Nan" could refer to nanotechnology, which involves the use of extremely small particles and devices. In dentistry, nanotechnology could be employed to create advanced materials and treatments that can better target and treat conditions like tooth resorption at a molecular or cellular level. Potential applications include targeted drug delivery systems, advanced biomaterials for tooth repair, or improved imaging techniques for early detection.
