the aim of this case report was to present a case of multiple idiopathic apical root resorption which is a rare condition in a 17-year-old adult male. external root resorption of the permanent teeth is a multifactorial process. well-recognized causes of apical root resorption in permanent teeth include orthodontic therapy, trauma, periapical or periodontal inflammation, tumors, cysts, occlusal ...

A commonly observed occurrence in pediatric dentistry is that of pulp chamber and root canal obliteration secondary to trauma. Ttn’s report describes a case of calcific metamorphosis in a primary incisor reversing and undergoing internal resorption.

Received: 10/Jan/2009, Accepted: 18/Mar/2009 Objective: Receptor activator for nuclear factor kappa B ligand (RANKL), which is also called osteoclast differentiation factor, is an important regulatory factor in osteoclast maturation. Knowledge of bone and cementum similarities and RANKL role in bone resorption suggests the possibility of a role for this protein in root resorption induced by ort...

A n investigation of mineral density surrounding lacunar resorption sites in cases of both internal and external root resorption, was carried out on 37 human primary and permanent teeth. In addition, equivalent areas of the roots of 14 normal appearing teeth were studied for comparison. Thirty-two of the teeth were analyzed using microradiographic and microhardness techniques and the remainder ...

Treating pathological defects that are caused by resorption in teeth can be challenging. The task is complicated further if the resorption extends beyond the restrains of the root. The aim of this report is to describe a case of extensive internal tunneling resorption (ITR) associated with invasive cervical resorption (ICR) in a maxillary right lateral incisor and its nonsurgical treatment. A 2...

# Department of Conservative Dentistry and Endodontics, Institute of Dental Studies and Technologies, Modinagar, Ghaziabad. ABSTRACT Tooth-bleaching techniques today mostly employ hydrogen peroxide as the active agent. It is applied directly, or produced in a chemical reaction from sodium perborate or carbamide peroxide. More than 90% of success rate has been reported for intracoronal bleaching...

Objectives Root resorption is a dangerous side effect in orthodontics, and maxillary incisors are at the highest risk for root resorption. It is important to understand optimal force considerations for patients with altered root lengths.The purpose of this study was to investigate the effects of root length on stress distribution on roots by means of three dimensional fi...

background: the aim of this study was to evaluate the hypothesis that budesonide increases the susceptibility of teeth to root resorption during the course of orthodontic treatment. materials and methods: a randomized controlled trial design (animal study) was employed. budesonide was administered in test group for 14 days during which orthodontic force was applied to upper right molar. afterwa...
