Simulated Root Resorption: A New Study Model
نویسندگان
چکیده
INTRODUCTION The aim of this innovative study was to regenerate a condition that makes it possible to carry out researches in the field on a variety of resorption. MATERIALS AND METHODS In order to develop apical resorption, the root canals of selected teeth were instrumented and then drilled with #4 Gates Glidden drills. In the next stage, the teeth were submerged in melted rose wax up to 3 mm to the apex. The waxed teeth were submerged in 20% sulfuric acid for 4 days. After that, all samples were evaluated under stereomicroscope and also the SEM. RESULTS Images showed areas with different pattern of resorption in root apex and entire root canals in all samples. CONCLUSION Simulation of the root resorption can be helpful in many experimental studies.

Comparison of Accuracy and Observer Agreement in the Detection of Simulated External Root Resorption Using Conventional Digital Radiography and Digitally Filtered Radiography
Introduction: External root resorption is a clinical problem that often cannot be detected clinically. Thus, radiography plays a crucial role in its diagnosis. However, optimal radiographic quality with minimal radiation exposure {2.1 [EN] Verify English word/phrase choice} is an important factor in selecting the appropriate radiographic technique. The aim of this study was the comparison of ac...

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...
متن کاملIn vitro comparison of cone beam computed tomography with different voxel sizes for detection of simulated external root resorption.
The present study compared the efficacy of cone beam computed tomography using different voxel sizes in the diagnosis of simulated external root resorption. The presence or absence of simulated defects on buccal, mesial and distal root surfaces of 20 premolars was evaluated. The defects were small (0.26 mm in diameter and 0.08 mm deep), medium (0.62 mm in diameter and 0.19 mm deep) and large (1...
