Differential expression of microRNAs in human External Cervical Root Resorption
External Cervical Root Resorption (ECR) is an inflammatory condition that involves localized destruction of tooth structure, often resulting in tooth loss. ECR has been reported since the 1900s, however a complete understanding of its pathogenicity is lacking. Currently no target therapies are …

Factors Associated with Orthodontically Induced Apical Root Resorption of Maxillary Incisors
<p>Introduction: Resorption of root apices is a ubiquitous occurrence in orthodontic treatment. Although most occurrence of resorption during orthodontic treatment is clinically inconsequential, a small percentage of patients have a severe amount of root structure that is lost. There are factors …

Fractal Analysis to Detect Surface Roughness Changes After Fatique Loading in the Canine Mandibular Incisor - A Pilot Study
… from orthodontic treatment is iatrogenic root resorption. Experimentally, histological sections are usually employed to study root resorption utilizing special staining techniques. Although this has been shown effective for decades, results are limited to extracted teeth. Clinically, root …

The Effect of Corticision on The Rate of Orthodontic Tooth Movement in Rats
… decreases risk of caries, periodontal disease, root resorption, and increases patient satisfaction. Orthodontic tooth movement (OTM) is a result of bone resorption and apposition; factors influencing the rate at which these processes take place may affect OTM. Various attempts have been made to …

Root Damage in Mechanically Fatigued Teeth
According to one theory of root resorption, occlusal trauma during orthodontic tooth movement damages the cementum covering the root dentin. The body detects the exposed dentin and seeks to remove it, and the result is root resorption. This experiment will explore an aspect of this theory by …
