objective(s): this study aimed to investigate the role and the possible mechanisms involved in the immunoregulation of experimental periodontitis by th17/treg. materials and methods: experimental periodontitis was established by silk thread ligation with porphyromonasgingivalis daubing in the bilateral maxillary second molar of male sprague-dawley (sd) rats. alveolar bones were scanned by micro...

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 ...

normal 0 false false false en-us x-none fa microsoftinternetexplorer4 introduction : alveolar bone level is changed due to the balance between bone formation and resorption. radiographic examination has an important role in the diagnosis and treatment of periodontal diseases. this study was performed to compare the accuracy of vertical bitewing and periapical radiography in anterior mandibular ...

internal resorption is rare in permanent teeth. treatment is usually performed through warm gutta-percha technique. if the resorptive process perforates the root, treatment may be more difficult and is usually performed via surgical approach. non-surgical repair of a perforating internal root resorption with mta was conducted in this case. before repairing the resorption, a master gutta-percha ...

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...
