What is Cemental tear?

What is Cemental tear?

Cemental tear is defined as cementum fragment completely or partially detached from the root surface, and it has been associated with localized rapid periodontal breakdown. Although history of trauma and/or attrition may be risk factors, the etiopathology of cemental tear remains unknown.

What causes Cemental tear?

Possible predisposing factors of cemental tear include gender, age, tooth type, traumatic occlusion, and mainly in non-endodontically-treated teeth. Clinically, it shows a unitary periodontal pocket and may present signs and symptoms simulating of localized periodontitis or apical periodontitis.

What is cervical root resorption?

Cervical invasive root resorption is a type of external inflammatory root resorption that is relatively uncommon and aggressive, and leads to loss of tooth structure. A diagnosis of cervical invasive root resorption depends on careful routine clinical and radiographic examinations.

How is cervical root resorption treated?

When ICR is diagnosed, generally, three choices are considerable for treatment: No treatment with eventual extraction when the tooth becomes symptomatic; Immediate extraction; or. Access, debridement, and restoration of the resorptive lesion.

Can chemo cause tooth resorption?

Developmental abnormalities resulting after malignant chemotherapy occur when the patient is treated prior to six years of age [5]. Diminished root surface area due to radiation exposure is the reason for early tooth loss.

What are the types of denticles?

According to Structure:

• True Pulp stone or Denticle: These are very rare and are a True denticle is made up of dentin and is lined by odontoblasts.
• False Pulp stone or Denticle: These are called false denticles as they appear within bundles of collagen fibers appearing as concentric layers of calcified tissue.

Where are denticles found?

Denticles originate in the tooth pulp but can become partly or entirely incorporated into the dentin layer. Denticles originate from small budlike projections emanating from the epithelial sheath, immediately adjacent to the pulp chamber.

Are pulp stones rare?

True pulp stones are quite rare. On the other hand, false pulp stones are made up of concentric layers of mineralised tissue around blood thrombi, collagen fibres, or dying and dead cells.

Do pulp stones cause pain?

Pulp stones appear to have no clinical significance. They are not believed to be a source of pain and are not associated with any form of pulpitis. They may, however, be problematic during endodontic therapy of nonvital teeth.

What causes cervical root resorption?

External cervical resorption is caused, almost exclusively, by dental trauma, especially concussion, and it is a dental disease to be accurately diagnosed and treated by an endodontist, although the vast majority of the cases is at first diagnosed by an orthodontist.

What causes invasive cervical resorption?

The etiology of cervical invasive root resorption is still not completely clear. Many etiologic factors have been reported, including trauma, orthodontic treatment, bleaching, surgical procedures, and inflammation.

What causes tooth resorption in adults?

In most cases it is due to a physical injury to the tooth, as from an impact, chemical, or burn. The trauma leads to inflammation that in turn results in resorption. Other causes include pulp necrosis, periodontal treatment, orthodontics, or poorly done, non-professional tooth whitening.

What are true denticles?

True Pulp stone or Denticle: These are very rare and are a True denticle is made up of dentin and is lined by odontoblasts. These are located close to the apical foramen. The presence of the remnants of epithelial root sheath within the pulp leads to the development of a True denticle.

What are denticles in dentistry?

Denticles are pulp degenerations in the form of. calcified deposits of mineral salts, usually found in. molars and lower incisors, as well as in impacted. teeth and deciduous molars.

What is the function of denticles?

Shark skin is covered by tiny flat V-shaped scales, called dermal denticles, that are more like teeth than fish scales. These denticles decrease drag and turbulence, allowing the shark to swim faster and more quietly.

What are denticles made of?

They are made of an inner pulp cavity that contains blood vessels, nerves, and connective tissue; and an outside layer of dentine made of a mineral called apatite.
