Background: Tooth extraction is a common dentistry procedure followed by alveolar bone resorption. Trauma that occurs in tooth will induce exaggerating inflammatory process, leads to increased Bone resorption can be minimized administering combination of Nigella sativa extract and bovine graft. The material expected increase the woven area formation speed up remodeling process. Purpose: To dete...

AIM To describe the management of external invasive resorption using mineral trioxide aggregate (MTA). SUMMARY External invasive root resorption may occur as a consequence of trauma, orthodontic treatment, intracoronal bleaching and surgical procedures, and may lead to the progressive and destructive loss of tooth structure. Depending on the extent of the resorptive process, different treatme...

This case report describes the endodontic treatment of an idiopathic perforated internal root resorption. A 24-year-old male Malay patient presented with internal root resorption of two of his anterior teeth. The medical history was non-contributory and he had no history of traumatic injury or orthodontic treatment. Cone-beam computed tomography (CBCT) determined the nature, location and severi...

Primary hyperoxaluria is a rare, inherited autosomal recessive disease caused by defects in the metabolism of glyoxylate. Oral manifestations of hyperoxaluria are rare. However, bone and tooth resorption may be the result of chronic inflammation and the presence of osteoclastic cells surrounding the oxalate crystal deposit. A deposit of calcium oxalate in the periodontium was identified in a pa...

severe traumatic injuries to immature teeth often cause damage to periodontal ligament as well as dental pulp; pulp necrosis, root resorption and subsequent apical lesion are common consequences. this article reports the surgical management of an infected immature maxillary central incisor associated with a gigantic periradicular lesion and severe root resorption. the tooth had a history of tra...

Erupting teeth are some of the oldest witnesses of developmental processes in the vertebrate fossil record and provide an important resource for vertebrate cladistics. Here, we have examined a mosasaur jaw fragment from central Texas using ultrathin ground section histology and 3D tomographic imaging to assess features critical for the cladistic placement of mosasaurs among varanoids vs. snakes...

When a tooth sustains a luxation injury, attachment damage of varying degrees will occur. In addition, necrosis of the pulp might result, thereby making the pulp space susceptible to infection. These circumstances can lead to root resorption. Treatment for root resorption includes preventing it by avoiding causes of root surface injury, minimizing initial inflammation, and reversing resorption.

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. The initiating factor in internal root resorption is thought to be trauma or chronic pulpal inflammation, but other etiological fac...

Intracoronal radiolucencies in unerupted permanent teeth had been described previously as caries, carieslike lesions," and developmental in origin.More recent reports describe these lesions as resorption of the crown of unerupted permanent teeth' found as an incidental radiographic finding, rarely in more than one tooth in the same patient.-' These often go unnoticed until eruption and then are...

In osteichthyans (bony fishes) the dentition is characterized by marginal tooth rows replaced basal resorption. Basal resorption was present in stem osteichthyan Andreolepis, which also possessed overgrowing tooth-shaped odontodes, a possible intermediate state between external odontodes and teeth. however, lacked enlarged found more advanced osteichthyans, how these evolved from condition unkn...
